In other words, natural factors could be more important than previously assumed'. Sun and water WITH Dr Sallie Baliunas, another astrophysicist at the centre, Dr Soon is well known for arguing that most global warming is actually caused by changes in the amount of energy the sun emits. When the Danish National Space Centre looked at 400 years of sun spots and global temperatures, it found that when sun spot activity rose, global temperatures rose too - and vice versa - with no time lag. The record even showed a dip in solar activity in the 1945-1975 period of global cooling noted earlier. The sun's direct rays heat up the air which then heats up the land . More importantly, solar activity impacts cloud formation . Specifically, when cosmic ray particles penetrate the Earth's atmosphere, they meet water vapour rising from the oceans to form water droplets, which coalesce to form clouds. The more cosmic rays, the more clouds they help create, the cooler the air gets. Cosmic rays come from exploding
stars called novas. When solar activity increases , what happens is that the sun's magnetic activity increases. When that occurs, cosmic ray particles tend to get blocked off, so fewer penetrate the Earth's atmosphere and thus fewer clouds form . So when solar activity increases , the sky is less cloudy. With less cloud cover, temperatures rise . In short, global temperatures are controlled by clouds (water vapour), which are controlled by cosmic rays which , in turn, are controlled by the solar activity. If the engine driving the Earth's climate change is the sun - not carbon - and the transmission belt is water, then the impact of human activity on global temperatures must be small . It's a good thing then that Singapore has no binding carbon emission reduction targets under the Kyoto protocol.
1NC Solar Variations/Rays Solar activity and cosmic rays correlate with changes in temperature while CO2 levels do not – IPCC models ignores this Carter et. al, 15 – [Robert M., Ph.D. and a geologist and environmental scientist, is emeritus fellow of the Institute of Public Affairs in Australia and author of Climate Change: The Counter Consensus; Craig D.

Having concluded solar forcing alone is inadequate to account for twentieth century warming, IPCC authors infer CO2 must be responsible for the remainder. Nonetheless, observations indicate variations occur in total ocean–atmospheric meridional heat transport and that these
