The city is a global warming hotspot because this trap is hot, and there is a shortage of cooling areas such as water and vegetation.
The UN government panel about climate change, where India is one of the 195 members, has released the current sixth assessment report. Scientists observe climate change in every region and throughout the climate system. Some changes that have been arranged – such as sustainable sea-level rise – cannot be recovered for hundreds to thousands of years.
But drastic and fast cuts in carbon dioxide and other greenhouse gases can limit climate change, but nations must agree to do this. Even if some magical countries agreed, when they met at Glasgow, England, at the end of this year, with blunt cuts, drastically, it could take 20-30 years to see a stable global temperature even though the benefits for air quality will come quickly. UN Secretary-General Antonio Guterres said the IPCC assessment – the most detailed review of climate science ever done – “Red Code for Humanity”.
Here are 10 points from the IPCC Climate Change Report:
1. The world warms faster. According to a bomb report, global warming is on track to reach 1.5 degrees Celsius to around 2030, a decade earlier than projected in 2018.
2. The sea level rises faster. The average level between 1901-1971 is 1.3 mm / year. This is more than doubled to 3.7 mm/year between 2006-2018. The global average sea level increased 0.20 (0.15 to 0.25) M between 1901 and 2018.
3. Extreme heat (including heatwaves) has become more frequent and more intense in most land areas since the 1950s, while extreme cold (including cold waves) becomes less frequent and less severe.
4. Human-induced climate change is seen as the main driver of this change.
5. The city is a global warming hotspot because of this hot trap, and there is a shortage of cooling areas such as water and vegetation.
6. Once 10 years and once in 50 years of hot, heavy rain and drought will become more frequent and intense.
7. Extreme weather events are more likely to be large, increasing frequency, new location, different time, new combination, i.e. Two or more extreme events occur together, heatwaves and droughts.
8. Although it is difficult to identify the proper causes of certain extreme events, based on cases per case, scientists can now measure the contribution of human influences on the magnitude and the probability of many extreme events.
9. Climate change and personal quality, two sides of the same coin. Overcoming both problems together can cause significant synergy and economic benefits.
10. Global warming can be limited at the end of this century but will cut drastically and directly – from now on, burning fossil fuels and other activities that emit greenhouse gases.
