Graph of the Day: Harp seal strandings and sea ice decline, 1991-2010

ABSTRACT: The effects of climate change on high latitude regions are becoming increasingly evident, particularly in the rapid decline of sea ice cover in the Arctic. Many high latitude species dependent on sea ice are being forced to adapt to changing habitats. Harp seals (Pagophilus groenlandicus) are an indicator species for changing high-latitude ecosystems. This […]

Graph of the Day: CO2 and acidity measurements at Monterey Bay, 1993-2010

8 August 2013 (CalEPA) – Carbon dioxide (CO2) is considered to be the largest and most important anthropogenic driver of climate change (see Atmospheric Greenhouse Gases indicator, page 19). CO2 is continuously exchanged between land, the atmosphere, and the ocean through physical, chemical, and biological processes (IPCC, 2007c). The ocean absorbs nearly one quarter of […]

Virginia mayors: Time to respond to climate change – ‘There are more 100-year storms in the last 15 years than we’ve ever seen’

By Bill Kovarik16 September 2013 WILLIAMSBURG, Virginia (The Daily Climate) – Weary of debating the causes of climate change, mayors and other elected officials from Virginia’s battered coastal regions gathered here last week and agreed that local impacts have become serious enough to present a case for state action. “We are here to ask for […]

Ear wax from whales records ocean contaminants – ‘It’s been 30-plus years since we’ve stopped using DDT, but to still see it showing up at such high concentrations is surprising’

By Rhitu Chatterjee16 September 2013 (NPR) – How often do whales clean their ears? Well, never. And so, year after year, their ear wax builds up, layer upon layer. According to a study published Monday, these columns of ear wax contain a record of chemical pollution in the oceans. The study, published in Proceedings of […]

Colorado’s ‘Biblical’ flood in line with climate trends – Over 1200 people missing – ‘This is clearly going to be a historic event. The true magnitude is really just becoming obvious now.’

By Andrew Freedman13 September 2013 (Climate Central) – The Boulder, Colo. area is reeling after being inundated by record rainfall, with more than half a year’s worth of rain falling over the past three days. During those three days, 24-hour rainfall totals of between 8 and 10 inches across much of the Boulder area were […]

Graph of the Day: Decrease in High Plains Aquifer water levels, predevelopment to 2011

19 May 2013 (The New York Times) – Portions of the High Plains Aquifer are rapidly being depleted by farmers who are pumping too much water to irrigate their crops, particularly in the southern half in Kansas, Oklahoma and Texas. Levels have declined up to 242 feet in some areas, from predevelopment — before substantial […]
