Now You Sea It, Now You Don’t: Watch Arctic Sea Ice Melt
Image Credit: NASA/Goddard Space Flight Center Scientific Visualization Studio
One of the most striking changes that has taken place in the Arctic since the start of satellite monitoring in 1979 is the rapid decline of the perennial sea ice cover. This ice is the sea ice that survives the summer melt season, and is typically the thickest part of the sea ice cover, sometimes spanning several years. Sea ice extent has declined as the globe has warmed, but the ice cover has thinned as well. Thinner sea ice melts more easily, and as multiyear sea ice is lost, Arctic sea ice has declined more rapidly.
This NASA visualization shows the perennial Arctic sea ice cover from 1980 to 2012. The grey disk at the North Pole indicates the region where no satellite data is collected. A graph overlay shows the area’s size measured in million square kilometers for each year. The ’1980′, ’2008,’ and ’2012′ data points are highlighted on the graph.
And here’s the video:

Surf champion Andy Irons dies of dengue fever
While traveling from Puerto Rico to his home in Hawaii, Andy Irons has died, so was confirmed by Surfer Magazine yesterday. Although the cause of death is still unknown, sources close to the family say he passed away as a result of dengue fever. Andy Irons was 3 times world champion and only 32 years old. He had a baby on the way and nothing could predict this horrible tragedy. So when I heard the news, I wanted to know more...
Do dams cause earthquakes in Japan?
Bad planning in the construction of dams in Japan makes the areas in which they are built more vulnerable to landslides and damage caused by earthquakes, argues environmental journalist Masano Atsuko. Tremors and volcanic eruptions are common on the Japanese archipelago and since much of the soil in certain regions is composed of tuff – a light, porous, rock formed from volcanic ash – mixed with other igneous rock, seismic activity can trigger landslides. In an article featured on the...
Oil news: The fight over offshore crude in the US and Brazil
When US President Barack Obama opened up large areas of America's Atlantic coastline to new oil drilling two weeks ago, some astute observers suggested that it might not be much more than a political maneuver. There is a distinct lack of knowledge concerning how much oil is out there; estimates put the amount of the Atlantic coast at 2 billion barrels (or 100 days of consumption) to 10 billion. According to a Newsweek article, it will be decades until we...
For all the feminists out there: First Lady descendant of Pocahontas
Yes you read it right, in American History there is a date to remember for all the feminists out there: September 25th, 1919. On that day not only was Edith Bolling Galt Wilson, descendant of Pocahontas, already First Lady of the USA; no on that day this Pocahontas offspring with very little formal education did, in fact, become what you could call the first American woman president. Her husband at the time, President Woodrow Wilson, who was giving a public speech...
Annual State of the Climate Report Says “Global Warming is Undeniable”
Last night, I was watching the Weather Channel and something rather interesting was brought to my attention. A new report on Global Warming was published recently. The report was written by more than 300 scientists from 48 countries and confirms what we’ve known all along: Global Warming is here and it’s not going anywhere, any time soon. Although the report (which is the 20th in a series) is mainly about Global Warming, it doesn’t cite any particular causes of it. However,...
A Study on Snails: Slow and Steady Wins the Race
When time (or anything else) seems to pass by at an extremely slow rate, you may hear someone comment that they just saw a stampede of snails pass them by. These little creatures may be slow and non-threatening, but they have come a long way and now, scientists are suggesting that their slowness may actually cause them to split into different species more rapidly. Apparently, when different populations of certain species stop mating with each other, they’ll begin to split into...
Nigeria: Children die from lead poisoning due to gold mining
Poor agricultural yields associated with climate change have forced some villagers in northern Nigeria to turn to other ways of survival. Many residents of this desperately poor region have turned to gold mining. But due to the high concentrations of lead found in the earth alongside potential gold deposits, people – especially children – are being poisoned. Factors such as intense poverty, increasingly unfavorable conditions for farming and soaring gold prices have combined and spurred residents of the Nigerian state of...
Of Ice and Men: Orville Schell likens America’s waning supremacy to the melting of Himalayan glaciers
Climate change as a metaphor – it is not only established in scientific terms, but now in literary form. As the Earth's atmospheric and surface climates change so do its political, economic and social climates; leaving at times an unrecognizable landscape. The Copenhagen summit offered hope for the climate and Barack Obama for American leadership – in spheres environmental and political – but they may both have come too little too late. That is the gist of journalist and scholar Orville...
Wonderful wildlife photography
Since tomorrow is International Biodiversity Day I thought I'd post some links to a few amazing galleries of wildlife photography that have been recently published online. First we have the Guardian's slideshow of 'New species discovered in Foja mountains on Indonesian island of New Guinea', including candid photos of a tame giant wooly rat, the smallest known member of the kangaroo family and a tiny tree mouse. Next, there's the Telegraph's piece on Belgian wildlife photographer and ecologist Guido Sterkendries, which features...
Brits are consuming less stuff
How about a spot of good news for once? According to environment writer and UK Green Party Candidate Chris Goodall, people in the UK probably consume fewer resources and produce less waste than at any time since records began. This means Britons are progressively using less food, fuel, goods, etc. – in short: less ‘stuff’. The amount of stuff consumed in the UK per person, per year, began to be tallied in 1970 and consumption peaked in 2001 before it started declining....
