| Climate scepticism: The top 10 BBC NEWS | Special Reports | 629 | 629 | Climate scepticism: The top 10 6. CLIMATE IS MAINLY INFLUENCED BY THE SUN Sceptic Earth history shows climate has regularly responded to cyclical changes in the Sun's energy output. Any warming we see can be attributed mainly to variations in the Sun's magnetic field and solar wind. Counter Solar variations do affect climate, but they are not the only factor. As there has been no positive trend in any solar index since the 1960s (and possibly a small negative trend), solar forcing cannot be responsible for the recent temperature trends. The difference between the solar minimum and solar maximum over the 11-year solar cycle is 10 times smaller than the effect of greenhouse gases over the same interval. |

| Despite Fox News and Rush Limbaugh, we are not experiencing Global Cooling Blogs Scientific American Community this refers to dailytech directly. "The bottom line is that one year does not a trend make... but a hundred years of increasing C02 and temperatures... now that's a trend." |

| Too bad that the rising temperatures come before the rising CO2. Do you think that it might be that the rising CO2 is because the temps were rising?

| Same link BBC NEWS | Special Reports | 629 | 629 | Climate scepticism: The top 10 7. A CARBON DIOXIDE RISE HAS ALWAYS COME AFTER A TEMPERATURE INCREASE NOT BEFORE Sceptic Ice-cores dating back nearly one million years show a pattern of temperature and CO2 rise at roughly 100,000-year intervals. But the CO2 rise has always come after the temperature rise, not before, presumably as warmer temperatures have liberated the gas from oceans. Counter This is largely true, but largely irrelevant. Ancient ice-cores do show CO2 rising after temperature by a few hundred years - a timescale associated with the ocean response to atmospheric changes mainly driven by wobbles in the Earth's orbit. However, the situation today is dramatically different. The extra CO2 in the atmosphere (35% increase over pre-industrial levels) is from human emissions. Levels are higher than have been seen in 650,000 years of ice-core records, and are possibly higher than any time since three million years ago. |
