By Paul Voosen , Science.  Excerpt: The  last assessment  of the state of climate science from the United Nations’s Intergovernmental Panel on Climate Change (IPCC), published in its final form 2 years ago, was a monumental effort, with  721 volunteer scientists  synthesizing all available published research. Yesterday, the Department of Energy (DOE)  released  its own climate assessment, as part of a campaign by the U.S. Environmental Protection Agency (EPA) to overturn its landmark endangerment finding from 2009, which found that burning fossil fuels endangers public health and established carbon dioxide as a pollutant EPA could regulate. But the DOE  report —called  A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate —had fewer authors than IPCC’s: just five. ...Climate researchers say the authors cherry-picked evidence and highlighted uncertainties to achieve the net effect of downplaying the impacts of climate ch...

Joint release of the AGU and the AMS.  Excerpt: WASHINGTON — The American Geophysical Union (AGU), the world’s largest association of Earth and space scientists, and the American Meteorological Society (AMS), the professional society for atmospheric and related sciences and services, invite manuscripts for a new, first-of-its-kind special collection focused on climate change in the United States. This catalog of over 29 peer-reviewed journals covers all aspects of climate, including observations, projections, impacts, risks, and solutions. This effort aims to sustain the momentum of the sixth National Climate Assessment (NCA), the authors and staff of which were dismissed earlier this week by the Trump Administration, almost a year into the process. Congressionally mandated, the NCA draws on the latest scientific research to evaluate how climate change is affecting the United States. The new special collection does not replace the NCA but instead creates a mechanism for this import...

Excerpt: The effects of human-caused climate change are already far-reaching and worsening across every region of the United States. Rapidly reducing greenhouse gas emissions can limit future warming and associated increases in many risks. Across the country, efforts to adapt to climate change and reduce emissions have expanded since 2018, and US emissions have fallen since peaking in 2007. However, without deeper cuts in global net greenhouse gas emissions and accelerated adaptation efforts, severe climate risks to the United States will continue to grow. ...In addition to reducing risks to future generations, rapid emissions cuts are expected to have immediate health and economic benefits (Figure  1.1 ). At the national scale, the benefits of deep emissions cuts for current and future generations are expected to far outweigh the costs. { 2.1 ,  2.3 ,  13.3 ,  14.5 ,  1...

The satellite fleets also mark a revival for NASA’s earth science, which has languished over the past decade compared with exploration of Mars and other planets....

The Trump team is preparing to appoint a climate denier to head development of the National Climate Assessment for the next two months, …. On Friday, the administration quietly removed Michael Kuperberg from his job as executive director of the U.S. Global Change Research Program (GCRP), …. Meanwhile, planning has been underway for weeks to appoint the National Oceanic and Atmospheric Administration’s David Legates, a climate change denier recently named as deputy assistant Commerce secretary…. Legates is a geologist from the University of Delaware and an affiliate of the Heartland Institute, which exists to muddy the public’s understanding of climate change. He has said burning more fossil fuels would benefi...
