Growing Effects of Climate Change
The United Nations Intergovernmental Panel on Climate Change (IPCC) also found that human-induced climate change is causing dangerous and widespread disruption of nature and affecting the lives of billions of people around the world. The panel said in its report this year that extreme weather events have caused severe food and water insecurity for millions of people, especially in Africa, Asia, Central and South America, small islands and the Arctic.
in Greenland and the Antarctic Melting ice can show the sight of cataclysm on this earth in the next few decades. The severe floods in Pakistan and the severe drought in China are just a small tableau of this. Even if there is no global warming, it will submerge the areas where millions of people live today. Now everything depends on what humans can do to stop the rising heat. According to the US space agency NASA, the Greenland ice sheet is the most important factor in the rise of oceans on Earth.
The heat in the arctic region is higher than in the rest of the earth It is growing more rapidly. In a new study published in ‘Nature Climate Change’, glaciologists have predicted that future fossil fuel pollution and rising heat will melt 3.3 percent of the volume of the Green Land ice sheet. As a result, the sea level will rise by 27.4 cm. This will change the map of the world. NASA scientists say that by the year 2100, three to four feet of water in the oceans could rise from the melting ice in Greenland alone. That much water would be enough to submerge many parts of the world. its This means that at present the model of rising sea level will be left behind. Even if the heat does not increase, there will be destruction.
These surprising results are also showing the least damage condition, as they do not account for the effect of future heat. According to lead author Jason Bax of the National Geological Survey of Denmark and Greenland, the climate around Greenland will continue to warm. Today, the reason for increasing the intensity and frequency of floods, droughts, forest fires, storms in tropical areas, etc. There is an increasing amount of greenhouse gases in the atmosphere coming out of forests and fossil fuels. There is no doubt that heat wave is also a direct effect of global warming.
After record heat in the coldest countries of Europe, China is also going through a period of unprecedented heat and drought. These days, there is a huge crisis of drought in India and its surrounding countries due to heavy rains and less rainfall. Pakistan is in the grip of severe floods. This year, amidst the scorching heat and heat wave in North India, there is a possibility of severe heat in Europe.
The news came China is facing the problem of severe heat this year. It is being told that this year China has experienced the worst heat in sixty-one years. In view of the rapidly rising temperature, people have been advised to stay in their homes. Due to lack of rain there has been a severe drought in many areas. The longest Yangtze River, known as China’s lifeline, has almost dried up. Regarding the increasing impact of climate change, experts are of the opinion that heat wave has become a direct and clear measure of global warming.
United Nations climate The Intergovernmental Panel on Climate Change (IPCC) also found that human-induced climate change is causing dangerous and widespread disruption of nature and affecting the lives of billions of people around the world. The panel said in its report this year that extreme weather events have caused severe food and water insecurity for millions of people, especially in Africa, Asia, Central and South America, small islands and the Arctic. 3.6 billion people are vulnerable to climate change.
The report added to its warning saying That the world faces several inevitable climate threats with a global warming of 1.5°C over the next two decades states that some of the consequences of this rising temperature will be irreversible. Increased heat waves, droughts and floods already exceed the tolerance limits of plants and animals, leading to large-scale mortality in species such as trees and coral. This has underscored the insecurity of food and water for millions of people, especially in Africa, Asia, Central and South America, small islands and the Arctic.
The IPCC report urged that “adapting to climate change requires prompt action, as well as rapid, profound reductions in greenhouse gas emissions.” There is a serious warning about the consequences of inaction. It shows that climate change is a serious and growing threat to our well-being and a healthier planet. Our actions today will determine how people live and how nature responds to rising climate risks. It has been estimated in the report published in ‘Nature Climate Change’ that the rise of sea level can go up to seventy eight centimeters.
In such a situation, a large part of the low-lying areas around the coast will be submerged, as well as floods and storms will increase. Instead of computer models, Bax and his colleagues used two decades of measurements and observational data to try to figure out how much the Greenland ice sheet would change based on the amount of heat it had previously experienced. The upper part of the ice sheet gets snowfall every year. It has to be filled. However, since the 1980s, the region has been suffering from a lack of snow.
More snow melts than the amount of snow received every year. Box says the theory the researchers used was designed to explain changes in the glaciers of the Alps. It is clear from this that if more ice accumulates on the glacier, then the lower part will expand. In the case of Greenland, the lower part is shrinking due to reduced ice, as glaciers adjust themselves to new conditions.do balance. Another IPCC expert, Gerhard Kriner, says the information found is in line with the overall information about sea level from more complex models. However, they do raise questions on whether all this will happen in this century.
According to Kriner, this work gives us an estimate of the long-term impact on the Greenland ice sheet, ie several centuries, but not the least impact of this century. The world averaged 1.2 degree Celsius hot. As a result, the series of heat wave and more strong thunderstorms has increased. Under the Paris climate agreement, the countries of the world have agreed to limit the heat to 2 degrees Celsius. The IPCC, in its report, has said about the effect of increasing heat on the climate that if the increase in heat is limited to two to two and a half degrees, then in this century, the low-lying areas of twenty-five megacities will be affected by it. As of 2010, 1.3 billion people lived in these places.
