From a call for papers I received:
Within the scientific community, the phrase “climate change” is replacing “global warming” because Earth is not just getting warmer. It is also changing, and changing in ways that scientists are just beginning to explore.
Sea levels are rising, glaciers are melting and shrinking, plants and trees are blooming earlier and in places where they have never bloomed before, growing seasons are lengthening, polar permafrost is thinning.
The scientific debate is changing as well, moving away from whether and why we are warming, to what effects climate change will have on Earth’s environment, and just what exactly is causing it. Is it simply human output of greenhouse gasses? Is it a natural climatological progression?
To sum up:
- Scientists are now focusing on “climate change”, not “global warming”. (Climate can cool or warm.)
- The Earth’s climate is getting warmer, with notable effects.
- Scientists are focusing no longer on if and why we are warming, but how climate change (warming effects) will affect the Earth
- Scientists are focusing on why the earth is warming/changing.
- Global climate change might be a natural phenomemon or it might be caused by greenhouse gasses (which are supposed to cause warming.)
