The Obama administration will release an updated report today showing how climate change touches every part of the country, as the administration seeks to convince the American public on the need for a crackdown on carbon pollution.
Some environmental and public health groups expect the U.S. National Climate Assessment to be a "game changer" in the administration's efforts to address climate change.
The extensive report will update a January 2013 draft, which detailed how consequences of climate change are hitting on several fronts, including health, infrastructure, water supply, agriculture and especially more frequent severe weather.
Since then, the report was reviewed by the National Academies of Sciences and attracted more than 4,000 public comments.
The advisory committee behind the report was established by the U.S. Department of Commerce to integrate federal research on environmental change and its implications for society. It made two earlier assessments, in 2000 and 2009.
Thirteen departments and agencies, from the Agriculture Department to NASA, are part of the committee, which also includes academics, businesses, non-profit organizations and others. More than 240 scientists contributed to the report.
Among the key findings in the draft report expected to be reiterated are that the past decade was the country's warmest on record, and that some extreme weather events, such as prolonged droughts and heavier downpours, have increased.
Extreme weather events and other impacts of climate change also increase the risk of disease transmission and even mental health problems, the 2013 draft said.
Also expected to be featured is an ongoing sea-level rise, which increases the risk of erosion and storm surge damage and raises the stakes for the nearly 5 million Americans who live within four feet of the local high-tide level.
The report is expected to be posted in the Federal Register at 8 a.m. ET Tuesday.
