What happened to the amount of carbon dioxide as years go by?
The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago.
What contributes to co2 emissions?
There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
What is being done against climate change?
For example, improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet.
What was the result of the UN climate change Conference?
The outcome of the summit was an agreement adopted by the states’ parties that called for the US$100 billion per annum “Green Climate Fund”, and a “Climate Technology Centre” and network.
When was the last time there was this much CO2 in the atmosphere?
around four million years ago
The last time global carbon dioxide levels were consistently at or above 400 parts per million (ppm) was around four million years ago during a geological period known as the Pliocene Era (between 5.3 million and 2.6 million years ago). The world was about 3℃ warmer and sea levels were higher than today.
