The IPCC and the increasing concerns of Climate Change

Date:

The Intergovernmental Panel on Climate Change report, released on 9th August 2021, explained the changes observed in Earth’s climate in every region and across the whole climate system.

Many unprecedented changes took place, and many disastrous changes are moving ahead with pace. The continued rise in sea level is one of the most concerning. These changes are irreversible over thousands of years.

Although the IPCC’s Working Group I report proposed that reducing carbon dioxide and other greenhouse gases can limit changes in the climate, it also exclaimed that it could take 20 to 30 years to see global temperature stabilize. 

The Working Group I Report  

The IPCC’s Sixth Assessment Report (AR6), completed in 2022, its first instalment is The Working Group I Report, Climate Change 2021: The Physical Science Basis.

One hundred ninety-five member governments approved the Working Group I Report of IPCC. There was a virtual approval session held over two weeks starting from 26th July. 

The Chair of the IPCC, Hoesung Lee, explained that this report reflects extraordinary efforts under exceptional circumstances.

The transformations described in this report, and advances in climate science that it reflects, provide crucial input into climate negotiations and decision making. 

The Working I Report addresses the most recent activities towards climate change. It focuses on explaining the impact of human beings on a broader range of climate characteristics, including extreme events.

The report mentioned the advances in climate science, understanding the processes, combining multiple lines of evidence from Paleoclimate and global and regional climate simulations. It has also mentioned climate risk assessments. 

The Increasing Rates of Global Warming 

According to the report, there are far higher chances of crossing the global warming level of 1.5°C in the following decades.

The report shows concern that unless there are quick large-scale reductions in the greenhouse emissions, limiting global warming to close to 1.5°C or even two °C will be beyond reach.  

The IPCC’s Co-Chair Valérie Masson-Delmotte mentioned that the report is a reality check. He said that we now have a comprehensible picture of the past, present, and future climate, which is essential for understanding in what direction we are going ahead, what we can do to make conditions better, and how we can prepare for what’s coming soon. 

The report shows that approximately 1.1°C of warming since 1850-1900 is due to the emissions of greenhouse gases from human activities and finds that global temperature is anticipated to surpass 1.5°C of warming over the next 20 years. 

The Human Influence  

The report proposes that human actions still can determine the future course of climate.  

Masson-Delmotte proposed that It has been clear for decades that the Earth’s climate is changing, and the role of human influence on the climate system is unquestioned. 

If the Global Warming level reaches beyond 1.5°C, there will be more extreme conditions on the planet. Longer warm and shorter cold seasons will be heatwaves and extreme heat conditions, affecting health and agriculture.

But the increasing rate of climate change will influence the temperature of the planet; there are more critical consequences.

The water cycle will be highly impacted, and there will be high rainfalls in some places and extreme droughts in other regions.

Coastal areas will experience a high frequency of floods due to continuous increases in the sea level.  

The Sixth Assessment Report provides a clear idea of the situation and the potential solutions for the near future with risk assessment and adaptation strategies taken into account.

It gives a new framework for translating the physical changes into climate – into what they mean for ecosystems.
