According to experts, the control of global warming by maintaining the global average temperature rise at 2°C may not suffice after all.
A member of the IPCC (Intergovernmental Panel on Climate Change), Petra Tschakert said that the existing global target for temperature rise will not be adequate for protecting the species that are at its highest risk of succumbing to climate change.
This issue has undergone serious discussion for two days at the Lima Conference of the Parties. Scientists have discussed about the plausible consequences of maintaining a temperature rise of 2°C as the average target for global warming.
Two climate analysts of United States, David Victor and Charles Kennel called this current temperature target of global warming unattainable from a political perspective and scientifically pointless one.
Nonetheless, the biggest call had been taken by Tschakert, a climate expert representative of the Penn State University of University Park. Tschakert is serving as a member of the review committee set up by United Nations for the purpose of analysis and evaluation of the target and making decisions. Therefore, when she refers to this situation as ‘not enough’ then UN officials have to pay attention to it.
Tschakert firmly believes that the target has to be brought down to 1.5°C and also considers that limiting the rise in sea level to lower than 1 meter is vital for making certain that the Arctic region has some ice remaining in it in the course of summer. The protection of 50% of the coral reefs also calls for lowering the target to 1.5°C.
This newly set target of 1.5°C has been receiving huge support from climate experts all over the world, when discussed at the climate conference that had been held in Lima, Peru in December 2014.
The complete review will be released in June and reports suggest that change will be set out to be declared officially in the Paris climate negotiations scheduled for December 2015.
It is strongly believed that this new target will aid to control global warming much better even though many are saying that like the previous target of 2°C this new 1.5°C is also subjective.
