UN Weather Report: All Is Not Well – But All Is Not Lost

Today United Nations’ Intergovernmental Panel on Climate Change has been released a new shocking report on the weather: 14,000 pieces of science fiction produced by hundreds of scientists. It is a complete announcement of what scientists know about humanity’s global warming: global warming, melting glaciers, droughts and hurricanes, and the process worsening the future – unless we act quickly and decisively to reduce emissions.

“We have known for years that the earth is warming, but this report tells us that climate change is recent, widespread, and increasing – something that has not happened for thousands of years,” said Ko Barrett, vice chairman of IPCC and senior climate adviser at National Oceanic and Atmospheric. Administration, at a press conference on Sunday to announce the report. “Obviously, unless a rapid, rapid, and significant reduction in greenhouse gas prices, a reduction of 1.5 degrees C – or 2.7 degrees Fahrenheit – is not possible.”

That limit is a sure hope for Paris Climate Alliance: global temperature up to 1.5 degrees Celsius above pre-industrial, as well as to avoid two degrees Celsius. The new report says the temperature has already risen to 1.1 degrees, and is up to 1.5 times earlier – by mid-2030 if things do not change.

It is a major change from the previous IPCC report predicting a global peak of 1.5 by 2040, said Zeke Hausfather, a climate scientist and director of climate and energy at the Breakthrough Institute, who did not participate in the report. “Similarly, we are going through two degrees somewhere in the early 2040s and early 2050s as a preview of what can happen,” he says, referring to one of the five outcomes cited in the new report.

Why is half a degree so important? “There is a significant difference between 1.5 and 2,” depending on the size of drought, warm waves, storm, flooding, they did not melt, and sea ​​level rise, said Janos Pasztor, director-general of the Carnegie Climate Governance Initiative and former UN secretary-general on climate change, who did not participate in the report. “Two are growing up. And more than 2 receive more, more bad. And there is the possibility, of course, that we will come this way. ”

The report outlines the possible effects of five different greenhouse gas emissions: This takes into account the future of human-induced emissions, from very low to very low. (At very low levels, gas levels drop to zero zero around 2050 and continue to fall. At the top, they double that year.) In other words, I predict what the weather will look like based on the speed at which our development decarbonizes.

The accompanying diagrams also show the potential global warming and rainfall patterns, as well as the number of regions in the world that have experienced extreme heat, rain, and drought. (Clue: Almost all of them.)
