ABSTRACT: Wildfire activity in boreal forests is anticipated to increase dramatically, with far-reaching ecological and socioeconomic consequences. Paleorecords are indispensible for elucidating boreal fire regime dynamics under changing climate, because fire return intervals and successional cycles in these ecosystems occur over decadal to centennial timescales. We present charcoal records from 14 lakes in the Yukon […]
September 2014 (BAMS) – Seasonal and annual temperature anomalies around the globe were highly skewed toward positive (warm) extremes in 2013, as in the recent few decades. Although global warming has been described as “pausing” since 2000, global temperatures remain at anomalously high levels, and warm annual and seasonal temperature extremes continue to far outpace […]

By Rory Carroll6 October 2014 Los Angeles (theguardian.com) – “Stay safe!” went the mantra, as tens of thousands of cyclists zipped around Los Angeles this weekend for CicLAvia, an event to celebrate public spaces. Fellow riders, pedestrians and police shouted it as much in greeting as exhortation since clearly the safest thing was to be […]
By Trevor Hughes10 September 2014 DENVER (USA TODAY) – The iconic pine and aspen forests of the Rocky Mountains are dying off at an alarming rate thanks to conditions exacerbated by climate change — drought, insect infestations and wildfires — a new report says. Colorado alone could lose 45% of its aspen stands over the […]
By Joseph Serna12 September 2014 (Los Angeles Times) – The first eight months of 2014 were the warmest on average in California’s history since record-keeping began in 1895, federal scientists announced this week. The average temperature was 62.6 degrees in California over the time period, coming in at 1.1 degrees hotter than the previous high […]
By Peter Hannam, Environment Editor21 July 2014 (Sydney Morning Herald) – A common refrain by climate sceptics that surface temperatures have not warmed over the past 17 years, implying climate models predicting otherwise are unreliable, has been refuted by new research led by James Risbey, a senior CSIRO researcher. Setting aside the fact the equal […]
By Brian Brown6 July 2014 VEGA, Texas (NBC News) – While a high-pitched wind rattles the windows, and assaults a flapping, fraying American flag in the front yard, Lucas Spinhirne knows he’s staring into an abyss that many in Texas—and across the world—may be forced to contemplate. The once bounteous quantities of water that flowed […]
2 June 2014 (Australian Associated Press) – Australia has experienced its hottest two years on record and high temperatures are set to continue through winter in a clear sign of climate change, a report warns. May 2012 to April 2014 was the hottest 24-month period ever recorded in Australia, but that is likely to be […]
By Andrea Thompson20 May 2014 (Climate Central) – The torrential rains and catastrophic floods that raged through parts of Bosnia and Herzegovina, Serbia, and Croatia were unprecedented in the historical record of the region, going back 120 years. But extreme weather events like this one are something communities may have to contend with more and […]
