Experts are claiming that controlling global warming by keeping the global average temperature rise at 2°C might not be enough.
Tschakert, who is a member of the IPCC (Intergovernmental Panel on Climate Change), has said that the current global target for temperature rise will not be enough for saving species who are at highest risk of succumbing to climate change.
This subject was discussed for two days at the Lima Conference of the Parties; experts talked about the possible consequences of keeping a temperature rise of 2°C as the average global warming target.
Charles Kennel and David Victor, two climate analysts from the United States, called the current global warming target politically unachievable and scientifically meaningless.
However, now the biggest call has been taken by Petra Tschakert, a climate expert representing the Penn State University of University Park. Tschakert has been operating as a member of the review committee set up by the United Nations for analyzing the target and taking decisions. So, when she calls something inadequate the UN bosses will have to listen.
According to Tschakert, the target should be brought down to 1.5°C. She believes that for limiting the rise in sea level to less than 1 m, for ensuring that the Arctic region has some ice left in it even during the summer months and for protecting 50 percent of the coral reefs, lowering the target to 1.5°C is necessary.
The target of 1.5°C has received huge support from climate experts around the globe. As mentioned above, the matter was discussed at the climate conference held in Lima, Peru in December 2014.
The entire review will be published around June this year. Reports are suggesting that the change in target might be made official during the Paris climate negotiations to be held in December 2015.
Although it is believed that the new target will help in controlling global warming better, many are still saying that like the target of 2°C, the target of 1.5°C is also just an arbitrary threshold. So, we’ll have to wait to find out what kind of results this change brings in.
