With the global total of emissions likely to come in at around 52 gigatonnes this year, we're already at the edge, according to new research
UXBRIDGE, Canada, Dec 17 2012 (IPS) - The most important number in history is now the annual measure of carbon emissions. That number reveals humanity's steady billion-tonne by billion-tonne march to the edge of the carbon cliff, beyond which scientists warn lies a fateful fall to catastrophic climate change.
With the global total of climate-disrupting emissions likely to come in at around 52 gigatonnes (billion metric tonnes) this year, we're already at the edge, according to new research.
To have a good chance of staying below two degrees C of warming, global emissions should be between 41 and 47 gigatonnes (Gt) by 2020, said Joeri Rogelj, a climate scientist at Switzerland's Institute for Atmospheric and Climate Science in Zurich.
"Only when we see the annual global emissions total decline will we know we're making the shift to climate protection," Rogelj told IPS.

The NCDC (an agency of NOAA) publishes global ocean temperature records, which confirm that global warming of the oceans did not cause Hurricane Sandy - in fact, their most recent temperature measurements reveal that ocean temperatures have actually remained flat over last 15 years (thru September 2012), while CO2 levels have increased

Paraphrasing Richard Feynman: Regardless of how many experts believe it or how many organizations concur, if it doesn’t agree with observation, it’s wrong.
The IPCC, some politicians and many others in the ‘consensus’ stubbornly continue to proclaim that increased atmospheric carbon dioxide (CO2) was the primary cause of global warming. Measurements demonstrate that they are wrong.
Some of their mistakes were discussed more than two years ago Mistakes made by the Consensus - climaterealists.com. The atmospheric carbon dioxide level has now increased since 2001 by an amount equal to 25.9% of the increase that took place from 1800 to 2001 (1800, 281.6 ppmv; 2001, 371.13 ppmv; Sept, 2012, 393.35 ppmv). The temperature trend, which was declining through 2009, was raised to flat through 2011 by the El Nino that peaked in March, 2010.

Al Gore teaching science to a gullible audience. (Image from film: An Inconvenient Truth)
Today website Die kalte Sonne tells us there’s a new paper appearing in the Geophysical Research Letters on the relationship of CO2 and temperature.
Let’s recall how Al Gore in his Oscar-winning An Inconvenient Truth proudly stood before the CO2-temperature curve of the last several hundred thousand years and fooled his gullible audience into thinking that CO2 drove global temperature in the past, and not vice versa.
Too bad Gore didn’t take a closer look at the curves. If he had, he would have noticed that temperature rose first with CO2 following, and so CO2 could not possibly have been the main driver. What really happened is that a warming Earth warmed the oceans, which in turn released CO2 into the atmosphere.
That’s the real inconvenient truth.

The past 5,000 years of the GISP2 temperature history of the Greenland Ice Sheet, adapted from Drake (2012), who denoted the general locations of the Late Bronze Age (LBA), the Roman Warm Period (RWP) and the Medieval Warm Period (MWP) in their original work.
While perusing a paper recently published in the Journal of Archaeological Science (Drake, 2012), we read the author’s account of how most of the Greek palatial centers of the Late Bronze Age were either destroyed or abandoned between the 13th and 11th centuries BCE, and how thereafter – during what has come to be known as the Greek Dark Ages – the people affected by this climatic cooling suffered significantly in multiple ways until the advent of the Roman Warm Period.

Temperature ranges: ESA spotted an anomolous cold region in the clouds of Venus, 140km above the surface
#Temperatures of -175C in high atmosphere suggests carbion dioxide 'snow' on Venus
#Follows recent discovery that Mars has flurries at the Northern Pole
#Planet has colder atmosphere than Earth - despite being closer to the sun
It may snow on Venus - although it will be snow composed of carbon dioxide, or 'dry ice'.
The European Space Agency's Venus Express satellite has spied a surprisingly cold region high in the planet’s atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow.
The planet Venus is well known for its thick, carbon dioxide atmosphere and oven-hot surface, and as a result is often portrayed as Earth’s inhospitable evil twin.

Runaway global warming gets more negative feedback
Salt marshes and similar types of coastal terrain could act naturally to fight global warming by absorbing increasing amounts of carbon in a warming world, scientists have found. Even better, salt marshes' carbon-sequestering effects would actually be increased sea-level rise.
Salt marshes, mainly made up of specialised grasses and their root systems, are a common type of coastal environment. They trap silt, serving to build up the elevation of the coastline and so resist storms and flooding. As the seas rise, the marsh rises too, as professor Matt Kirwan (Virginia uni) explains:
“One of the cool things about salt marshes is that they are perhaps the best example of an ecosystem that actually depends on carbon accumulation to survive climate change: The accumulation of roots in the soil builds their elevation, keeping the plants above the water,” says the prof.
According to a statement announcing Kirwan and his colleagues' new research into salt-marsh carbon effects:
