Breaking Science Flash: Mexico’s Cyclone Patricia could become STRONGEST HURRICANE ever measured – ‘Category 6′

[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

To shear or not to shear – these 5 images show El Niño’s possible effect on Atlantic hurricanes, and other jet stream stuff

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

2015 El Niño produces new climate record: 3 simultaneous Pacific category 4 hurricanes

Small Island States don’t (yet*) make global headlines, but this NASA picture shows a new Pacific climate record, which has a story for us all.

NASA climate model forecast shows 2015 El Niño to go off the charts during Paris climate summit

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

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.

Indian aerosol pollution stimulates tropical cyclones over Arabian Sea – because of monsoon disturbance

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

Does cyclone modification geoengineering make sense?

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’.

Climate trend: weaker Atlantic trade winds?

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
