When Global Warming comes up, I often hear, “So what? The temperature’s only gone up like, what? One degree? Ha! Big fat deal!”
The “one-degree” temperature data came independently from land stations and ships, which greatly correspond since thermometers came into widespread vogue around 1850.
From this data, the combined best estimate of global surface temperature change is a 0.6 degree C increase. For the Celsius illiterate, that’s 1.8 degrees Farenheit, which is closer to TWO degrees than one. Still, you say, what’s the big deal?
Global Warming In Progress
Below are two photographs of Muir Glacier in Alaska’s Glacier Bay National Park.
The top photo was taken on August 13, 1941. The bottom photo was taken on August 31, 2004. Seven miles of ice replaced by a valley full of ocean water. Foilage where it was once too cold to grow.
That’s the difference.
