National Oceanic and Atmospheric Administration Experts say that sea ice is melting, heavy rainfall is intensifying and heat waves are more common, among other indicators.
The past decade was the hottest ever recorded, part of an unequivocal pattern of warming dating back 50 years, a National Oceanic and Atmospheric Administration report declared on Wednesday.
The annual “State of the Climate” report drew on the findings more than 300 climate scientists in 48 countries who measured 10 separate planet-wide features, including air temperatures, sea temperatures, humidity, Arctic sea ice, glaciers and spring snow cover in the Northern hemisphere.
“The records come from many institutions worldwide,” Dr. Jane Lubchenco, the agency’s administrator, said in a statement. “They use data collected from diverse sources, including satellites, weather balloons, weather stations, ships, buoys and field surveys.
“These independently produced lines of evidence all point to the same conclusion: our planet is warming,” she said.
The findings do not include data from 2010, which is on pace to exceed the highest annual average global temperature ever recorded, NOAA said. This summer has been marked by extreme heat events in the eastern United States Europe, Russia, China, Japan and the Middle East. Read more…
