Imagine a world where the rooftops and pavements of every urban area are resurfaced to increase the reflection of the Sun’s light rays. Well, this is exactly what a group of Canadian researchers have simulated in an attempt to measure the potential effects against global warming. Continue reading

Brightening rooftops and pavements can cool the Earth by 0.07 degrees
Sea level rise brings millions of Americans at risk of storm surge flooding
Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests.
Figure 4 - 2nd of two Environmental Research Letters SLR publications. Sea level rise storm surge flooding risk along US coast. For the ensemble average estimate of relative SLR at each gauge, projected return periods, by 2050, for floods currently qualifying as 100 yr events.
Today´s paradox: European cold winters associated with Arctic warming – and positive(!) AO
Warming in the Arctic would increase the chance of cold winters in Europe and parts of North America and Asia. There have now been three consecutive studies that reach this conclusion in as many years. That means it is about … Continue reading
What’s up with geoengineering? Most people don’t know.
Geoengineering can be compared to taking a pill for being overweight. Instead of trying to tackle the root of the problem, it tries to cure the symptoms. But like medicine for reducing obesity we will probably need it in the … Continue reading
Crop albedo geoengineering: plant albino sugar beet and have a 1 degree cooler summer
But in order to save the climate it would be advised to first chop down that dark pine forest.
Geoengineering can save Greenland, model suggests
We recently witnessed a new Greenland melting record. And according to a new paleoclimate comparison by James Hansen we could be in for meters of sea level rise within this century, due to expected non-linearity of the melting process.
Geoengineering La Niña
According to the WMO the current La Niña episode will continue to exist for at least another 2-4 months. Other sources state it may last until 2012. This La Niña could be the strongest in decades and is likely to … Continue reading
