A new study has discovered that the current state of global warming could have been a lot worse if the world’s nations hadn’t successfully agreed to take measures to save the planet’s ozone layer, and phased out the production and use of numerous ozone-destroying chemical compounds. And the temperature difference
A new study has found that the temperature increases from global warming may be twice as bad over what previous climate studies have forecast. This study made use of historical data from previous geological periods when Earth’s climate was 0.5°C-2°C warmer than the 19th Century’s pre-industrial average, illustrating that the consequences of runaway global warming could spell the collapse of many ecosystems, ranging from the Sahara Desert becoming green, to tropical regions converting to a fire-prone savanna.
The infamous hole in Earth’s ozone layer has shrunk down to 7.6 million square miles wide (12,200,000 square kilometers), the smallest the gap has been since 1988. This healing of Earth’s main shield against ultraviolet radiation is due largely to efforts initiated in the mid-1980s, when the use of ozone-harming CFCs was phased out. Not only is this positive news in regards to our atmosphere’s ability to filter out harmful UV radiation, it also stands as an example of how humanity can make a positive, large-scale impact when efforts to reduce ecological harm are required, such as in the case of our need to reduce greenhouse gas emissions.
