After a long hot summer..
It’s sobering to read the latest news on global warming. I subscribe to the National Geographic newsletter and have been avidly following the discovery of a dinosaur that makes the T-Rex look like a pussy cat as well as the `Judas Scrolls’ but it is the articles on global warming that claim most of my attention. National Geographic News treats this subject with great clarity with no screaming headlines, making the impact even stronger.
In this story it is estimated that there could be mass extinctions of animals and plants by 2050 - that might seem like a long way off, but believe me, 2001 seemed like a long way off when I was young.
Even a story on projections that seem to show the earth’s climate is less sensitive to greenhouse gases than previously thought do little to lift the spirits - as Gabriele Hegerl, a climate scientist at Duke University in Durham, North Carolina, said; “[The finding] means the climate does react significantly to greenhouse gases,” she said.”In other words,” she added, “we have really detected greenhouse warming, and we are really concerned it is not small.”
