This looks as though it could be due to a difference in the data as '64 is easily the coldest year in that period according to GISS whilst the HadCRUT graph suggests that '76 is the coldest.

SNIP However, I am worried that the authors take 1979 as the starting point for their data because that is precisely when the sudden upturn in warming began. The advantage to the pro-lobby is that they dont have to explain the drop in global temperatures over the previous 20 years. (This gives ammunition to the antis, and also the GW agnostics such as myself.) Nor does this 1979 starting point have to explain the sudden switch from a slow fall to a rapid rise around the late 1970s. I don't agree that 1979 marked the beginning of the sudden rise in temperature. Looking at an 11-year rolling mean, the rise started at the start of the 70s rather than at the end; the rise from 1971 to 1980 was 0.12C. People mention the sudden surge in car ownership and the installation of central heating in many first world countries, installation but there is supposed to be a ~20 year time lag between cause and effect, so that would imply a sudden change of energy use around the late 1950s. Again, going by the 11-year rolling mean, the fall in temperature occurred during the 40s with a rise in the 50s and flat-lining in the 60s. (1942-51 fell 0.12C, 1951-62 rose 0.08C, 1962-71 wobbled between 0.01 and 0.02C below the 51-80 average). When looking at the behaviour of global temperatures from 1940-1970, I think it might be worth looking at what was happening to CO2 levels after the Great Depression. There was slowing down in the increase in CO2 during the 30s and from 1940 there was even a very slow fall. CO2 levels did not recover above the 1940 level until 1948. I'm not saying this is largely to blame for the hiatus in the rise in temperatures during the past century but it may have had a part to play. I was using these graphs for my statements:- http://www.cru.uea.ac.uk/cru/data/te...e/HadCRUT4.png Just shows what difference the smoothing method makes. ;-) I'm also using GISS data as the Met Office data ignores the Arctic. Not sure how they can get away with calling it 'global' when they make no attempt to include the most important area. The GISS data is also stored in a more convenient format. I stuck to 11-yr rolling mean to rule out any solar-cycle effect - not that there seems to be much evidence of one. Of course, when I use a shorter-length period, I get more of a saw-toothed graph - like the HadCRUT - with a sharp rise starting in the mid-70s though it could be argued from the 5-yr rolling mean that the real rise started in '67.

Graham P Davis, Bracknell, Berks. Graham I thought Mauna Loa only started accurately measuring from 1956? I also have to ask why do you see co2 as the only driver of climate when through our present ice age climate has driven co2. It's such a minute trace gas and the human contribution so small and yet you and others have tagged so much onto the AGW theory that yo cannot accept any other factors. If the numerous studies of the Greenland and Antarctica ice core samples show that way before and animal on earth released co2 from fossil fuels and wood, peat etc. that the earth seemingly lurched into full scale glacial periods in as little as twenty years and all that with nasty humans Oh dear. The "It's only a trace gas, so it must only have a trace effect" syndrome. Read and understand (doubtful) this and it will disabuse you of that notion. CO2's contribution to atmospheric warming has been known (though the amount has been refined) for 150 years: http://www.jcsda.noaa.gov/documents/...fraRadTran.pdf PS If you don't think a trace amount can have a big effect, try sprinkling a tiny amount of ricin , or strychnine, on your sunday lunch. What a silly thing to say and it just shows ignorance about the science. PPS No scientist sees CO2 as the only driver of climate. Why would you think they would? |

There is a video here where a climate scientist gives his views of the state we are in with regards to global warming. http://vimeo.com/43012713 Of course, those who should watch it won't :-( Cheers, Alastair. On the other hand, read "Climate: The Counter Consensus" by Prof. Robert M.Carter, an erudite work which comes to some rather different conclusions. I believe it is reviewed by readers on Amazon. With the experts so much at variance I think one has to keep a strictly open mind on this vexed topic. It doesn't even seem to be decided whether increased CO2 causes global warming or whether it is the other way round. Ian Bingham, Inchmarlo, Aberdeenshire. |

... Before I start am I allowed to take an anti panic view on this topic without upsetting anyone and being called a right wing fascist? Just want to get that clear. Dear All, Perhaps I should make it clear to everyone that the "debate" is not between rival scientists, or between rival bloggers slagging each other off. It is between sober respected scientists such as Stefan Rahmstorf http://www.pik-potsdam.de/~stefan/ and American right wing "think tanks" funded by bilionaires. http://www.guardian.co.uk/environmen...ktanks-network The think tanks are using the same tactics, and in some cases the same personnel, that were used by the tobacco industry. Just as it was not possible to disprove that smoking caused cancer, it is also not possible to disprove that CO2 is causing global warming. So their tactic is to rubbish the scientists and throw doubt on the science. As long as the public do not trust the scientists then the politicians cannot take action for fear of losing office. The point to realise is that the think tanks can use every dirty trick in the book. The scientists must follow their unwritten code or find themselves excluded from their profession. One of the dirty tricks played by the sceptic bloggers is to insult the science bloggers with abusive language hoping to inspire retaliation. (This tactic is now common in football where slagging is used with the hope of having an opponent sent off for retaliation.) In the climate debate this works, resulting in posters here complaining about the debate being just a boring slanging match, exactly the reaction that the sceptic think tanks want. And that is the impression that Lawrence's opening gambit reinforces - that I am going to descend into political name calling. I posted a video about a scientific fact. The ice sheets are melting and it will soon be impossible to save them. I am not going to be dragged into a debate about whether global warming is happening or about my or Lawrence's politics. Cheers, Alastair. |

I’ll continue to read as widely as I have time for and keep an open mind. Ian Bingham, Inchmarlo, Aberdeenshire. I didn't say they aren't at variance. I painted a very clear picture of just how big the consensus is from 2 studies and it looks like you don't like that. Did you read the studies? If you have evidence to the contrary, Show it instead of waving your arms about a lot and talking about "bandwagons" and self-righteous sticks (whatever they are). PS Every scientist has an open mind. It's just that the incredibly vast majority don't keep it so open that they fall into it and they recognise the enormous consensus in favour of Co2 being the main driver of the current warming. |

It's funny that anyone could react in this way and I'm so pleased that no-one with an ounce of influence listens to people like this when they spout this stuff, but I'm even more pleased that my grandchildren's children's future is not in the hands of people like this. |
