Why I think we're wasting billions on global warming, by top British climate scientist
...We need to rethink. For instance, if you suppose that the annual UN climate talks will save us, forget it. I met a delegate at the last talks in Doha in December who told me he had just watched a two-hour debate that culminated in placing square brackets around a semi-colon.

Since Kyoto, world emissions haven’t fallen – they’ve risen by 40 per cent. And these vast jamborees – some involving more than 10,000 people – haven’t even started to discuss how we are going to limit the total amount of carbon we dump in the atmosphere, which is what we actually need to do to avoid dangerous climate change.

While failing to delay CO2 levels rising through the 400 parts per million level, Kyoto and the policies which stem from it have achieved the loss of jobs from countries such as Britain – where we have at least managed a small reduction in the emissions we produce – to others whose factories are far more carbon-intensive.

As my Oxford colleague, the economist Dieter Helm, noted in his book The Carbon Crunch, we may have cut the CO2 actually emitted here, but our reliance on imports means the total emissions attributable to British economic activity have increased by 19 per cent since 1992....

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide
...“Most conventional theories expect that global temperatures will continue to increase as CO2 levels continue to rise, as they have done since 1850. What’s striking is that since 2002, global temperatures have actually declined – matching a decline in CFCs in the atmosphere,” Professor Lu said. “My calculations of CFC greenhouse effect show that there was global warming by about 0.6 °C from 1950 to 2002, but the earth has actually cooled since 2002. The cooling trend is set to continue for the next 50-70 years as the amount of CFCs in the atmosphere continues to decline.”...

...Lu’s theory has been confirmed by ongoing observations of cosmic ray, CFC, ozone and stratospheric temperature data over several 11-year solar cycles. “CRE is the only theory that provides us with an excellent reproduction of 11-year cyclic variations of both polar ozone loss and stratospheric cooling,” said Professor Lu. “After removing the natural cosmic-ray effect, my new paper shows a pronounced recovery by ~20% of the Antarctic ozone hole, consistent with the decline of CFCs in the polar stratosphere.”

By proving the link between CFCs, ozone depletion and temperature changes in the Antarctic, Professor Lu was able to draw almost perfect correlation between rising global surface temperatures and CFCs in the atmosphere....
