Climate Analogs & Cryosphere

PNAS December 10: Models Show Abrupt Transition of Climate to Past Geologic States Main Messages: Already in 2030, Earth’s climate will approach that of the mid-Pliocene (-3 million years) if current emissions levels continue unabated, eg RCP8.5 through 2030. Pliocene (–3 million), temps 2.8°-4.6° above pre-industrial, with 20+ m. SLR If emissions continue on an […]

How the Polar Vortex Works (and Why Record Cold is Yes, Part of Global Warming)

Note:  ICCI often gets questions about the unusually cold weather that occasionally has begun to hit sub-Arctic Europe and North America.  Below in brief is an explanation and direction to other resources and articles: The so-called “polar vortex” is a regular upper-atmosphere phenomenon that normally, stays centered over the North Pole.  It comprises very high-level […]

May IceBlog: Anything But Pro Forma Note:  Statements at Arctic Council ministerial meetings are often very pro-forma.  The May 11 statement in Fairbanks by Swedish Foreign Minister Margot Wallström was anything but — instead it was a call to science-based, and economics-based, action: Excellencies, colleagues, Arctic friends, it is truly a great pleasure to be […]

ICCI’s hallmark is a deep belief in the power of solid science to convince policymakers and decision makers to change course before climate change overtakes us all.  Not all leaders, and not all at once — but enough to make a difference.  We have been spreading the increasingly-clear message from the cryosphere (snow and ice) […]

“These people know nothing!  Nothing!” This outburst from an eminent Antarctic researcher was as unexpected for me as it was emphatic.  It came just outside a seminar during one of the climate negotiating sessions before Copenhagen, where I thought the negotiators present (many former colleagues, known from my own years in diplomacy) had asked intelligent […]

Fire in the Fields – “Burning” the Cryosphere “Open burning” refers to a common agricultural practice found today throughout the world: the regular and periodic burning of lands, supposedly cheaply and quickly to remove excess vegetation.  This may be crop residue such as straw, weeds, lands to be cleared, or in forestry understory prior to […]

What Happens in the Arctic…. As world leaders, including President Obama, Secretary of State John Kerry and a number of foreign ministers, head to Alaska this weekend to discuss the threat of climate change in the Arctic (and ICCI will be there, with our European Director Dr. Svante Bodin addressing the ministers on black carbon), […]

Explaining Climate:  What Rockström Said! Sometimes in the struggle to convey the seriousness and, above all, the immediacy of the threat of climate change, one runs across a speaker or writer that simply causes the reaction, “what he said!” This was definitely the case for me on July 12 in Sweden when Johan Rockström,  former […]

The “Road to Paris” Goes through Cryosphere With the Bonn UNFCCC climate negotiations taking place next month, the phrase “road to Paris” is the theme of countless policy forums and media coverage.  For ICCI, that “road” focuses on cryosphere – but increasingly, science is telling us that any path towards a new climate agreement in […]

Summer Forecast: Hot, with Frequent Fires Sometimes ICCI gets the question of how open field and forest burning, seeming quite far from the Arctic or other regions, can have such an impact at higher latitudes (or in the Himalayas, Andes or other mountain regions, on mountain glaciers and snowpack).  One explanation, of course, is the […]
