As a minor followup to my post “Could CO2 have lowered the rate of natural warming?” lets consider ocean warming.
From 1900 to 1945 oceans were warming at a rate of 0.0116188C per year.
After 1945 oceans were warming at a rate of 0.00654978C per year.
Which means the massive 1945 increase in CO2 after 1945 slowed the rate of ocean warming by 0.00506902C per year. Which is a drop off 44%.
Woodfortrees Url is here.
Lets say you have a pot of water that is warming, but you can’t see underneath it. There is a thermometer in the pot, and intermittently you write down the temperature.
And at some point some people come up with a theory that suggests a 2nd candle is now adding its energy to the pot of water. So what are you going to do?
Well, one way is to take the temperature data and graph it and calculate the trend before and after the supposed appearance of the 2nd candle. The change in trend is possibly the extra energy added by the 2nd candle.
Of course the analogy is really about CO2. So lets pick say … 1945 as the supposed appearance of the 2nd candle (CO2).
Why 1945? That is when CO2 really took off. Here is the CDIAC data in million metric tons of CO2.
And here is the data graphed. 1900 to 1945 in red. And 1945 to 2014 in blue. With trends. I used Woodfortrees for the graph and here is the url.
So … what are the trends.
1900 to 1945 = 0.0110866C / Year
1945 to 2014 = 0.00954579 / Year
I conclude the 2nd candle actually changed the trend downward by 0.00154081C / Year.
Maybe it wasn’t a candle? Maybe it was an ice cube.
I think only conspiracy theorists could come up with a 2nd candle theory when the trend actually went down.
Haven’t the “deniers” been saying this for a long time? Biofuels are a cruel joke on the poor. Driving up food prices and creating more CO2.
“The United Nations will officially warn that growing crops to make “green” biofuel harms the environment and drives up food prices, The Telegraph can disclose.
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).”
Billions squandered by idiots.
The preliminary reports about CO2 in 2013 are coming out. China wins! China is now so far out in front that no country will ever catch them.
China has quadrupled CO2 output since 1990, while the USA output is now back to 1990 levels.
It discredits the CO2 theory of global warming doesn’t it?
Did You Know Some Natural Gas Wells are 90% CO2? The IPCC and AGW try and tell us natural sources of CO2 (such as from volcanoes) are so small.
How hard do you think they are trying to detect large underground/undersea CO2 sources? Not very hard.
9 million cubic feet a day flow from that well, and 90% was CO2.
40 Years of Rising CO2 … 1940 to 1979. Officially CO2 measurements only started in the 50s, but I think one can extrapolate backwards.
CO2 didn’t have much effect. The Temperature trend over those 40 years was -0.026C per decade. About -0.1C for the 40 years.
Lets take a look at the same graph without the CO2 part.
While CO2 has increased by 85 ppm from when measurements began in 1958 and are estimated to have risen by 120 ppm since 1750, we should also realize that increases of 80 ppm to 100 pm occurred during the last 3 glaciations without humans burning fossil fuels.
” Air trapped in bubbles in polar ice cores constitutes an archive for the reconstruction of the global carbon cycle and the relation between greenhouse gases and climate in the past. High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations. Despite strongly decreasing temperatures, high carbon dioxide concentrations can be sustained for thousands of years during glaciations; the size of this phase lag is probably connected to the duration of the preceding warm period, which controls the change in land ice coverage and the buildup of the terrestrial biosphere.”
HADCRUT4 1930 to 1949 by Month.
Normally you see this part of the graph with 2 or 3 red ticks because it is done annually.
Keep in mind the highest red tick is an anomaly of 0.355C for August 1945. The anomaly for August 2012 was 0.532C. Which is only 0.177C warmer. (Corrected)

“Far from being “carbon neutral,” wood-burning biomass actually emits more carbon dioxide (the primary global warming greenhouse gas) per unit of energy produced than either gas or coal. Yes, trees can grow back and reabsorb that carbon, but that growth takes many years. The most recent studies show that
The renewability of wood is also questionable, as forests would be threatened by any meaningful increase in electricity generation using biomass as fuel. Replacing just 10 percent of the coal used in Pennsylvania would require more than 12.8 million green tons of wood per year — far more than the state’s annual commercial wood harvest (about 5 million tons).“
Read more here.
The new trendy fuel being proposed to replace the EPA/Hansen vilified coal is wood and/or biomass.
One biomass power plant “will emit 1,732 tons per day of carbon dioxide to produce 380,000 MWh of power annually, an emission rate of 3,327 lbs of CO2/MWh. For comparison carbon dioxide emission rates are 2,117 lbs/MWh for existing coal plants, 1,314 lbs/MWh for existing gas plants
and 760 lbs/MWh for new power plants.”
Lets put that in a table.
||lbs of CO2/Megawatt Hour
|Older Natural Gas
|New Natural Gas
“wood fueled biomass power plants emit about 50% more CO2 per MWh than existing coal plants, 150% more than existing natural gas plants and 330% more than new gas power plants.”
Thats right. Biomass/Wood produce 330% more CO2 than a new super-efficient natural gas power plant burning natural gas. And thanks to fracking the gas is super-cheap.
If you believe in the “CO2 will end the world scam”, then please fight hard against wood and biomass power plants. And fight hard for new natural gas power plants.
If you don’t believe, then laugh at the idiots who do. And tell them the truth.
If you are against fracking, and for biomass/wood power planets, you hate the planet.
