Human living on earth is in danger: UN report on global warming

Fires, floods, and extreme weather seem to be a foretaste for the grim situation the mother planet is expected to face in the future. On Monday, the Inter-governmental Panel on Climate Change (IPCC) warned that the average global temperature will likely rise by over 2 degrees Celsius by 2100.

The first part of its Sixth Assessment Report of the IPCC claimed that some of the changes such as rising sea level are already in motion that is said to be irreversible for hundreds to thousands of years. The report has wide acceptance as an authentic scientific assessment.

Scientists are observing changes in the Earth's climate in every region and across the whole climate system. Some of the changes already set in motion - such as continued sea-level rise - are irreversible over hundreds to thousands of years.

In the report, scientists warn that if not immediate action is taken by the governments across the globe to reduce the greenhouse gas emissions, the possibility of global temperature rising over two degrees Celsius is high and the subsequent events due to climate change are irreversible and inevitable. 

The IPCC, made up of hundreds of the world's foremost climate scientists, publishes comprehensive assessments every seven years, with this report being the sixth since 1988.

This one will be different, however: previous work has shown that the 2020s are a crucial decade, in which greenhouse gas emissions must be halved to limit heating to 1.5C above pre-industrial levels, established by previous IPCC reports as the threshold of safety, and the lower of two goals in the 2015 Paris agreement.

Scientists allude to recent fires in the US, and Brazil, heatwaves in northern latitudes, and devastating floods in China and Europe, warning that this may become the norm unless climate breakdown can be stopped.

The report suggests that even if very wide-ranging and ambitious cuts in greenhouse gas emissions are initiated immediately, the temperature rise was expected to cross 1.5 degrees Celsius, and reach 1.6 degrees Celsius, before being reined back to 1.5 degrees Celsius.
