As carbon emissions concentrate in the atmosphere, the planet is burning up... and fast.
That is the well-known bottom line when it comes to human-caused global warming and climate change.
Over the course of April, according to the world's premiere atmospheric monitoring station Mauna Loa, Hawaii, which is run by the National Oceanic and Atmospheric Administration (NOAA), the concentration of carbon averaged more than 400 parts per million for the entire month for the first time in human history.
Last year, the Intergovernmental Panel on Climate Change started the publication of its 5th Assessment Report (or AR5), initially showing the work by the Working Group I, which deals with the physical basis of climate change. Now, the AR5 process continued with the publication of the “Summary for Policy Makers” by the Working Group II, concerning “impacts, adaptation and vulnerability.”
When you are racing through a rural landscape on a bullet train, it looks as if everything you are passing is standing still: people, tractors, cars on country roads. They aren’t, of course. They are moving, but at a speed so slow compared with the train that they appear static. So it is with climate change.
There are choices that need to be made if dangerous climate change is to be avoided in the 21st century. Previous reports from the Intergovernmental Panel on Climate Change (IPCC) have confirmed that the influence of human activities on the climate is unambiguous, and that climate change will have a major impact on human activities and ecosystems.
Greenhouse gas emissions grew almost twice as fast in the past decade as they did in the previous 30 years, bringing the world another step closer to a level of warming that could wreck havoc with the climate if humans don’t end their dependence on fossil fuels, says a shocking new report by the UN climate panel.
A new study sponsored by Nasa's Goddard Space Flight Center has highlighted the prospect that global industrial civilisation could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution.
