Nonsense predictions from the MET Office in 2000
These were the MET Office predictions in 2000. Note that we are in the high emission scenario and absolutely none of those things actually happened.
The sea level rose at most by about 4-5 mm.
Sea surface temperatures increased by at most 0.2-0.3C.
pH decreased by at most than 0.03 - the margin of error is greater than the alleged decrease.

I don't see how Permafrost is decreasing with the extreme cold and snow cover over Siberia, over multiple years.
