We are given to understand that anthropogenic carbon-dioxide emissions will lead to increases in global temperatures, with potentially catastrophic consequences. But is this true? Below are links to my own investigations into the issue,
1) My brief review of measured global average temperature data is here. Yes, global averaged temperatures have been increasing.
2) CO2 levels in the atmosphere are increasing, and will be double the pre-industrial level by about 2060 to 2080 if current trends continue. I have produced my own simple model which agrees with the claim that the CO2 increases are likely to be anthropogenic: see here.
3) The standard claim is that CO2 is causing the global average temperature to rise. We are told "the science is settled". But it isn't: see here.
4) However, the IPCC climate models are stable, see here.
5) My analysis of changes in Arctic and Antarctic sea ice is here. Not as dramatic as you have been led to believe, but there is some reduction.
6) Is the rise in global averaged sea level due to CO2? I address the question here. Mostly, no.
7) Is Climate Change to blame for the recent Australian bush fires? I think not, as there is no statistically significant trend in Australian bush fires over the last 19 years, as shown here.
