Excerpts;

Renewable energy could meet nearly 80 percent of the world’s energy needs by mid-century and play a crucial role in fighting global warming, the UN’s climate scientists said Monday in a major report.

The 194-nation Intergovernmental Panel for Climate Change (IPCC) said that renewable sources had grown rapidly, were widely competitive with fossil energies and, technically, had almost limitless potential…

A Spanish Island’s Quest to Be the Greenest Place on Earth

Excerpts;

At the moment, the project that will transform the future of El Hierro doesn’t look like much more than a hole in the ground. Or two, to be exact: one on top of a mountain, another smaller one down below, and in between, a long stretch of pipeline tinted the same color as the scrub that grows so abundantly on this volcanic island.

Nauru use UN spotlight to confront developed world over climate change

naura-pacific
Nauru, Micronesia, South Pacific.
Nauru, world’s smallest independent nation, is among the islands most threatened by rising sea levels. It is is a small Pacific island about the size of Manhattan with a population of approximately seven thousand people. The economy of Nauru has been almost wholly dependent on phosphate, which has led to environmental catastrophe on the island, with 80% of the nation’s surface having been strip-mined.

Excerpts;

Last month I returned to Nauru, the smallest member of the United Nations and my home.

The sea around us is getting warmer, droughts have become commonplace, and the coastal erosion is as bad as anyone can remember.

Similar trends are occurring across the Pacific and they have grave implications for the fish stocks we depend on for food, our freshwater supplies, and the very land we live on. Scientists have warned us that the situation will get much worse unless the greenhouse gas pollution responsible for global warming is dramatically reduced…

Nauru, une île à la dérive, Un Documentaire Video (30 minutes), Thalassa
” Ce reportage est pour moi symbolique des dérives des sociétés de consommation, de leur impact tragique sur les peuples fragiles et isolés. Autrefois deuxième pays le plus riche au monde, après l’Arabie Saoudite, Nauru est aujourd’hui un des pays les plus pauvres du Pacifique. Ce sont les mines de phosphate, qui recouvrent la totalité de l’île, qui ont fait autrefois la grande richesse des Nauruans. En une trentaine d’années à peine, l’exploitation du phosphate a transformé la petite démocratie en un pays corrompu et clientéliste ; elle a causé la faillite de l’Etat et la ruine de ses habitants, elle a enfin détruit toute une culture traditionnelle.”

Endangered places around the world

Excerpts;

We all know that climate change melts glaciers and shifts sea levels. But have you ever thought about how rising temperatures can threaten beautiful places in every corner of the world? Some of these spots may be closer to home than you think.

In celebration of Earth Day, Yahoo! News interviewed Gaute Hogh, publisher of the book 100 Places to Go Before They Disappear (distributed by Abrams in the U.S.). Hogh was inspired to produce the book after witnessing the effects of global warming in his native Denmark. He wanted to show how natural beauty around the globe could be forever altered by climate change…

Arctic’s Icy Coastlines Retreat as Planet Warms

Excerpts;

The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a metre per year on average. This means substantial changes for Arctic ecosystems near the coast and the population living there.

A consortium of more than thirty scientists from ten countries, including researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association and from the Helmholtz Centre in Geesthacht, comes to this conclusion in two studies published in Estuaries and Coasts…

Ozone Layer Faces Record 40 Percent Loss Over Arctic

Left: Ozone in Earth’s stratosphere at an altitude of approximately 12 miles (20 kilometers) in mid-March 2011, near the peak of the 2011 Arctic ozone loss. Red colors represent high levels of ozone, while purple and grey colors (over the north polar region) represent very small ozone amounts. Right: chlorine monoxide – the primary agent of chemical ozone destruction in the cold polar lower stratosphere – for the same day and altitude. Light blue and green colors represent small amounts of chlorine monoxide, while dark blue and black colors represent very large chlorine monoxide amounts. The white line marks the area within which the chemical ozone destruction took place. Image credit: NASA/JPL-Caltech

Excerpts;

The protective ozone layer in the Arctic that keeps out the sun’s most damaging rays, ultraviolet radiation, has thinned about 40 percent this winter, a record drop, the U.N. weather agency said Tuesday.

The Arctic’s damaged stratospheric ozone layer isn’t the best known “ozone hole,” that would be Antarctica’s, which forms when sunlight returns in spring there each year…
