Humanity is now facing a visible threat of extreme weather conditions: warn the climate scientists.
While global warming today is resulting in herculean storms and drought driven forest-fires, it would be a mistake to treat these incidences as “new normal” and till the time the planet does not reach the stability of destruction, the near future will show the darker colours.
Thinking how warm it could get? The leaders across the globe have agreed (Paris Climate Agreement) that the countries would try and reduce the greenhouse gas emission to an extent that the average annual global air temperature is maintained to not more than two degrees Celsius above that at the beginning of Industrial revolution. Although the goals proclaimed by the countries at the signing of the agreement were to be met, mortal actioned global warming is predicted to reach around three degrees. Of course, concentrated efforts may result in maintaining the temperature, but the chances of keeping up to the goal is only about five percent, according to a scientific report (scientific report).
“Our study indicates that if emissions follow a commonly used business-as-usual scenario, there is a 93 percent chance that global warming will exceed 4C by the end of this century,” said Dr Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science.
Scientists were right in their predictions for all the events that have occured in the year 2017. The zapping earth would intensify hurricanes and hefty storms; while one part of the world will witness heavy rainfalls leading to floods, the other part will see widespread drought.
“If you talk to the leading economists who study climate change mitigation, they will tell you that the cost of inaction is already far greater than the cost of action — which is to say, doing something about the problem, imposing a price on carbon emissions, is a much cheaper option than the option of not doing anything and experiencing more of these devastating $300 billion or greater annual tolls from climate change,” says Penn State professor and atmospheric scientist Michael Mann.
“Pretty soon, we commit to the melting of much of the Greenland ice sheet and the West Antarctic Ice Sheet,” he continues, “and sea level rise, that thus far had been limited to less than a foot, starts to become measured in feet and then pretty soon in meters and yards.”
“So, there isn’t a new normal,” he concludes. “Things get continually worse if we go down this highway. What we need to do is to take the earliest exit ramp that we can in the form of decreasing our emissions and transitioning from fossil fuels to renewable energy.”
