Defence Minister Nelson Jobim said the government will increase the number of troops in the Amazon from 17,000 to 30,000 and build 28 new forts on Indian land and conservation areas of the world’s largest rain forest.
Pretty basic, but might be entertaining or informative for school children.
“Simply put, raising beef, pigs, sheep, chicken, and eggs is very, very energy intensive. More than half of all the grains grown in America actually go to feed animals, not people, says the World Resources Institute. That means a huge fraction of the petroleum-based herbicides, pesticides, and fertilizers applied to grains, plus staggering percentages of all agricultural land and water use, are put in the service of livestock. Stop eating animals and you use dramatically less fossil fuels, as much as 250 gallons less oil per year for vegans, says Cornell University’s David Pimentel, and 160 gallons less for egg-and-cheese-eating vegetarians.”

Cement, a vast source of planet-warming carbon dioxide, could be transformed into a means of stripping the greenhouse gas from the atmosphere, thanks to an innovation from British engineers.
“This spring, travelers entering San Francisco International Airport will see a new type of kiosk at check-in — one offering carbon offsets for those who wish to counter the greenhouse-gas emissions from their trip. It will be the first time that an airport will be peddling offsets, according to the San Francisco Chronicle.”
“The European Union’s new figurehead believes that climate change is a dangerous myth and has compared the union to a Communist state.
The views of President Vaclav Klaus of the Czech Republic, 67, have left the government of Mirek Topolanek, his bitter opponent, determined to keep him as far away as possible from the EU presidency, which it took over from France yesterday. ”
FriendsOfScience.com denies human agency in climate change, presenting themselves using a scientific argument and tone. For example:
‘MYTH 1: Global temperatures are rising at a rapid, unprecedented rate.
FACT: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures…’
Watching the video, it seems they are attributing climate change in part to the same extra terrestrial energy which gave the fantastic four their extraordinary powers: cosmic rays. They argue that when the solar wind is low, more cosmic rays reach the earth which can be shown to be correlated with cloud formation.

Looking at factors such as rapid sea ice loss in the Arctic and prolonged drought in the Southwest, the new assessment suggests that earlier projections may have underestimated the climatic shifts that could take place by 2100.
Carbon dioxide in earth’s atmosphere is considered a trace gas currently occurring at an average concentration of about 385 parts per million by volume or 582 parts per million by mass. The mass of the Earth atmosphere is 5.14×1018 kg, so the total mass of atmospheric carbon dioxide is 3.0×1015 kg (3,000 gigatonnes). Atmospheric concentrations of carbon dioxide fluctuate slightly with the change of the seasons, driven primarily by seasonal plant growth in the Northern Hemisphere. Concentrations of carbon dioxide fall during the northern spring and summer as plants consume the gas, and rise during the northern autumn and winter as plants go dormant, die and decay. Concentrations also vary considerably on a regional basis: in urban areas it is generally higher and indoors it can reach 10 times the background atmospheric concentration.
