Obama science advisor wields evidence to undercut climate change deniers
October 5, 2010 09:47 AM - Jeremy Hance, MONGABAY.COM

US President Barack Obama's science advisor, John Holdren, took on climate change deniers in a comprehensive, data-heavy speech last month at the Kavli Science Forum in Oslo, Norway. Proclaiming that "the earth is getting hotter", Holden went on to enumerate on the causes of climate change (human impacts) and its overall effect (not good), discussing at length the science that underpins the theory of climate change.

The Future of Aviation: Confusion or Sanity
October 4, 2010 12:58 PM - Andy Soos, ENN

All industries across the world face the same regulatory maze and misdirection. In some cases it has led to industry leaving and going to China where laws are more permissive, That is not an option for the aviation industry which flies everywhere. All aviation stakeholders, including manufacturers, airlines, airports and navigation service providers, have issued a joint call for governments to agree a global plan to address aviation emissions at December's United Nations climate summit in Cancun.

Ancient Colorado River

Geologists have found evidence that some 55 million years ago a river as big as the modern Colorado River flowed through Arizona into Utah in the opposite direction from the present-day river. Writing in the October issue of the journal Geology, they have named this ancient northeastward-flowing river the California River, after its inferred source in the Mojave region of southern California.

Indonesia’s Climate Experiment
October 1, 2010 06:51 AM - Stephen Minas, The Diplomat

There's an easy charm to Banda Aceh that belies its tumultuous history—and a ground-breaking climate change experiment.Apart from the large ship washed kilometres inland that still towers over single-story homes, little evidence remains in the north Sumatran city of Banda Aceh of the devastation wrought by the Boxing Day tsunami in 2004, which claimed more than 230,000 lives. It's also hard to find traces of the bitter 30-year conflict between the separatist Free Aceh Movement and the Indonesian state that ended the following year there. Except, maybe, for one thing—an uptick in deforestation.

Disappearing Ground Water

The world's aquifers are being used faster than they can be replenished and, in some cases, at rates that have more than doubled since the 1960s. It is mostly agricultural irrigation that is driving the increase, because it accounts for 70 to 80 percent of global groundwater usage.

Deep Ocean Temperatures
September 24, 2010 02:44 PM - Andy Soos, ENN

There are many levels in the ocean. In some places it is very deep while in other sites there is only the shallow continental shelf. There have been several reports on global warming in terms of land and surface water temperature, Now come reports from deeper depths. Scientists analyzing measurements taken in the deep ocean around the globe over the past two decades find a warming trend that contributes to sea level rise, especially around Antarctica.

Coral Bleaching in the Caribbean
September 23, 2010 10:06 AM - David A Gabel, ENN

Due to above-average water temperatures in the Caribbean Sea, the National Oceanic and Atmospheric Administration (NOAA) predicts that coral bleaching will be very likely this year. It may even be as severe as 2005 when 80 percent of corals were bleached and 40 percent died. There have been reports from several sites already in the Caribbean as well as from other parts of the world.

Ocean cold snap paused global warming in 70s

A cold snap in northern oceans around 1970 may have caused a dip in world temperatures that briefly interrupted a trend of global warming, scientists said on Wednesday. Many experts had previously explained a slight global cooling around 1970 as a side-effect of a slow build-up of sun-dimming air pollution from factories, power plants and cars that cleared up in later years with stricter air pollution laws.

The Dusty Colorado River

Snow melt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study by NASA/UCLA shows this is due to increased dust caused by human activities in the typically arid American southwest region during the past 150 years.

Walrus Again Forced to Flee Melting Arctic Sea Ice
September 20, 2010 09:32 AM - Thomas Schueneman, Global Warming is Real

We first reported in 2007 of Walrus pushed off Arctic sea ice due to unusually low Arctic sea ice extent in the eastern Chukchi Sea, where they normally spend their summers breeding and feeding in the shallow waters of the continental shelf. For the third time in the past four years Walrus again find themselves forced onto land due to retreating sea ice.
