"In an enormous display of survival of the fittest, the forests of the future are taking a new shape. In a new report, scientists outline the impact that a changing climate will have on which tree species can survive, and where. The study suggests that many species that were once able to survive and thrive are losing their competitive footholds, and opportunistic newcomers will eventually push them out."

Skeptics vs Proponents of Human Activity Driving Climate Change

"The upper layer of the world's ocean has warmed since 1993, indicating a strong climate change signal, according to a new study. The energy stored is enough to power nearly 500 100-watt light bulbs per each of the roughly 6.7 billion people on the planet."

Bill Nye and the Discovery Channel give you the greatest discoveries in science. Earth is always changing, and Earth's species must continually adapt. Host Bill Nye gives an inside look at planet Earth, from its inner core to its protective magnetic field. Discover how earthquakes and volcanoes help explain plate tectonics and the dynamic geology of oceans and continents. Learn how the Earth's atmosphere gives scientific insight about weather and climate, and look at forms of radiation and the potential dangers from harmful gases and geologic changes.

"Claims that the costs of wind farms and other low-carbon technology will lead to sharp rises in fuel bills are wrong, government advisers say. The Committee on Climate Change (CCC) says increases in bills over the past few years have been largely due to higher wholesale gas costs."

It was the year we learned of a spectacular smash-up in space, and scientists working on the world's biggest physics experiment delighted at collisions of an entirely different sort. There were shockwaves, too, in Copenhagen, as the summit failed to reach a consensus on tackling climate change, instead merely noting a deal struck by major powers including the US and China. The BBC's science reporter Paul Rincon looks back at the twists and turns of a year in science and the environment.

Arctic temperatures are now higher than at any time in the last 2,000 years, research reveals. Changes to the Earth's orbit drove centuries of cooling, but temperatures rose fast in the last 100 years as human greenhouse gas emissions rose. Scientists took evidence from ice cores, tree rings and lake sediments.

"In this bracing talk, coral reef ecologist Jeremy Jackson lays out the shocking state of the ocean today: overfished, overheated, polluted, with indicators that things will get much worse. Astonishing photos and stats make the case."

"Think of the ocean as our global savings account -- and right now, we're only making withdrawals, not deposits. Enric Sala shows how we can replenish our account through no-take marine reserves, with powerful ecological and economic benefits."

"Researchers are finding that food miles are far from the whole story when assessing the environmental impact of what we eat. At a conference last month on the economics of food, Chris Foster of Manchester Business School presented some startling conclusions from a review of the evidence. "
