What global warming looks like
- Some amazing time lapse sequences of glacier retreat and a spectacular ice-shelf collapse: [more inside]
potholer54 is a youtuber who in his own words; I've been a journalist for 20 years, 14 years as a science correspondent. My degree is in geology, but while working for a science magazine and several science programs I had to tackle a number of different fields, from quantum physics to microbiology.
He has a series called Climate Change
that you might find interesting. [more inside]
"We badly underestimated the degree of damages and the risks of climate change,"
said Lord Stern in a speech in London yesterday. "All of the links
in the chain
are on average worse
than we thought (pdf)
a couple of years ago." [more inside]
New Jersey is drowning
, or rather it would if the the future as predicted by David Spratty & Philip Sutton in climate code red
comes true. Philip Sutton said in an interview
that "within five years the Arctic ice in the summertime will be all gone.". With all the ice melting, the waterlevels rise - will your house be under water?

of arctic sea ice extent, recorded from January to September 2007. [other formats]
This summer a dramatic decrease
compared to previous years in the extent of the north pole ice cap was observed. Scientists are freaked out [bugmenot]
. This summer, the Northwest Passage
was open for a few weeks, allowing three ships to traverse it. [more inside]
There has been a measurable "surge" of carbon
in the atmosphere for the past 4 or 5 years, nearly doubling the annual rate of the 1970-2000 period, which has mystified scientists because it does not match human trends or known natural causes. A new paper (abstract
) suggests we may have reached a tipping point
with more greenhouse gases escaping from trees, plants and soils than in the past - hotter and dryer weather caused by high levels of CO2 is creating a feedback loop of unusually strong out-gassings of CO2 from vegetation more inside
is closely linked
to climate. Although it observes an 11 and 22 year cycle
, the overall trend of activity shows much longer term variations
. The so-called Maunder Minimum
(1645-1715) coincided with the Little Ice Age
, while the Medieval Maximum
coincided with the Medieval Warm Period
. Analysis of beryllium isotopes
from ice cores in Greenland shows that sunspot activity is currently at a 1000 year high
. Could this account
, at least in part, for global warming? Recent data from Mars
suggests this may be so, while others remain sceptical

Is Cate Blanchett a global warming star or stinker? How about Angelina Jolie? Um, George Bush?
They got the money and the fame, but are they doing anything good with it, like maybe saving the planet.
Can you save the world?
This engaging flash game from the BBC lets you try. And it's based on Science! too.
. Penguin populations around the world are crashing. Biologists are mystified but suspect warmer oceans caused by global warming is reducing available food.
The Weather Channel launches One Degree
, a broadband channel dedicated to global warming - for the "weather obsessed", sexy-voiced climatologists Heidi Cullen brings global warming mainstream. Are you a "climatechanger"?
President Bush is preparing an astonishing U-turn
on global warming, senior Washington sources say.
Fair Price Energy
. One persons idea for a free market solution to the fossil fuel problem.
The Amazon rainforest becomes "a desert"
after three consecutive years without rain - the trees die. Next year would be the third year of an ongoing drought
. The forest contains 90 billion tons of carbon (or about 45 years of stored human emmisions at current rates
) - 3/4's of the carbon is released within a year of dieing. The Amazon is "headed in a terrible direction".
Who'll be living where. Researchers at the Earth Institute at Columbia University have developed map
that projects where people will be living in the year 2025.
the new urban jungle
. . . is a growing movement led by cities like San Francisco
, New York
, and Leiden
to restore active and vibrant natural systems in urban areas. Far from the eden-like depictions of nature of yesteryear, i.e. the garden of earthly delights
(nonetheless, still attracting some dynamic new christian converts
), the movement has morphed into today's backyard and grassroots environmental movement which is more and more a picture of hybridity, compromise, mixed-use, and ultimately, taking nature out of the walled islands of zoos, aquaria, national parks and other thick-walled institutions and offering a different kind of everyday "unmediated"
community experience with the new urban wilderness
Global warming underestimated by up to 78%.
Scientists analyzing historical climate data for Europe have established the existence of a greater-than-anticipated positive feedback mechanism between high temperatures and global carbon dioxide levels. This provides more scientific evidence to support previously-expressed concerns
that as global warming intensifies, a chain-reaction of considerably higher temperatures may occur. This corresponds with a new report released by the Australian government
, claiming that "there is now perceived to be a greater risk that the upper end of the well known IPCC TAR estimate of a 1.4 to 5.8°C temperature rise will be reached or exceeded by 2100."
"Estimates of future warming . . . may have to be raised by about 50 percent."
are on the rise. Flood Maps
mashes up NASA elevation data and Google Maps, and offers a zoomable localized visualization of the effects.
The Coming Meltdown
. The incredible story
of Lonnie Thompson
- West Virginia conservative, world-class mountaineer, glaciologist, and leading climatologist who first told Congress the world is heating up in 1988, "the moment at which the greenhouse era really began".
No surprise: Warmest September (globally) since record keeping began
, according to NOAA, 1.13 degrees above the 1880-2004 long term mean, with land temperatures more than 5 degrees F above normal across large parts of Asia and North America. Ocean temperatures were third highest on record.
Scientists find errors in global warming data.
Heating from tropical sunlight was skewing temperatures reported by satelite sensors, making nights look as warm as days. The George C. Marshall Institute
declined to comment. The group, financed by the petroleum industry, has used the data disparities to dispute the views of global-warming activists. Researchers say it removes a last bastion of scientific doubt about global warming
is the largest experiment ever to try and produce a forecast of the climate in the 21st century. it's a collaborative project a la seti@home
, and they have come up with some interesting results
we've heard about climate change before
, but this study indicates that things might be significantly worse than initially thought (double the temperature increase as previously predicted).
maybe this is all okay though, even good for you
. if you'd like to see that idea nicely debunked, i suggest you check out trust us, we're experts
. a lovely little book about how much we can trust all of these studies.
makes you wonder if we should have signed this
