Reasonally proper regular temperature records only go back to around 1840s, but we know there have been ice ages and the earth was warmer than now when there were dinosaurs. historical records tell us there were a lot of winters in 1700s where the Thames was so regularly frozen that there were organised winter markets on it. Krakatowa erruption in late 1880s caused world temperatures to drop a couple of degrees for the next few years because of the amount of ash it blew up into the atmosphere. We cant conclusively say mankind is causing the increase in temperatures (& that its not a coincidence)... but we can reduce the pollution we cause & hope that it helps.

For instance, the amount of carbon dioxide in the atmosphere has increased by about 35% in the industrial era, and this increase is known to be due to human activities, primarily the combustion of fossil fuels and removal of forests. Thus, humankind has dramatically altered the chemical composition of the global atmosphere with substantial implications for climate. From the very same report, and I found that in 2 minutes reading.
In climate research and modelling, we should recognise that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible.
Extreme events are, almost by definition, of particular importance to human society. Consequently, the importance of understanding potential extreme events is first order. The evidence is mixed, and data continue to be lacking to make conclusive cases.

Doctor Jimbob wrote: » I agree that the science has been politicised, yes. There's definitely an element of using climate change as an excuse to increase taxes, etc, and I'd have serious doubts that those implementing these increases are doing so as a result of a genuine concern over climate change. The issue I have with your stance is that instead of simply questioning things (which is a good thing, IMO), you go all in politicising things in the other direction. Your entire stance seems to be based on an irrational, conspiracy theory level distrust of the UN and socialism. You assert that politicised science can't be trusted, yet in the same post go on to spout your own brand of politicised science. Do you genuinely not see the hypocrisy here?

It's just a username, I'm not a real doctor, although given the kind of places conspiracy theorists tend to get their information from, maybe the difference isn't too distinct to you.

Maybe the research is flawed, maybe it isn't, but if it isn't surely something more recent would have come out backing it up?

Unless you're saying that these two are somehow not connected (arguably the biggest coincidence ever) then it's quite blatantly obvious that we're causing this. Added to the facts that scientists have regularly proven that CO2 emissions cause a negative effect on the Ozone layer etc. An ice-age or mega-volcano eruption would cause a huge, short term- shift in temperatures as you already pointed out above with that example, whereas what we are seeing now is a very gradual change over the last 150 years. Anyone who really doesn't believe that humans and our lifestyles are what's causing climate change is deluded and completely in denial because they don't want to accept the idea that our lifestyles need to completely change for our children and grandchildren not to suffer the severe consequences it's going to bring.

While Prof McPherson appeared to be very knowledgable about his areas of expertise - ecology and biology - there were serious problems with his understanding of atmospheric physics, and he exaggerated some key figures by up to 10 times.

And of course they'll never accept it. Hence a circular neverending "debate" like this trainwreck
