2014 On Track for Hottest Year on Record, U.N. Weather Agency Says
2014 On Track for Hottest Year on Record, U.N. Weather Agency Says
Jan 17, 2024 3:36 PM

The U.N. weather agency dismissed claims global warming has paused on Wednesday, after temperature data revealed 2014 was tied for hottest year on record.

In January-October of 2014, the global average temperature was 1.03 Fahrenheit above average, the World Meteorological Organization reported. The same record hot was recorded in 2010.

During this same period, a new record ocean temperature was set. Since the beginnings of recordkeeping in the 19th century, 2014 land temperatures were the fourth or fifth highest, the WMO noted. The WMO revealed this information in a report released at U.N. climate talks in Lima and at its Geneva headquarters.

"The provisional information for 2014 means that 14 of the 15 warmest years on record have all occurred in the 21st century," WMO Secretary-General Michel Jarraud said in a statement. "There is no standstill in global warming."

Climate skeptics point to a perceived hiatus in the temperature rise since 1998, an exceptionally hot year, to support their claims that man-made warming is not a big problem. Most climate scientists reject that idea. Michael Oppenheimer of Princeton University said the long-term warming trend is combined with natural variations that tend to be cyclical, with a period of lower-than-average warming followed by a period of rapid warming.

"Whether such a period is about to begin, we cannot say but the warm 2014 is a reminder that the warming never stopped and the long term trend is up, up, up," Oppenheimer said.

Parts of the planet were cooler than average, including large areas of the U.S., Canada and central Russia. But most of the world experienced temperatures above average, with heat waves in South Africa, Australia and Argentina in January and in large parts of South America in October, according to the WMO assessment, which was based on two global data sets from the U.S. and one from Europe.

Ocean temperatures were particularly high in the northern hemisphere from June to October.

"Around 93 percent of the excess energy trapped in the atmosphere by greenhouse gases from fossil fuels and other human activities ends up in the oceans. Therefore, the heat content of the oceans is key to understanding the climate system," the WMO said.

While scientists are now 95 percent certain that the temperature rise since the middle of the 20th century is mostly man-made, they can't say with the same confidence how the warming affects different parts of the climate system, including the frequency of tropical storms or hurricanes.

By Nov. 13 there had been 72 tropical storms, well below the average of 89.

Arctic sea ice shrunk to the sixth lowest level on record in September, while Antarctic sea ice grew to a record extent for the third straight year.

The concentration in the atmosphere of carbon dioxide, a key greenhouse gas, rose to a new high of 396 parts per million last year, the WMO said, 42 percent above the level before the industrial revolution, when people started burning fossil fuels for energy.

Figures for 2014 were not yet ready.

In Lima, delegates from more than 190 countries are trying to lay the groundwork for a global emissions pact that's planned to be adopted next year. Divisions between rich and poor countries have slowed the negotiations over the years, but a U.S.-China emissions deal last month has injected new hope into the talks.

U.N. climate chief Christiana Figueres said temperature data added urgency to the talks, but noted that you don't have to be a scientist to realize that the climate is changing.

"Every single one of us can just look out the window, open the door and see the effects of climate change," she said. "Because there is not one country that is exempt."
