Real Climate Science

I took the radiate transfer model used by NCAR (RRTM) and ran it with tropical humidity (0.025 mole fraction H2O)  and three levels of CO2. Results are shown below.

1. 0 ppm   392.3 w/m²
2. 364 ppm   397.5 w/m²
3. 3640 ppm   403.8 w/m²

CO2 contributes almost nothing to the greenhouse effect in the tropics. The removal of all CO2 would only lower downwelling longwave radiation by 1.3%. A 10X increase in the amount of CO2 would only increase downwelling longwave radiation by a little over 1%.

At lower surface humidity (0.015 mole fraction H2O), co2 contributes about 2.5% of the greenhouse effect.

1. 0 ppm   372.8 w/m²
2. 364 ppm   381.3 w/m²

The role of CO2 is wildly exaggerated by alarmists. Gavin typically uses a number somewhere around 30%, when in fact the real number is less than 5% over most of the Earth’s surface.

Scientists knew a century ago that continents had to move, and that major climate change was natural. It took many decades for the consensus to accept continental drift, and the “consensus” still claims that climate change is man made.

Conclusion : the hockey team is probably the stupidest group of scientists in history.

Green energy means stealing green bills from taxpayers wallets.

In December, the Navy purchased 450,000 gallons of biofuels at $26.75 a gallon, POLITICO Pro reported. In comparison, the cost of petroleum is just a few dollars per gallon.

Inventor says that we would have already fried, except for the aerosols which we already cleaned up.

Global warming worse than it appears: Nobel Prize laureate English.news.cn   2012-06-21 19:55:19

RIO DE JANEIRO, June 21 (Xinhua) — Carlo Rubbia, who shared the 1984 Nobel Prize in physics, says global warming is a much bigger problem than most people realize. “My message is that the situation is much worse than one sees and believes,” Rubbia, an Italian particle physicist and inventor, told Xinhua in an interview on the sidelines of the U.N. Conference on Sustainable Development (Rio+20 Earth Summit). Rubbia mentioned two “contradictory phenomena” — global warming and the aerosol masking effect which effectively offset the effects of the former.

Otherwise, the temperature of the Earth would have increased to about three degrees centigrade by now, he said. “The man in the street does not realize the effects of climate change,” because in the last 10 years, the temperature did not increase substantially. So “people feel the pressure of global warming is not a reality,” he said.

In other words, this guy has some invention he wants to sell – but needs to make a few government officials extremely stupid before he can close the sale.

One even days, we are told that the global cooling scare was due to aerosols which we subsequently cleaned up. On odd days, we are told that we didn’t clean up the aerosols, and they are 10 times worse than we thought.

Drastic changes needed to curb N2O, most potent greenhouse gas

Meat consumption in the developed world needs to be cut by 50 per cent per person by 2050 if we are to meet the most aggressive strategy, set out by the Intergovernmental Panel on Climate Change (IPCC), to reduce one of the most important greenhouse gases, nitrous oxide (N2O).

Drastic changes needed to curb N2O, most potent greenhouse gas: study

Complete BS. Nitrous oxide makes up much less than one part per million in the atmosphere, and has only a few narrow absorption bands – which overlap with CO2 and water vapor. The percentage of the greenhouse effect on earth produced by nitrous oxide is very close to zero. These clowns need to stop inhaling whip cream.

80 degrees of global warming in five days in 1934. Hansen would have declared this to be impossible without the emissions from your SUV.

1934: What would become one of the hottest summers on record in Iowa began to intensify as a heat wave in the last three days of May resulted in nearly every location in the state exceeding 100 F on at least one of those three days. The heat wave peaked on the 30th when the temperature soared to as high as 111 F near Inwood which is the highest temperature ever recorded in Iowa in May. Other high temperatures on the 30th included 110 F at Boone, 109 F at Logan and Spencer, 108 F at Le Mars, and 107 F at Storm Lake. Des Moines and Sioux City also set their respective May records as both reached a high of 105 F. Amazingly this extremely hot weather came only a few days after unseasonably cool temperatures in the 30s had been recorded across much of the state with frost on the 25th and 26th. In fact, at Boone the low temperature on the morning of the 25th was 30 F so the temperature at that location rose by 80 F in just five days. To put this into perspective, the largest temperature range ever recorded across the state of Iowa during the entire month of May is 88 degrees.

Study: Global warming could bring penguins to brink of extinction

If global temperatures continue to rise, however, the Emperor penguins inTerre Adélie, in East Antarctica may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution

Complete bullshit. Temperatures in East Antarctica have cooled, and sea ice has steadily increased. Much of the claimed 0.6C global warming has been winter temperatures at high northern latitudes. How is that supposed to affect Penguins in Antarctica?

Global warming may have another victim in its sights: the penguin.

According to newly released report, penguins are facing an intangible threat that may ultimately decimate the population.

A study produced by several Boulder researchers notes that penguin populations could decline by as much as 60 percent. The team noted that a series of recent observations showed that the penguin population is already witnessing a steep decline in numbers.

Hopefully the money for phony Boulder scientists will drop by 100%.

“Over the last century, we have already observed the disappearance of the Dion Islets penguin colony, close to the West Antarctic Peninsula,” says Stephanie Jenouvrier, WHOI biologist and lead author of the study. “In 1948 and the 1970s, scientists recorded more than 150 breeding pairs there.”

She notes that within the past ten years the population has nearly vanished, a disturbing sign that global warming may be forcing the birds to migrate elsewhere.

Exactly. The birds moved their colony elsewhere. One study of one small local population tells nothing about the overall population of the species.

“By 1999, the population was down to just 20 pairs, and in 2009, it had vanished entirely,” said Ms. Jenouvrier.

Cook goes full stupid and shoots himself in the foot.

He argues that Hansen’s predictions failed because humans have greatly reduced their output of GHG’s other than CO2. He also argues that CO2 is a minor component relative to the other man-made GHG’s.

the main difference between the various Hansen emissions scenarios is not due to CO2, it’s due to other greenhouse gases (GHGs) like chlorofluorocarbons (CFCs) and methane (CH4), whose emissions have actually been below Scenario C (Figure 1).  In fact, more than half of the Scenario A radiative forcing comes from non-CO2 GHGs.

Simply Wrong: Jan-Erik Solheim on Hansen 1988

Cook is claiming that the most important greenhouse gases have been reduced by more than 80% below what Hansen forecast.

Then he produces a graph showing that temperatures are below Scenario C.

This is what Hansen said about Scenario C :

“Scenario C assumes … that the net climate forcing ceases to increase after the year 2000”

In summary, Cook is arguing that man has already cleaned up the most important GHG’s, and that temperatures are lower than if man had produced no GHG’s since the year 2000. We can conclude from his argument that the world has far exceeded its Kyoto GHG reduction targets, and that temperatures are rising very slowly.

Time for everyone to come home from Rio, and find a different way to repress and rob the citizenry.

Gavin and Jim want you to believe that Scenario B is the right one, because Scenario B’s predictions didn’t suck quite as bad as Scenario A. But it is worse than it seems.

The CO2 curve is an exponential curve. Joe Romm described it as being “super-exponential” The curvature is upwards, which means that the second derivative is positive.

The graph below adds tangents, showing how the slope is getting progressively steeper.

Jim and Gavin naturally assume that their audience is gullible, and have been pushing the Scenario B meme. So let’s look at what Hansen actually wrote in his 1988 paper.

pubs.giss.nasa.gov/docs/1988/1988_Hansen_etal.pdf

Scenario A assumes exponential growth of CO2. Scenario B assumes linear growth, which clearly is not the case. Scenario C assumes no growth.

The graph below shows what Hansen’s three scenarios would have looked like. Scenario A in blue, Scenario B in green, and Scenario C in red.

According to NASA’s top experts, the Arctic may be ice-free by the summer of 2012. An ice-free Arctic would require that the ice edge melts back about 20 miles a day, for the next ten weeks.

That could happen if aliens aim a giant blow torch at the North Pole. Only an evil denier would question the word of a NASA climate expert.
