A British newspaper today published a list of "100 reasons why global warming is natural". Here we take a quick look at the first 50 of their claims - and debunk each one.
1) There is "no real scientific proof" that the current warming is caused by the rise of greenhouse gases from man's activity.
Technically, proof exists only in mathematics, not in science. Whatever terminology you choose to use, however, there is overwhelming evidence that the current warming is caused by the rise in greenhouse gases due to human activities.
2) Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 per cent of the total naturally emitted from the mantle of the Earth during geological history.
Misleading comparison. Since the industrial age began human emissions are far higher than volcanic emissions.
3) Warmer periods of the Earth's history came around 800 years before rises in CO2 levels.
In the past 3 million years changing levels of sunshine triggered and ended the ice ages. Carbon dioxide was a feedback that increased warming, rather than the initial cause. In the more distant past, several warming episodes were directly triggered by CO2.
