Global Warming Is Speeding Up and the World Is Feeling the Effects

An anonymous reader shares a report: Summer started barely a week ago, and already the United States has been smothered in a record-breaking "heat dome." Alaska saw its first-ever heat advisory this month. And all of this comes on the heels of 2024, the hottest calendar year in recorded history. The world is getting hotter, faster. A report published last week found that human-caused global warming is now increasing by 0.27 degrees Celsius per decade. That rate was recorded at 0.2 degrees in the 1970s, and has been growing since. "Each additional fractional degree of warming brings about a relatively larger increase in atmospheric extremes, like extreme downpours and severe droughts and wildfires," said Daniel Swain, a climate scientist at the University of California. While this aligns with scientific predictions of how climate change can intensify such events, the increase in severity may feel sudden to people who experience them. "Back when we had lesser levels of warming, that relationship was a little bit less dramatic," Dr. Swain said. "There is growing evidence that the most extreme extremes probably will increase faster and to a greater extent than we used to think was the case," he added. Take rainfall, for example. Generally, extreme rainfall is intensifying at a rate of 7 percent with each degree Celsius of atmospheric warming. But recent studies indicate that so-called record-shattering events are increasing at double that rate, Dr. Swain said.
