Change in climate can cause severe harm to humans, properties, and management. The main threat ocuuring from it is global warming driven by human emissions of greenhouse gases which further results in change in climate condition.
The climate change is a major problem of world by the following ways-
*1) Extreme Heat -* Change in climate causes extreme rise in temperature and cause heat. This cause bad impact on agriculture.
*2) Changing Rainfall Pattern -* A 2°C rise in the world’s average temperatures will make India’s summer monsoon highly unpredictable.
*3) Droughts -* Change in climate increases the possibilities of Droughts. Evaporation rates increases with the rise in climate change.
*4) Groundwater -* Agriculture of India is highly dependent on groundwater, but with the frequent rise in temperature, the groundwater level is depleting at faster rate.
*5) Melting of Glaciers -* Change in climate change and changing temperature leads to melting of Glaciers.
*6) Sea level rises -* Melting of Glaciers and change in rainfall pattern cause contribute to rise in Sea level.
*7) Health -* Climate change also causes bad effects on health like asthma, breathing problems, skin cancer etc.
*8) Migration and unstability -* Change in climate forces people move to a better place with moderate climate which many times effects development of a place further causing unstability.
There are many such more reasons like - it effects the agricultural and water pattern etc. It's serious concern. There are solutions to it like - sustainable development, using CNG and using public means of transport, using eletric vehicle and sustainable use of everything and also switching off lights when not in use.
*"Nature gives back to us what we give to it whether in a positive way or negative......."*

Climate change:

A change of climate in long term which is attributed to directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

Factors affecting climate change on world:

  1. Continental drift
  2. Variation in earth's orbit
  3. Plate tectonics
  4. Volcanic activity
  5. Ocean currents

Anthropogenic factors:

  1. Green house gases: Water vapor, CO2,CH4,NOx,CFCs.
  2. Atmospheric aerosols
  3. Land use change
  4. Ocean acidification

 

 

 

Effects of Climate change in India:

Surface temperature:

  • At the national level increase of -0.4 oc has been observed in surface air temperature over the post century.
  • A warming trend has been observed along the west coast, in Central India, the interior peninsula, and North -Eastern India.

Rainfall:

  • while the observed monsoon rainfall at the all India level does not show any significant trend, regional monsoon variations have been recorded.
  • A trend of increasing monsoon seasonal rainfall has been found along the west coast, northern AP, North western India (+10% to +12% of normal over 100 years).
  • While a trend has been observed that the decreasing monsoon seasonal rainfall over M.P, N.E India, some parts of Gujarat and Kerala (-6% to -8% ) .

Rise in sea level:

  • The Reports that rise sea level in the North Indian ocean is between 1.06 - 1.75 mm/year
  • Coastal states of Maharashtra, Goa & Gujarat face a grave risk from the sea level rise.

Impacts on Himalayan glaciers:

  • Glacial melt may impact their long term seasonal flows, with adverse impacts on the economy in terms of water availability and hydropower generation.

Impacts on Indian Biodiversity:

  • Temperature increases and human activities are causing fragmentation and degradation of mountain biodiversity.
  • There will be and increase in the phenomenon of the Glacial lake outbursts Floods (GLOFs) Causing catastrophic flooding downstream, with serious damage to life, property, forests , farms & infrastructure.
  • A recent example in Ladakh, (GLOF) hits Gya village in Ladakh destroying Houses, fields & bridges.

Impacts on Indian agriculture:

  • A large part of arable land in India is Rainfed. Not only the Agriculture will be adversely affected by variation of amounts of rainfall but also by shifts in the timing of the rainfall. 
  • And poses a threat to agriculture and therefore to economy and food security.

As per Inter-governmental panel on climate change(IPCC) special report on the impacts of rise in  global warming temperature 1.5 oc  above pre industrial levels and also to provide every nations to put forward adaptations and mitigation options which determines the state of knowledge on climate change. In India certain measures like National Action plan on Climate Change (NAPCC) and 8 National missions which aims at awareness among the representatives of all public, private and the whole community to cooperate in all efforts at climate change mitigation.

Climate change is a serious issue that our contemporary world in witnessing today. According to IPCC our temperature has risen from 2.5 degree Celsius to 4 degree Celsius and it will further increase in future.

Global effect:

  • Global warming: Heating of the earth surface more than a specific temperature
  • Melting of glaciers 
  • Seal level rise
  • Disappearance of polar region
  • Variation in temperature and precipitation
  • Affecting whole ecosystem and changing range of flora and fauna
  • Lengthening of frost-free period 
  • Longer and high intensity heat waves that lead to hurricanes with intensive storms
  • Leads to unpredicted flood and droughts.

Climate change affecting Indian regions

Effect:

  • Melting of ice in Himalayan ranges 
  • Changes in monsoon in southern region 
  • Flooding in ganga Brahmaputra and Indus regions
  • Unpredicted storms and flood in coastal regions (eastern and western coast).
  • Intrusion of sea water to fresh water contaminating the fresh water sources and affecting soil quality of areas.
  • Regions change to hot islands
  • Changes in weather pattern, hot days are hotter and cold days are colder

Result:

  • Poses a threat to agriculture  
  • Raises food security issues that leads to migration to conflict
  • Health of people are in stake 
  • Demand for import of food product increases
  • Disturbs distribution of ecology
  • Impacts the existence of vegetations and animals.

Hence, we can conclude that climate change is a serious issue that has to be curbed for the betterment of our future life. We may not be the first generation to realize that what we are doing are all causes for the climate change but let us try to be the generation who has contributed best to combat the dreadful issue and done something to secure our planet earth.

Climate Change is a change in average condition such as temperature and rainfall in a region over a long period of time.
There are many natural and anthropogenic activities causing threat to the environment resulting in global climate change.

Global effect:

 • Global warming: Heating of the earth surface more than a specific temperature
 • Melting of glaciers
 • Seal level rise
 • Disappearance of polar region
 • Variation in temperature and precipitation
 • Affecting whole ecosystem and changing range of flora and fauna
 • Lengthening of frost-free period
 • Longer and high intensity heat waves that lead to hurricanes with intensive storms
 • Leads to unpredicted flood and droughts

Climate Change in INDIAN REGIONS

 • Melting of ice in Himalayan ranges
 • Changes in monsoon in southern region
 • Flooding in ganga Brahmaputra and Indus regions
 • Unpredicted storms and flood in coastal regions (eastern and western coast).
 • Intrusion of sea water to fresh water contaminating the fresh water sources and affecting soil quality of areas.
 • Regions change to hot islands
 • Changes in weather pattern, hot days are hotter and cold days are colder.

Warning against rapid climate change, India’s first-ever climate change assessment report has revealed that the country’s average temperature is expected to rise by 4.4 degree Celsius by the end of the year 2100.

Tackling climate change requires action at all levels of society, from individuals and educators to policymakers and businesses. By fostering awareness, capacity building and innovation climate change learning helps communities and individuals to reduce greenhouse gas emissions and effectively adapt to the changing climate.
