Reports on global warming are not new all over the world today and events that contribute to climate change include the burning of fossil fuels to foster the growth of our economy. It has also been discovered that by 2100, the earth will be 15% warmer than it should. Also, the growth of indecision of disconsolate projections has been narrowed also. However, it is important to note that lots of climate models have been made so far and these models project that the amount of climate change in this century is the ones that support current observations.
Furthermore, the use of climate models is to project how much warming is taking place and what we should expect when there is an increase in the concentration of gases like CO2 ( Carbon dioxide) and other greenhouse gases in the atmosphere.
Recent research has affirmed that the uncertainty of global warming is narrow, which means that the future looks dire for us.
Climate researchers who have worked on global warming had already proposed that there is a 62% chance of the earth becoming warmer on average by more than 4 degrees Celsius if there are no policies or measures to control the emissions of greenhouse gases. With a recent climate study, the uncertainty of global warming has been narrowed and it is now estimated that by 2100, there will be a 93% chance that global warming will exceed 4 degrees Celsius.
Moreover, many nations of the world had a meeting in Paris in 2015 and they made a joint decision to curb the rise of global warming to well below 2 degrees Celsius; even at this temperature, the state of global warming can still pose a great danger to the earth. However, one degree higher to this temperature is cataclysmic. And an increase above 5 degrees Celsius could pose a total change to the world or may even end it.
It is also important to note that two United State researchers made a report in the journal Nature. They made use of several climate models for the projections which were proposed by the UN’s Intergovernmental Panel on Climate Change and they also aligned the reasons against some opinions that were made.
In the report also, a detailed look was done on the differences in seasonal and monthly climate, the utilization of energy, the emissions of greenhouse gases, and how they affect temperatures. Furthermore, there have also been some contentions about how accurate these climate models work and how they can be used to forecast the world’s climate in the next centuries to come. With this, it has been affirmed that the future looks dire for us if nothing is done on global warming.
A researcher from the Stanford University of California has said that with the results gotten by them, it does not make sense to discard the forecasts made on global warming probably due to the fact that the models used are imperfect in their imitation to the way the climate looks now.
More truths
Researchers from the Stanford University of California have proposed that they are trying to show that the faults of the climate model can be used to discard predictions that are not severe. They have also stated that their results which were gotten by them suggest that if the world is to achieve a total stabilization of global temperature, then there is a need for a drastic decrease in the emissions of greenhouse gases that were previously envisaged.
With these statements and affirmations, it has been known that the use of climate models are essential as the use of climate data itself and that the basis of uncertainty could be the effect of warming. This means that there will be more evaporation to a warmer earth; which implies that the warmth of the earth is captured in the atmosphere which could cause an increase in the radiation of the sun.
For many years now, lots of research have been done in order measure with accuracy, the links between the emissions of greenhouse gases from the combustion of coal, natural gas, and oil, and the change in the temperature of the earth.
Modest indication
A researcher in Carnegie by name Ken Caldeira has estimated the way in which Carbon dioxide causes global warming in the earth and the way in which greenhouse gases can warm the earth for a long period of time.
However, recent conclusions solely rely on modest indications which is the precision with which climate models can be used to envisage the future of the earth when it comes to climate change.
Ken Caldeira has praised the use of these models that simulate today’s comments and he has also said that these models may be the most reliable forecast for the future of the earth.
Finally, based on a recent research, it has been confirmed that if there are no adequate policies put in place concerning the emissions of greenhouse gases, there is a high chance that global warming will surpass 4 degrees Celsius by the end of this century, which indicates grave danger on the future of the earth.
