The US region famous for its colonial history, maple syrup and bitterly cold, snow-bound winters is experiencing a swift change. Fresh analysis shows that New England is warming more quickly than almost anywhere else on the Earth.
The speed of warming in New England makes it the most rapidly warming region of the contiguous United States, according to the study. The rate of its warming has reportedly increased notably in the last half-decade.
"The temperature is not only rising, it's speeding up," said a primary researcher on the project. "It's really sped up in the past few years, which surprised me. Our regional climate is shifting in a different trajectory, after being relatively stable for millennia."
The research positions the New England region among the most rapidly heating zones in the world, alongside the polar region and parts of Europe and China. "The region is now moving toward being like the American South," the scientist added.
For the analysis, researchers analyzed three datasets on day and night temperatures and snowpack dating back to 1900. The analysis encompassed the six states of the New England region.
They discovered that New England has heated up by an average of 2.5°C (4.5°F) from 1900 to 2024. This is substantially higher than the global average, with the planet warming by approximately 1.3 degrees Celsius in the comparable timeframe.
"This represents extremely rapid heating, which is alarming," commented the study author.
A primary reason for this unusual accumulation of heat may be shifts in the North Atlantic. The world's oceans are taking in more than 90% of the surplus thermal energy trapped by emissions.
In the north Atlantic, an increase of cold, fresh water from Arctic ice melt is disrupting the Gulf Stream. This is directing warmer water into the Gulf of Maine, congregating heat along the coastline that is then carried further inland by wind patterns.
"Surplus thermal energy from climate change is being stored in the sea like a massive battery," explained the researcher. "This is now being discharged into the air and New England is a recipient of that energy."
Once considered a mild climate haven, New England has experienced severe climate events in the past decade, including devastating floods and prolonged dry spells.
The rising heat poses a threat to cherished aspects of regional life:
"I reside just north of Boston and when I arrived in the 1990s I used to ice skate on the ponds regularly," said the researcher. "That sort of thing has largely disappeared from much of southern New England."
