During the last Ice Age, steep rises in temperature occurred in the North Atlantic area at least 20 times, with increases of up to 15 degrees Celsius. But each time the cold temperatures returned. The explanation for the increases in temperature seems to be that as the air and ocean surface became colder and colder, the deep ocean became warmer and warmer.

Major climate changes are occurring in the Arctic. The air temperature is increasing two to four times faster than the global average, and this is why the Arctic is where we can expect the first and greatest changes in the ecosystem. The question is whether this will occur gradually or if we will see an abrupt regime shift. (03/01/12)

Following the dampening effect of the 2008-2009 Global Financial Crisis, global carbon emissions from fossil fuel combustion have reached a record high of 9.1GtC1 in 2010. When including emissions from land-use change, the total emissions reached
10.0GtC. (05/12/11)

More snow accumulating on Arctic sea ice could result in slower ice growth, especially if the snow falls early in the season on thin ice. It could also accelerate melting if more melt ponds form on the ice surface in summer. On the other hand, snow reflects sunlight and can be transformed into ice, and these processes could result in growing amounts of sea ice.

A fully rational species might react with alarm and redoubled efforts to negotiate a climate change-mitigation treaty as a response to disappearing sea ice in the Arctic Ocean. When we avoid to respond this way it is because we are unsustainable by nature. Evolution - both genetic and cultural has made us this way. (18/10/11)

Less ice in the Arctic will open up for increased activity, but most likely there won’t be any large increase in the extraction of Arctic oil and gas towards 2050, according to a new study.

An increasing share of global emissions is from the production of internationally traded goods and services, according to a new study published today in the Proceedings of the National Academy of Sciences. Due to current reporting practices, this has allowed some countries to increase their carbon footprints while reporting stabilized emissions. (25/04/11)
