According to the Earth Systems Research Laboratory at Mona Loa the monthly average measured atmospheric carbon dioxide globally averaged over marine surface sites in December 2013 was 397.21 parts per million.

The climate has always changed but…

One of the major arguments of those that believe (or wish to believe) that global warming is not happening is that the climate has always changed, so what is happening today is no different from what has always happened.

As an argument it bears about as much substance and scientific relevance as the argument that global warming has stopped because in England we recently experienced unusually low temperatures of a couple of degrees below freezing. Continue reading

Hard on the news that the planet is losing ice in the Arctic and losing sea ice in the Antarctic comes news that Switzerland is losing ice from its glaciers. One study has revealed that glaciers seem to be losing about a meter of thickness every year and that the rate of losing is increasing. Continue reading

The unknowns of climate change

People who do not believe that climate change caused by human activity is happening (and they are perfectly entitled to their views) point out that there are many unknown factors in the science and theory of climate change. This is bound to be true of any scientific theory that you cannot verify by experimentation. Instead you have to make deductions from facts and circumstances. While you rely on consensus of a majority of scientists any theory is but a theory and lacks the hard proof.

Some theories are proved subsequently; when Copernicus postulated that the heavenly spheres revolved around the sun and not the earth in 1514 it was simply a theory. Within a hundred years the Church opposed Copernicus’s theory and a few years later tried Galileo for heresy for following Copernicus’ ideas. 250 years later Copernicus’ ideas were widely accepted.
