The world faces a dangerous moment due to climatic change, though media in India is not focused on it. The US has gone back on its commitment to help reduce global warming. The Paris Agreement was signed in 2015, in which nations agreed to lower the carbon dioxide emissions. This was to be done by voluntarily cutting fuels and shifting to solar and wind energy.
Climate change is happening as a result of man-made global warming. Since 1880, the Earth’s surface temperature has risen at an average pace of 0.07°C every decade. This has resulted in a net warming of 0.95°C as of now. Land temperatures have risen faster than ocean temperatures so far. But this will change by 2030 unless the world’s nations cut their emissions. And once the oceans start to warm up, many countries will quickly be in deep trouble.
Heat in South Asia could exceed the survivable levels by the year 2100 says study.
Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.
Climatic change in India:
Indians will be vulnerable due to this climatic change in many ways:
Climate change will mean higher oceans and this will lead to huge problems in coastal cities like Mumbai, Chennai and Kolkata; it will also mean the monsoons become much more volatile and unpredictable. This will bring misery down on the Indian farmer.
Rising carbon dioxide levels from global warming will drastically reduce the amount of protein in staple crops like rice and wheat, leaving vulnerable populations at risk of growth stunting and early death.

Researchers say they still don’t understand how or why carbon dioxide emissions sap protein and other nutrients from plants, but the mystery is one that could have devastating consequences across the globe.
An additional, 150 million people globally may be at risk of protein deficiency by 2050 because of rising levels of carbon dioxide in the atmosphere said the report in the journal Environmental Research Letters.
Southern India may witness a decline in rice yields by five per cent in 2030s.
On August 3rd Tamil newspaper Dhinathandhi posted that in 2100 people survival in India will be hard due to heatwaves.
Heatwaves are already a major risk in South Asia, with a severe episode in 2015 leading to 3,500 deaths. India recorded its hottest ever day in 2016 when the temperature in the city of Phalodi, Rajasthan, hit 51C. According to new research that examines the toll rising temperatures are already taking on vulnerable societies.
Extreme heatwaves that kill even healthy people within hours will strike parts of the Indian subcontinent unless global carbon emissions are cut sharply and soon. According to new research led by Eltahir, a professor of climate and hydrology at the Massachusetts of Institute of Technology (MIT) in the US.
The new analysis assesses the impact of climate change on the deadly combination of heat and humidity, measured as the “wet bulb” temperature (WBT). Once this reaches 35C, the human body cannot cool itself by sweating and even fit people sitting in the shade will die within six hours.
Distribution of maximum wet bulb temperature (WBT) from 1976-2005 (B), from 2071-2100 (C), from 2071-2100 (D). WBT of more than 31C is considered extremely dangerous and over 35C is fatal within hours. Photograph: Courtesy of AAAS
In 2015, India and Pakistan witnessed one of the severest heatwaves in history which killed over 3,500 people.
Cityrene’s contribution to this climatic change:
Cityrene builds smart sustainable house. We adopt these technologies to overcome these climatic changes:
1.Venting out of hot air
2.Geo thermal cooling
3.Heat reflective windows and paints
4.Using GFRG for constructing houses which make them cooler by 4 degrees
5.Reducing the humidity in air by using the air from water technology.
