Could Greenhouse Gases Cause The Oceans To Overheat?
New Research Suggests Could Overheat Sooner Than Previously Thought
Two recent studies published in the journal Nature Geoscience have found that the amount of energy needed to shift a planet’s climate into thermal overdrive at Earth’s distance from the sun was about 10 percent less than previous estimates.
University of Victoria researchers Tyler Robinson and Colin Goldblatt discovered a lower thermal radiation threshold for the runaway greenhouse process. The so-called runaway greenhouse effect occurs when a planet absorbs more energy from the Sun than it is capable of radiating back into space.
If a planet absorbs more energy than it can emit, it will heat at an uncontrollable pace leading to the evaporation of the oceans. The research suggests it might be easier than once thought for planets to overheat, reports R&D magazine.
The research suggests that from a standpoint of Earth’s climate, it would likely take another 1.5 billion years, even accounting for the pace at which human activities are pumping greenhouse gases into the air, for a runaway greenhouse effect to take over, says Colin Goldblatt, an assistant professor at the University of Victoria in British Columbia who studies the evolution of Earth’s climate.
A planet reaches the runaway greenhouse stage when it absorbs more solar energy than it can give off to maintain equilibrium. This causes the world to overheat, which eventually leads to a planet becoming inhabitable.
Lesser-known Plagues Can Be As Devastating As MERS, Ebola
There are the diseases we know well – MERS, West Nile virus, and HIV. And there are the diseases we really know about much – potato blight and wheat rust.
We should. This is the contention of the National Geographic, which has identified the plagues which have the potential to devastate crops and ruin nations.
