September 1, 2020 The good news, such as it is, goes like this: the suspense is over. No need to guess about whether sea level rise will be life-altering by the end of this century or not. It will, at least for the 40 percent of humankind which lives on or near a coastline. That's because all the ice on Greenland is going to melt, according to researchers at Ohio State University (yes, yes, I know - it's THE Ohio State University. Get over yourselves.) Their research appeared in the journal Nature Communications Earth and Environment in August. Total meltdown will take 10,000 years, but enough will have melted by 2100 to cause sea level rise of approximately three feet. That will cover a lot of coastal property, a loss made worse by storms and hurricanes. How have researchers reached this conclusion? By studying almost 40 years of satellite data. Glaciers on Greenland have shrunk so much since the year 2000 that even if global warming came to a complete stop, they would contin
I was listening to Science Friday on NPR today, and Ira Flatow said that increasing numbers of people now understand that climate change is really happening. He or a guest remarked that many of those same people ask, What can I do to improve the situation? Since that's a subject I haven't written about in awhile, and since there is so much each of us can do, let's talk about it. Where to start - what we eat? what we wear? what we drive? There are right answers to each of those questions. If you're eating conventionally grown food, that needs to change, because foods that "require" chemicals to be grown are killing all of us, both because of airborne pollutants, and because of the poisons that wind up in our bodies. While it is difficult to eat a diet that consists only of organic foods, there are so many organic options (especially produce, dairy foods, and meat) that you should acquaint yourself with what's available. The end result will be healthier bo
