Emissions of a greenhouse gas that has 17,000 times the planet - warming capacity of carbon dioxide are at least four times higher than had been previously estimated.

Schlesinger and Ramankutty reach broadly similar conclusions, but they also point out that even though greenhouse gases now dominate global warming, if part of the warming during this century is indeed due to solar changes, the additional greenhouse effect may be weaker than was previously thought (Nature, vol 360, p 330).

It suggests that Earth will warm more slowly over this century than we thought it would, buying us a little more time to cut our greenhouse gas emissions and prevent dangerous climate change.

As part of its strategy to reduce greenhouse gas emissions to prevent global warming from exceeding 2 °C (3.6 °F), the Obama administration unveiled a plan in September to build wind farms off of nearly every U.S. coastline by 2050 — enough turbines to generate zero - carbon electricity for more than 23 million homes.

But then how to explain a similar rapid warming that occurred during the early 20th century, when the effects of greenhouse gases were considerably weaker than today?
