[Edit: Hurricane behaviour is notoriously hard to predict. After reaching extreme wind speeds above the Pacific, hurricane Patricia quickly disintegrated above land. The main damage might now be in extreme rainfall, flooding and possible mudslides - no longer direct wind … Continue reading →
Ten years after Katrina* the world is on the brink of a whole new cluster of climatic disasters, including wide-spread coral bleaching, Pacific atol floods, possibly another devasting Brazil drought and another record-breaking hot year, following from the currently developing … Continue reading →
According to the world’s best-established dynamical climate models (e.g. NOAA NCEP, NASA GMAO) the 2015 El Niño is set to peak to dramatic proportions just before and possibly also during the all-important Paris climate summit – the UNFCCC’s ‘COP21′ – … Continue reading →
White sulfur aerosols cool the climate; black carbon soot warms the climate. So when you mix the two kinds of aerosol pollution up in the Asian brown cloud, one would expect climate effects to even out. Unfortunately in our physical … Continue reading →
Yesterday we took a better look at the climate records of 2010 – a year characterized by many extremes and a ‘binary’ El Niño/La Niña Southern Oscillation – that switched suddenly from the one state to the other, somewhere in … Continue reading →
Is what a group of engineering policy researchers and atmospheric scientists from Carnegie Mellon and MIT asked themselves. Considering increasing hurricane damage around the Gulf of Mexico – and technological options – they get to a ‘maybe’.
Over the past 60 years the easterly trade winds over the tropical Atlantic Ocean have decreased in strength, say Hiroki Tokinaga and Shang-Ping Xie of the University of Hawai. The pattern suggests a permanent ‘Atlantic El Niño’, changed precipitation over … Continue reading →
