The U.S. and Canada will be hardest hit by global warming and other changes, a new report released Tuesday shows.

A report by the Congressional Research Service said the U.N. Intergovernmental Panel on Climate Change is forecasting temperatures of 1.8 to 3.4 degrees Celsius, which is the equivalent of two to three feet of global warming.

The report said the world will experience a 4.6 to 8.6 degrees Celsius rise, or about the same as the rise in sea levels from 2 feet to 6 feet, depending on the exact time of year.

While the U,S., and Canada are not among the countries that will be most impacted by the warming, it is expected the two nations will suffer the most, the report said.

It said Canada and the U will be “worse hit by the rise,” as temperatures will increase by 0.6-0.8 degrees Celsius.

The U.K., which is projected to be the hardest hit region by global climate change, will be the most vulnerable to the rise, it said.

It’s predicted to experience temperatures increase by 1.6 degree Celsius and be “more vulnerable to sea level rise,” the report added.

Despite the findings, it’s not clear whether the warming will actually be severe enough to trigger severe weather events.

The report says the world’s two largest cities, New York and London, will see increases in flooding and other flooding risks, especially in coastal cities.

The coastal cities will also see increases of 0.3 to 0.4 inches in sea level, which can make them vulnerable to erosion.
