Guardian climate change - Fri, 22/08/2014 - 13:28
Satellite footage shows seasonal ice melt in the Arctic Ocean melting in the summer. The frozen ice caps melt throughout summer in the Northern Hemisphere until they begin to re-freeze as temperatures get colder in mid-September. Nasa says the sea ice extent in the Arctic is below average for the last 30 years. The average ice cover has decreased by 18% since 2010 to 2.31 million square miles Continue reading...

Global warming slowdown answer lies in depths of Atlantic, study finds

Guardian climate change - Thu, 21/08/2014 - 21:35

Excess heat being stored hundreds of metres down in Atlantic and Southern oceans not Pacific as previously thought

The key to behind the slowdown in global warming in recent years could lie in the depths of the Atlantic and Southern oceans where excess heat is being stored not the Pacific Ocean as has previously been suggested, according to new research.

But the finding suggests that a naturally occurring ocean cycle burying the heat will flip in around 15 years time, causing global temperature rises to accelerate again.

Scientist in focus meteorologist and climate communicator Paul Huttner | John Abraham

Minnesota Public Radio meteorologist Paul Huttner brings tremendous climate communications skills to the radio

Meteorologists have the tools to clearly understand how humans are affecting the Earths climate. For folks who study weather every day, the changes theyve seen defy natural explanation. But most meteorologists have to balance their very limited airtime and their reporting obligations with a desire to convey the reality of climate change.

Its very rare that a meteorologist, let alone a major media organization, take time to bring in-depth discussions to their listeners. But, just this has happened approximately a year ago at Minnesota Public Radio, the largest public radio enterprise in the United States with their star meteorologist Paul Huttner and his deeply knowledgeable host Kerri Miller. This unique venture (a weekly climate show CLIMATE CAST and a weather and climate blog UPDRAFT) and talented team is setting the standard for climate reporting in the United States.

Aside from scientific knowledge, Paul is blessed with the gift of communicating valuable information through stories and analogues. He is highly regarded for his ability to talk about the contentious issue of climate change by framing it in historical and consequential contexts thereby encouraging people to see the impacts on both our natural resources and societal infrastructure.

Paul Huttners innovative Climate Cast program sets a high bar for public radio stations across the U.S. He has an uncanny ability to make the timely timeless, by fitting todays breaking weather developments into the longer-range climate, and climate change, context. That he does so consistent with the worlds most authoritative scientific findings and evidence -- and yet easily digestible by an engaged but non-expert audience -- makes it all the more valuable to his audience. If only public radio audiences in other states had comparable access to such authoritative reporting and analysis on a regular basis

Paul is unique in the U.S. as an authoritative and curious radio broadcaster in a weather-obsessed state. He sounds like his audience, with the classic aww-shucks Midwestern mentality and accent. He is the only radio broadcast meteorologist to be regularly featuring climate science content, and he finds ways to engage with his audience rather than fall into the myriad political traps that haunt this beat. Thats not easy to pull off consistently, but he does. In short, MPR is lucky to have him.

Show me the money: Curtis Ravenel on meshing sustainability with revenue at Bloomberg

Guardian climate change - Thu, 21/08/2014 - 12:45

Commercial drive the oxygen of business helps sustainability flow toward quantitative, consumable and actionable new products and services, writes Christoph Lueneburger

  • This is the fourth of four posts on key sustainability traits in the executive boardroom. The first, on risk-taking, is here. The second, on resilience, is here. The third, on reaching out, is here

Curtis Ravenel dates his enthusiasm for purpose-driven business to his first job as a program associate with the National Recycling Coalition. I got very interested in the idea that being an environmentalist need not hurt your economic opportunities, he recalls.

But it would be some time before the notion defined Ravenels career.

Food and drinks companies respond to consumer pressure on climate change

Guardian climate change - Thu, 21/08/2014 - 07:30

Kelloggs and General Mills will join Mars, Unilever and Nestlé in signing BICEPs Climate Declaration, proving consumers can influence global supply chains

Campaigns dont need to be an all-dancing, all-singing affair to be a success. Over the last 18 months, over 640,000 people have spoken up as part of Oxfams Behind the Brands campaign, asking the 10 biggest food and drink companies to do more to tackle gender inequality, land grabbing and climate change. Many of the brands have listened, proving that consumer power is still a force to reckon with.

At the heart of the campaign is a desire to see Associated British Foods, Coca-Cola, Danone, General Mills, Kelloggs, Mars, Mondelez International, Nestlé, PepsiCo and Unilever, use their power to tackle global sustainability problems. This includes shaping how their suppliers do business and how the industry lobbies governments.
