Why our Climate is Changing and Who is responsible for it?

    Climate Change And World Together With India.

First of all, we will have to know, what is climate change?

 Climate change is the change in weather pattern, which can be identified easily by using statical data or test, that remains or persists for a long period. or it can also be referred to any change in climate  over time, whether due to natural variability or as   a result of human activity---IPCC (Inter-Governmental panel on climate change.

 Climate change caused by increasing the number of greenhouse gases such as carbon dioxide, carbon monoxide, methane etc in the atmosphere
increasing population and human activities like urbanisation, industrialization, carbon-intensive use, development of modern mean of transport etc are the major sources of emission of greenhouse gases.
The depletion of forest and green cover, considered as natural 'carbon sink ' has further added to the concentration of greenhouse gases.



Major greenhouse gases and their contribution to the greenhouse effect.

  • H2O(g)------ 36-73%
  • CO2---------  9- 26%
  • CH4---------- 4-9%
  • O3 ------------3-7%  
Also in our's mind, a small question arise is that, what is the greenhouse effect?

The emission and absorption of radiation that warms the earth are often referred to as the greenhouse effect, it is because a  greenhouse works in the same way.
The greenhouse effect, combined with increasing levels of greenhouse gases (GHG) and resulting global warming, is expected to have a profound implication, according to most climate scientists.

Greenhouse effect prevents heat radiation from the earth, which leads to rising in the ocean and lands temperature and also Conc. of atmospheric  CO2 increased in many stats which few decades till 2016.
  The main source of GHG gases are :
  1. deforestation 
  2. transportation
  3. electricity generation
  4.  household, 
  5. urbanization 
  6. live stocks
  7. animal respiration 
  8. fossil combustion
  9. agriculture
  10. industrialization
and the impact of these gases on climate change has been achieving its position  :
 These  are a few consequences of climate change:
  • the temperature will be rise from 3-10 degree Fahrenheit over the next century
  • droughts and deforestation will be intensified
  • many flora and faunas, species will become extinct
  • wheat & rice production will be reduced by by15-30%   by the year 2050
  • many health & diseases problem will increase
  • sea level will rise
  • precipitation rate will affect
 so after passing through this situation,  we will have to take a quick decision to prevent form such issues



 Q1. How can we prevent climate change?

 here are the few points of this question:
  • the use of green energy will be helpful in many expects
  • increase plantation
  • stop deforestation 
  •  by making awareness of peoples
  • avoid polythene use and imply green products
  •  Make donation
  • make your home environment-friendly
  • educate the future generation about climate change
  • use green and energy-efficient transport

In this era, the greenhouse effect mainly caused in two ways

1. NATURALLY OCCURRING GREENHOUSE EFFECT (NOG)
2. HUMAN -ENHANCED GREENHOUSE EFFECT (HEG)

1.NOG-- Main points
a) Solar energy passes through the atmosphere and warms the earth.

b) And about 30% of energy is reflected back to space.

c) greenhouse gases in the atmosphere trap the remaining energy. The solar radiation is absorbed by the oceans, land and atmosphere. As they heat up, the ocean, land  and atmosphere release heat, which passes out of the atmosphere and into space


2. HEG-- Main points

a) Solar energy passes through the atmosphere and wars the earth


b) Increased levels of greenhouse gases caused by human activities, trap the sun's energy and warms the planet's surface above the normal temperature, causing significant climate change.


The equilibrium of emission and absorption of radiation makes the earth habitable, with an average temperature of about 60 degrees Fahrenheit (15 degrees Celsius according to NASA.

* Human activities have added greenhouse gases in the atmosphere, mainly through the deforestation & burning of fossil fuel.

+  emission of carbon dioxide is by burning of fossil fuel, deforestation and cement production



 if we look for GHG (greenhouse gases) emission for major economies

CO2 emissions, in million tons  European union -28 comes on top  followed by US, Japan, Russian Federation, Brazil, India & China respectively

Global Initiatives to reconcile  climate change

UN organised its 1st conference on the human environment in Stockholm in June 1972.
After the conference, united nation environment programme (UNEP) was installed up  and it continues to act as a global speedometer for action to protect the environment


The UN conference on development and environment are popularly known as earth summit held at Rio de Janeiro (Brazil) from 3 - 12 June 1992.
approximately 178 countries have taken part in this conference

Note:
Global solar alliance -it is one of the initiatives of India at CoP-21- Paris, leading to the alliance of nation and industry on a large scale of solar energy use in tropics and beyond, possessing 120 countries under this.


about 1 million medium and small enterprises (MSME) will be involved in ' zero defect zero effect scheme' to improve their quality, waste management, energy efficiency, enhance resource efficiency, use of renewable energy.

#CoP-21 -Paris conference
Paris talks call for post-2020 climate agreement under UNFCCC(United Nations Framework convention on climate change) with legal torque and applicable to all parties.
 COP calls for decarbonisation of the global economy
