Climate change Global Action Delay

Climate change Global Action Delay there is a new study finds that delaying global action on climate change by 20 more years is not only making the effort more expensive, but probably out of reach forever.Since the 1990s, little progress has been made toward the goal to keep global temperatures from warming more than 2 degrees Celsius (3.6 degrees Fahrenheit), while the Qatar talks in December, fail to address growing greenhouse gas emissions, climate scientists said.

The existing uncertainties about how the climate will respond to specific strategies, are nothing compared with potential disaster caused by delay, said study researcher Joeri Rogelj of Switzerland’s Institute for Atmospheric and Climate Science in Zurich to LiveScience. “The most important factor for staying below 2 degrees C is the timing of when we start tackling this problem at a global scale.”

About Climate change Global Action Delay Scientists attempted to weigh the costs and benefits of climate-change strategies ranging from a carbon tax on emissions to requirements for sequestering carbon underground,  However, Rogelj and his colleagues quantified and ranked  the importance of the uncertainties that keep scientists from predicting exactly how the future of climate will unravel, such as geophysical-,social-, technological-  and political uncertainties. The political uncertainty of ‘when will the world decide to act to prevent further warming ‘ dominated all other. If humanity delays in taking action, chances to stay below 2 degrees C become very low no matter how much money we throw at the problem in the future,” Rogelj said. About Climate change Global Action Delay “A delay of two decades in drastically reducing energy demands, will mean only a 20 percent chance of staying below 2 degrees” C, Rogelj said.

The researchers found that, if carbon emissions were immediately taxed at $40 a metric ton, there would be an 80 percent chance of staying below 2 degrees in an energy-efficient world. A low-energy future has upsides beyond climate mitigation, Rogelj said.”If one can continue to prosper in the future and deliver the same services with less overall energy, this will in the first place save you money, but also very significantly improve your national energy security situation,” he said. “It seems to me that such benefits should be appealing to any decision-maker who cares about the long-term development and prosperity of his or her country.”

Even though the study examined more than 700 future climate scenarios, the research didn’t take into account neither the cost of disasters such as coastal flooding if climate change is not mitigated, nor did it consider “runaway climate change” scenarios, i.e. the melting of the permafrost releases trapped methane stores into the atmosphere, that could send temperatures soaring faster than expected.Steve Hatfield-Dodds of Australian National University, who was not involved in the study, finds the researchers’ predictions for economic growth and population growth “somewhat optimistic”, which makes estimated likelihoods of climate-mitigation success also optimistic, Nevertheless, “the findings should help to make risks and consequences more transparent, and thereby support better-informed economic and political decisions,” Hatfield-Dodds wrote.
