Global temperatures could exceed crucial 1.5 C target in the next five years

Ilulissat Icefjord, Greenland, July 30, 2029

In this aerial view melting ice forms a lake on free-floating ice jammed into the Ilulissat Icefjord during unseasonably warm weather on July 30, 2019 near Ilulissat, Greenland. In 2020, the Arctic is likely to have warmed by more than twice the global mean, a new assessment by the WMO found.

There is an increasing chance that annual global temperatures could exceed 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels over the next five years, new climate predictions from the World Meteorological Organization (WMO) say.

Under the 2015  Paris climate accord, countries committed to reduce their carbon output and halt global warming below 2 degrees Celsius — and if possible, below 1.5 degrees Celsius — by the end of the century to avoid the worst impacts of climate change.

But according to the WMO report, there is around a 20% chance that one of the next five years will be at least 1.5 degrees Celsius warmer than pre-industrial levels, with the chance “increasing with time.”

Annual global temperature is likely to be at least 1 degrees Celsius warmer than pre-industrial levels, and the last five years has been the warmest on record, the assessment — based on modeling and the expertise of climate scientists — found.

In 2020, the Arctic is likely to have warmed by more than twice the global mean, and many parts of South America, southern Africa and Australia are likely to be dryer than in the recent past, the WMO said.

There is a 70% chance that one or more months during the next five years will be at least 1.5 degrees Celsius warmer than pre-industrial levels, the WMO assessment said.

In the coming five years, almost all regions are likely to be warmer than the recent past, scientists warned.

Climate Feedback Article Review…

Article by Michael Shellenberger mixes accurate and inaccurate claims in support of a misleading and overly simplistic argumentation about climate change

2020 Climate Feedback Article Review 28

 

Analysis of “On Behalf Of Environmentalists, I Apologize For The Climate Scare”
Published in Forbes, by Michael Shellenberger on 28 June 2020

Six scientists analysed the article and estimate its overall scientific credibility to be ‘low’.

A majority of reviewers tagged the article as: Cherry-pickingMisleading.

Climate Feedback Claim Review…

Study evaluates natural and human causes of recent rapid warming rate at the South Pole 

CLAIM: Surface air temperatures at the bottom of the world have risen three times faster than the global average since the 1990s.

VERDICT: Accurate

SOURCE: Even the South Pole Is Warming, and Quickly, Scientists Say by Henry Fountain, Climate, New York Times, June 29, 2020

KEY TAKE AWAY: This statement accurately describes data analyzed in a recently published scientific study. As the article also explains, that study concluded that the temperature trend at this specific location was boosted by natural variability, and is not representative of the current human-caused climate change across Antarctica.
