‘Earth’s fever rises’: New report shows many symptoms of climate change

WASHINGTON – Earth’s fever got worse last year, breaking dozens of climate records, scientists said in a massive report nicknamed the annual physical for the planet.

Soon after 2015 ended, it was proclaimed the hottest on record . The new report shows the broad extent of other records and near-records on the planet’s climatic health. Those include record heat energy absorbed by the oceans and lowest groundwater storage levels globally, according to Tuesday’s report from the National Oceanic and Atmospheric Administration.

“I think the time to call the doctor was years ago,” NOAA climate monitoring chief Deke Arndt, co-editor of the report, said in an email. “We are awash in multiple symptoms.”

The 2015 State of the Climate report examined 50 different aspects of climate , including dramatic melting of Arctic sea ice and glaciers worldwide. A dozen different nations set hottest year records, including Russia and China. South Africa had the hottest temperature ever recorded in the month of October: 119.1 degrees Fahrenheit (48.4 degrees Celsius).

Even though it was a relatively quiet hurricane year in the Atlantic, there were 36 major tropical cyclones worldwide – 15 more than average, said NOAA climate scientist Jessica Blunden, co-editor of the report published Tuesday in the Bulletin of the American Meteorological Society.

And at the heart of the records is that all three major heat-trapping greenhouse gases – carbon dioxide, methane and nitrous oxide – hit record highs in 2015, Blunden said.

“There is really only one word for this parade of shattered climate records: grim,” said Georgia Tech climate scientist Kim Cobb, who wasn’t part of the report, but called it “exhaustive and thorough.”

But it’s more than just numbers on a graph. Scientists said the turbo-charged climate affected walrus and penguin populations and played a role in dangerous algae blooms, such as one off the Pacific Northwest coast. And there were brutal heat waves all over the world, with ones in Indian and Pakistan killing thousands of people. One-third of Earth’s land mass had some kind of drought last year.

Much of the intense record-breaking and record-flirting weather was because of a combination of a natural El Nino – the periodic warming of parts of the Pacific that changes weather globally – and ever increasing man-made global warming.

“This impacts people. This is real life,” Blunden said.

Oklahoma University meteorology professor Jason Furtado said in an email that the report, which he wasn’t part of, illustrates the combined power of nature and humans on Earth’s climate: “It was like injecting an already amped-up climate system with a dose of (natural) steroids.”

About 450 scientists from around the world helped write the report and in it NOAA highlighted one of the lesser-known measurements, ocean heat content. About 93 per cent of the heat energy trapped by greenhouse gases – such as carbon dioxide from the burning of coal, oil and gas – goes directly into the ocean, the report said. And ocean heat content hit record levels both near the surface and deep.

NOAA oceanographer Gregory C. Johnson, a study co-author, said the oceans are storing more heat energy because of man-made climate change with an extra El Nino spike.

Johnson summed up Earth’s climate in a haiku, published deep inside the report:

“El Nino waxes,

warm waters shoal, flow eastward,

Earth’s fever rises.”
