babble is rabble.ca's discussion board but it's much more than that: it's an online community for folks who just won't shut up. It's a place to tell each other — and the world — what's up with our work and campaigns.

Simultaneous warming events in the northern and southern hemispheres [such as we have at present], have not occurred in the past 20,000 years, which is as far back as it is possible to analyse with sufficient precision to compare with modern developments. Svante Björck’s study thus goes 14,000 years further back in time than previous studies have done. “What is happening today is unique from a historical geological perspective”, he says. Source

The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000....

The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline.

“We know the planet is absorbing more energy than it is emitting,” said GISS director James E. Hansen. “So we are continuing to see a trend toward higher temperatures. Even with the cooling effects of a strong La Niña influence and low solar activity for the past several years, 2011 was one of the 10 warmest years on record.”...

The only year from the 20th century in the top 10 warmest years on record is 1998.

New IPCC report warns of increases in extreme weather events

Quote:
Global warming is leading to such severe storms, droughts and heat waves that nations should prepare for an unprecedented onslaught of deadly and costly weather disasters, an international panel of climate scientists said in a new report [20-page summary] issued Wednesday.

The greatest threat from extreme weather is to highly populated, poor regions of the world, the report warns, but no corner of the globe — from Mumbai to Miami — is immune.

The document by a Nobel Prize-winning panel of climate scientists forecasts stronger tropical cyclones and more frequent heat waves, deluges and droughts. [5-minute YouTube video]

The 594-page report blames the scale of recent and future disasters on a combination of man-made climate change, population shifts and poverty.

In the past, the Intergovernmental Panel on Climate Change, founded in 1988 by the United Nations, has focused on the slow inexorable rise of temperatures and oceans as part of global warming. This report by the panel is the first to look at the less common but far more noticeable extreme weather changes, which lately have been costing on average about $80 billion a year in damage.

NASA Scientist: Climate Change is a Moral Issue on a Par With Slavery

http://www.guardian.co.uk/environment/2012/apr/06/nasa-scientist-climate...

"...We can't simply say there's a climate problem and leave it to the politicians. They're so clearly under the influence of the fossil fuel industry that they're coming up with cockamamie solutions which aren't solutions. That is the bottom line.."

Canada's PM Stephen Harper faces revolt by scientists

The Guardian wrote:
Canada's prime minister, Stephen Harper, faces a widening revolt by the country's leading scientists against sweeping cuts to government research labs and broadly pro-industry policies.

The scientists plan to march through Ottawa in white lab coats on Tuesday in the second big protest in a month against the Harper government's science and environmental agenda.

Harper is accused of pushing through a slew of policies weakening or abolishing environmental protections - with an aim of expanding development of natural resources such as the Alberta tar sands.

His government is also accused of jeopardising Canada's scientific reputation by shutting down the Experimental Lakes Area (ELA), a research station that produced critical evidence to help stop acid rain.

The Disaster that Made the Modern World

Two centuries later, with our changing climate, Tambora's power still haunts us.

  • The Year Without Summer: 1816 and the Volcano that Darkened the World and Changed History
  • William K. Klingaman and Nicholas P. Klingaman
  • St. Martin's Press (2013)

While we are undoubtedly changing climate, climate is changing us.

The warming of the last 50 or 60 years is likely the root cause of the low-grade civil wars that have been flaring up in the belt just south of the Sahara, from northern Nigeria to South Sudan and the Horn of Africa. Australia is adapting to a new regime of droughts and bushfires followed by rains and floods. Dengue fever is returning to Florida.

Here in B.C., we've seen our forests turn into a pine-beetle utopia, and climate change may finish off the wild salmon regardless of fish farms. Our governments are doing as little as possible about it.

Like St. Augustine praying for release from his sexual urges, we dream of a future without fossil fuels -- "But not yet, O Lord!" Clearly our changing climate will eventually impose fossil-fuel celibacy on us whether we're ready or not, and that will mean extremely difficult political and economic decisions.

Two hundred years ago, climate change drove politics in ways the politicians of the day didn't even recognize. But their responses helped create our world.

The agent of climate change in 1816 wasn't carbon dioxide; it was the Indonesian volcano Tambora. When it erupted in April 1815 it threw 55-million tons of sulfur dioxide into the stratosphere. There it converted into sulfuric acid and spread in tiny droplets around the world, screening a small percentage of sunlight.
