How climate change will affect YOUR state: Leaked report reveals which regions will get hotter and wetter - and some are already feeling the effects
- Report found average temp across US is 1.18 degrees warmer than 1901-1960
- Daytime highs have climbed to 1 degree warmer, nighttime lows 1.35 degrees
- If CO2 pollution continues, temps will rise another 4.83 degrees by mid-century
A draft federal science report on the effects of global warming breaks down how climate change has already hit different regions of the United States.
It also projects expected changes by region.
Overall, the report found the annual average temperature across the 48 contiguous states is already 1.18 degrees warmer the last 30 years than it was from 1901 to 1960.
Daytime highs have climbed to 1 degree warmer and nighttime lows 1.35 degrees higher.

The draft also warns that, if carbon pollution continues unabated, temperatures are projected to rise another 4.83 degrees by mid-century.
By the end of the century, temperatures could rise by 8.72 degrees, or a few degrees less if emissions are cut somewhat.
NORTHEAST
(Maine, Vermont, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, West Virginia and Washington, D.C.)
-The annual average temperature, which has already risen about 1.37 degrees since 1901-1960, is expected to go up another 5.09 degrees by mid-century and 9.11 degrees by the end of the century if carbon pollution continues unabated.
If emissions are somewhat controlled, temperatures would go up another 3.98 degrees by mid-century and 5.27 degrees by late century.
-Extreme precipitation - rain and snow - has already gone up 17 percent compared with the first half of the 20th century and is projected to go up another 22 percent by the end of the 21st century if carbon pollution continues unabated.
If carbon dioxide emissions are somewhat reduced, it would only go up 14 percent.
-The northeast heat wave of July 2012 was made worse because of man-made climate change.
SOUTHEAST
(Virginia, Kentucky, North Carolina, South Carolina, Tennessee, Arkansas, Louisiana, Mississippi, Alabama, Georgia and Florida)
-The annual average temperature has only gone up about 0.4 degrees since 1901-1960, the lowest of any region in the nation.
It is projected to rise another 4.3 degrees by mid-century and 7.72 degrees by the end of century, if carbon pollution continues unabated.
If carbon emissions are somewhat reduced, the annual temperature would rise another 3.4 degrees by mid-century and 4.43 degrees by late century.
-Extreme rain has already increased by 8 percent compared with the first half of the 20th century and is projected to go up another 21 percent by the end of the 21st century if carbon pollution continues unabated.
If carbon pollution is somewhat reduced, it would only go up 13 percent.
MIDWEST
(Minnesota, Michigan, Wisconsin, Ohio, Indiana, Illinois, Iowa and Missouri)
-The annual average temperature has already gone up 1.18 degrees since 1901-1960 and is projected to rise another 5.29 degrees by mid-century and 9.49 degrees by the end of the century, if carbon pollution continues unabated.
If carbon emissions are somewhat reduced, the annual temperature would go up by 4.21 degrees by mid-century and 5.57 degrees by late century.
-Extreme rainfall has already jumped 9 percent compared with the first half of the 20th century and is projected to go up another 20 percent by the end of the 20th century if carbon pollution continues unabated.
If carbon pollution is somewhat reduced it would only increase 11 percent.
-An extremely wet spring in 2013 and a March 2012 heat wave were found to be connected to man-made climate change.
GREAT PLAINS NORTH
(North Dakota, South Dakota, Nebraska, Wyoming and Montana)
-The annual average temperature has already gone up 1.62 degrees - the most of any region - since 1901-1960.
It is projected to rise another 5.1 degrees by mid-century and 9.37 degrees by the end of the century, if carbon pollution continues unabated.
CLIMATE CHANGE ALREADY AFFECTING THE US, LEAKED REPORT SAYS
A federal climate report says the United States is already feeling the effects of climate change, with temperatures rising dramatically over the last four decades.
The report, by scientists from 13 federal agencies, says extreme heat waves have become more common and extreme cold waves less common since the 1980s.
Average US temperatures have risen dramatically and fast, with recent decades the warmest of the past 1,500 years.
It also says emissions of greenhouse gases will affect the degree to which global temperatures continue to rise.
The Paris accord commits signatories to efforts to reduce greenhouse gas emissions that cause global warming. This graphic shows Nasa / NOAA data that found 2016 was the warmest year globally on record
This is a claim President Donald Trump and some members of his cabinet have disputed the New York Times, which acquired a draft copy of the report, said.
'Americans are feeling the effects of climate change right now,' said the report which has not yet been released or approved by President Donald Trump's administration.
'How much more the climate will change depends on future emissions and the sensitivity of the climate system to those emissions.'
The draft report, part of the United States National Climate Assessment, is done every four years. It has been signed by the National Academy of Sciences.
If carbon emissions are somewhat reduced, the annual temperature would go up by 4.05 degrees by mid-century and 5.44 degrees by late century.
-Extreme rainfall has already gone up 6 percent since the first half of the 20th century and is projected to go up another 16 percent by late century, if carbon pollution continues unabated.
If carbon emissions are somewhat reduced it would be 10 percent.

HAWAII
-The average annual temperature in Hawaii has gone up 0.75 degrees since 1925-1960.
-The extremely active 2014 Hawaiian hurricane season has been connected to man-made climate change.
