Dear MEL Topic Readers,
September was world's 'hottest on record'
How was the last September to you and in your place? Did you feel it warmer or hotter than the previous years or decades ago despite the social distancing from other people? If you live in the northern hemisphere or around the equator, you most likely ran air-conditioning longer in September as it was 0.05C warmer than last year. In fact, it was the hottest September on record. You might think 0.05C is not so worrisome but it adds up in the long run. Imagine the temperatures keep rising at the same rate for decades, it will be 1.5 degrees Celsius hotter by the middle of the century from now, which means it’ll be much higher from decades or a century ago. Please be reminded that a century is much less than a millisecond for earth’s 4.5 billion years history. Indeed, world temperatures and landscapes are changing at an unprecedented pace.
What is needed to avoid disastrous climate impacts is simple. More reduction of the greenhouse gasses than increase, which requires more action than discussion.
Enjoy reading the text and imagine what the summer is like ten or twenty years from now.
