Man has always been an enemy of himself, especially in the pursuit of power and his survival. Without a sense of unity and brotherhood to intermingle socially, man has caused destruction in seclusion. The furies of nature cost his aloofness, which forced him to respect the spirit of solidarity and brotherhood among his fellow beings. With concerted or synergic efforts, man had been able to subdue the tyranny of nature. In the 19th century, geopolitical pursuit once again divided humanity. The insatiable thirst of geographical hegemonic led the world to witness the division between Axis and Allied powers, which brought about catastrophe against humanity. After that, the nuclear weapon was developed, which soon became a symbol of power after Japan marked the doomsday of human cataclysm which ended the WWII. The mighty powers readily indulged in obtaining nuclear weapons to gravitate support of states for unity— after the emergence of natural consequences of the nation-state concept. Likewise, the pursuit of natural resources gave birth to globalization which spearheaded interfaith harmony among the civilizations for complete mutual economic reliance for solidarity.
The world, however, today is again going to witness the schism on the very outstanding global issue of global warming. This is not about the problem of nature, but the consequences of overcoming it by man. Nobody is seemingly poised to dampen the ramification of global warming, which is endangering most of the states in the world.
Global warming is rising at a rapid pace. Earth has witnessed a strange rise of temperature in the preceding years. Intergovernmental Panel on Climate Change (IPCC) released the first public summary of a six-year study called Climate Change 2013— average surface temperature has risen up to the level of 2.5 degrees Celsius in numerous places around the world; global sea level has risen up to the level of 20cm; arctic summer sea ice has shrunk by four million square kilometers; and so on.
According to William Hague: “We have to face the reality of climate change. It is arguably the biggest threat we are facing today.”
The world has presently been grappling with the question on climate change — whether or not the threat from global warming, caused by burning fossil fuels, is a myth or reality. The relentless debate between contrarian and defendants of global warming has been taking place for long. Scores of papers in academic journals have been published to motivate the popular global players for undertaking viable steps for curtailing this sudden temperature rise. But the unbridled pursuit of socio-economic race has turned them blind to global warming. No state seems ready to compromise on curtailment on the production of goods processed by burning of fossil fuels, since the utility of fossil fuels at a huge amount is amounting to Green House gasses in the atmosphere, causing a trap of rebounded heatwaves coming from earth.
The very cause of global warming is exorbitant release of Green House gasses. These gases include carbon dioxide (65%), methane (16%), nitrogen (11%), water vapors, nitrous oxide (6%), ozone (2%), etc., in the atmosphere. While the main culprits of augmenting Green House gasses globally are energy production (35%), transportation (14%), and industry (21%) worldwide.
The present indicators of global warming include rising sea-level, swelling temperature, increasing permafrost and glacier melt, declining mountain snow cover, reduced fresh water level, tropical marine and homo species movements, ocean heating, burgeoning epidemics so on and so forth.
In Earth’s history, before the Industrial Revolution in the 1850, the climate changed due to natural causes in lieu of manmade activities. Most often, historically, global climate had changed because of variation in sunlight, volcanic eruptions, and tiny wobbles in the earth orbit after exposure to scorching sunrays. But numerous studies indicate that increasing atmospheric concentrations of carbon dioxide and other greenhouse gases generated by manmade activities since the beginning of the Industrial Age, have accelerated global warming.
The world is, likewise, warming because humans are emitting heat-trapping greenhouse gases. All of those statements are settled science. But the implications, changes, action, response to global warming is still under prolonged consideration.
Answering these questions requires knowledge as to how will it change as the Earth warms. One weather phenomenon that directly affects humans is the pattern, amount, and intensity of rainfall, floods, famine, drought and the availability of water. Most notably, water is, above all, essential wherever humans live, for agriculture, drinking, industry, etc. Too little water and drought increases risk of wild fires that can devour societies. Meanwhile, too much water and flooding if occurs, washing away infrastructure and lives.
The US government is in the process of decimating the climate science infrastructure. The G7 countries gaze at the US for its immediate actions. But the current US Congress, and the president, have lost the battle of science – they have no reputable scientists to hide behind in their climate change denial. However, what they are doing instead is undermining the ability to predict and plan for the future consequences of global warming. The proposed increase in the US Department of Defense budget would enable the military to buy more expensive weapons, for an amount which would have been enough to gather partial Green Climate Fund for states that are highly vulnerable to its consequences. Evidently this displays that Trump is on the move to dismantle Obama’s policies by every nook and cranny.
Trump recently decided to exit the Paris Climate Deal under the auspices of United Nation Framework Convention on Climate Change (UNFCCC), for economic reasons. Germany has criticized the move, considering that the agreement was represented by 196 parties at the 21st Conference of the Parties of the UNFCCC in Paris. As of June 2017, 195 UNFCCC members have signed the agreement, 148 of which have ratified it to mitigate global warming.
The announcement of withdrawal of the US from the Paris Climate Change agreement came up with a volley of criticism, especially condemned by the environmental campaigners and his political opponents. Environmental campaigners are of the view that American backtracking will discourage the participation of other remaining 190 states in general but China in particular. After all, the US is contributing 15%, China 30% and India 7% to global emission of CO2.
Under such a scenario, the spirit of the international treaty, Kyoto Protocol, must be rejuvenated at the earliest. Climate change is the real existing global issue after terrorism, to which there is a need to devise strategies to pacify its repercussions. There are many under developing states on the brink of catastrophe. Among them, Pakistan remains at the forefront. Alternative (non-traditional) ways for energy production must be utilized. For this, photovoltaic cell, wind power, bio-fuel, sea waves must be embraced for producing energy in an efficiently alternative way.
Most notably, unemployment anywhere will not be the cause of seeking alternative ways for generating energy, but technological advancements. Let us hope that the G7 countries would not wait for nod of the US; instead they should act unanimously for subsiding the impacts of global warming.
