Despite the scientific consensus on climate change, drastic uncertainties remain. Crucial questions about changes in regional climate, trends of extreme events such as heat waves, heavy precipitation, and mega-storms, and understanding how climate varied in the distant past, must be answered in order to improve predictions, assess impacts and vulnerability, and aid mitigation and adaptation efforts. Machine learning can help answer such questions and shed light on climate change. Similar to the case of bioinformatics, the study of climate change provides a data-rich scientific domain in which cutting-edge tools from machine learning can make a major impact. Further, such questions give rise to new challenges for the design of machine learning algorithms. This tutorial will give an overview of impactful open questions about climate change, highlight recent successes of machine learning in this domain, and outline significant remaining challenges. Machine learning problems in climate change include prediction, reconstruction, causal attribution, analysis of quantiles and extremes, and exploratory data analysis. Challenges arise because the climate system is extremely complex, comprised of physical processes and their interactions, and the data is massive, high-dimensional, and spatiotemporal, with non-stationarity and potential long-range dependencies over time and space.

As a result the whole environment got polluted and degraded. In view of the colossal damage done to the environment, governments and public are now concerned about the environmental impacts of developmental activities. So, to assess the environmental impacts, the mechanism of Environmental Impact Assessment also known as EIA was introduced. EIA is a tool to anticipate the likely environmental impacts that may arise out of the proposed developmental activities and suggest measures and strategies to reduce them. EIA was introduced in India in 1978, with respect to river valley projects. Later the EIA legislation was enhanced to include other developmental sections since 1941. EIA comes under Notification on Environmental Impact Assessment (EIA) of developmental projects 1994 under the provisions of Environment (Protection) Act, 1986. Besides EIA, the Government of India under Environment (Protection) Act 1986 issued a number of other notifications, which are related to environmental impact assessment. EIA is now mandatory for 30 categories of projects, and these projects get Environmental Clearance (EC) only after the EIA requirements are fulfilled. Environmental clearance or the ‘go ahead’ signal is granted by the Impact Assessment Agency in the Ministry of Environment and Forests, Government of India. Projects that require clearance from central government can be broadly categorized into the following sectors • Industries • Mining • Thermal power plants • River valley projects • Infrastructure • Coastal Regulation Zone and • Nuclear power projects The important aspects of EIA are risk assessment, environmental management and Post product monitoring. Functions of EIA is to 1. Serve as a primary environmental tool with clear provisions. 2. Apply consistently to all proposals with potential environmental impacts. 3. Use scientific practice and suggest strategies for mitigation. 4. Address all possible factors such as short term, long term, small scale and large scale effects. 5. Consider sustainable aspects such as capacity for assimilation, carrying capacity, biodiversity protection etc... 6. Lay down a flexible approach for public involvement 7. Have a built-in mechanism of follow up and feedback. 8. Include mechanisms for monitoring, auditing and evaluation. In order to carry out an environmental impact assessment, the following are essential: 1. Assessment of existing environmental status. 2. Assessment of various factors of ecosystem (air, water, land, biological). 3. Analysis of adverse environmental impacts of the proposed project to be started. 4. Impact on people in the neighborhood. Benefits of EIA • EIA provides a cost effective method to eliminate or minimize the adverse impact of developmental projects. • EIA enables the decision makers to analyses the effect of developmental activities on the environment well before the developmental project is implemented. • EIA encourages the adaptation of mitigation strategies in the developmental plan. • EIA makes sure that the developmental plan is environmentally sound and within limits of the capacity of assimilation and regeneration of the ecosystem. • EIA links environment with development. The goal is to ensure environmentally safe and sustainable development. Environmental Components of EIA: The EIA process looks into the following components of the environment: • Air environment • Noise component : • Water environment • Biological environment • Land environment EIA Process and Procedures Steps in Preparation of EIA report • Collection of baseline data from primary and secondary sources; • Prediction of impacts based on past experience and mathematical modelling; • Evolution of impacts versus evaluation of net cost benefit; • Preparation of environmental management plans to reduce the impacts to the minimum; • Quantitative estimation of financial cost of monitoring plan and the mitigation measures. Environment Management Plan • Delineation of mitigation measures including prevention and control for each environmental component, rehabilitation and resettlement plan. EIA process: EIA process is cyclical with interaction between the various steps. 1. Screening 2. Scoping 3. Collection of baseline data 4. Impact prediction 5. Mitigation measures and EIA report 6. Public hearing 7. Decision making 8. Assessment of Alternatives, Delineation of Mitigation Measures and Environmental Impact Assessment Report 9. Risk assessment

This webinar was held as a part of the Climate Change Science and Management Webinar Series, a partnership between the USGS National Climate Change and Wildlife Science Center and the FWS National Conservation Training Center. Webinar Description: Many federal agencies are currently striving to plan for climate change adaptation. Researchers for this project explored 1) the degree to which federal resource managers believe that climate change adaptation is important in their work and 2) the degree to which these managers are connected to each other and to a broader research community that can provide a scientific basis for climate change adaptation actions. The project consisted of a social network analysis of federal resource managers in the regions encompassed by the Southwest and North Central CSCs. Methods for this project included an online survey targeting resource managers from the Bureau of Land Management, Forest Service, National Park Service and Fish and Wildlife Service, as well as a snowball survey to garner opinions from people within academic, nongovernmental and federal research organizations (e.g., USGS), as well as from state resource managers. This study resulted in a number of different findings, including an overall strong concern for climate change impacts on natural resources among resource managers and a varying degree of connectedness between resource management agencies and research units.

Title: Biodiversity as a metric of ecosystem resilience to climate change Presenter: Helen Poulos, PhD Date: March 13th, 2014 at 11am CST Abstract: Shifting diversity patterns and species turnover are fundamental concerns about how climate change will influence desert ecosystems. Scientists, managers, and-policy makers are searching for metrics to assist in the prediction of ecosystem responses to climate change. Temporal variation in landscape and regional-scale diversity can provide insights on the fragility or resilience of plant and animal communities in the Southwest to changing climates. This talk will explore the suite of diversity metrics and tools for measuring species turnover that are available for monitoring ecosystem change over time through the lens of biodiversity. About the Presenter: Helen's research focuses on developing risk management and decision support tools for sustainable forest and ecosystem management. She has been working in the Southwest for the last 14 years exploring local-, landscape, and regional-scale tree diversity patterns and species turnover along environmental gradients of Sky Island systems. Helen is both a field biologist and a data-mining expert, which she uses for developing decision support tools that can be readily implemented by policy-makers and on the ground by land managers. She holds a Master's degree in Geography from The Pennsylvania State University and a PhD from The Yale School of Forestry and Environmental Studies. She is currently part of Wesleyan University's College of the Environment.

http://gallery.usgs.gov/videos/697 The effects of climate change on fish habitat will be scale-and system-dependent. Our work demonstrates how climate change affects fish habitat nationwide, and stream flow, water temperature, and coldwater lakes in the Upper Midwest. Projected changes in fish habitat varied across ecoregions nationally. The future regional climate will likely alter hydrologic and thermal regimes suitable to the fish species in that region. The results show that the scale at which we assess climate change impacts may influence decisions made, and that the different attributes of lakes and streams require different approaches to determine climate and land use change effects on fish habitat.

Effects of anthropogenic climate change already manifest themselves in the Pacific Northwest through reduced winter snow accumulation at lower elevations and earlier spring melt. As the climate warms, the Columbia River, whose flow regime is heavily dependent on seasonal snow melt, is likely to experience significant changes in the timing of its seasonal hydrograph and possibly in total flow volume. We report on a new study co-funded by the Bonneville Power Administration to update and enhance an existing climate change streamflow data set developed by the University of Washington Climate Impacts Group in 2009-2010. Our new study is based on the RCP4.5 and RCP8.5 climate projections from the Coupled Model Intercomparison Project Version 5 (CMIP5). In contrast to earlier studies, we are using a suite of three hydrologic models, the Variable Infiltration Capacity (VIC) model, the Unified Land Model and the Precipitation Runoff Modeling System, each implemented at 1/16 degree (~6 km) over the Pacific Northwest. In addition, we will use multiple statistical downscaling methods based on the output from a subset of 10 CMIP5 global climate models (GCMs). The use of multiple hydrologic models, downscaling methods and GCMs is motivated by the need to assess the impact of methodological choices in the modeling process on projected changes in Columbia River flows. We discuss the implementation of the three hydrologic models as well as our development of a glacier model for VIC, which is intended to better represent the effects of climate change on streamflows from the Columbia River headwaters region. Finally, we report on our application of a new auto-calibration method that uses an inverse routing scheme to develop spatially-distributed runoff fields from naturalized flows at gauge locations. This allows us to calibrate the hydrologic models at the level of the individual grid cell rather than sub-basin.

Today Armenia has turned into an ecological disaster zone as a result of the catastrophic impact of the anthropogenic pressure. The wide-ranging and hasty mining activities, mass forest logging (In Armenia approximately 1 million cubic meters of timber, the average of 8000ha of forest, is illegally logged), urbanization, the pollution of rivers and humid areas, poaching and illegal animal trade, the big volumes of fishing have led to the degradation of the environment, climate change, decrease in specie populations and disruption of ecological processes. Hundreds of flora and fauna species have appeared on the brink of extinction. According to the data published by the UN, 82% of Armenia?s territory is under the threat of desertification. Due to the deterioration of the air quality the number of respiratory diseases has doubled, and the number of anomalous births is on the rise, too (According to a 2005 World Health Organization report, Armenia ranks second among CIS countries by anomalous births and similar problems, only Kyrgyzstan is worse off). This gruesome picture of the tormented Mother Nature with all its dreadful consequences must sober the Armenian people. Human indifference cannot be justified either by social situation, or by economic interest or by political strategy. Humans are destroying their only supporting platform; humans have forgotten about nature, humans have stopped loving nature. We, the organizers of the exhibition, are a group of young environmental activists united by our love and caring attitude towards nature. We are doing our best to react to the urgent ecological issues through raising the awareness of the public, developing "environmental mindset" and various other activities. Since 2006 we have organized numerous bicycle campaigns both in Yerevan and outside the capital city which have been aimed at the promotion of bicycle as an environmentally friendly means of transportation as well as at the encouragement of healthy lifestyles. The destruction of a natural monument called Garni's "Stone Symphony" was halted following our effective intervention (bicycle ride to Garni, protest march). In addition, we deal with animal protection issues, we try to combat violence against animals, animal abuse, animal killings, and we fight for animal rights . The most painful and the hottest ecological issue of our days is the outrageous project of launching the exploitation of the Teghut copper-molybdenum minefield. At least 600ha of forest (in other words, 200.000 trees) will be felled as a result of operating the mine. 55.000 rare and 45.000 valuable trees from Teghut forests as well as Red-listed flora and fauna species will once and for all disappear from those areas. Of special concern are the production tailing and their impact that will emerge as a consequence of mine operation. The environment and human health will suffer major losses because of the infiltration of copper, molybdenum, sulfur, zinc, lead and other poisonous metals into the soil, water and air basins. Let us preserve the nature; it is the guarantee of our life and the life of the coming generations, isn't it? Let us not destroy and let others destroy! Let us not pollute and let others pollute! Let us not defile and let others defile MOTHER NATURE? Each and all of us can, have the power and are obliged to be concerned about, take care of, preserve and protect NATURE!

Raising awareness and creating a connection with the north pole is why Maarten wants to talk about these changes and their causes during his TED-talk. Dr Maarten Loonen is a polar researcher who has been travelling to Spitsbergen for over 25 years to study the behaviour of migratory birds and changes in their living conditions. The Polar regions are unique for researchers as rises in temperature and the consequences for humans, animals and plants are extra visible here. On Spitsbergen, Loonen and other Groningen scientists are studying whale hunting, tourism, mining, ecosystems and the consequences of climate change for migratory birds. In 2014, Loonen was one of the researchers of the University of Groningen that were invited by the Dutch Navy to join an expedition to Jan Mayen island. This was a unique opportunity for the researchers to visit this isolated island. The multidisciplinary research team concentrated on archaeology and biology. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

In 2014, the team at Western Australia Iron Ore identified that digital innovation could help enhance environmental outcomes and developed the Big Data for Biodiversity project. The project provided a landscape-scale, cumulative impact assessment of BHP Iron Ore’s ‘Life of Asset’ plan. The team developed a user-friendly tool that provided a quantitative assessment across various temporal scales, spanning approximately 100 years of operating life. This information is helping the business to make informed decisions now because they have the ability to begin with the end in mind. By taking a ‘big picture’ approach, the project team has been able to quantify the key potential impacts that are most important on a regional scale. They found that the biggest potential threats to protected species were grazing and climate change, and have made their results publicly available to help assist governments, communities and industry, and effectively protect our country’s significant flora and fauna species.

SOUNDBITE (English): Dan Blumstein, UCLA Ecology Professor: "In our valley, in recent history, it is warmer in the spring and there is more spring snow pack. Both of these things seemingly influence the marmots. The working hypothesis that we are trying to evaluate better is that marmots, the timing of marmot emergence is based on spring temperatures. So if it is warmer, earlier then marmots seemingly emerge earlier. In our valley, in the spring, we also have more snow so there is a deeper snow pack. So when marmots emerge earlier through a deeper snow pack they have a longer time to wait before vegetation grows up and while they are out there and the place is covered with snow, the coyotes are out eating the marmots. So here is sort of a double whammy - they have to survive longer without eating because there is no food for them to eat - they don't save food they store fat and suddenly the predators are out picking off these brown little spots on the snow that have no place to run too." 10.

SOUNDBITE (English): Johannes Foufopoulos, University of Michigan Professor of Natural Resources and Environment: "The trend in the last few years seems that it has been getting both warmer and drier and at the same time what we have been seeing is the sparrow population decreasing. When I originally came to this site we picked this area because the bird population was really dense, there were lots of birds it was a good study population. These days there aren't as many birds around. You work in these ecosystems you really care about them some extent you really invest a lot of energy doing research here and it is sad to see them slowly disappear and get degraded. So definitely there is an emotional component to it but there is also a very practical component, you can't do much research if your birds are gone, right?" 15.

Although family members of Mohammed Saleh Qayed Taeiman call him a normal sixth grader who was eager to have fun, the US military in January unleashed a deadly drone strike that killed the “al-Qaeda militant” along with two others. Taeiman’s father and brother were in 2012 similarly killed by US strikes, and another brother was wounded in a different attack, dealing multiple blows to the family even before the death of the young boy. With this in mind, RT’s Ben Swann and Reema Abu Hamdieh speak in an exclusive interview with Mohammed’s cousin, Hussein Taeiman.

https://media.ccc.de/v/34c3-9178-on_the_prospects_and_challenges_of_weather_and_climate_modeling_at_convection-resolving_resolution The representation of thunderstorms (deep convection) and rain showers in climate models represents a major challenge, as this process is usually approximated with semi-empirical parameterizations due to the lack of appropriate computational resolution. Climate simulations using kilometer-scale horizontal resolution allow explicitly resolving deep convection and thus allow for an improved representation of the water cycle. We present a set of such simulations covering Europe and global computational domains. Finally, we discuss challenges and prospects climate modelers face on heterogeneous supercomputers architectures. Today the evidence for global climate change is unequivocal, and the human influence is clear. Therefore the focus of young researchers has shifted from assessing whether the Planet is warming towards envisioning how a warmer world might look like. For instance, basic physical principles suggest that the hydrological cycle of Planet Earth will likely undergo dramatic changes. However, understanding and describing the involved processes, estimating future changes, and assessing the underlying uncertainties has proven to be difficult and complex. In this effort, numerical simulations of the weather and climate system are a useful research tool. Weather and climate modeling involves solving the governing equations of atmospheric motion on a numerical mesh and employing semi-empirical parameterizations that treat the processes not represented explicitly. For example, the parameterizations typically include treatments for thunderstorms and rain showers (deep convection). These processes are fundamental to the climate system since they vertically redistribute moisture, heat, and momentum, but so far they could not be resolved explicitly, due to the coarse gird spacing of the mesh (resolution) employed in the current generation of climate models. In the recent year's power constrains in the domain of supercomputing have lead to heterogeneous node designs mixing conventional multi-core processors and accelerators such as graphics processing units (GPU’s). These machines posses properties beneficial for weather and climate codes and hence allow refining the resolution of the involved computational mesh to the kilometer scale. Convective clouds can then be represented explicitly (convection-resolving) and the models can be formulated much closer to physical first principles. However, to exploit the capabilities of these supercomputers, model codes have to be ported, a challenging task the weather and climate modeling community is struggling with. We discuss prospects and challenges climate modelers face on these new supercomputers and highlight the potential for addressing key open science questions. The presentation is illustrated with simulations recently accomplished using a new version of the Consortium for Small-Scale Modeling weather and climate model (COSMO), capable of exploiting these heterogeneous supercomputer architectures. Using results form a then-year-long climate simulation on a computational domain covering Europe (1536x1536x60 grid points) we highlight some of the added value of the approach regarding the representation of precipitation processes. Furthermore, we explore the gap between the currently established regional simulations and global simulations by scaling the GPU accelerated version of the COSMO model to a near-global computational domain.

Talk given at Full Stack Fest 2017: https://fullstackfest.com IoT is too often discussed in the abstract. What does it really mean to build a second internet? What does it mean to create an internet out of distributed, sensing machines which talk to each other? In this talk, I'll show you how I'm using connected devices and distributed sensor data on the energy grid to fight climate change. The true full stack is every part of the internet– the client side, the server, the hardware. But we're used to seeing that internet via screens and human interfaces. Let me show you the internet of machines, and how coding for this second internet directly impacts the world. Kelsey Breseman is fighting climate change with engineering as a founder of HC3.io. She is also an engineer and Steering Committee member of the Tessel Project —an open source organization whose aim is to empower web developers to enter the connected-devices space. Previously, Kelsey has been involved in developing consumer drones, research on sleep and temperature, implantable vision devices, and devices for lung cancer diagnosis. She has a degree in neural engineering, and is interested in prosthetics, speculative fiction, circus arts, and really long walks.

Truthout staff writer, Dahr Jamail, has written a sobering piece on climate disruption; a disruption accelerated by the world wrought by the industrial revolution. As many climate change deniers like to point out, carbon levels in the air have fluctuated for over four hundred thousand years, and our planet has warmed and cooled due to natural cycles of carbon in our atmosphere. While it's true that carbon levels have waxed and waned over hundreds of thousands of years, we have not seen the rapid spike in carbon levels that's occurred in the last 100 years. From the records climate scientists have, this is unprecedented. And given the proliferation of extreme weather conditions in the last 15-20 years, the evidence that human activity plays a significant role in climate change is, as Jamail notes, unmistakable. For those who think like to say that the "debate" over human-caused climate change is not settled, their protestations are based on other motivations than arguing the finer points of scientific data. In other words, climate change deniers want politicians and voters think that factories, vehicles, aircraft, cattle farming practices, and other carbon emitting activities that humans have a hand in do not contribute to climate change. To admit that they do means the very industries that power industrial economies (namely the fossil fuel industry) will have to be regulated or put out of business in order to keep our planet habitable for humans -- and other life forms we need for our survival.

With contributions from scientists and partners around the world, One Earth, an initiative of the Leonardo DiCaprio Foundation (LDF), has developed a bold, new plan to avert a climate crisis and protect our biosphere. Justin Winters, LDF's Executive Director, explains the three goals humanity needs to achieve by 2050: Transform our energy systems to 100% clean, renewable energy; Protect, connect and restore 50% of our lands and seas; and Shift to regenerative, carbon-negative agriculture globally. At the heart of this effort is a new map of the world called the Global Safety Net, which shows what the world could look like if we achieve these three goals. This vision of a world where both nature and humanity coexist and thrive can only be achieved if activists and communities around the world are connected and strengthened with the resources and solutions to make this global transformation a reality. One Earth is accelerating this transformation through innovative science, radical tools for collaboration, and creative storytelling that will inspire and galvanize our society into action. This talk was delivered at the 2018 National Bioneers Conference.

Session# 67 Mon 22 October 16:30 to 17:30 1 hr Room 1 GoToWebinar.com 854‐927‐907 Webcast URL https://attendee.gotowebinar.com/register/2539419254691109635# Abstract Global Forest Link (globalforestlink.com, GFL), an award‐winning environmental program, engages youth worldwide in active protection of the environment, with the goal of creating a more sustainable future. Forests are extremely important for human health, climate change mitigation, water purification, and for communities’ resilience and sustainability. Forest health monitoring and management require international collaboration, increased awareness of forest threats, a better understanding of forest processes, and practical skills in analyzing and communicating forest information. Initially developed as an education extension of the WRI’s Global Forest Watch platform, the Global Forest Link project has brought together over 1800 students from 100+ schools and youth groups, and 7 countries. Its key objective is to nurture a new generation of world stewards, who are skilled in modern earth observation technologies, data collection and analysis, evidence‐based education, international collaboration, environmental advocacy, and journalism. GFL teaches youth to explore key environmental change issues by integrating space imagery and local data, understand environmental and socio‐economic consequences of forest degradation, and to communicate their findings to peers and communities. These are important skills needed by future environmental advocates capable of formulating and promoting coordinated strategies and solutions to problems that require global cooperation. GFL addresses the UN 2030 Sustainable Development Goals, focusing on Goals 4 (ensure inclusive and equitable education), 13 (combat climate change and its impacts), and 15 (promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss). The project advances best education practices and promotes equitable access to information. GFL methodology and activities lower the barrier to engagement and enable environmental advocacy by youth around the world. The GFL interactive portal provides effective mechanisms for collection, analysis and sharing environmental and social information.

Process-based models of atmosphere-biosphere interactions, along with empirical data mining techniques, are the primary tools used for scaling disparate observations through space and time. In the past few decades they have been developed in tandem with our understanding of ecological theory, resulting in models of various levels of complexity and detail. Model intercomparisons, however, show a large range in model performance, with no clear consensus as to whether model structural error (process mis-representation) or mis-parameterization is to blame. One potential reason for this lies in difficulties in using data sources at different scales to adequately test model performance and the common reliance on uni-variate model validations. Another is the lack of quantification of the uncertainty associated with model projections. In order to advance our ability to make policy-actionable projections of the future evolution of the earth system, we need to address these issues. In this talk I will assess our ability to model land-atmosphere CO2 exchange at different spatial and temporal scales, both in the present climate and under future climate change. The analysis makes heavy use of model-data fusion techniques, which constitute a powerful framework by which to combine models with various data streams. Model benchmarking tools, such as empirical data mining techniques, also provide a strong alternative model evaluation. To illustrate the potential benefits of such an approach, we assess the performance of 17 process-based models of atmosphere-biosphere interactions, and two data mining tools, across 11 long-term eddy covariance forest sites. The results highlight details of model performance often overlooked by conventional model-data comparisons, and quantify the degree of coupling of terrestrial carbon sequestration to climate anomalies at multiple sites and time scales.
