3 Degrees Celsius Global Warming Can Destroy The Planet

There are real opportunities the earth will experience a temperature of about 3 degrees Fahrenheit[54degreesFahrenheit)inthiscentury-andthatcouldbedangerous

In such a tropical climate, scientists admit that extreme heat, wildfires, and destructive rains will be more frequent and more severe than they are today. The sea will be very hot and very acidic, causing the fish to shrink and possibly the extinction of salt marshes. Instead, about a quarter of all life on earth it can end in such circumstances or guided in that way. Our beaches can be redesigned, with the effect of rising sea levels for hundreds of years, dry place such as Charleston, South Carolina’s Market Street, Providence, Rhode Island, and the Space Center in Houston.

All of this, as meteorologist Daniel Swain of the University of California, Los Angeles, puts it, would be bad: “Bad for people. Evil in nature. Evil on the stability of the Earth system on which we humans depend on everything. “

Experts cannot predict exactly what the future will hold because it depends on what people do to reduce climate stress, especially in the next decade. But for international leaders gathered this weekend in Glasgow for the 26th session of the United Nations Climate Change (COP26), the future could be inevitable if they did not adhere to harsh and simultaneous measures to reduce greenhouse gas emissions.

“Evil to the people. Evil to the environment. Evil to the stability of the Earth’s systems on which we humans depend on everything.”

The global goal under the Paris climate agreement is to prevent global warming by no more than 2 degrees Celsius (3.6 Fahrenheit), no more than 1.5 degrees (2.7 Fahrenheit) if necessary. But in the meantime, we are on our way almost double – 3 degrees which can be dangerous.

“I’m afraid that without science-based goals, and a goal to achieve, we would be facing a 3-degree-Celsius world by the end of this century,” said Kim Cobb, a climate scientist at Georgia Tech and one of the authors. a recent report by the Intergovernmental Panel on Climate Change (IPCC), told BuzzFeed News. “It’s impossible to imagine, to be honest.”

So, what would a temperature of 3 degrees Celsius look like?

First, our planet will be much warmer than it is today.

The waters of Lake Tahoe Lake have fallen to the bottom of the natural range, dropping more than 3 meters and blocking the flow of the Truckee River as seen in Oct. 17 in South Lake Tahoe, California.

In the beginning future temperature measurement is not today – it was in the late 19th century, when a reliable record of global warming began to emerge. More than 100 years later, the earth has already heated to over 100 degrees Fahrenheit[1 ° C](1.8 degrees Fahrenheit) due to the high levels of fossil fuels such as carbon dioxide and methane in the atmosphere. It’s average, but some areas are already getting very hot.

Adding another 2 degrees to more than 1 degree that we have already added could make our country the hottest and hottest on the planet. Here’s why: About 70 percent of the earth’s surface consists of water, and the water temperature rises more slowly than the surface of the earth.

Swain explained: “If the whole earth were to warm up to minus 3 degrees Fahrenheit[3 ° C]the whole earth must be much warmer.”

“It’s impossible to imagine, to be honest.”

This could be about 1.5 degrees Fahrenheit[1.5 degrees Celsius]or at a total of 4.5 degrees, according to Zeke Hausfather, a weather scientist and electrician at the Breakthrough Institute. And it will be very hot in the Arctic, where it already is heat about three times global standard.

One way to determine the degree to which this is most likely to occur is by considering the number of days the temperature in the region reaches or above 95 degrees Celsius (35 degrees Celsius). At the turn of the century, Arizona experienced about 116 days of such heat, Texas met with 43 days, Georgia 11 days, Montana about 6 days, and Massachusetts only one day, according to model by the Climate Impact Lab.

Had global temperatures plummeted to about 3 degrees Celsius by 2100, these figures would have risen from about 179 to 229 days at least 95 degrees Fahrenheit in Arizona, 135 to 186 days in Texas, 85 to 143 days in Georgia, 46 to 78 days in Montana, and 26 to 66 days in Massachusetts, at the same time.

Disasters will abound.

The sign gives a drive to the cooler location at Kellogg Middle School in Portland, Oregon, on Aug. 14.

This summer only, the heat of the Northwest Pacific led to Death Valley-like heat in British Columbia, Oregon, and Washington, killing hundreds of people in the circumstances that scientists agree would be “almost impossible”Without climate change. Then a a historic rain dropped about 9 inches in central Tennessee, killing about a dozen people. And last weekend, more than 5 inches down per day in the California capital of Sacramento, is setting a new record.

“My guess is, what could this surprise be in a tropical 3-degree world?” Swain said.

It is impossible to know exactly how he will answer. But its form of visibility is already evident: extreme heat and humidity as well as heavy rainfall and heavy rainfall, even in areas where it is expected to be very dry in such a country. This is true almost everywhere in the world.

“There are very few places on Earth that do not see an increase in rainfall,” Swain said, adding that “there are areas where there may be no zeros that will not increase on hot days.”

Warren Montgomery is trying to cross a road in Chadds Ford, Pennsylvania, following a historic flood from Hurricane Ida.

Statistics from a recent IPCC report support this. What was considered to be the event of one year’s maximum temperature in 10, such as global warming, in the late 1880s could be more than 5.6 times in the tropical world. The effect can be costly due to the explosion of air conditioners, which can lead to problems caused by electricity. Those who do not have a chance to catch a cold can get very hot. And then there is the issue of water scarcity; along with constant heat waves, they can cause serious damage to crops.

Similarly, what was once considered a year-long or 10-year-old hurricane may be more than 1.7 times greater. Such disasters have historically been a source of frustration for roads, flooded homes and businesses, and power cables.

In the meantime, local disasters will increase in frequency and intensity. Think of the long-term drought and wildfires on the West Coast and the strong winds in the Gulf Coast and the East Coast. Worse still, the so-called “catastrophic flood” may indicate that such events are happening one after another or at the same time. Lake Charles in Louisiana, which suffered a number of disasters announced by the government in one year: relapses, including Group 4 hurricanes, followed by a fifth hurricane and flood.

In a tropical world 3-degree, coastal areas today will be extinct, continuously declining for centuries to come as a result of rising sea levels.

By the end of the 2100’s, seawater is expected to rise to more than six feet[2 m]. This would be extremely dangerous for small island nations. Most of the Maldives, the mainland islands of Bermuda, as well as other Seychelles islands, including its own airport, can be submerged. Similarly, large parts of Thailand’s capital Bangkok, home to more than 5 million people; the cities of Amsterdam, The Hague, and Rotterdam in the Netherlands, which, together, have a population of about 2 million; and much of the U.S. Gulf Coast, including parts of major cities such as New Orleans and Texas Galveston. These examples are from making a map and the Climate Central research team, whose ideas do not take into account the recent or future security measures being taken to prevent rising water levels.

“Approximately 12% of the world’s population on land may be at risk.”

Water will continue to rise for the next hundred years and beyond. With that in mind for the next 2,000 years, Robert Kopp, a meteorologist at Rutgers University, expects the water to be somewhere between 13 feet and 30 feet above current levels. The surging waters, assuming there is no safety in the rising tide, could seize areas of California’s Bay Area and Los Angeles and rehabilitate large areas of Texas, Louisiana, Mississippi, Alabama, and Florida, according to Climate Central. making a map.

“It is estimated that approximately 12% of the population living on land may be at risk for long-term sea level rise below 3 degrees Celsius,” said Scott Kulp, chief computational scientist at Climate Central. “That’s 810 million people.”

The 2100’s equation does not take into account the potential for global glaciers to melt rapidly, and even long-term estimates do not necessarily predict a rapid collapse, although it is possible. “The more we push the machine above 2 degrees Celsius – but we do not know how many – the more we have the opportunity to develop ice caps that will increase sea levels,” Kopp said in an email.

The dangers are unknown.

Probably too much The scary thing about a tropical climate is the uncertainty of how it can affect the way our carbon dioxide is depleted – think of plants and trees, the soil, even the oceans – constantly and constantly absorb carbon dioxide from the atmosphere. . If any of these sinks were to stop absorbing too much oxygen, the air would be exposed to the atmosphere, causing global warming.

“We can’t stop the tropical climate of 4 degrees.”

Or it could be that one of the longest carbon sinks could ever be exhausted. Currently, for example, there is an iceberg, called permafrost, that spreads to all parts of the world, including trees. Together, all this permafrost saves a lot of carbon than it is in the atmosphere. As the planet heats up, the permafrost component melts, releasing more air into the atmosphere along the way and adding more heat to the hazardous solution system.

“Half of our air has now been recycled by natural carbon sinks that have been in operation for the past decade, over the next ten years,” said Cobb of Georgia Tech. “That is why in the future, as a climate scientist, it is very important that we begin to understand that there is a real risk that these natural sinks may stop working even at high temperatures.”

As the Hausfather of the Breakthrough Institute put it: “The fact is, even if we think we are on the verge of a tropical warming under modern technology, we certainly cannot prevent a warmer degree of 4 degrees.” ●
