When people say the wildfires, hurricanes and heat waves they're experiencing are unlike anything they've seen before, there's a reason for that, and it's called climate change.
This report supplements a study past year which found humans are the main driver of global warming and issues a stark warning of the impact if changes are not made.
The document's release was important in tackling a misconception by Americans that the changing climate doesn't harm them personally, instead "showing how climate change is already affecting each one of us, whether we live in Texas or Minnesota or Hawai'i or Florida", said Hayhoe, the Texas Tech climate scientist.
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.
"While President Trump continues to ignore the threat of climate change, his own administration is sounding the alarm", said Abigail Dillen, president of environmental group Earthjustice.
The report found it's not changing back any time soon - and said the country has to be prepared.
A comprehensive, transparent, peer-reviewed examination of the risks and impacts of climate change throughout the United States, the National Climate Assessment report to the President and Congress is required every four years by the Global Change Research Act of 1990 . "The bad 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.
He continued: "It's really, frankly, quite shameful for a president who just came out to California and visited the devastation in Paradise, California, in Malibu, where towns have literally been just wiped off the map as a result of the extreme weather we're seeing from climate change".
The report also noted that the change in climate has caused extreme weather along with changes in average climate conditions and that "future climate change is expected to further disrupt many areas of life, exacerbating existing challenges to prosperity".
Union stages protest on Black Friday over 'inhuman' working conditions at Amazon
Protesters are demonstrating outside Peterborough's Amazon fulfilment centre today to highlight concerns about working conditions. But Amazon said its European fulfillment network is fully operational and reports to the contrary are "simply wrong".
And in what might be the only angle that might appeal to Trump, it outlines how the issue could cost the economy billions of dollars, perhaps more than 10% of the GDP by the end of the century.
For the most part, they demurred, saying that in part the report was finished early and that they wanted to make sure it was out ahead of both an American Geophysical Union gathering next month, as well as a major worldwide climate conference in Poland around the same time.
This news outlet has been - and remains - skeptical of climate change theory.
"Actions to plan for and adapt to more frequent, widespread, and severe coastal flooding, such as shoreline protection and conservation of coastal ecosystems, would decrease direct losses and cascading impacts on other sectors and parts of the country", the study says.
Climate change is already causing more frequent and severe weather across the US, 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.
"The changing climate of the Northeast threatens the health and well-being of residents through environmental changes that lead to health-related impacts and costs, including additional deaths, emergency-room visits and hospitalizations, higher risk of infectious diseases, lower quality of life, and increased costs associated with health-care utilization", the report says.
There was no immediate comment on the report from the White House.
"If you look at the whole US, the amount of precipitation overall may be less, but it's delivered in these very intense precipitation events", explains Brenda Ekwurzel, an author of the report and senior climate scientist at the Union of Concerned Scientists.
But despite these ominous predictions, Light said the report gives us reasons for hope as well. The report's findings, while representative of a broad scientific consensus, run counter to Trump's agenda.
