In the era of smart phones and artificial intelligence (AI), when people seem to be too busy with their efforts to make life easier, the most neglected part of life is the environment. In the game of profit and loss, the corporate world is shortsighted by their short time lucre. The climate change is real, even a farmer can understand that. Our theory of six seasons no longer holds to be true. But yet, some people don’t want to consider it.
It is certain that the Earth’s climate has desperately changed through past many years. What is the present statistics? Is it at a level where we really should be concerned? How much responsibility should mankind take in this? Let’s take a look.
NASA says, “The Earth’s climate has changed throughout history. Just in the last 650,000 years, there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” 
The human activities that are responsible for climate change mostly come from the energy production and transportation. The primary source of which is fossil fuel. Our addiction to carbon not only affects our climate but is also pushing us towards an uncertain grievous future. The Guardian shared an interactive clock to remind us about our carbon usage. It estimates how much greenhouse gas the world is emitting right now – and how much we have left to emit if we want to avoid catastrophic climate change. 
Paris Agreement, the savior 
When everything seemed very despairing, at the 21st Conference of the Parties of the UNFCCC in Paris on 12 December 2015, an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation, adaptation and finance starting in the year 2020, was negotiated by representatives of 195 countries.
The aim of this agreement was to hold the increase in the global average temperature to below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels.
What is so important about this 2 °C?
The 2 degree is quite arbitrary as a choice. It was aimed to make a starting point. However, it is too low to make an impact in the present situation.
Scientists warned that beyond 2 degrees, it dramatically raise the chances of higher sea levels, alter the weather patterns, and an overall more inhabitable earth.
In a report, NASA has recorded that the global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century.

When it appears to be too promising, the frustrating part of this agreement is its nature, as it is completely voluntary. Whether any of the signed countries will fulfill the 2-degree target, it completely depends on the concerned government. While 195 countries have agreed to the accord, there is no accountability for fulfillment.
The responsibility of the first world countries
When it comes to energy production, greener implies costlier. The developing countries are not in a state for the immediate imposition of these restrictions. A research says the worst impact of climate change will be in the developing countries first. From the perspective of fundamental equality, they need time and help to develop themselves from the richer ones. The Paris Agreement countries like the US, are supposed to help the developing countries by sending $100 billion a year. Although the help is not mandatory much like the agreement itself.
Recent developments and America’s exit from Paris Agreement 
Recently, the US President Donald Trump declared that U.S. is withdrawing from the landmark Paris climate agreement, striking a major blow to the worldwide efforts to combat climate change. His standpoint on climate change is that it is slowing down the US economy and causing more damage than the climate itself.
The fight against global warming is already very tough and will be tougher in coming days. Various environmental groups and activists already expressed their concerns. Several corporate organizations like Apple, Facebook, Google etc. conveyed their displeasure by putting a full page advertisement in New York Times.
Here are some tweets and post about the same:
Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world.— Elon Musk (@elonmusk) June 1, 2017
Disappointed with today’s decision. Google will keep working hard for a cleaner, more prosperous future for all.— Sundar Pichai (@sundarpichai) June 1, 2017
Decision to withdraw from the #ParisAgreeement was wrong for our planet. Apple is committed to fight climate change and we will never waver.— Tim Cook (@tim_cook) June 2, 2017
We believe climate change is an urgent issue that demands global action. We remain committed to doing our part. https://t.co/Gfu7P2ESlL— Satya Nadella (@satyanadella) June 1, 2017
Hope our concern will be addressed someday.
