A new United Nations climate report was released Monday morning explicitly describes how climate change has already affected the earth, warning that any warming will only aggravate the catastrophic catastrophe.
“There is no doubt that human influence has warmed the atmosphere, the sea and the land,” according to a summary of the findings of the report. “Human-induced climate change has already affected climate and climate change in all parts of the world.”
The most anticipated report is part of sixth weather analysis published by the UN Intergovernmental Panel on Climate Change, which provides a comprehensive scientific picture of the current climate crisis and a review of its potential effects.
The most recent report differs from previous translations by clearly identifying the root cause of climate change: human pollution due to climate change. With no restrictions on emissions from carbon dioxide, methane, and greenhouse gases, the report warned of high tide, heavy rainfall, droughts, and other catastrophes.
Hundreds of scientists from around the world have contributed to this report, along with their findings, which are summarized in a summary. Additional reports will be released in the next year and a half: The second report will determine who is most at risk of climate change and how best to prepare, while the third report will look at how to avoid extreme temperatures.
The announcement that human activity is the reason “the strongest statement made by the IPCC,” Ko Barrett, deputy chairman of the IPCC and senior climate adviser at the US National Oceanic and Atmospheric Administration, told reporters on Sunday.
The results of this new report could add to the problems that world leaders will face in Glasgow in November as part of their part of the Paris climate agreement.
If the world’s nations come together to cut their greenhouse gases by 2050 – the stated goal of the Paris climate agreement – global warming and other climate problems could be delayed and reversed, according to the report.
Taking action now could ensure that “the next 20 years of global warming may be our last resort,” Kim Cobb, co-author and climate professor at Georgia Tech, told reporters. “This is very important for me to remember here.”
Summer has been a long-term consequence of disasters. A history-breaking heat waves he killed hundreds in the Pacific Northwest and Canada. Flooding in Germany killed more than 100 people and hundreds more were missing. Thousands were displaced flooding in China. In the meantime, a raging fire that continues is running around the world, from California to Greece to Siberia.
Disasters are rampant, one of the ways in which the IPCC report states that the world has changed as a result of climate change:
Global warming so far it has risen by about 1.1 degrees Celsius since pre-industrial times. Such global warming has not occurred in less than 2,000 years.
Hot waves and the incidence of rainfall is very high throughout the world.
Drought it’s getting worse.
The surface of the oceans has been heated, the acidity of the oceans has increased, and the Arctic ice sheet has receded.
Hot water waves have almost doubled since the 1980’s.
All around the world the seas have already risen about half a foot, and the sea level rises sharply, due to the melting glaciers and rising sea levels. The rate of rising sea levels since the 20th century is the fastest at least 3,000 years.
And at the same time depletion of ice the world has never happened in the last 2,000 years of Earth’s history.
And the closest thing if people do not stop emitting greenhouse gases into the atmosphere is even worse.
A summary report states: “As the rise in global warming increases, extreme trends continue. Extreme heat, such as global warming, which occurred once every 10 years without any man-made climate change, now occurs at about 2.8 years.
And if the world continues to heat up, then fatal incidents it will be very possible. With temperatures of 1.5 degrees Celsius, extreme temperatures and other events can occur 4.1 times over a decade, according to the report, while 2 degrees Celsius can increase frequently to 5.6 degrees. The most dangerous event, a temperature of 4 degrees, is associated with extreme heat that occurs almost every year.
And not just heat. At any temperature of 0.5 degrees Celsius, the IPCC report warns that there will be an expected increase in heavy rainfall, as well as agricultural and environmental drought. Increased heat also brings increased risk of simultaneous disasters, such as heat waves and drought that occur simultaneously.
But no matter how bad the situation may be, the report emphasizes that reacting quickly and aggressively to climate change could also change some of the consequences. Rapid attempts to stop emissions and to release them into the atmosphere, releasing carbon dioxide, can promote changes in surface temperature and acidity at sea level.
Unfortunately, not all weather problems can be stopped. For example, rising sea levels around the world are now inevitable. “The transformation of the oceans in the mid-2050s, has not been stopped,” said co-author Bob Kopp. “Regardless of how much we reduce our emissions, we look at about 15 to 30 inches, or 6 to 12 inches, rising in water around the world.”
Furthermore, he added, “the comparison of sea water is strongly influenced by the choices we make today.” At a temperature of 2 degrees below sea level, the sea level will rise to about 1.5 feet[2100 m]; below 4 degrees, water can rise more than 2 feet within a century.
“It’s possible to deal with a lot of challenges, but there needs to be a change that hasn’t happened before,” Barrett said. “The idea that there is a way forward, I think, is a point that should give us hope.”
