“In March 2015, the world hit a dangerous milestone when the average concentration of CO2 in the air surpassed 400 parts per million (ppm), according to NOAA. (Earlier, in 2013, Hawaii’s Mauna Loa atmospheric observatory detected CO2 over 400 ppm — now it’s global.) This is 40 per cent higher than CO2 levels before the Industrial Revolution started in the mid-18th Century and higher than at any time in human history.
Since the 1880s, the world’s oceans have become 30 per cent more acidic and have risen by about 20 centimetres. Sea levels continue to rise.
The last time CO2 levels were this high was around three million years ago, during the Pliocene. The world then was very different: average global temperatures were at least 3°C higher than temperatures just before the Industrial Revolution; Arctic temperatures were higher by as much as 16°C; sea levels were more than 25 metres higher. Today, a rapid return to Pliocene conditions would be catastrophic.”
This is a direct quote from the climate Council, and this information is gleened from 97% of the world’s scientists. For once they are largely in aggreement that we need to act and act now.
I for one will do all I can as a writer and filmmaker to make sure we leave this planet’s atmosphere in a better shape for our children and grandchildren than how we inherited it.
I live in Tasmania and Tasmania’s Cape Grim atmospheric observatory monitors notably’ the cleanest air in the world and it is showing higher concentrations of atmospheric CO2 and a recent spike, likely from the massive fires burning in South America, some 5000km across the Southern Ocean. These fires are unprecedented and are attributed directly to climate change, so argue all you wish but the majority of the world’s governments are acting, because climate change will not go away just because Trump thinks its a hoax.
