New York. A new report by the United Nations Intergovernmental Panel on Climate Change (IPCC) on climate change was published on Monday. It has been warned about the rising global temperature. It has been claimed in the report that the heat wave (severe heat), which comes once in every 50 years, is now coming every 10 years. Along with this, heavy rains and drought have started falling every decade. According to the IPCC report, more than 200 authors from 60 countries have concluded that the global temperature will rise by 1.5 degrees in the next 20 years, looking at five conditions.
Scientists have said that if we fail to take action, many changes seen in the climate will destroy our future. Such facts have been presented in the report, in view of which there is a need to handle in time. In addition, the report states that some changes are already in motion, such as sustained rise in sea level, that are irreversible over hundreds to thousands of years.
This worrying announcement has been made in the latest Intergovernmental Panel on Climate Change (IPCC) report released at a virtual global media conference held in Geneva. IPCC’s Sixth Assessment Report (AR6) Climate Change 2021: The Physical Science Basis has been released. This is the first installment of the report, which will be completed in 2022.
The report’s more than 200 authors look at five scenarios, and the report says that in any case, the world will exceed the 1.5°C temperature mark in the 2030s, well ahead of old forecasts. Three of those scenarios will see an increase of more than two degrees Celsius above the pre-industrial average temperature.
The report shows that emissions of greenhouse gases from human activities are responsible for approximately 1.1 °C of warming since 1850–1900, and that the average global temperature is expected to reach or exceed 1.5 °C over the next 20 years. are supposed to.
The assessment is based on improved observational datasets to assess historical warming, as well as advances in scientific understanding of the climate system’s response to human-caused greenhouse gas emissions, an IPCC statement said. If we look at the key points of the report, it has been warned that climate change is accelerating the water cycle. It is also causing more intense rainfall and associated flooding as well as more intense droughts in many areas.
In addition, climate change is affecting rainfall patterns. In higher latitudes, rainfall is likely to increase, while it is expected to decrease over large parts of the subtropics. Changes in monsoon rainfall are expected, which will vary by region. (with agency input)
