The Big Freeze

The Big Freeze is a term used to describe the short and sudden change of climate into an ice age brought about by abrupt climate change. The Younger Dryas period was the most recent Big Freeze that was preceded by rapid warming and deglaciation in the Northern Hemisphere. Are we witnessing similar climate change today?

“the effects of climate change will be most felt in the Northern Hemisphere ”

The possibility of a Big-Freeze in the next 100 years is real, presenting great challenges for Governments, academics, engineers and the general public. Sound, scientific evidence from established sources including the Intergovernmental Panel on Climate Change (IPCC), suggests that increasing concentrations of CO2 in the atmosphere and associated increase in temperatures (global, regional and local) will result in the dissapearance of the Arctic sea ice and collapse of the Greenland ice cap. Similar trends are being witnessed in Antarctica with the collapse of major ice sheets.

On this scale, it is almost certain that resultant meltwaters wll reduce the saline content of the North Atlantic and shut down the Gulf Stream. This will send the Northern Hemisphere back into an ice age very quickly, certainly within a lifetime if not less than 25 years.
