Know what IPCC scientists say on increasing incidents of heavy rains and severe floods
In this monsoon, reports of floods after heavy rains are coming from many states including Maharashtra, Rajasthan, Madhya Pradesh, Bihar. Apart from this, you must have seen videos of landslides and cloudburst incidents in the hilly region i.e. Himachal Pradesh and Uttarakhand on social media. Not only this, California’s forests are still burning with fire, recently we also saw a scene of devastation after cloudburst in Japan and heavy rain in Germany. The Working Group-1 of the IPCC, which has studied all such natural phenomena in-depth, has released its report on Monday. It has been said in the report that the effects of heatwave i.e. hot winds are continuing across Asia including India. Not only this but the impact on many other areas of the world was also discussed in the report.
The Working Group-1 of the Sixth Assessment Cycle of the United Nations-affiliated Intergovernmental Panel for Climate Change (IPCC) completed its study on 6 August and released a report today. According to the report, since 1980, the process of heatwave ie warm winds rising from the sea has intensified, the biggest reason behind which is the activities of mankind. The special thing is that the most effective of these hot winds have been seen since 2006.
The fifth assessment of the IPCC also cautioned that the heatwave caused unusual changes in the weather. The fifth cycle report was released in 2014. It was clearly said in that report that in many countries of the world, the impact of cloudbursts, heavy rains at one place, drought, extreme heat, and cyclones on the beaches will be greater than before.
To be honest, over the years, this is exactly what the IPCC scientists said in 2014. Talking about India, after heavy rains in Chennai in 2015, the scene of devastation was very frightening. No one can forget the Kerala floods in 2018. Moreover, no one can forget cyclone Vayu and Fani in 2019, Nisarga in 2020, and then Amfan. The special thing is that if you look closely at the cyclones from 2013’s Phalin to 2021’s Amphan, you will find that the intensity of cyclones arising from the Indian Ocean, Bay of Bengal, or the Arabian Sea is increasing continuously. And we all know that the higher the intensity, the greater the damage.
Talking about the glaciers on the mountain, in February this year in Chamoli district of Uttarakhand, when a large part of the mountain broke with the glacier, the water level of Rishiganga and Dhauliganga rivers increased rapidly and many areas of Chamoli district were submerged. 83 people died in this incident of the breakup of Nanda Devi Glacier.
The first group of the IPCC has once again warned of the challenges ahead. A report released today titled “Climate Change 2021: The Physical Science Basis” states that such events across Asia will now be more intense than ever before.
A special note in the report on the intensity of heatwave and cyclone
The effect of hot winds has started increasing in most parts of the earth and will continue to grow. This effect will be visible in North America, Europe, Australia, Latin America, west and southeast parts of Africa, Russia, Siberia, and all of Asia. In some of these places, temperatures are likely to be much warmer than in previous years.
The northeast of South Africa, the Mediterranean, southern Australia, the western part of North America, where there was a little drought so far, maybe hit by drought in the coming times.
Northern Europe, North America, and Southern Africa will receive heavy rains in the next few years. Scientists said that more data would be needed to estimate rainfall in Asia, America, and other places.
What is the temperature target of the Paris Agreement?
According to scientists, by the end of this century, the average temperature of the Earth will increase by 2 degrees Celsius. If this happens, then the entire earth will be headed for destruction. To stop this increase, all the member countries of the United Nations have signed the Paris Agreement, whose main goal is to stop the increase in temperature by 1.5 Celsius. To stop this, carbon emissions will have to be brought down to zero. The level of carbon dioxide and other greenhouse gases will have to be stopped from increasing.
Scientists associated with the IPCC say that if we are successful in reducing emissions to the lowest level, then by the end of this century we can limit the increase to 1.5 degrees. However, between 2021 and 2040, there will be a much higher increase in temperature than before, after that the temperature will start decreasing. Such is the estimate of scientists.
Experts say G20 countries need to change gear
The United Nations High Commissioner for Climate Action and Finance, Mark Carney, has said on this report of the IPCC that the things that scientists have mentioned in this report are really worrying. Now the day has come when the governments of all countries have to keep in mind the advice of scientists before taking any major decision, before making policies, or taking financial decisions. The IPCC report needs to be read seriously by policymakers. Necessary steps need to be taken immediately to curb carbon emissions.
On the other hand, ICCCAD Director and IIED Senior Associate Prof. Salim-ul-Haq said that this IPCC report has burst the balloon of claims to save the environment, which governments of all countries have done. Now is the time when the G20 countries need to change gears. Now they need to reiterate their resolve and follow through on what they have taken for the earth. Running away from the advice of environmental scientists is like committing suicide because what they are saying is completely crystal clear and we are also seeing the effects of rising temperatures.
