‘Too soon to tell …’ Staff Report *More Summit Voice stories on this subject are here FRISCO — There’s been lots of speculation and some early research on a possible link between soaring temperatures in the Arctic and extreme weather in North America and Europe, but the jury is still out, according to scientists with … Continue reading Global warming: New NOAA study eyes link between Arctic meltdown and extreme weather in mid-latitudes

Study eyes impacts to North Atlantic Oscillation Staff Report The loss of Arctic sea ice may not lead directly to an increase in cold weather extremes in Europe, according to scientists who studied the links between Arctic changes and mid-latitude weather. In the study, scientists with the University of Exeter found that dwindling sea ice … Continue reading How will the melting Arctic affect European weather?
Australian scientists document early start to melt season Staff Report Australian scientists say Antarctic sea ice started its annual spring retreat early this year and has set new daily record lows for extent during late September — during the Austral spring, when Antarctic sea ice is at a maximum. In a press release, the Antarctic … Continue reading Antarctic sea ice peaks near record-low extent
‘Blocking highs’ becoming more common over Greenland Staff Report Just a few weeks after scientists reported record early melting on parts of the Greenland Ice Sheet, a new study helps explain some of the recent dramatic climate shifts in the high latitudes of the northern hemisphere. Stationary high pressure systems over Greenland have become more … Continue reading More evidence that melting Arctic ice drives widespread changes in northern hemisphere weather patterns
Extreme rainfall events increasing globally Staff Report Destructive floods that raged through parts of the Balkan region in 2014 are part of a global trend toward more extreme rainfall events — a pattern increasingly linked with changes in atmospheric circulation. In new findings published this week, scientists found that disastrous floods in the Balkans two … Continue reading Extreme 2014 Balkan flooding linked to airstream slowdown
Melting sea ice and overall rapid warming in the Arctic are factors in the development of so-called blocking high pressure systems — air masses spinning clockwise that block cold, dry Canadian air from reaching Greenland.
This year edition features sessions on Arctic ice melt and western wildfires Staff Report There’s a global climate deal on the books, but humankind will continue to grapple with the effects of greenhouse gas emissions for decades to come, including the almost inevitable meltdown of ice sheets and glaciers that will raise sea level steadily. … Continue reading Weather and climate summit returns to Breckenridge
Sea ice decline has accelerated since 1996 Staff Report As projected a couple of weeks ago, Arctic sea ice bottomed out at the fourth-lowest extent on record, according to NASA and the National Snow and Ice Data Center. This summer’s ice extent was about 394,000 square miles above the all-time minimum set in 2012, but … Continue reading Arctic sea ice extent hits 4th-lowest minimum on record
‘The risk of high-impact heat waves is likely to increase’ Staff Report FRISCO — Summer heatwaves, already getting longer and hotter because of human-caused global warming, are set to get even worse, as the overall climate-warming trend disrupts atmospheric circulations that bring relief from long spells of hot weather. A recent study by scientists with … Continue reading Climate: Arctic sea ice meltdown weakens summer storms, leading to longer, hotter heatwaves
Arctic cloud formation still a climate wild card STAFF REPORT FRISCO — The ongoing loss of Arctic sea ice is probably already affecting weather and climate in the mid-latitudes of the northern hemisphere. Researchers aren’t exactly sure of how, but there’s been plenty of speculation, mostly focused around changes in the jet stream. Global warming: … Continue reading Global warming: New NASA aerial mission to explore impacts of Arctic sea ice loss
