Global warming is a complicated subject! Earth actually cooled in the lockdown period with less pollution being made by man. The same was noted after planes were stopped after 9/11. Clean alternative power systems are still vitally needed for our clean air and habitat. The oil fired combustion engine is dirty and outdated and makes us rely on unscrupulous oil companies who have shown themselves only interested in profit above humanity. Mother earth truly calls the shots... one volcano can produce more particulates than mankind in an instant, but wether Earth is warming or cooling we must be more aware of our wildlife, habitats and as a species make less needless waste. We can no longer childishly landfill our plastics as they now can be found in every seoceana, it is time to wise up planet Earth!
