this kind of thing is interesting: http://news.nationalgeographic.com/news/2007/02/070228-mars-warming.html
Ice on Mars began melting AFTER we started sending man-made vehicles to traverse its surface. Got to be a connection there somewhere.
Most of the world has only been keeping temperatures for 50 years. There are many places in africa, canada, and the middle east that have been only recording temperatures for less than 10 years. So to say that this is the warmest decade in the last 5 decades is not something big. We had a 20% chance of it being the warmest decade, just out of chance. This decade we have a 16.6% chance of it being the warmest decade again, then a 14.2% chance next decade. If it gets cooler this decade then what? Will we stop with the global warming bullcrap?
I am pretty stoked. 15 more years of warming. I feel sorry my kids will have to suffer through steep cooling right about the time they will be enjoying the beach. "The solar irradiance began to drop in the 1990s, and a minimum will be reached by approximately 2040," Abdussamatov said. "It will cause a steep cooling of the climate on Earth in 15 to 20 years."
"Global Warming âGlobal warmingâ refers to the global-average temperature increase that has been observed over the last one hundred years or more. But to many politicians and the public, the term carries the implication that mankind is responsible for that warming. This website describes evidence from my groupâs government-funded research that suggests global warming is mostly natural, and that the climate system is quite insensitive to humanityâs greenhouse gas emissions and aerosol pollution. Believe it or not, very little research has ever been funded to search for natural mechanisms of warmingâ¦it has simply been assumed that global warming is manmade. This assumption is rather easy for scientists since we do not have enough accurate global data for a long enough period of time to see whether there are natural warming mechanisms at work. The United Nationâs Intergovernmental Panel on Climate Change (IPCC) claims that the only way they can get their computerized climate models to produce the observed warming is with anthropogenic (human-caused) pollution. But theyâre not going to find something if they donât search for it. More than one scientist has asked me, âWhat else COULD it be?â Well, the answer to that takes a little digging⦠and as I show, one doesnât have to dig very far. But first letâs examine the basics of why so many scientists think global warming is manmade. Earthâs atmosphere contains natural greenhouse gases (mostly water vapor, carbon dioxide, and methane) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation â the radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankindâs burning of fossil fuels (mostly coal, petroleum, and natural gas) releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earthâs natural greenhouse effect. As of 2008, the concentration of carbon dioxide in the atmosphere was about 40% to 45% higher than it was before the start of the industrial revolution in the 1800âs. It is interesting to note that, even though carbon dioxide is necessary for life on Earth to exist, there is precious little of it in Earthâs atmosphere. As of 2008, only 39 out of every 100,000 molecules of air were CO2, and it will take mankindâs CO2 emissions 5 more years to increase that number by 1, to 40. The âHoly Grailâ: Climate Sensitivity Figuring out how much past warming is due to mankind, and how much more we can expect in the future, depends upon something called âclimate sensitivityâ. This is the temperature response of the Earth to a given amount of âradiative forcingâ, of which there are two kinds: a change in either the amount of sunlight absorbed by the Earth, or in the infrared energy the Earth emits to outer space. The âconsensusâ of opinion is that the Earthâs climate sensitivity is quite high, and so warming of about 0.25 deg. C to 0.5 deg. C (about 0.5 deg. F to 0.9 deg. F) every 10 years can be expected for as long as mankind continues to use fossil fuels as our primary source of energy. NASAâs James Hansen claims that climate sensitivity is very high, and that we have already put too much extra CO2 in the atmosphere. Presumably this is why he and Al Gore are campaigning for a moratorium on the construction of any more coal-fired power plants in the U.S. You would think that weâd know the Earthâs âclimate sensitivityâ by now, but it has been surprisingly difficult to determine. How atmospheric processes like clouds and precipitation systems respond to warming is critical, as they are either amplifying the warming, or reducing it. This website currently concentrates on the response of clouds to warming, an issue which I am now convinced the scientific community has totally misinterpreted when they have measured natural, year-to-year fluctuations in the climate system. As a result of that confusion, they have the mistaken belief that climate sensitivity is high, when in fact the satellite evidence suggests climate sensitivity is low. The case for natural climate change I also present an analysis of the Pacific Decadal Oscillation which shows that most climate change might well be the result ofâ¦.the climate system itself! Because small, chaotic fluctuations in atmospheric and oceanic circulation systems can cause small changes in global average cloudiness, this is all that is necessary to cause climate change. You donât need the sun, or any other âexternalâ influence (although these are also possibleâ¦but for now Iâll let others work on that). It is simply what the climate system does. This is actually quite easy for meteorologists to believe, since we understand how complex weather processes are. Your local TV meteorologist is probably a closet âskepticâ regarding mankindâs influence on climate. Climate change â it happens, with or without our help." http://www.drroyspencer.com/global-warming-natural-or-manmade/
