)(Actual Report PDF
Actual global emissions of carbon dioxide (CO2) reached a new record of 34.5 billion tonnes in 2012. Yet, the increase in global CO2 emissions in that year slowed down to 1.1% , which was less than half the average annual increase of 2.9% over the last decade. This is remarkable, as the global economy grew by 3.5%. This development signals a shift towards less fossil-fuel-intensive activities, more use of renewable energy and increased energy saving. Increases in fossil-fuel consumption in 2012 were 2.2% for natural gas, 0.9% for oil products, and 0.6% for coal.

How can we get CO2 out of the atmosphere? Get it out of the sea first.
Making jet fuel from seawater
is a pretty cool -- albeit energy intensive -- trick. But applying the same science to scrub CO2 out of seawater, where it is more densely concentrated than in the atmosphere -- and, by doing so, to reduce atmospheric levels of CO2 back to acceptable levels -- that's a game saver.
"what would it take to draw atmospheric carbon down to 350 ppm with just this technology? . . . we would require the power of about 700 AP-1000 nuclear reactors. At the Chinese cost of $1.3b apiece and an 80 year lifetime this would cost a bit over $1 trillion dollars. That sounds like a lot of money. But its only about the cost of America’s 2003 Iraq War spread over the century, so I guess it’s a question of priorities."

design that saves mucho energy, does not require air conditioning, does not require heating even when outdoors it's 10 below!
Since, for example, more than 30% of energy consumed in the UK is for homes and 82 per cent of that is space and water heating, [Monbiot, "Heat,"chapter 5, "Our Leaky Homes,"] changing our standards of home design is important. Diagram
shows that basic solar design concepts are well understood and technically easy to implement in new construction. [If only my house could be turned 45 degrees!] Possibly through ignorance, and partly through the desire to cut corners instead of doing things right, we do not make these wise concepts a priority. There are lots of cool alternative
building techniques, many of which are traditional and being revived
. This leading design standard saves 90% of energy used in the home
. Here in Canada it's called the net zero energy home.

Will algae defeat global warming?
"Fed a generous helping of CO2-laden emissions, courtesy of the power plant's exhaust stack, the algae grow quickly... The cleansed exhaust bubbles skyward, but with 40 percent less CO2... The algae is harvested daily and a combustible vegetable oil is squeezed out: biodiesel".

of the mind
: Of kids, lies and Oil
. The American Petroleum Institute partners
with The National Science Teacher's
(NSTA) and Scholastic
(see: Scholastic's creedo
provide K-12 lesson plans, on energy and oil, which resemble the API's own "Teacher Lesson
and snappy flash presentations
such as Progress
which are bundled with fun stuff
cool facts. The NSTA/API lessons teach all about energy and oil except the global environmental impacts
. Didactic bonus from NSTA's
oil-friendly curriculum : a surrealistic gallery of oil industry
for kids to download.
