Climate Change Is Forcing Trees to Move Northwest - The Atlantic. As the consequences of climate change strike across the United States, ecologists have a guiding principle about how they think plants will respond.
Cold-adapted plants will survive if they move “up”—that is, as they move further north (away from the tropics) and higher in elevation (away from the warm ground). A new survey of how tree populations have shifted over the past three decades finds that this effect is already in action. But there’s a twist: Even more than moving poleward, trees are moving west. About three-quarters of tree species common to eastern American forests—including white oaks, sugar maples, and American hollies—have shifted their population center west since 1980.
More than half of the species studied also moved northward during the same period. The Great Barrier Reef: a catastrophe laid bare.

A fisherman shovels grey sole, a type of flounder, out of the hold of a ship at the Portland Fish Pier in Maine, September 2015.
New research finds the ability of fish populations to reproduce and replenish themselves is declining across the globe. The worst news comes from the North Atlantic, where most species are declining.

While this sawing-through-the-branch-we’re-perched-on is largely unintentional, world leaders can’t say they didn’t know what’s going on: 123 countries promised to take urgent action in 2003 but have done little to stem the rising tide of extinctions in what’s known as the extinction or biodiversity crisis. Species are going extinct at 1,000 times their natural pace due to human activity, recent science has documented, with 35 to 40 species vanishing each day, never to be seen again.
“The question of preserving biological diversity is on the same scale as climate protection,” German Chancellor Angela Merkel said in a speech in Berlin Monday at the official launch of the United Nations’ International Year of Biodiversity. The Latest Buzz on Bees. Illustration by Rafael Ricoy A beekeeper's discovery could help save our honeybees from a massive die-off About five years ago, researchers studying colony collapse disorder, the syndrome in which most of the honeybees in a colony die or disappear without warning, discovered a new potential culprit: a fungal pathogen called Nosema ceranae.
While they didn't believe it was the sole cause of colony collapse disorder, or CCD, evidence suggested that it played a part in this epidemic, which has had severe effects on American agriculture. (Honeybee pollination is responsible for a third of the food we eat; crops that rely on it are valued at $15 billion annually.) Dealing with the consequences of climate chance inaction: the impact of food - History Future Now. In a previous article History Future Now admitted defeat: climate change is happening and there is no viable political solution which will enable us to stop it from getting worse.
Global average temperatures will rise beyond the 2 degrees that politicians have determined is the absolute maximum that it should be allowed to increase by. Climate Change Is Turning Your Produce Into Junk Food. Alan Roelofs examines a soybean field on his farm near Tyler in southwest Minnesota in an undated photo.

Climate skeptics like to point out that carbon dioxide in the atmosphere stimulates plant growth — suggesting that ever-growing fossil fuel consumption will lead to an era of bin-busting crop yields. Biodiversity: Life – a status report. Of all the species that have populated Earth at some time over the past 3.5 billion years, more than 95% have vanished — many of them in spectacular die-offs called mass extinctions.
On that much, researchers can generally agree. Yet when it comes to taking stock of how much life exists today — and how quickly it will vanish in the future — uncertainty prevails. Studies that try to tally the number of species of animals, plants and fungi alive right now produce estimates that swing from less than 2 million to more than 50 million. Earth lost 50% of its wildlife in the past 40 years, says WWF. The number of wild animals on Earth has halved in the past 40 years, according to a new analysis.
Creatures across land, rivers and the seas are being decimated as humans kill them for food in unsustainable numbers, while polluting or destroying their habitats, the research by scientists at WWF and the Zoological Society of London found. “If half the animals died in London zoo next week it would be front page news,” said Professor Ken Norris, ZSL’s director of science. Researcher says sixth mass extinction is here. Stanford Report, June 19, 2015 Paul Ehrlich and others use highly conservative estimates to prove that species are disappearing faster than at any time since the dinosaurs' demise.
