the developed world is responsible for most of climate change situation today. Over 70% of the greenhouse gases emission was due to the developed countries, while India’s contribution is just 3%.

Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

How Can We Stop Global Warming?

1. Recycle more. The aim is to cut down the amount of carbon dioxide released in the environment.
2. Drive less.
3. Plant trees.
4. Switch to renewable energy.
5. Use energy-efficient devices.
6. Use less hot water.
7. Turn off electronic devices.
8. Spread awareness.

The United States produced 6.6 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2019, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person.

In 2019, China was the biggest emitter of fossil fuel carbon dioxide (CO2) emissions. With a share of almost 30 percent of the world’s total CO2 emissions that year, this was roughly twice the amount emitted by the second largest emitter the United States.

The Arctic, Africa, small islands and Asian megadeltas are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.

China

As per the report, the top most polluted city is Xinjiang in China followed by nine Indian cities. Ghaziabad is the second most polluted city in the world followed by Bulandshahar, Bisrakh Jalalpur, Noida, Greater Noida, Kanpur, Lucknow and Bhiwari.
