The world isn’t warming as fast as our best climate models predicted it would, and scientists are trying to figure out why. A group of American researchers now believes extra volcanic activity may be responsible for the lack of warming over the past decade. The Independent reports:
According to a study in the US, models for predicting the rate at which temperatures around the world would rise from 1998 onwards did not take into consideration the measurable impact volcanoes can have.Rather than contributing to global warming, eruptions release particles into the air that reflect sunlight – causing temperatures to drop.
This isn’t the first explanation scientists have alighted upon in defense of faulty models. Earlier this month a different study pointed the finger at equatorial ocean currents, which they said were helping store surface heat deep underwater.None of this uncertainty does anything to undermine the basic argument for man’s contributions to climate change (the greenhouse gas effect remains fairly easy to understand), but it is devastating to the credibility of the computer climate models that greens have often used to back up their preferred policy mechanisms for dealing with the problem.We don’t yet actually understand how the climate works to the extent that we can make reliable predictions about it. That is hopefully changing and getting better, but greens aren’t doing themselves or the environment any favors at all by claiming the science is more settled than in fact it is. Green fact-hyping remains in our view the leading cause of climate skepticism.
