Scientists See Climate Impacts Intensifying Faster Than Expected

Climate warning signs

Scientists studying global warming are wrestling with a consequential question: Is climate change accelerating?

That debate intensified after new research found that the rate of global warming has nearly doubled over the last decade. The findings drew intense attention in scientific circles, and not all researchers agree with that conclusion.

Even as that debate remains unsettled, a growing number of scientists agree on another troubling point: the effects of climate change are intensifying in ways that have surprised even experts.

Impacts outpacing expectations

Many consequences of global warming, including more intense storms, warming oceans and melting glaciers, are arriving faster and more forcefully than many scientists had expected.

Michael Mann, a professor of environmental science at the University of Pennsylvania, said that key impacts are exceeding what models predicted when it comes to extreme weather, hurricane intensification, ice sheet disintegration and sea level rise.

According to scientists cited in the article, several of Earth’s systems are changing faster than predicted as global temperatures rise.

The warning signs were reflected in recent weather across the United States. Parts of California and the Southwest saw temperatures rise above 100 degrees Fahrenheit even though it was still winter.

Recent research has also found that the duration and intensity of heat waves is accelerating. At the same time, blizzard conditions swept across the upper Midwest, while severe thunderstorms moved east from Arkansas to the Gulf.

Together, those developments have added urgency to the scientific debate over whether climate change itself is accelerating, even as researchers continue to disagree on that central question.
