Arctic solar geoengineering options modeled – feasibility investigated, including seasonal approach

solar geoengineering ArcticScientists are slowly starting to get practical on geoengineering. Cooling the entire planet with stratospheric solar geoengineering could cost only 5 billion dollars per year. And opting for artificial clouds saving the Arctic with geoengineering could be as cheap as 24 million euros.

Now a group including renowned climatologists and leading geoengineering thinkers Ken Caldeira and David Keith tries to investigate ways to alleviate some of the (likely) unwanted side effects of Arctic solar geoengineering.

Climate change may provoke new ozone holes over populated areas in two different ways – increasing risk of skin cancers

In a couple of weeks’ time humanity can celebrate the 25-year anniversary of the Montreal Protocol, our greatest environmental success story. In the margins of this good news there are however also a few new ozone concerns. Climate change may … Continue reading →

During MIS11 interglacial sea levels were 6-13 m higher, Nature study shows

If you are interested in sea level rise news, you have a busy week. First we learn from a Nature Climate Change publication that the Greenland ice sheet is already gone. Then earlier today two studies published in Environmental Research … Continue reading →

Red meat consumption shortens lifespan, Harvard study concludes

A new study from Harvard School of Public Health (HSPH) researchers has found that red meat consumption is associated with an increased risk of total, cardiovascular, and cancer mortality. The results also showed that substituting other healthy protein sources, such as fish, poultry, nuts, and legumes, was associated with a lower risk of mortality.

Mid-Atlantic suburbs can expect an early spring thanks to the heat of the big city

Urban heat island effect

Urban heat island around Washington and Baltimore would lead to longer growing season, warmer autumn and spring

If you’ve been thinking our world is more green than frozen these days, you’re right. A recent study has found that spring is indeed arriving earlier – and autumn later – in the suburbs of Baltimore and Washington, D.C. The reason? The urban landscape traps heat in the summer and holds it throughout the winter, triggering leaves to turn green earlier in the spring and to stay green later into autumn. The result is a new, extended growing season.

SRM geoengineering more likely to increase global food production

If we would pump aerosols in the stratosphere to artificially cool the Earth and thereby compensate (part of) the current climate warming, we would be permanently living under a slight sunshade. That would mean in a futuristic world it may … Continue reading →

He who controls ENSO rules all: even flu pandemics now connected to La Niña – 2012 virus forecast

If this is true best stack up on your supply of antiviral drugs, because there would be an above-average chance of experiencing another influenza pandemic during the approaching northern hemisphere spring or summer of 2012 (as indeed La Niña is … Continue reading →
