Climate, Ice, and Weather Whiplash

Peter Sinclair: Last year I spoke to Dr. Jeff Masters and Dr. Jennifer Francis about the emerging research linking “weather whiplash” events, back to back extremes of all  types that seem to have become our new normal, and the disappearance of arctic ice. This year, the extremes continue. I’ve revisited Dr. Francis on the issue, to talk about what…

“Climate Change Is Real” – Former NY Army Corps Commander John Boulé

5/16/13: At the WNET Sandy town hall, the former commander of the New York District, Army Corps of Engineers, John Boulé warns New Yorkers to stop ignoring climate change and start preparing for higher sea level rise and more frequent and more powerful storms.   Brad Johnson: At a May 16 televised forum on the recovery from Superstorm…

Humid air and the Jet Stream help to fuel more intense thunderstorms/tornadoes

“The fuel for the more intense storms would be the predicted warming of the Earth caused by the burning of fossil fuels that release greenhouse gases.” A combination of a slower Jet Stream (see video for explanation and study) and a more humid atmosphere increase the likelihood for a more intense thunderstorm environment. This conclusion…

Tar-Sands Oil Makes Climate Change Unsolvable

By Alex Morales / Bloomberg: Exploiting oil and gas trapped in tar sands and shale threatens to make climate change“unsolvable,” said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s. Conventional reserves of oil, gas and coal already have more carbon embedded in them than is safe to burn without causing “dangerous” levels of…

Jennifer Francis: Wacky Weather and disappearing Arctic Sea Ice are they connected?

Dr. Jennifer Francis – Rutgers University “Extreme weather events are increasing in frequency and intensity all around the northern hemisphere.” Concurrently, Arctic sea ice is in an accelerating decline, the entire surface of Greenland melted for the first time in at least 150 years, glaciers are disappearing around the world, and snow cover on Arctic…

Kevin Trenberth: How To Relate Climate Extremes to Climate Change

Public lecture by Distinguished Senior Scientist at the Climate Analysis Section at the National Centre for Atmospheric Research (NCAR), Kevin Trenberth held at UNSW on October 16, 2012. “Heavy precipitation days are increasing even in places where precipitation is decreasing.” Framing the way to relate climate extremes to climate change Abstract The atmospheric and ocean environment…

Fires, Floods, and Heavy Snow: an Extreme May Weather Situation

Dr. Jeff Masters / via Wunderground – A highly unusual jet stream pattern is bringing a bizarre combination of heavy May snows, flooding, extreme fire danger, and well below average severe thunderstorm activity to the U.S. A strong “blocking” high pressure system has set up over Greenland, blocking the normal west-to-east progression of weather systems. A truly unusual situation has developed where the blocking high has forced a low pressure system near Greenland to move southwestwards to a point just off the New England coast. The blocking high has also forced an unusually sharp southwards dip in the jet stream over the Central U.S., where all-time May snowfall and cold temperature records are being set.

NASA: Warming-Driven Changes in Global Rainfall


By Kathryn Hansen NASA Goddard Space Flight Center. A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.

Model simulations spanning 140 years show that warming from carbon dioxide will change the frequency that regions around the planet receive no rain (brown), moderate rain (tan), and very heavy rain (blue). The occurrence of no rain and heavy rain will increase, while moderate rainfall will decrease.

Does Arctic Amplification Fuel Extreme Weather in Mid-Latitudes?

Jennifer Francis, Rutgers University, 25 January 2012. The “Arctic Paradox” was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for…
