48 people died in 5 days!
No, it's not a corona-meter figure. Terrible heat waves are burning Canada and a large part of North America. And in Canada alone, nearly 500 people lost their lives in 5 days!
The worst situation is in Lytton, British Columbia. The temperature there reached 49.5 degrees Celsius this week! While temperatures are normal in the desert city of Rajasthan, British Columbia has an average temperature of 12-15 degrees Celsius in June, which is like a 49 degree scare.
Not only record-breaking temperatures, but even greater dangers have befallen Litton. Terrible fire has started. The mayor ordered the city to be evacuated immediately on Wednesday. In fifteen minutes, almost the whole city is on fire! The same is true of Vancouver. Those who do not have AC in their house are running to small hotels, where at least a little bit of life can be saved by renting an AC room. AC is selling at three to four times the price! The demand for electricity has also increased several times in one go. The picture in Washington, Oregon is not very different.
But why? What is the cause of this sudden heat wave in large parts of North America, including Canada?
In this context, the theory of 'Heat Dome' is coming up. The dome of hot air is formed when the hot air of the sea is pushed towards the surface by the atmosphere like a lid. In this case, hot air cannot escape, so the heat flow continues on the surface. Since this situation is not conducive to cloud formation, the radiation of sunlight raises the surface temperature, and that is what brings danger! The same thing happened in Canada and North America.
Professor Tuhin Ghosh, director of the School of Oceanographic Studies at Jadavpur University, says the jet stream in the Pacific Ocean causes hot water to flow north and cold water to flow south. A mixture of these two types of water creates a high pressure and a low pressure over the ocean. The hot air of high pressure cannot fall out between the low pressure of both sides. Then it can come down to a nearby land. And holding it like a lid to the atmosphere creates a 'hit dome', which has spread to large parts of Canada and North America. According to most experts, this can happen once in a thousand years. But as a result of climate change and global warming, it will not be a surprise if this happens again and again.
But heat waves also occur in India. Is it normal to die near 500 in just 5 days?
Tuhin Ghosh explains that Canada is a cold country and people are not used to it. And that's why so many people are dying of heart attacks in extreme heat, most of them elderly. In India too, several places in northern India, including Delhi and Punjab, have been warned of heat waves for the next two days. But due to the geographical location of India, there is no possibility of building a 'hit dome' here, assured the professor from Jadavpur.
But danger awaits America. The 'hit dome' usually lasts about a week. But then the temperature in Oregon or Portland can drop from 45 to 15 degrees Celsius if the hot air comes out suddenly. Experts warn that many more deaths could occur if the shock is not tolerated. According to Karin Bumbako, a climatologist in Washington, the 'Hit Dome' situation has been created before. But now climate change is working a lot like a 'steroid'.
What is it like?
According to Tuhin Ghosh, the temperature in Canada could have risen to 41-42 degrees Celsius in the 'Hit Dome' situation as it was 100 years ago. But now global warming has increased the average temperature by 3-4 degrees. As a result, the temperature in Canada is exceeding 49 degrees Celsius! This dire situation reminds people once again of reducing environmental pollution and greenhouse gas emissions. But people will learn so much?
