The latest major report in 8 years from the UN’s Panel on Climate Change found the world has warmed 1.1°C higher than preindustrial levels. Now, the UN chief says the IPCC climate report is “code red for humanity.”
The report shows the world has warmed 1.1 degrees Celsius higher than preindustrial levels.
In a statement, UN Secretary-General António Guterres warned that the 1.5-degree threshold is “perilously close.” He called the findings “a code red for humanity.”
“The only way to prevent exceeding this threshold is by urgently stepping up our efforts, and pursuing the most ambitious path,” Guterres said.
Michael E. Mann, a lead author of the IPCC’s 2001 report, told CNN: “Bottom line is that we have zero years left to avoid dangerous climate change, because it’s here.”
According to the report, the world is on track to exceed 1.5°C by 2030 and reach +2° C warming between 2050-2060.
The report found the following key events:
– The past five years have been the warmest on record since 1850.
– The Global surface temperature was 1.09C higher in the 10-year period between 2011-2020 than between the 50-year period of 1850-1900.
-The rate of sea-level rise in recent years has nearly tripled compared with 1901-1971.
The report concluded that human influence was “very likely,” and rated it 90 percent likely that human activity the main cause behind the global retreat of glaciers since the 1990s and the decrease of sea-ice in the Arctic.
The report also concluded it was “virtually certain” that extreme hot weather and he waves have become both more intense and more frequent since the 1950s, while opposite events of extreme cold have become less severe and less frequent.
According to an IPCC chart, looking at “simulated natural factors only,” throughout history, the average global temperature stayed relatively the same.
But when considering observed human factors, things were relatively the same until 1925 when global temperature began to rise slightly and continued to climb until around 1950, when it took a slight dip, although remaining higher than preindustrial levels. But it began to climb again in the 1960s. And beginning in the 1970s, the global temperature began to rise significantly and has continued ever since. Most alarming, however, global temperatures have risen rapidly since 2000.
According to the study authors, since 1970, global surface temperatures have risen faster than they have in any other 50-year period over the past 2,000 years.
The IPCC report stated: “it is unequivocal that human influence has warmed the atmosphere, oceans and land.”
The study asserts that: This warming is “already affecting many weather and climate extremes in every region across the globe.”
“It is a statement of fact, we cannot be any more certain,” wrote Professor Ed Hawkins, one of the study authors. “It is unequivocal and indisputable that humans are warming the planet.”
