Description
In the 21st century, Planet Earth has been heating up, significantly, year after year. When it comes to the hottest temperature ever recorded, 2019 broke records across the globe while 2020 shattered them. What was once a naturally occurring seasonal event is now being attributed to the increase of carbon emissions that is wearing away at the Earth’s fragile atmosphere.
Unless the current trends are reversed, humanity is on a collision course to make more regions of the world uninhabitable, where boiling temperatures could be the new normal. It’s all due to one of the most deadliest weather events ever known: the Heat Wave.
One of the hardest heatwave events struck Europe in 2003 with a death toll about 70 000. The heatwave was especially hard in France, silently taking lives, putting stress on the healthcare services and causing city infrastructure as well as agriculture in the rural areas.
A recent report published by NOAA and NASA confirmed that 2010 to 2019 was the hottest decade since record keeping began 140 years ago. In July of 2018, new temperature records were set around the world and Death Valley experienced the hottest month ever recorded on earth. Heat waves that last for days at a time can be lethal; throwing public services and health care into chaos. They are caused by high pressure systems that hover over an area, absorbing heat beneath it like an oven.
High pressure systems push the air down. Hot air on the ground cannot escape to higher levels. Without ascending air, there are no clouds and no rain. The sun will simply cook a given area until some other pressure system is strong enough to push the high-pressure system away. But perhaps something more ominous is at work here. Something precipitated by man’s activities and the release of greenhouse gases. Some scientists now predict that in less than 20 years, millions of people in the U.S. could be exposed to dangerous heat conditions of up to 127 degrees Fahrenheit. We’ll speak with Dr. Michael Mann, one of the world’s foremost authorities on global warming. Dr. Mann will help to reconstruct the relationship between climate change and the unprecedented rise of life-threatening heat waves throughout the world.
