According to a report from United Nations, countries all over the world need to devise innovative ways to reduce carbon emissions and limit energy demand in order to meet the goal of capping global warming at 1.5 degree Celsius, set by the Paris Agreement on Climate Change.
The 1000-page report written by hundreds of scientists also states that it is very unlikely that the goal will be achieved by the end of the century. Current emission trajectories put us under the risk of global warming to rise and if this trend goes on, the earth will get hotter by 1.5 Celsius by 2040.
The report concluded that there are no models that can devise a 66% or more chances of reducing global temperature by 1.5 degrees Celsius.
Rise in global temperature by 1 degree Celsius has created a turmoil for our planet and we’re going through intense climatic impacts leading to unpredictable natural disasters.
All the countries made voluntary pledges to cut down carbon emission and the Intergovernmental Panel for Climate Change (IPCC) led by United Nations mandated to prepare a 1.5 C report that covers the impacts and feasibility. The final version of the report is scheduled to be unveiled in October.
Some nations will be affected more than others by the rise in global warming. Island nations like Bangladesh and Vietnam could be wiped out of existence because of rising sea levels.
Drawing CO2 out of the atmosphere and converting it to another form or storing it underground to use as fuel could be few of the ways we could achieve the goal. However, no existing technology is capable of doing it on a large scale as of now and improving current technologies to achieve the 1.5° C target can cause unforeseen circumstances.
CO2 emissions must fall to zero by 2050 to make this a reality and that would mean that any amount of CO2 released into the air would be hazardous. Emission of greenhouse gases such as methane and HFCs have to be reduced to zero. We must give up on coal and make sure that renewable energy sources like solar and wind will be the only ones to rely on.
Government officials will be submitting their reviews in the current review cycle and it’ll be finally approved after a discussion between governments and the scientists who wrote the report.
