What are several predicted effects of climate change?

Answer 1

Current science projections by the IPCC were released in their 2007 report. This report was created by a handful of Climate experts and hundreds of political experts. (This is the most pro AGW group around). They have always projected far in excess of any actual events. They produce no science studies, but rather collect and interrupt what is done by other groups. The current projections are:

That if the temperature would continue to increase for the next few centuries to the next millennial, ice could at least partially melt from Greenland and West Antarctic ice sheets. This would require a temp increase of 1 to 4 degrees C over the next 1000 years, (relative to 1990 averages). This would cause flooding due to a sea level increase of 5 to 7 m. (There is medium confidence of this prediction 50-50 shot )

There would be increase yields in food production over the next few hundred years in High Latitude areas. (Very Likely 90% chance)

Weather extremes are likely to increase in volume and intensity. (likely is 66% chance)

To get the whole report you can go to the IPCC website and ask for the fourth assessment. They have always over reacted and been too extreme in every report they have ever produced.There is far more politics involved then any science. The data is so bad for the pro side they have been caught many times fudging numbers to make it look as though warming is happening.
