Arctic temperatures warmest in over 10,000 years

Arctic temperatures are the warmest in more than 10,000 years, speeding the thaw of permafrost in Canada’s North, shows climate research out of the University of Alberta.

“We’ve known that the last few decades have been very warm. But we’ve found that temperatures are on the order of two degrees Celsius warmer than any time in the last 10,000 years — that was a surprise,” Duane Froese, professor in the Department of Earth and Atmospheric Science, and Canada Research Chair in Northern Environmental Change…

❝ The study found that previous record highs occurred during the early Holocene period — around 9,900 and 6,400 years ago. But even without the unique circumstances of that period, when the Earth’s axis was more strongly directed toward the sun, current Arctic temperatures have exceeded those records.

“All indications from this new study are that temperatures and the impacts of recent warming are only picking up and getting stronger,” said Froese. “We are moving into uncharted waters with respect to climate change in the North.”

Gee, I hope this doesn’t upset the Trump supporters who are dedicated to searching for “science” that backs the fantasies of their Great Leader.

WMO measures greenhouse gases at record levels

Concentrations of the main greenhouse gases in the atmosphere have reached their highest level since pre-industrial times, the World Meteorological Organization has said…

The main long-lived greenhouse gases including carbon dioxide, methane and nitrous oxide have reached their highest recorded levels since the beginning of the industrial age, and this despite the recent economic slowdown,” WMO Deputy Secretary-General Jeremiah Lengoasa told a briefing.

The findings will be studied at a U.N. meeting in Cancun, Mexico, from November 29 to December 10 to discuss climate change.

Total radiative forcing of all long-lived greenhouse gases — the balance between radiation coming into the atmosphere and radiation going out — increased by 1.0 percent in 2009 and rose by 27.5 percent from 1990 to 2009, the WMO said.

The growth rates for carbon dioxide and nitrous oxide were smaller than in 2008, but this had only a marginal impact on the long-lasting concentrations…

Carbon dioxide is the single most important greenhouse gas caused by human activity, contributing 63.5 percent of total radiative forcing. Its concentration has increased by 38 percent since 1750, mainly because of emissions from burning fossil fuels, deforestation and changes in land use, the WMO said.

Natural emissions of methane due for example to the melting of the Arctic icecap or increased rainfall on wetlands — themselves caused by global warming — are becoming more significant, it said.

This could create a “feedback loop” in which global warming releases large quantities of methane into the atmosphere which then contribute to further global warming.

Yes, I know it seems to be too difficult a task for many to comprehend time beyond the next 2 quarters much less a few centuries. Geologic time fits only into the rationalization scheme of some ideologies.

Treating the “Age” of industrialization as comparable to prehistoric epochs only works for those whose skull shape matches their perception of the Earth’s geometry.

Spanish bank notes contain highest traces of cocaine in Europe

A study of randomly selected Spanish euro notes carried out by chemists at the University of Valencia has shown that they contained traces of cocaine at an average concentration of 155 microgrammes, which is the highest rate in Europe.

“The latest technology means we can now carry out quantitative analysis of cocaine traces on any bank note, and as a result we can confirm that – at least in Spain – traces of the drug are found not only on notes that have been in direct contact with it, but on nearly all the notes in circulation,” said Miguel de la Guardia, co-author of the study. He explained that this was due to “cross contamination” between bank notes, as well as in money counting machines used by banks.

The study also analyses previous studies highlighting the concentrations of cocaine found in different currencies around the world, as well as the results of the random sample of Spanish bank notes gathered by the Valencian chemists, which detected concentrations of up to 889 microgrammes of the drug on some notes.

In the United States, which has the most highly contaminated bank notes of any country in the world, dollar bills containing more than 1,300 microgrammes of cocaine have been registered, although the average values were between 2.86 and 28.75 microgrammes, varying according to the year and city.

Phew! Is this how and why Spain won the Euro 2008 football tourney?
