The number of people living in extreme poverty could increase by up to 3 billion by 2050 unless urgent action is taken to tackle environmental challenges, a major UN report warned on Thursday. The 2013 Human Development Report hails better than expected progress on health, wealth and education in dozens of developing countries but says inaction on climate change, deforestation, and air and water ... read more >>
U.N. agencies want to strengthen national drought policies after warnings that climate change would increase their frequency and severity. Droughts cause more deaths and displacement than floods or earthquakes, making them the world's most destructive natural hazard, according to the Food and Agriculture Organisation, one of the groups taking part. "We must boost national capacity to cope before ... read more >>
Canadian artist Serge Belo has created what he says is the world's largest water mosaic, to raise awareness about the shortage of clean water globally. The result is a mosaic spanning 334 sq m, using 15,000 litres of coloured rainwater. He used 66,000 cups of water to simulate the impurities found in water all over the planet. ... read more >>
This May 24, 2011 file photo shows the path of a powerful tornado through Joplin, Mo. In 2011, the United States saw one of the busiest tornado seasons in generations: Nearly 1,700 tornadoes that killed 553 people. With the planet heating up, many scientists seem fairly certain some weather elements like hurricanes and droughts will worsen. But as the traditional season nears, scientists are stil ... read more >>
The dry, barren prairie around Alberta's Drumheller area was once a lush and subtropical forest on the shores of a large inland sea, with loads of wetlands inhabited by dinosaurs, turtles, crocodiles and small mammals.
But that changed about 71-million-years ago, according to a new study by researchers Annie Quinney and Darla Zelenitsky in paleontology at the University of Calgary. The researc ... read more >>
A lot of smart people are coming to see the energy problem as the defining challenge of the 21st century. We have to supply power and transportation to an eventual population of 10 billion people who deserve decent lives, and we have to do it while limiting the emissions that threaten our collective future.
Yet we have already poured so much carbon dioxide, the main greenhouse gas, into the atmo ... read more >>
Those are daunting goals. They’re also in somewhat awkward tension with each other. The first requires increasing the amount of energy the world uses, including fossil fuels. The second requires harnessing cleaner power sources, using energy more efficiently, and even conserving power. So is it possible to do both at once?
The U.N. certainly thinks so. Last year, Secretary-General Ban Ki Moon un ... read more >>
For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.
Since the beginning of the indus ... read more >>
Fifteen years after the Kyoto protocol was signed and just months after being extended, a true global carbon trading marketplace may finally be within the world's grasp. It is as though a line of dominos has suddenly appeared, awaiting the slightest push to set off a chain reaction. When the dominos begin to fall, the world will suddenly have a powerful and effective tool to reduce carbon emissio ... read more >>
