At present, out of the top five most pressing global and local environmental challenges, ‘Climate Change’ features at the top.

It has been broadly defined as, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” 

The impact of Climate Change’ is so profound that, if not addressed immediately, it would most likely to cause extinction of human life from the planet Earth and that too in the most agonizing and painful way, lasting over a long period of time.

The Paris Summit and its objectives: 

To effectively address the ‘Climate Change’ issue, nearly 150 world leaders of 196 countries, including Prime Minister Modi, deliberated in the Paris summit earlier in December 2015. Their representatives and negotiators ultimately succeeded, at the fag end of the ‘Paris Summit’ to arrive at a global consensus for inking a new ‘Climate Change’ agreement.

Prior to this, a report titled, “Paris 2015: Getting a global agreement on climate change”, published in August, 2014 by the Green Alliance Trust, United Kingdom stated that the agreement, expected to be signed in this Paris summit should ensure a meaningful united global action on climate change, covering the following key points:

• A strong legal framework and clear rules
• A central role for equity
• A long term approach
• Public finance for adaptation and the low carbon transition
• A framework for action on deforestation and land use

Experts opined that a strong deal will make a significant difference to the ability of individual countries to tackle climate change by ensuring the following:

• Give a clear signal to business for desired environmental protection and pollution control
• Guide investment toward low carbon outcomes
• Create a simpler, more predictable framework for companies operating in different countries
• Help meeting international development aims, which are at increasing risk from rising global temperatures.
• Help reducing poverty
• Help improving health and building security
• Fetch huge benefits to the natural environment by helping to avoid biodiversity loss and the degradation of ecosystems upon which the existence of human life depends

India’s position on ‘Climate Change’:

India’s position on ‘Climate Change’ has been clear and is well captured in Prime Minister Modi’s reiteration in the Paris summit as follows:

“Climate change is not of our making. It is the result of global warming that came from an industrial age powered by fossil fuel. Yet, we face its consequences today, and that is why the outcome in Paris is so important and we are here today. We want the world to act with urgency. Agreement must lead us to restore balance between humanity and nature. We want a comprehensive equitable and durable agreement in Paris.”

Worsening health effect:

‘Climate Change’ could even drive the human race to extinction in its final outcome. Meanwhile, besides its devastated environmental impact on the planet Earth, it would gradually but surely worsen human health conditions.

In this article, I shall focus only on human health perspective on ‘Climate Change’. 

Direct and indirect health impact:

I would classify the adverse impact of ‘Climate Change’ on health basically into two categories:

- Indirect

- Direct

Indirect impact: 

Many of the indirect health impact events of ‘Climate Change’ either go unnoticed or are still considered as an ‘Act of God’. Although this issue relates to our ultimate survival, even today in India not many debates are taking place on the subject, mostly in the Television Channels. This amazing medium continues to remain obsessed with competitive high decibel shouting and slanging matches to strengthen the viewers’ appetite, even more, mostly on trivial sensationalism.

Fortunately, global awareness of the disastrous impact of ‘Climate Change’ is increasing, slowly but surely. 

I shall give below just a few examples of indirect health impact of this change:

- Extreme weather events, such as floods, droughts, tsunamis, heat-waves and other disasters would keep increasing the mortality rate. Many experts attribute the cause of the recent deluge in Chennai to ‘Climate Change’, though there are other view points too. 

- Extreme weather conditions have also started causing frequent crop failures, especially in the developing world like India. As a result, many people go hungry and children suffer from malnourishment, mostly in rural areas, precipitating adverse health consequences.

- The impact of all these on mental health is also at times devastating and should in no way be ignored. Frequent incidences of farmers’ suicide in India due to crop failures could possibly be due to their deteriorating mental health, which needs to be studied in detail.

Direct impact:

According to ‘Big Picture’ – a free and impartial educational resource that explores the innovations and implications of cutting-edge science, rising temperatures and pollution levels may act together to directly worsen various health conditions, a few examples are as follows:

- Researches say, air temperature is more likely to affect cardiovascular function, when ozone levels are high, including the heart’s electrical activity and airflow into the lungs.

- A recent review has established that air pollution sets off nearly as many heart attacks as physical exertion, alcohol or coffee. Belgian researchers examined 36 studies conducted in various countries between January 1960 and January 2010 to examine the percentage of heart attacks attributable to the common risk factors and found that air pollution increased a person’s heart attack risk by 5 percent.

- Higher temperatures may also make the body more sensitive to toxins, such as ozone.   

- Studies show allergies are on the rise in developed countries, including the United States, which could partly be rising carbon dioxide levels and warming temperatures. 

- A number of notorious diseases, such as, malaria and cholera, thrive with the increase in temperature and rainfall. To give an example, the mosquitos that carry the malaria parasites grow rapidly in hot and humid conditions. The increasing prevalence of such weather conditions in climate change is likely to spread these diseases in a much wider population.

Is there any upside for ‘Climate Change’? 

Available information also points out towards some possible, but limited benefits for ‘Climate Change’, as follows: 

- Reduced risk of dying of the elderly persons from extreme cold in the winters of the temperate countries.

- Longer summers in those countries are likely to improve agricultural yields of the farmers.

Let me hasten to add, all these upsides, if at all, may not help the developing and poorer nations of the planet Earth, as such climatic conditions are mostly prevalent in the developed nations of the world.

Need for further research:

A report titled, “A Human Health Perspective On Climate Change”, published on April 22, 2010 by ‘Environmental Health Perspectives’ and the ‘National Institute of Environmental Health Sciences’, identified the following major research areas that need to be further explored and understood in the ‘Climate Change’ perspective:

• Asthma, Respiratory Allergies, and Airway Diseases
• Cancer
• Cardiovascular Disease and Stroke
• Foodborne Diseases and Nutrition
• Heat-Related Morbidity and Mortality
• Human Developmental Effects
• Mental Health and Stress-Related Disorders
• Neurological Diseases and Disorders
• Vectorborne and Zoonotic Diseases
• Waterborne Diseases
• Weather-Related Morbidity and Mortality

The above outcome of the study is exactly in the expected line, which was “to identify research needs for all aspects of the research-to-decision making pathway that will help us understand and mitigate the health effects of climate change, as well as ensure that we choose the healthiest and most efficient approaches to climate change adaptation.”

How can we all contribute individually?

On this subject, by a release on November 26, 2011, ‘The National Aeronautics and Space Administration (NASA)’ of the United States recommended some very easy to follow steps for all of us.

It said, each individual can help in this matter by using less energy and water. For example, one may consider turning off lights and TVs when one leaves a room. Turn off the water, when brushing teeth.

It suggests, another way to help is by learning about Earth and its climate. The more we know about how Earth’s climate works, the more we shall be able to help solve problems related to climate change and that is also the purpose of this article.

In addition, besides many others, we may consider lesser use of our private cars and more of available public transports. Smokers may consider to quit smoking. We can also help by planting trees, which absorb carbon dioxide from the atmosphere.

India’s high stake:

A December 9, 2015 article published in ‘The New York Times’, titled “For Indians, Smog and Poverty Are Higher Priorities Than Talks in Paris” reiterated as follows:

At the climate talks in Paris, “few countries have so much at stake as India. For the last month, the front pages of major newspapers have been dominated by one environmental crisis after another: City-dwellers are up in arms about hazardous levels of air pollution, which has already damaged the lungs of about half of Delhi’s schoolchildren. And last month brought torrential rains and flooding in the southern city of Chennai, evoking the erratic weather that climate experts warn about.”

India’s consistent stand in various ‘Climate Change’ talks is drawing a fine balance between rapid development of the nation, with commensurate new job creation and health safety & environment. However, the apprehension that is being expressed now by many, whether that is feasible on the ground at all, for holistic measures in the right direction, with the adequate funds flow for the same.

Thus, the key concern of the Indian negotiators was, signing of any global agreement to support a strong climate regime, without requisite funding, could seriously impede India’s economic growth and development agenda. The developing nations, such as India, therefore, expect adequate and committed funding from the developed nations for generation of clean energy to drive inclusive economic prosperity of the respective emerging economies.

Developed nations still not quite on the same page?

The developed nations, even in the final text of the deal, do not seem to be quite on the same page, with firm financial commitments. As a result, a ‘Tug of War’ of objectives, as it were, surfaced in the final negotiation process – mainly between sustained economic development and stringent global measures with fund commitment to contain possible extinction of the human race in the world.

The impact of an effective implementation of the agreement is expected to last almost in perpetuity.

Conclusion:                                                                              

Finally, on the last Saturday, December 12, 2015 a new global deal to address the pressing issue of ‘Climate Change’, was agreed in Paris. Unquestionably, this is a critical step forward for all countries to save the planet Earth.

Intriguingly, the deal still does not provide for a binding commitment towards adequate funding by the developed countries, which is so essential for the developing nations to adopt clean and renewable energy to contain the devastating impact of the ‘Climate Change’.

Although, the agreement does talk about funding of US$ 100 billion a year from 2020 to 2025, this is not the legally binding part of the deal, as many people had expected.

In my view, if there is just one statesman who could be singled out for taking exemplary initiative to make the deal come through, it would be President Barack Obama of the United States. He spoke several times to the heads of the several developing nations, including India, China and Brazil, many times to iron out the differences till the last moment, for this key global issue – indeed a statesman par excellence, at least to me.

Be that as it may, the deal has now been inked, Indian Government also has expressed its satisfaction and happiness with the final text of the agreement. Still, a key question haunts: Would it produce the desired results, as expected? Well, that depends on how effectively and time bound manner the global commitments get translated into reality, with required fund flowing smoothly, to contain environmental disasters, leading to natural calamities and jeopardizing human health-safety.

Let’s all keep our finger crossed, as the saying goes, “The proof of the pudding is in the eating.”
