CO2 and Other Gases

To summarize, in only 200 years, the humans have forced climate to change more rapidly than in 800,000 previous years… by burning large amount of fossil fuels that trap the radiations from the Sun in the Atmosphere.

What are these gases?

Mostly, we refer to Carbone dioxide (known as CO2), which is the main gas emitted by human activity, but this is not the only one. There are contributions from many other gases including ozone, methane, nitrous oxide and human-made gases such as CFCs (chlorofluorocarbons). As of December 2015, the Manua Loa Observatory in the Pacific Ocean has registered a concentration of CO2 in the atmosphere of more than 400 particles per million. To give you a reference, scientific evidence tells us that concentration over thousands of years has always been below 300. When concentration will rise over 450 to 550, the changes will be irreversible and effects enormous.

How are these gases produced?

Myanmar, as other countries under the UNFCC Convention, is gathering inventories of emissions and their sources. They are published on a regular basic in the National Communications, which you can find here.

At global level, they are emitted as explained in the figure below:IPCC

In Myanmar, they are emitted according to the info-graphic below:

As you can see, according to data from the year 2000 Myanmar absorbs more CO2 than it emits, thanks to its forests. It is called carbon sink.
