1) Temperatures are rising - Wrong. Satellite and radiosonde measurements have detected no increase in global temperatures over the last two decades. Only land-based measurements, which are subject to urban 'heat island' effects, have shown any increase.
Land based measurements are generally more accurate than remote sensors, yet you dismiss them - it must be your old friend coincidence that makes 10th Aug 2003 the hottest day ever recorded!

2) Sea levels will rise - Wrong. Increased sea temperatures will result in more evaporation, and more precipitation of snow over the ice caps - resulting on both counts in a drop in sea levels.

3) Glaciers are retreating - Wrong. Some are, but others are advancing. You only hear about the ones which are retreating. Glaciers are very slow-moving rivers of ice - decreased snowfall at the source of a glacier will have the effect of less flow at the foot of the glacier several decades later.
You said above that temperatures are NOT rising, yet now you say that there will be drop in sea levels because of it. Make up your mind! I was Mission Operation Engineer on
this mission, which can remotely sense glacier progress and ice sheet progress. Many of the findings conflict with yours.

4) High CO2 levels will cause runaway heating - Wrong. CO2 levels have been orders of magnitude higher than today in bygone ages - with no evidence of runaway heating. Ice core records also show that high CO2 levels have historically followed times of high temperatures - rather than being the cause of them. This is because as the oceans warm they release large amounts of dissolved CO2 into the atmosphere.
Does this have any relevance whatsoever to the modern era? Do you think we care about what happened a million years ago or what will happen a million years hence. We are in a epoch that is stable enough to sustain us and our children NOW, and we want to keep that epoch around for the duration! An condition stable enough for slugs and worms might be fine for you, but not me!
<PS I do not impute that you are a slug or worm, although I realise now that you could read that into the sentence above !>

5) An few degrees increase in global temperatures will be detrimental, and cause a huge increase in storms, hurricanes etc - Wrong. Temperatures have been higher than today within recorded history. For example, in medieval times - wine was grown as far north as York, and Greenland was settled by the Vikings. It was a golden period for agriculture. The worst storms in recorded history occurred during the Little Ice Age, when it was several degrees colder than today.
Temperatures have changed more over the past 30 years than at any other time, corresponding with the increase in industrial pollution. Increased freshwater runoff and Northern river ice breaking up earlier is threatening the gulf stream conveyor. Winters have warmed, and summers have been the hottest ever recorded. Permafrost in Alaska has melted and houses have sunk into the ground, glaciers are shrinking, the sea ice is melting. The ice caps are thinning.

6) There will be an increase in diseases such as malaria - Wrong. Malaria isn't a tropical disease, there was a time it was endemic in Russia.
I guess I’ll have to trust you on that.
