Global Warming May Have Been Caused By Deforestation

Yesterday I wrote about trees being able to seed clouds. Lubos of the Reference Frame takes it further.

It’s been generally thought that the sulfuric acid was almost necessary. Chimneys (or volcano eruptions etc.) should increase cloudiness. However, there have been inconclusive hints in some papers that some organic molecules are enough. You may have worried: How could have the clouds existed in the past, before the chimneys were built?😉

Jasper Kirkby and collaborators have found out that the molecules known as “aroma of the trees” may indeed do the same job and that is decisive in the pristine environments without chimneys.

More precisely, the molecules that can do the job are the “highly oxygenated molecules” (HOMs) which are produced by ozonolysis of α-pinene.

The lesson for “global warming” seems clear: deforestation may decrease the amount of aroma from the trees, and therefore the amount of clouds, and it may therefore lead to global warming.

This may be the explanation of the changes in the 20th century and because the deforestation is over, so may be “global warming”.


So … what other periods of global warming took place?

“The Roman Warm Period or the Roman climatic optimum has been proposed as a period of unusually warm weather in Europe and the North Atlantic that ran from approximately 250 BC to 400 AD”

What is Rome famous for (other than killing and conquering and so on)? Roman baths. What did the heat the baths with? Firewood.

“The baths were BIG; the Baths of Caracalla, completed in 235, could handle 8,000 visitors a day. Its 50 furnaces burned ten tons of wood every day to keep the water warm.

Deforestation was huge in Roman times.

Wood was a primary source of heating and used extensively in industry. Wood fuel constituted about 90 percent of the consumption overall,[citation needed] and was a major factor in Roman deforestation. Wood was essential fuel in industries like mining, smelting, and the making of ceramics.[4] Wood and charcoal were the primary ancient fuels in public facilities, households, public baths and industries that produced light and heat.

Forest areas around mining centers were deforested first, consuming all natural resources around the area of work. Once all the natural resources around the area of production were consumed, wood was then shipped and carried in to supply the furnaces and smelters for the mining centers. Eventually, these centers would shut down and move to areas within Roman territory to repeat the same cycle of deforestation, supplying an ever-growing population and consumption demand.

Deforestation and the fall of Rome :

In the ancient world, fossil fuels were unusual enough to be a curiosity, and certainly did not provide any major heating source. Almost all heating was done by wood and wood products1and while it may not seem like such a major factor it becomes a different story if you think about the Roman baths. The public baths2 were kept constantly at a minimum of 130 degrees Fahrenheit (54 degrees Celsius), and even a very small bath required 228,000lb (103,421kg) of wood per year. The Emperors recognised the importance of the baths in keeping the populace happy, and made keeping them running a primary goal. A whole guild, equipped with 60 ships, was created specifically for the purpose of obtaining bath-heating wood. Large palaces and villas also often had personal central heating systems; one such system has been evaluated and determined to require 2,506,000lb (1,136,722kg) of wood per year in order to properly heat the villa.

Trees Can Seed Clouds!

This discovery is huge. Trees can seed clouds.

Molecules released by trees can seed clouds, two experiments have revealed. The findings, published on 25 May in Nature1, 2 and Science3, run contrary to an assumption that the pollutant sulphuric acid is required for a certain type of cloud formation — and suggest that climate predictions may have underestimated the role that clouds had in shaping the pre-industrial climate.

If the results of the experiments hold up, predictions of future climate change should take them into account, says Reto Knutti, a climate modeller at the Swiss Federal Institute of Technology (ETH Zurich). For 20 or more years, clouds have been the largest source of uncertainty in understanding how manmade emissions affect the atmosphere, he says.

In addition to releasing carbon dioxide, burning fossil fuels indirectly produces sulphuric acid, which is known to seed clouds. So, climate scientists have assumed that since pre-industrial times, there has been a large increase in cloud cover, which is thought to have an overall cooling effect by reflecting sunlight back into space. And they have assumed that this overall cooling effect has partially masked the climate’s underlying sensitivity to rising carbon dioxide levels. The latest experiments suggest that it may have been cloudier in pre-industrial times than previously thought.

If this is so, then the masking effect, and in turn the warming effects of carbon dioxide, might have been overestimated, says Jasper Kirkby, a physicist at the CERN, Europe’s particle-physics laboratory near Geneva, Switzerland, who led one of the experiments.

Green Plans to Burn Wood in Alberta Instead of Coal

The green lobbyists have big plans for some of the coal power plants Rachel Notley and the NDP plant to close down.

The are going to convert them to burn trees. And quadruple the price of electricity.

There is more than enough fibre both in Alberta and Canada to fuel a major expansion in pellet production to feed one or two large Alberta coal-fired plants without much of an impact in overall fibre availability. Presenter Jamie Stephen of Torchlight Bioresources estimates a gap between AAC and actual harvest of over 39 million bone dry tonnes (BDT) across Canada, as well as the availability of residues topping 30 million BDT.

AAC is Annual Allowable Cut.

The technology and processes are proven and expertise widely available to convert coal-fired plants to biomass. Presentations by Bill Strauss of FutureMetrics, Brent Boyko of OPG and Brian Moran of U.K. bioenergy giant Drax made that abundantly clear.

Burning trees instead of coal is the future because government lobbyists can make people do stupid things.

The execution gap is economic, something outlined with some precision all day, but driven home by Mark Mackay of Transalta, Corp. Transalta is one of the three major power generators in Alberta with coal fired assets on hand. “If we say the current power market in Alberta is paying roughly $22/Mwh, and biomass is looking like $85/Mwh, somehow we have to think that equation through. I think government policy will be a big part of getting this started.”

More lobbying to take an abundant resource (coal) and replace it with forests and charge consumers 4 times as much.

The bulk of available biomass in Alberta and neighbouring B.C. is controlled by the major forest tenure holders, and so any solution will have to include them. Several speakers and attendees suggest the provinces could adopt a ‘use it or lose it” approach like Ontario.

Burn trees or else.

The next step is to build off the momentum created by this gathering of varied interests in Edmonton. In the closing chat, both WPAC executive director Gord Murray and Transalta’s Mark Mackay agreed that parties should work together to get this viable peak option in front of policy makers in Alberta. “It’s clear to me from this meeting that biomass is an option worth looking into, and that the will is there in this group to make it work,” Mackay concluded. “But time is of the essence. We have to get in front of government with this, and soon.”

Lobby politicians with huge amounts of money and be quick about it! Or those idiots building windmills will get all the government subsidies.

Climate “Scientists” off by a factor of 5.

Another study proving the science isn’t settled and the previous assumptions about catastrophic climate change just aren’t true.

Until now, most scientists have thought that a warming planet would cause plants to release more carbon dioxide into the atmosphere, which in turn would cause more warming.

But in a study published Wednesday in Nature, scientists showed that plants were able to adapt their respiration to increases in temperature over long periods of time, releasing only 5 percent more carbon dioxide than they did under normal conditions. Based on measurements of short-term temperature responses in this study and others, the scientists expected that the plants would increase their respiration by nearly five times that much.


Save The Coal: High-Grade Wood Going Up In ‘Biomass’ Smoke

The green plan to destroy forests by burning them in power plants is moving forward. Luckily, all that coal is being saved from being turned into electricity by the brave Biomass Plant Operators.

“Business owners in Cape Breton who rely on the forest for a living say high-quality hardwoods are making their way into Nova Scotia Power’s biomass plant in Point Tupper, consuming a wood supply that instead should be available for value-added businesses such as flooring and lumber.

David Fraser of BA Fraser Lumber in Margaree Valley, Inverness County, says he is seeing fewer quality saw logs and he blames it on Nova Scotia Power’s policy of getting the most amount of biomass fuel for the cheapest price.

Fraser, who runs a sawmill and is also a contractor who supplies wood to customers, said contractors simply can’t afford to separate quality saw logs from lower-quality stands of wood intended for the biomass plant.”

The plant requires 650,000 tonnes of trees per year for the $200 million power plant that only produces 60 Megawatts of power. Nova Scotia is closing coal power plants so they can burn trees instead.

Save The Endangered Coal! Trees are evil and must be burned instead.


Slaughtering Old Trees in Germany to Burn Coal And Close Down Nukes

In order to ensure the lights don’t go out after Germany’s latest stupid energy decision to shut down its nuclear power plants, they are slaughtering 12,000 year old Oaks to dig up up the dirtiest coal – Brown Coal.

Critics of the German government’s energy policy say it is unacceptable to raise C02 emissions by relying on coal as the country moves to switch off all its nuclear power plants by 2022. In order to extract the brown coal from the ground this winter, RWE will cut down 3,900 hectares of the 12,000-year-old oak and hornbeam Hambach forest, leaving just 300 hectares in tact.
