Earth Is Headed for Disaster, Interdisciplinary Scientific Review Concludes
An interdisciplinary group of 22 scientists, combining paleontological evidence with ecological modeling, has concluded that the earth appears headed toward catastrophic and irreversible environmental changes.
Their report, in the June 7 issue of the journal Nature, describes an exponentially increasing rate of species extinctions, extreme climate fluctuations, and other threats that together risk a level of upheaval not seen since the large-scale extinctions 65 million years ago that killed off the dinosaurs.
...
Their conclusion is that the damaging effects, when combined, appear even worse than each of the experts has seen in his or her own field, Mr. Barnosky said. "These are all driving forces that in fact are greater than what we saw in the past," he said.
...
But for others, the warning contained in the Berkeley-led report may not be strong enough. "I suspect it's a little too optimistic," said Paul R. Ehrlich, a professor of population studies at Stanford University known for his 1968 book The Population Bomb.
Mr. Ehrlich said he foresees a series of dire threats to humanity, many virtually untouched by political leaders, including climate change, water shortages, and the widespread use of man-made toxins. Even a single repercussion of one of those, such as water scarcity leading to nuclear war between India and Pakistan, could devastate populations worldwide, he said.
"Generally the scientific community has spoken many times," Mr. Ehrlich said, "but nobody's paying any attention."

This is probably nothing to worry about (cont'd)
Using computer modeling and observations, researchers concluded that carbon dioxide emissions have already raised ocean acidity far beyond the range of natural variations. Meaning, that oceans have acidified more in the last 200 years, than they did in the previous 21,000 years.

This marks the 35th straight year that global temperatures were warmer than normal. NOAA's records for world average temperatures date back to 1880.

I guess what's been killing the bees should have been obvious


If they need to find a healthier way to cope with all that bee stress, I suggest booze.
Apparently, neonicotinoids are "a group of toxic chemicals designed to paralyse insects by attacking their nervous systems." But, as it turns out, bees are insects too. Hmmph. And you spelled "paralyze" wrong.
Nicotine-based pesticides in widespread use by farmers are implicated in the mass deaths of bees, according to a new study by US scientists.
The authoritative, peer-reviewed research undermines the pesticide industry's long-repeated arguments that bees are not being harmed, and piles pressure on UK and US authorities to follow other countries by introducing bans on the chemicals.
Pesticide companies have been trying to protect their multi-billion pound businesses by lobbying internationally against bans on neonicotinoids, a group of toxic chemicals designed to paralyse insects by attacking their nervous systems.
Agricultural crops in Scotland, England and around the world are dosed with the chemicals to prevent insects from damaging them. But evidence has been mounting that they could be to blame for the "colony collapse disorder" that has been decimating bee populations.
The US has been losing one-third of its honeybee hives every year, while beekeepers in Europe say that more than one million bee colonies have been wiped out in France, Germany, Italy and the UK since 1994.
Although neonicotinoids have faced bans or restrictions in Germany, France, Italy and Slovenia, regulators in the UK and the US have so far accepted the industry's contention that the toxins were not poisoning bees.
But that view has now been seriously challenged by a new study from scientists at Purdue University in West Lafayette, Indiana. They found neonicotinoids in bees, in pollen, in soil and in dandelions, suggesting that bees could be contaminated in several different ways.
"We know that these insecticides are highly toxic to bees; we found them in each sample of dead and dying bees," said Christian Krupke, associate professor of entomology at Purdue and a co-author of the study. Bees also suffered from tremors, unco-ordinated movement and convulsions, which are all signs of insecticide poisoning...
