How Climate Change Has Greatly Impacted the World

The World Meteorological Organization (WMO) has published its annual report Statement on the State of the Global Climate for 2019. The data provided by the document are not positive. The trend that has been seen in recent years continues. And there are no signs that it will be reversed. The WMO report notes that the 2019 average temperature was 1.1 degrees higher than the pre-industrial era.

The month of July 2019 was the hottest of all time since records exist. As for the year as a whole, it was the second hottest. The first remains in 2016. In a broader view, the WMO report lists the decade from 2010 to 2019 as the hottest so far. It is perhaps the most visible consequence of climate change.

It should be noted that since the 1980s there has not been a decade that is less hot than the previous one. In other words, each new decade has a higher average temperature than its predecessor. This causes the accumulated temperature to rise dangerously.

When it comes to less global records, Australia is on the front line. The southern country had its driest and hottest year. Hence the large number of fires that devastated the country in recent months. Its hottest month was January and the day the temperature rose the most nationwide was December 18.

The Need To Curb Heating

The UN has already warned that in 2030, the planet will reach the key limit of 1.5 degrees above pre-industrial temperature. This is the rhythm that is currently being carried out, but it is a situation that you want to avoid. And is that the consequences of this would be unpredictable. The Paris Agreement already established that emissions had to be controlled to avoid this extreme. The limit is between that 1.5 degree and 2 degrees. Anything that goes beyond it can be disastrous for the planet.

To end climate change many ideas have been proposed. Some of them are even outlandish plans, like that of Harvard University professor of Applied Physics David Keith. He was the one who proposed spraying sulfuric acid at an altitude of 20 kilometres in the tropics. In order for the sulfur to combine with the water vapour, it becomes a sulfate spray. This would generate a capac that would reflect a percentage of sunlight. It could reach 1%.
