THE CARBON DIOXIDE LEVEL IS DANGEROUSLY LOW

Posted: 1st April 2014

ACSC adviser David Archibald discusses the importance of more carbon dioxide in the atmosphere.

"The real threat is dangerously low levels of carbon dioxide in the atmosphere. The Earth has been in a glacial period for the last 3 million years, including some sixty separate glacial advances and retreats. The current Holocene interglacial period might last up to another 3,000 years before the Earth plunges into another glaciation. Carbon dioxide is a gas highly soluble in water, and its solubility is highly temperature dependent. The colder the planet is, the more carbon dioxide the oceans absorb. During glaciations the carbon dioxide level in the atmosphere has fallen to as low at 180 parts per million. It needs to be stressed that plant life shuts down at 150 parts per million, as plants are unable to operate with the partial pressure differential of carbon dioxide between their cells and the atmosphere. Several times during the last 3 million years, life above sea level was within 30 parts per million of being extinguished by a lack of carbon dioxide. The flowering plants we rely upon in our diet evolved 100 million years ago when the carbon dioxide level was four times the current concentration. For plant life, the current amount of carbon dioxide in the atmosphere is near starvation levels."

BIOFUELS DO MORE HARM THAN GOOD SAYS U.N

Posted: 1st April 2014

Robert Mendick from the U.K. Telegraph highlights yet another change in direction for the IPCC.

"A leaked draft of a UN report condemns the widespread use of biofuels made from crops as a replacement for petrol and diesel. It says that biofuels, rather than combating the effects of global warming, could make them worse.

The draft report represents a dramatic about-turn for the UN’s Intergovernmental Panel on Climate Change (IPCC).

Its previous assessment on climate change, in 2007, was widely condemned by environmentalists for giving the green light to large-scale biofuel production. The latest report instead puts pressure on world leaders to scrap policies promoting the use of biofuel for transport."

Those not weighed down with the burden of green ideology and groupthink only had to spend five minutes looking at the data when widespread use of first generation biofuels was mooted a decade ago to know it was a disaster in the making.

How many other issues is the IPCC going to reverse?  Before accepting the IPCC's advice,on which issues should governments have faith that the IPCC have got it right?

WINTER TEMPERATURES IN 20 YEAR COOLING TREND

Posted: 1st April 2014

James Taylor from the Heartland Institute looks at the data on winter temperatures from NOAA.

Winter temperatures in the contiguous United States declined by more than a full degree Celsius (more than 2 degrees Fahrenheit) during the past 20 years, National Oceanic and Atmospheric Administration data show. The data contradict assertions that human induced global warming is causing a rise in winter temperatures that alarmists say is causing an outbreak of bark beetles and other calamities.
