In recent years, thousands of Americans have died during, or as a effect of, extreme weather tied to climate change-from powerful hurricanes fueled by extremely warm seas to calamitous conflagrations stemming from drought.
The tragic Camp Fire in California serves as a stark illustration of how climate change is loading the dice for more extreme events that devastate people, homes and the economy.
"We are seeing the things we said would be happening, happen now in real life", said report co-author Katharine Hayhoe of Texas Tech University.
The report had originally been scheduled for release in December, but the National Oceanic and Atmospheric Administration announced on Wednesday that it would be released Friday.
Environmentalists said the assessment provides a mountain of evidence that climate change is not a political debate but an existential threat that warrants action to cut planet-warming pollution, before it's too late.
Friday's report seemed to anticipate such comments, saying: "Over shorter timescales and smaller geographic regions, the influence of natural variability can be larger than the influence of human activity ... The awful Camp Fire in California, the devastation caused by Hurricanes Florence and Michael... these events show us what is at stake", said EESI Executive Director Carol Werner.
Although climate change is expected to affect the country as a whole, there are a few communities who will feel the effects the most, the report said, including people who are already living in low-income and marginalized communities.
Climate change is expected to cause growing losses to American infrastructure and property and impede the rate of economic growth, according to a major new study.
Nevertheless, such a best case-scenario will still leave Americans in a country where they are paying tens of billions of dollar more annually to address the fallout of accelerating climate change.
But the report doesn't just make projections about changes that may occur decades from now; it attributes trends and disasters that we're already seeing today to climate change as well.
Climate change is already causing more frequent and severe weather across the USA, and the country is poised to suffer massive damage to infrastructure, ecosystems, health and the economy if global warming is allowed to continue, according to the most comprehensive federal climate report to date. And sadly, the most vulnerable among us - such as our youth and our elderly - are most likely to be affected by climate change given their disproportionate vulnerability to, for example, extreme heat events that are becoming increasingly common.
All of these changes, and the many others projected - including more severe storms, changes in growing seasons, and impacts on infrastructure - could majorly hurt the economy.
"The United States leads the world in providing affordable, abundant, and secure energy to our citizens, while also leading the world in reducing carbon dioxide (CO2) emissions", White House Deputy Press Secretary Lindsay Walters told ABC News in response to the study.
Some 30,000 people, including scientists, politicians, diplomats and businessmen from 200 countries are expected to take part in the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change, according to IAR news agency. "That means we have to focus on us", he said.
But at the same time predictions of future damage can change if drastically limit greenhouse gas emissions. Not surprisingly, this prompted suspicion that Trump's administration manipulated the timing of the report's release in an effort to mute its findings.
