Scientists have used satellite data from NASA-built Landsat missions to confirm that more than 20 years of warming temperatures in northern Quebec, Canada, have resulted in an increase in the amount and extent of shrubs and grasses.
Any work we have done in the past is done on the back of the research grants we get and has been well hidden. I’ve discussed this with the main funder [U.S. Dept. Of Energy] in the past and they are happy about not releasing the original station data
“His [model] is the most extreme but he is also the best modeller around,” he told the Telegraph’s Nick Collins. “It is really showing the fall-off in ice volume is so fast that it is going to bring us to zero very quickly. 2015 is a very serious pr
The first climate study to focus on variations in daily weather conditions has found that day-to-day weather has grown increasingly erratic and extreme, with significant fluctuations in sunshine and rainfall affecting more than a third of the planet.
The NOAA/NCDC chart represents the 15 years (180 months), starting November 1, 1996 and ending October 31, 2011. Per these latest U.S. official temperature data records, the 12-month period ending October was the 5th coldest October-ending period for
Thanks to research from his Berkeley Earth Surface Temperatures (BEST) project, Professor Muller stated confidently, we now know that the planet has warmed by almost one degree centigrade since 1950.
"While it is clearly premature to consider testing solar radiation management at a scale large enough to measure the climate response, it is not premature to understand what we can learn from such tests," said Doug MacMynowski of the California I
...Accused of Hiding Truth by Colleague
The Berkeley Earth Surface Temperature study finds reliable evidence of a rise in the average world land temperature of approximately 1°C since the mid-1950s. Analyzing temperature data from 15 sources, in some cases going as far back as 1800, the
Animals are shrinking and it may be due to climate change. So reads a new report from a team of Singapore scientists. First postulated by Charles Darwin as part of his adaptive theory of evolution, naturalists confirm that the phenomenon of animal sh
The global uptake of carbon by land plants may be up to 45 per cent more than previously thought. This is the conclusion of an international team of scientists, based on the variability of heavy oxygen atoms in the carbon dioxide of the atmosphere dr
The charlatans and zealots who promoted or allowed ecology to become the ultimate broad church gathering together everyone from the bird-watchers and butterfly collectors with their binoculars and nets, to the loopy militants chaining themselves to
Bitterly cold blasts of arctic air are expected to invade the northern Plains, Midwest and Great Lakes December through January, while snowfall averages above normal. "A couple of heavy hitters are possible [during this time]," Pastelok said in r
During extreme events, up to 70% of the ozone layer can be destroyed, before it recovers months later. The hole above the Arctic was always much smaller – until March this year, when a combination of powerful wind patterns and intense cold temperatur
Atlantic to the Pacific, has barely needed an ice-breaker since July as annual sea ice melted to a near record low extent. "We saved 1,000 tonnes of bunker fuel – nearly 3,000 tonnes of CO2 – on one journey between Murmansk and north China," said C
"Recent (ice shelf) loss has been very rapid, and goes hand-in-hand with the rapid sea ice decline we have seen in this decade and the increasing warmth and extensive melt in the Arctic regions," said Ted Scambos, lead scientist at the National S
Since then, the death rate has fallen by 99.9 percent. The study finds that global food production advancements, such as new crops, improved fertilizer, irrigation, and pesticides, along with society's better ability to move food and medical supplie
In previous generations, winter temperatures dropped to 40 degrees Celsius below freezing, while in present times temperatures only reach 25 C or 30 C below freezing. Moreover, in the rare case that temperatures did drop as low as they had in the pas
It amounts to a reluctant admission that global temperatures have indeed stalled. This fact has so far either been denied, ignored or buried beneath the claim that the past decade was still the hottest in the past 100 years (even if not by much).
According to the Canadian Ice Service, sea ice extent in the western Parry Channel has now reached the lowest at this time of year since record keeping began in 1966. Very little multi-year ice remains.
According to new research from MIT, the most recent global climate report fails to capture trends in Arctic sea-ice thinning and drift, and in some cases substantially underestimates these trends. The Intergovernmental Panel on Climate Change (IPCC
Average ice extent for July 2011 was 7.92 million square kilometers (3.06 million square miles). This is 210,000 square kilometers (81,000 square miles) below the previous record low for the month, set in July 2007, and 2.18 million square kilometers
A new kind of businessman has now arrived in the jungle. The Australian property developer David Nilsson is not seeking rubber or gold, but the carbon dioxide locked up in millions of hectares of lush Amazon rainforest east of Iquitos in Peru.
The Asian giant has been warned by one of its own groundwater experts to either cut its food production or else face "dire" waterlevels, especially in the dry northwest plains. If not, aquifers will sink to "dire" levels not seen in 30 years.
When Willi Dansgaard and Hans Oeschger discovered the 1,500 year cycle in the Greenland ice cores in 1984, they knew immediately that it was solar-powered. They’d seen exactly the same cycle in the carbon 14 molecules in trees, and in the beryllium 1
The area of the Arctic ocean at least 15% covered in ice is this week about 8.5 m sq kilometres – lower than the previous record low set in 2007 – according to satellite
In the two images above you can see the differences between the old normals (1971 to 2000) and the new normals. The top image shows changes in July maximum temperatures. The bottom shows changes in January minimum temperatures. Warmer temperature cha
"La Nina was strong in December," he says. "But back in January it pulled a disappearing act and left us with nothing - La Nada - to constrain the jet stream. Like an unruly teenager, the jet stream took advantage of the newfound freedom--and the
Coal-derived emissions pouring from smokestacks across Asia are--perhaps counterintuitively--responsible for a pause in global warming in the decade following 1998, but that’s no real reason to celebrate.
If present trends of a 1.5–2ppm annual increase in CO2 levels continue, there is little chance of stabilising greenhouse gas concentrations at 450 ppm. This would only result in a 50% likelihood of limiting global warming to 2C. Climate scientists sa
