Short essay on Global Warming
Global warming refers to the gradual increment of the average temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases like Carbon dioxide, Methane, Nitrous oxide, Ozone etc. These spread their arms over the earth’s atmosphere through burning fossil fuels, deforestation and Arial pollution.
According to UN report, the atmospheric temperature has risen by 1.10 F and the sea level has risen several inches. Data also reveal that if it continues to increase at the current rate, the temperature would likely reach 1.50C in a few years.
The major devasting effects include the melting of glaciers, rising sea levels, altering precipitation, changing water supplies and many more. India will be among the worst-hit countries that may face the wrath of calamities like floods, heatwaves and reduced GDP. Indian metrological department said 2018 was the sixth warmest year on record.
To fight against global warming, the whole world came under one roof as the Kyoto protocol committed to cutting down the emission of GHGs. They started to adopt renewable and non-conventional energy sources. Against global warming India needs to be both innovative and forward-looking. To promote non-conventional sources, India has set ambitious targets for wind and solar power. Moreover, Budget 2019 contained a path-breaking initiative to provide a personal income tax benefit for investment in electric vehicles that also make perfect sense against global warming.
However, these are not enough. We need to take many strict actions as the pace of global warming is accelerating and if we are late then the opportunity to reverse the damage will disappear.

“Co-operate or Perish” – UN Secretary-General Antonio Guterres.
Recently, UN Secretary-general Mr Antonio Guterres rightly said that the world has two options. First, co-operate in reducing carbon emissions to fight climate change and second, perish in Climate caused disasters.”
Since Industrialisation, Global temperature has been increasing due to large-scale CO2 being one of the largest greenhouse gases, which increases global temperature due to the greenhouse effect.
The intergovernmental panel for climate change (UNCC) is an UN-recognized scientific body to study climate change and its effects. It recently reported that climate change had caused severe irreversible damage to the earth. If it is not controlled, there will be severe negative consequences for human beings and the earth’s biodiversity.
Various multination bodies are made to address this issue, such as UNFCCC and the annual conference of parties meetings to negotiate for a reduction of carbon emission, climate financing, adaptation, mitigation and lifestyle change.
In COP-21, it was decided that global temperature will be kept below 2 degrees centigrade or ideally below 1.5C upto the end of the 21st century. In COP-26 (which occurred in Glasgow), It was decided that the Developed nation (a significant contributor to climate change) would provide climate financing to the developing nation to help them adopt renewable energy technology.
n the recent COP-27 (which occurred in Egypt), India showed the world its new path for development, i.e. LTLEDS (long-term low emission Development strategy). Under this plan, India will try to mitigate Carbon emissions through the following steps. It was first, Making India a global hub for green hydrogen energy and second, Multiplying nuclear energy capacity by threefold upto 2032.
Third, E-20, i.e. 20% ethanol blending in petrol upto 2025 to reduce carbon emissions. Besides these, India has other aspirational goals, such as achieving Net-zero emissions upto 2070, using renewable energy to complete 50% of National energy demand upto 2030 and generating the capacity of 500 GW of energy capacity through non-fossil energy upto 2030.
2/3 of total greenhouse emission is generated by household consumption. That is why our hon’ble Prime minister Shri Narendra Modi gave the concept of Green-Lifestyle. Under this, people will have green choices in their daily life. Green choices include:
- Saving energy in homes.
- Using public transport.
- Using cycles.
- Practising the concept of reduce, reuse and recycle.
- Reducing wastage of food and creating dedicated pathways to encourage cycling.
He also emphasized that as the Climate changes, crops will fail due to very high temperatures and water scarcity. Hence it is essential to diversify the crops with enduring crops such as millet, oil seeds, cotton etc. That is why 2023 is celebrated as the International year of millet.
Hence it is essential to work on carbon mitigation, climate financing (by a developed nation to a developing nation), adoption (Renewable energy) and carbon capturing technology.
It is rightly said that the cost to achieve net zero emissions is a fraction of the high cost required to adapt to an unlivable planet. That is why it is the right time to work together and survive, or all will perish forever.
