The studies clash with policy under President Donald Trump, who has been rolling back Obama-era environmental and climate protections to maximize production of domestic fossil fuels, including crude oil, already the highest in the world, above Saudi Arabia and Russian Federation.
The study, called the National Climate Assessment, is the fourth in an ongoing series mandated by a 1990 law.
"With the Paris climate agreement in mind, we need to think about solving our problems in ways that are beneficial for our planet", Kurtyka said.
The researchers found that the average temperature in the U.S. rose 1.2 degrees Fahrenheit from 1951-2010, and an additional 2 degrees more is inevitable by 2050.
The report also finds that the USA will be 3-12 degrees hotter by the end of the century, depending on how much greenhouse gas is released into the atmosphere.
In Pennsylvania, aging bridges may not fare well against more extreme storms, and water and wastewater systems need nearly $30 billion in investment. About $1 trillion of wealth in coastal real estate could be threatened. Extreme weather directly causes both cold and heat-related deaths. "There is broad consensus that the further and the faster the Earth system is pushed towards warming, the greater the risk of unanticipated changes and impacts, some of which are potentially large and irreversible".
Climate change will wreak havoc on the natural environment, economy and public health in the United States unless more is done to drastically reduce carbon emissions, a USA government report has warned. It was a collaboration of 1,000 people, including 300 leading scientists, half of whom are from the government.
Andrew Light, a senior fellow at the World Resources Institute, worked on the chapter focusing on mitigation. "While Americans are responding in ways that can bolster resilience and improve livelihoods, neither global efforts to mitigate the causes of climate change nor regional efforts to adapt to the impacts now approach the scales needed to avoid substantial damages to the USA economy, environment, and human health and well-being over the coming decades".
"I can confirm it considers all scenarios, from those where we go carbon negative before end of century to those where carbon emissions continue to rise", Texas Tech University climate scientist Katharine Hayhoe responded on Twitter.

"A warm, dry climate has increased the areas burned over the last 20 years", he said at a press conference Friday. "Flooding from heavy rainfall, storm surge, and rising high tides is expected to compound existing issues with aging infrastructure in the Northeast".
Residences leveled by the Camp Fire line a cul-de-sac in Paradise, Calif., earlier this month.
Why publish this on Black Friday? Report director David Reidmiller said questions about the timing were "relevant", but said what was in the report was more important.
"Making an announcement on Friday is called taking out the trash. It's just been getting worse and worse and worse over that time", he said. "This administration does not want anyone to understand that this report is coming out".
"People are going to die if we don't start addressing climate change ASAP", she wrote. And that's a shame, because this should not be a partisan issue.
It warns of more, stronger and longer disasters triggered at least in part by global warming.
Rather, they implored reporters to focus instead on the contents of the report, which they said had not been tinkered with by administration officials.
"Rising air and water temperatures and more intense extreme events are expected to increase exposure to waterborne and foodborne diseases, affecting food and water safety", the report said.
