Highlights of the U.S. Global Change Research Program
Climate Science Special Report
The climate of the United States is strongly connected to the changing global climate. The statements below highlight past, current, and projected climate changes for the United States and the globe. Global annually averaged surface air temperature has increased by about 1.8°F (1.0°C) over the last 115 years (1901–2016). This period is now the warmest in the history of modern civilization. The last few years have also seen record-breaking, climate-related weather extremes, and the last three years have been the warmest years on record for the globe. These trends are expected to continue over climate timescales.
This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century. For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.

From Bali To Marrakech: A Decade Of International Climate Negotiations (2017)
MESSAGE FROM THE EXECUTIVE SECRETARY
Since its entry into force in 1994, the United Nations Framework Convention on Climate Change has been at the centre of international efforts to address global warming and the rising risks it represents to people and economies across the globe. The adoption and early entry into force of the Paris Agreement was a monumental achievement that has put every nation on Earth on a clear pathway and with a clear destination for delivering a safer and more secure future.

About this Report
This report summarizes and communicates the results of EPA’s ongoing Climate Change Impacts and Risk Analysis (CIRA) project. The goal of this work is to estimate to what degree climate change impacts and damages to multiple U.S. sectors (e.g., human health, infrastructure, and water resources) may be avoided or reduced in a future with significant global action to reduce GHG emissions, compared to a future in which current emissions continue to grow. Importantly, only a small portion of the impacts of climate change are estimated, and therefore this report captures just some of the total benefits of reducing GHGs.

Well Under 2 Degrees Celsius: Fast Action Policies to Protect People and the Planet from Extreme Climate Change. Report of the Committee to Prevent Extreme Climate Change (2017)
Climate change is becoming an existential threat with warming in excess of 2°C within the next three decades and 4°C to 6°C within the next several decades. Warming of such magnitudes will expose as many as 75% of the world’s population to deadly heat stress in addition to disrupting the climate and weather worldwide. Climate change is an urgent problem requiring urgent solutions. This report lays out urgent and practical solutions that are ready for implementation now, will deliver benefts in the next few critical decades, and places the world on a path to achieving the longterm targets of the Paris Agreement and near-term sustainable development goals.

2017 – Draft of the US Climate Change Report
A draft report by scientists from 13 federal agencies, which has not yet been made public but was obtained by The New York Times, concludes that Americans are feeling the effects of climate change right now. The report was completed this year and is part of the National Climate Assessment, which is congressionally mandated every four years.
Seeking Higher Ground: How To Break The Cycle Of Repeated Flooding With Climate-Smart Flood Insurance Reforms (2017)
The National Flood Insurance Program (NFIP) was designed to help Americans recover from flood disasters, but it can also unintentionally trap homeowners who would prefer to move somewhere safer. Instead of moving, many policyholders find themselves rebuilding their homes again and again. Across the United States, more than 30,000 “severe repetitive loss properties” (SRLPs) have been covered under the NFIP. These properties have flooded an average of five times, according to FEMA data acquired by NRDC through a Freedom of Information Act request.
More and more Americans are living in areas that are vulnerable to flooding and sea level rise.4,5,6 In the face of rising flood risks and damages, the NFIP should provide interested homeowners the option of relocating. This issue brief proposes flood insurance reforms that would make it possible for the owners of repeatedly flooded homes to receive a buyout of their property after a flood, removing the uncertainty that surrounds FEMA’s existing buyout efforts. Under this proposal, homeowners would be able to voluntarily sign up for a buyout before the next flood occurs. If a flood then substantially damages their home, FEMA would quickly provide funding that enables the local government to purchase the flood-prone property and convert it to open space while freeing the owner to relocate.
This year, Congress is debating the future of the NFIP. This presents a critical opportunity to make buyouts of flood-prone properties a more realistic option for more homeowners. With floods and flood damages on the rise, now is the time for climate-smart reforms to the National Flood Insurance Program.

This lawsuit by an anti-immigration group alleges that since Americans have among the highest carbon footprints, allowing immigrants into the US will increase GHG emissions and climate change. This means that immigration has environmental impacts and thus immigration policy changes require an Environmental Impact Statement under NEPA.
