New climate assessment reportDate: 02 March 2022 Tags: Reports & Indices
The second part of the Intergovernmental Panel on Climate Change (IPCC) report has been recently released.
The first part of the report, released in August last year, was centered on the scientific basis of climate change.
The IPCC reports are the most comprehensive evaluations of the state of the earth’s climate. They are prepared by climate scientists using detailed studies.
There is nothing remarkably unique. It has built on the work of the previous ones, adding more evidence, information and data.
Multiple climate change-induced disasters can occur in the next two decades even if strong action is taken to reduce the emissions of greenhouse gases.
India has been identified as one of the vulnerable hotspots. Several parts of the country are facing high risks due to climate change.
New study aspects
For the first time, it has made an assessment of regional and sectoral impacts of climate change. It has assessed risks for megacities around the world.
It has assessed granular data to provide a clearer picture. It is for the first time that such granular information has been studied.
For the first time, it has looked at health impact of climate change. In sub-tropical regions, climate change is increasing vector-borne and water-borne diseases like dengue and malaria.
Rise in temperature is likely to increase circulatory, respiratory, diabetic and infectious diseases, impacting human health.
Allergic diseases and mental disorders are increasing due to events like heatwaves, flooding, drought, and even air pollution.
The report says that if the threshold of 1.5 degree rise is broken, then many climate changes could be irreversible.
The steps taken to reverse carbon sequestration are not enough to make a turnaround. Lack of funds and political commitment were the main reasons for the shortcomings.
The studies can be used by countries to formulate their policy responses to climate change. The next steps of international climate negotiations are expected to be based on these reports.
