Climate Change

Climate change is already impacting every corner of the world, and much more severe impacts are in store if we fail to halve greenhouse gas emissions this decade and immediately scale up adaptation.    

Climate change affects everything from geopolitics to economies to migration.

Climate change is also harming species and whole ecosystems. Climate change is already causing widespread disruption in every region in the world with just 1.1 degrees C.

Climate change may affect the production of maize (corn) and wheat as early as 2030 under a high greenhouse gas emissions scenario, according to a new NASA study published in the journal, Nature Food. Maize crop yields are projected to decline 24%, while wheat could potentially see growth of about 17%.



Using advanced climate and agricultural models, scientists found that the change in yields is due to projected increases in temperature, shifts in rainfall patterns, and elevated surface carbon dioxide concentrations from human-caused greenhouse gas emissions. These changes would make it more difficult to grow maize in the tropics.


Methodology

Climate change reverses progress towards sustainable development and peace, posing risks to human security and making peace harder to achieve. Both slow onset changes such as temperature rise, ocean acidification and changes in precipitation patterns, as well as fast onset events such as storms and floods can have an effect on economic and political security, and on the security of a particular community’s food, health and environment.

Policy- and decision-makers in multiple sectors, especially development, diplomacy and defence, have sought ways to predict and respond to these impacts. However, in order to do so effectively and sustainably, the complexity of different factors and interactions has to be unpacked into a granular understanding of the relationship between environmental change and insecurity in a given context. For awareness of the risks to be converted into action that improves lives, concrete entry points need to be identified.

This is where the Weathering Risk methodology comes in.

There are five steps 

  1. Step 1: Map the impacts of climate change  
  2. Step 2: Analyse vulnerability and resilience
  3. Step 3: Identify and test scenarios
  4. Step 4: Analyse the data with machine learning
  5. Step 5: What are the options?

As per Nasa - “We did not expect to see such a fundamental shift, as compared to crop yield projections from  previous generation of climate and crop models conducted in 2014,” said lead author Jonas Jägermeyr, a crop modeler and climate scientist at NASA’s Goddard Institute for Space Studies (GISS) and The Earth Institute at Columbia University in New York City. The projected maize response was surprisingly large and negative, he said. “A 20% decrease from current production levels could have severe implications worldwide.” 

Statement by Prime Minister Shri Narendra Modi at COP26 Summit in Glasgow

I would like to draw your attention to one more important topic. Today, the world admits that lifestyle has a big role in climate change. So, I propose before you a One-Word Movement.h

This One-Word , in the context of climate, can become the basic foundation of One World. This word is- LIFE...L, I, F, E, which means Lifestyle For Environment. Today, there is a need for all of us to come together and take Lifestyle For Environment (LIFE).


The Government of India launched National Action Plan on Climate Change (NAPCC) on 30thJune, 2008 outlining eight National Missions on climate change. These include:


  1. National Solar Mission
  2. National Mission for Enhanced Energy Efficiency
  3. National Mission on Sustainable Habitat
  4. National Water Mission
  5. National Mission for Sustaining the Himalayan Eco-system
  6. National Mission for a Green India
  7. National Mission for Sustainable Agriculture
  8. National Mission on Strategic Knowledge for Climate Change


Solution Approaches:

  • Systematic survey of greenhouse gas (GHG) 
  • Energy audits
  • Analysis and implementation of renewable energy plants 
  • CO2 neutrality
  • Off-setting measures 
  • Commitment within the scope of Science Based Targets
