From killer heatwaves to floods, climate change may worsen weather extremes in 2021

New Delhi: Extreme weather events broke records around the world in 2021. Hurricanes and heatwaves killed hundreds, farmers grappled with drought, and in some cases with locust plagues. Wildfires set new records for carbon emissions and swallowed up forests, towns and homes. Many of these events were accelerated by climate change. Scientists say there is much more to come and even worse. Because the Earth’s atmosphere is getting warmer for the next decade and beyond. (Climate change)

Some of the events observed in the last one year (Climate change)

February – A severe cold in normally warm Texas has killed 125 people in the state and left millions without electricity in freezing temperatures. Scientists haven’t reached a conclusion whether climate change has caused extreme weather, but warming of the Arctic is causing more unpredictable weather around the world.

February – Kenya and other parts of East Africa battled some of the worst locust plagues in decades, with the insects destroying crops and pastures. Scientists say unusual weather patterns caused by climate change have created ideal conditions for the insects to thrive.

March – The skies over Beijing turned orange and flights were halted during the worst sandstorm over the Chinese capital in a decade. Busloads of volunteers arrive every year to plant trees in the desert, which can stabilize the soil and serve as a buffer to the wind. Scientists predict that climate change will worsen desertification, as hot summers and dry winters reduce moisture levels.

June – Almost the entire western United States was hit by the drought that struck in early 2020. Farmers abandoned crops, officials announced emergency measures. Hoover Dam reservoir reaches its lowest level ever. As of September, the U.S. The government confirmed that over the past 20 months, the Southwest received the lowest rainfall in a century, and linked the drought to climate change. (Climate change)

June – US And hundreds of people died during a record-smashing heatwave in the Canadian Pacific Northwest, which scientists concluded would be nearly impossible without climate change. For several days power lines were snapped and roads were uprooted. Cities battling the heat opened cooling centers for the safety of their residents. During the heatwave, Portland, Oregon hit an all-time record high of 116 Fahrenheit (46.7 Celsius).

July – Devastating floods killed more than 300 people in central China’s Henan province when a year’s worth of rain fell in just three days. Meanwhile, in Europe, about 200 people have died due to torrential rains in Germany, Belgium and the Netherlands. Scientists concluded that climate change made flooding more likely to occur.

July – A record heatwave and drought in the US West triggered two massive wildfires that ripped through California and Oregon and were the largest in the history of both states. Scientists say that both the increasing frequency and intensity of wildfires are largely responsible for prolonged droughts and increasing bouts of extreme heat from climate change.

July – Large parts of South America have been suffering from drought for a long time. While Chile is facing a decade-long drought linked to global warming, this year Brazil saw one of its driest years in a century. In Argentina, the Paraná, the second longest river in South America, fell to its lowest level since 1944. Around the world, heatwaves are becoming more frequent and more severe.

August – In the Mediterranean, a hot and dry summer sparked massive fires, forcing thousands to evacuate their homes in Algeria, Greece and Turkey. The fires, which killed two in Greece and at least 65 in Algeria, came amid a scorching heat, with some places in Greece recording temperatures of over 46 Celsius (115 Fahrenheit). (Climate change)

at the end of August – Due to global warming, almost all the mountain glaciers in the world are retreating. In the Alps, Swiss resort workers lay protective blankets on one of Mount Titlis’s glaciers during the summer months to keep the snow off. The government said Switzerland had already lost 500 of its glaciers, and could lose 90% of the 1,500 by the end of the century if global emissions continue to rise.

August/September – Hurricane Ida, which struck Louisiana as a Category 4 hurricane, according to the NOAA National Center for Environmental Information. About 100 people died in the United States and an estimated $64 billion in damage. As the remnants of Ida moved inland, heavy rains caused flash floods in the densely populated Northeast, greatly increasing the tornado’s death toll. Climate change is strengthening storms, while also causing them to stay on land for longer. Dumping more rain into an area before proceeding. Studies also show that these storms are becoming more frequent in the North Atlantic.

September – Infrastructure and homes in Russia are increasingly at risk as underground permafrost melts and deforms the land beneath them. Permafrost was once a stable construction base, with some areas frozen as far back as the last ice age. But rising global temperatures threaten the layer of ice, soil, rocks, sand and organic matter.

November – According to the United Nations refugee agency, the worst floods in South Sudan in 60 years have affected some 780,000 people, or one in every 14 residents. Each year the county goes through a rainy season, but flooding has set a record three years in a row. Scientists say that the probability of destruction will increase as the temperature rises.

November – A massive storm shed a month’s worth of rain in two days in Canada’s British Columbia province, causing flooding and destroying roads, railroads and bridges. It is possibly the costliest natural disaster in Canadian history, although officials are still assessing the damage. Meteorologists said the rain came from an atmospheric river, or a stream of water vapor, hundreds of miles long from the tropics. Atmospheric rivers are expected to become larger and possibly more destructive with climate change, scientists say. (Climate change)
