How close are climate tipping points
The Intergovernmental Panel on Climate Change (IPCC) has warned that surpassing 2 degrees celsius of warming could have catastrophic consequences and that we need to keep global warming to 1.5 degrees celsius.
Climate safety valve
Scientists at the University of Southhampton have discovered that large chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide over geological time thus stabilizing temperatures at Earth’s surface.
Climate change axis shift
The Earth’s axis is not static but is always moving. The way water is distributed on Earth’s surface is one factor responsible for the shift.
Last CO2 level high
The last time CO2 levels were as high as today, in a time called the Pliocene, was some 3 million years ago when sea levels were around 30 feet higher. The Pliocene was a significantly warmer world, likely around 3 degrees warmer than pre-industrial temperatures of the late 1800’s. Much of the Arctic had melted. …
