Today, we are faced by the possible disappearance of at least 5% of animal species on Earth before our children die and 10-15% more before our great-great grandchildren take over the world (This assumes the age grouping from 30-70, average age 50.) This will affect all lifeforms from bacteria to human beings.
What is happening is that land organisms will run out of land as seas rise. Entire island based environments will simply disappear. Organisms that rely on a specific temperature range to survive will have to establish new ranges. Those that live near the poles will have no place to go as warmer temperatures create an uninhabitable environment with no available alternative.
One of the starkest images is that of Mount Killmanjaro. Here it is in 2008:
Today, it is far worse, most of the ice field to the left is entirely gone. I could not find images without copyrights.
In 1950, it was a snow covered mountain at the same time of the year the image above was taken. When Hemingway wrote his epic novel, it was a land of ice and snow. Now, it is the rock slides that occur as the ice glue that kept them in their place disappears.
What organisms that inhabited this mountain will either lose their niche or have lost it.
Those, below, who depended on the spring melts are also feeling the pinch.
And, by the way, nations are meeting in Denmark in order to discuss the problem. We are confined to a single planet. Mountain, planet – it is all a matter of scale. Those people orbiting in the ISS can not survive without support from the surface. In truth, we are all in the same boat.
