Global Warming is Getting Very Real, Scientists
2014 has been declared the hottest year on record by the weather and climate agencies around the world. Does that mean that the threat of global warming is very real? All these years, there have bene speculations over the computerized climate models and the flawed future temperatures, as well as an overestimation of carbon dioxide's warming effect. All these reports have been casting a doubt on man-made global warming, and how real or risky is the threat as reported by Washington Post. How accurate are those models based on warming effects of greenhouse gases like CO2?
It is true that many models are not able to predict the modest surface-warming correctly. As apparent from the recent studies, the researchers report that the computer simulations can forecast "chaotic" changes in the climate system in short-term, and those reading can add or subtract warming effects from CO2 emissions temporarily. There is no denying that the temperatures of air have increased at a slower pace in the past decade, as compared to the predictions made by the computer simulations. The scientists are trying to figure out as to why the temperatures didn't rise as much as anticipated according to Real Science.
Well, one reason behind is attributed to the cyclical processes in the Earth's climate and the momentary changes in the solar radiation reaching the Earth's surface. These can lead to an unpredictable warming trend of the Earth's surface. The oceans today could be absorbing much more heat from the atmosphere. Other factors could be a rise in the light-reflecting aerosol pollution and the temporary downturn in solar output. All these aspects could have slowed down CO2-driven warming.
Science Recorder says that the researchers and scientists are looking for the climate models and checking out if they are biased. It is essential to see as to how those temperature predictions stand against the reality and whether those models overestimated or underestimate the temperatures.
