The fears being raised about climate change are beginning to come true. In the last six months only, the mood of the weather witnessed in the world has turned the minds of environmental scientists. Extreme weather events have started showing their harsh nature. Be it summer or rain or floods. Much more than usual has started happening in many places. Environmental scientists, based on the analysis of data of the last 20 years, have tried to tell how this crisis has started creating upheaval in our lives.
Changing weather patterns
The whole world has seen many unexpected weather events so far this year. Somewhere there has been a terrible heatwave, and somewhere unusual rains have caused havoc. Due to such harsh weather conditions, thousands of lives have been lost on earth this year and many lakhs have been forced to leave their homes and become homeless. According to a report by Reuters, in the last three months, the heavy rains have wreaked havoc in Bangladesh, while many parts of South Africa and Europe heat up. Talking about India, Assam is still facing the devastation of floods. At the same time, millions of people in East Africa are facing famine due to prolonged drought. On this cruelty of weather, scientists say that this all is happening because of climate change.
What did the scientists find in the research?
On Tuesday, a team of environmental scientists published research in the journal Environmental Research: Climate. The research paper titled ‘Extreme weather impacts of climate change: an attribution perspective’. To see how climate change has changed the weather, researchers have examined weather events over the past two decades. Its result has confirmed this and has also given a warning about how global warming will change our world.
Luke Harrington, a climate scientist at Victoria University in Wellington, and co-author of this study said about heatwaves and extreme rainfall, 'We found that we have a better understanding of how the intensity of these events is changing due to climate change. 'However, there is still more understanding to be developed about how climate change affects wildfires and droughts.
Worsening heatwaves
As far as the heatwaves are concerned, it has been found in research that it is very likely that the situation is getting dire due to climate change. "Almost all heatwaves around the world have been made more intense and more likely by climate change," said Ben Clarke, an environmental scientist at Oxford University and a co-author of the research. In general, if the probability of a heatwave was 1 in 10 before, it is now three. Not only this, compared to without climate change, the temperature is about 1 °C. According to the World Weather Attribution (WWA), for example, if the mercury in India and Pakistan went above 50 degrees during the heatwave in April, there is a 30 times chance that it was due to climate change. Similarly, the heatwave seen in Europe and America in June is also very high.
Extreme rains and floods
Last week China witnessed catastrophic flooding after heavy rains. At the same time, a deluge situation arose in Bangladesh as well and Assam is still in the grip of floods. Overall, heavy rain events have become normal and have started happening frequently. This is because the warm air absorbs more moisture, due to which the storm clouds become heavy and then fall as rain. But, even then it is not the same everywhere. There is devastation in many places and in some places, there is a lack of rain.
Drought and wildfires disrupting balance of ecosystem
Scientists have had a hard time figuring out how drought affects climate change. Some areas are still in the grip of drought. According to research, warmer temperatures in the western US are causing ice to melt faster, leading to more evaporation. However, the drought in East Africa has still not been directly linked to climate change. Scientists say that the decrease in rainfall in the spring here is associated with warm water in the Indian Ocean. Due to this, before the clouds reach there, it rains in the sea itself.
The rise in the incidence of wildfires Heatwaves and droughts are also increasing the incidence of forest fires, especially due to the increase in the incidence of large fires, in which more than 100,000 acres of land are burning. . In April, controlled burning of forests in an extremely dry climate in the US state of New Mexico went unchecked, and according to the US Forest Service, 3,41,000 acres of wildfires were reduced to ashes.
