Both historical and 60-year trend show Dutch winters are warming – these graphs tell you how, why – and what to expect

Falling snow flakes are humbling. Not just because of their beauty, but also because of their gentle ability to completely paralyse a developed and overpopulated country with traffic jams, clogged railroad switches and closed runways. But although that (together with … Continue reading →

Largest known sea level rise took less than 350 years

Ocean level rise is known as one of the most disquieting effects of global warming, with more than three billion people living on the coast or less than 200 kilometres land inward and one tenth of the world population living … Continue reading →

Carbon dioxide’s climate effects confirmed: temperatures followed rising CO2 levels during last deglaciation

There has been much speculation about what exactly caused the end of the last ice age 10,000 years ago. Some say the Earth’s orbital changes were the cause, others say it was an increase in atmospheric CO2. But although a … Continue reading →

Graph of the day: weather extremes are on the rise

weather extremes graphWhy write a full news story when a single graph tells you everything: ‘unprecedented records in monthly mean temperature’ between 1900-2000 for 17 weather stations across the globe.

Can medieval volcanic eruptions have caused global cooling when tree rings don’t show?

A group of researchers led by climatologist Michael E. Mann of the Earth System Science Center of Pennsylvania State University says the dendrochronological record does not always offer the best temperature reconstruction. Apparently some trees find it hard to distinguish … Continue reading →

‘No, climate sensitivity is not smaller, it is higher than we thought’ – because organic aerosol feedbacks mask warming

Says an international research group led by Gothenburg University. It serves to show individual climate sensitivity studies are never conclusive but add up bits of fresh understanding to an already enormous pile of data and knowledge.

World average land temperatures have risen by almost 1 degree since 1955 – says 4th consecutive study

Whom would you rather believe? The world’s three best-established atmospheric research institutes – or a Berkeley dream team with the current Physics Nobel Prize laureate, backed up by the largest collection of land temperature measurements ever? So sorry to confuse … Continue reading →
