Global warming

What is global warming ?    

Global warming is the continuous hike in the average temperature of the earth. In the last  50 year, the average global temperature has hiked at a rapid seep in recorded history.
                          
 In 2019, the global average temperature on land and in ocean was 1.75 degrees F exceeding the 20th-century average. Making the year 2019 second hottest year on record, falling behind 2016 only.
                      
 The hike in heat is caused due to the human activity.
By burning of fossil fuels the greenhouse gases are released into the atmosphere, which catches heat from the sun and heats up surface and air temperatures.

What causes global warming ?

                    
  Global warming take places when carbon dioxide and more air contaminants and greenhouse gases accumulates in the atmosphere and absorb sunlight and solar radiation that have reflected towards the earth's surface. Usually, this radiation fades away into space, but these contiminant, which can last up to years to centuries in the atmosphere catches the heat and causes the planet to gets hotter. This is well known as the greenhouse effect.

In India, the burning of fossil fuels to generate electricity is the huge contributer in heat trapping pollution, generates about millions of tons CO2 ever year. Coal burning power plants is the biggest polluters in India. Another biggest polluter is transportation sector.

Restricting dangerous climate change needs extremely deep slash in emissions and the use of other alternatives to fossil fuels worldwide. The good news is that in India we've started using energy efficient technology and cleaner fuel.

How is global warming associated with extreme weather ?

Scientists admits that the temperature of earth is warming up for a long ago and is giving rise to more heat waves, heavy rainfall, frequent drought and powerful hurricanes.

The temperature of oceans are becoming warmer, that means the tropical stroms can carry more power. So the global warming can turn, the level 3 storm into a more dengerous level 4 storm. 

The effect of global warming is being experienced around the globe. Extreme heat waves have killed ten's of thousands of people around the globe in the recent years. An alarming sign of phenomena to come. Antarctica is losing around 134 billion metric tons of ice every year since 2002. The rate could be accelerate up if the fossil fuels are burnt at same speed. Some experts say that it can cause sea levels to rise that may sink some of the biggest cities of the world. 

What are the other consequence of global warming ?

Every year, scientists learn more about the effect of global warming and many accept that environmental, health and economic effect are probably to happen if ongoing trends continues. Here is smattring to look forward =

• Melting glaciers, early snowfall and severe drought will give rise to more dramatic water scarcity and enhance the  threat of wildfires.

• Rising sea levels will cause the coastal flooding in some of the important cities.

• The forests, farms and cities will face difficulty with new virus, heat waves, heavy drift and increased flooding. All these aspects will damage and shatter agriculture and fisheries.

• Disintegration of coral reefs and alpine grassland can turn many plants and animal species to go extinction.


• Allergy, asthma and other contiguous disease outbreaks will become more usual due to increased pollen production higher levels of air pollution and the spread of compatible conditions for pathogens and mosquitoes.

Where does the India stands in terms of global warming contributors ?

China has been the biggest contributors in global warming pollution, producing up to 30% of all CO² emissions. The India comes in fourth. India produce only 7% of all global CO² emissions.

Is India doing anything to stop the global warming ?

India has started to develop a long term paln strategies that will help in lower the levels of carbon dioxide and other greenhouse gases. Under the Paris agreement it will increase its climate pledges, or nationally determined contributions (NDCs).

In the first round of national climate action plan presented by India in the year 2015 under the Paris agreement set targets that will have to be attained by 2030. India laid three important targets to be attained by for the time between 2020 and 2030. Rise in the share of non fossil fuels to 40% of the overall electricity generation capacity, to decrease the emission intensity of the economy by 33 to 35% by 2030 from 2005 levels and to create further carbon sink of 3 billion tonnes of CO² equivalent via additional forest and tree cover. 

India have attained reducing energy intensity by 25% and already 78GW of renewable energy has been made achievable. At the same period forest cover has grown by about 15,000sqkm and tree cover outside the forest is growing quickly.
