A Simple Explanation of Climate Change Science

'The fossil fuel lobby repeatedly misrepresent science. One misrepresentation is the claim that the science of global warming is dependent on computer models. This is a total misrepresentation of the truth! The models are dependent on the science NOT the other way round.

The science is simple and based on measurements.
1. The global temperature is 30C higher than it should be based on radiation balance.
2. The 30C temperature rise can only be explained by the presence of greenhouse gases in the atmosphere. Without those greenhouse gases most of the Earth would be covered in ice.
3. If greenhouse gases increase the temperature will rise.
4. Greenhouse gases have increased.
5. The temperature has increased.

These all involve simple measurements that have nothing to do with models. The science is so basic that most of the work was not done in the 21st century, nor even in the 20th century but in the 19th century.'

this is an interesting post. perhaps you want to spell out degree because it comes across at 30C on my web browser.
Thanks!

More on why 20's plenty -- without need for any further 'trials'...

There are a number of reasons for setting a default speed of 20mph throughout the 'unclassified' road network in residential parts of a city such as Norwich. Most important perhaps is that of driver recognition as to what the speed limit is. If you have 20 mph as the default then you not only establish this limit clearly, but you also adjust the driver's recognition as to what is the "normal" speed in such residential areas. The most important aspect is that drivers set 20 mph as the norm with those 30 mph areas or roads being seen as 50% faster, rather than seeing 30 mph as the norm with 20 mph as 33% slower. The psychological adjustment of normal speeds in residential areas is key to the success of reducing speeds and therefore danger to pedestrians and cyclists. Therefore any trial, pilot or whatever, that only implements 20 mph in a tiny proportion of the city is not modelling 20's Plenty in any realistic manner.   When considering the val...

Stansted: a reflection

The key question, in relation to protsts like that at Stansted last week, is: which side are you on? Are you on the side of big corporations profiteering from completely unsustainable climate-destructive behaviour? Or are you on the side of people with no vested interests just making a non-violent stand, at considerable cost to their own time and money, for the sake of all our futures? It doesn't seem to me a hard judgement to make... Rupert Read Green Party Councillor, Norwich, and Lead Candidate for Eastern Region for the Greens in the 2009 Euro-elections.
