Green house gases are those gases that contribute to the greenhouse effect by absorbing infrared radiation. Carbon dioxide and chlorofluorocarbons are examples of greenhouse gases.
Climate Change conferences are held to work around a mechanism to preserve and protect our planet earth. And Paris Climate agreement aims for under 2 deg warming, but as mostly happens with big conferences, we may not be able to achieve this.
In 2010, the world emitted greenhouse gases equivalent to about 48 billion tons of CO2. With no climate policy, the researcher’s project annual emissions would rise to about 65 billion tons in 2030.
Technically, the 195 countries on the pact are agreeing to keep global average temperatures less than 2°C above pre-industrial times. A late addition to the agreement purports to aim to stay below 1.5°C above. Unfortunately, it now seems that the actual emissions pledges submitted by each nation (which go through 2030) don’t get us there. The fact remains that the 2°C goal is becoming more improbable every year.
