The Paris climate accord has decided to restrict global warming by 2 deg, by the turn of the century. Earth's atmosphere can take upto 3200 Gigatonnes of CO2 to restrict to this 2 deg rise. So far since dawn of humanity and Industrial revolution, we have pumpes 2000 Gigatonnes into the earth's atmosphere.
At the present pace of development and Industrial activity on earth resulting in CO2 emissions, we would exhaust the permissible extra 1200 Gigatonnes of CO2 in 30 years, ie. by 2045 AD.
This is what the Paris climate accord discussed but could not reach any binding limits and promises by China, US and India, the three top gross global polluters, in that order.
If we are not ready for accepting binding limits, we need to either restrict our energy consumption or increasingly switch to renewable sources.
Creating an awareness is the first step.
If the example of the technologically far superior Kochi International airport in Kerala, India, the first and only international airport in the world handling annually 7 million passengers, to be energy-neutral and running 100% on solar energy, could be followed up by the other so-called developed countries of the world, considered the tipping point for global solar energy acceptance, we can tackle or even put in reverse gear global warming to a great extent.
