Once the data starts coming in from this satellite, among the others already up and measuring, the question of whether humans are the major cause of CO2 rise in the atmosphere will be settled once and for all. Even the folks on this thread will be hard pressed to deny the undeniable, if humans are indeed the cause. What I find so ludicrous is that folks on this thread and others I've talked to so dramatically underestimate how powerful our scientific methods are today. If they really knew what tools scientists are using today, they'd trust science a lot more and lobbyists a lot less. I'm really looking forward to the Obama administration where science and technology will once again reign. I hear he's already appointed Steve Chu, the first real scientist in the last 11 appointments, for Energy Secretary. This is a nobel prize winner and active research scientist. I love it when our politicians appoint competent people instead of trying to play politics. He's off to a good start. This country needs to get back to intellectualism and technology, so we can start creating wealth again. From the article:The observatory will be engaged in what amounts to carbon accountancy. Its fortnightly global maps of CO2 concentration will help the mission team work out where the gas is entering the atmosphere and where it is being absorbed by land plants and the oceans. OCO weighs just under half a tonne Scientists have calculated that nature cycles about 330 billion tonnes of carbon every year. Human activities put about 7.5 billion tonnes into the atmosphere - a tiny sum in comparison but enough, say researchers, to imbalance the system and raise the global mean surface temperature of Earth. 1. OCO will head the 'train' of satellites when it gets into orbit. It will measure the concentration of carbon dioxide in the lower atmosphere 2. Aqua will lag OCO by 15 minutes. It is collecting information about the Earth's water cycle - water in the oceans, the air and on the land 3. Cloudsat will allow for the most detailed study of clouds to date. It should better characterise their role in regulating the climate 4. Calipso views clouds just moments after Cloudsat has looked at them. Its primary interest is the way aerosols interact with clouds 5. Parasol is a French satellite that can distinguish natural from human-produced aerosols. It makes polarised light measurements 6. Glory will join the train in June. One task will be to measure the 'energy budget' of Earth, to determine accurately global temperature 7. Aura also has a big European investment. It looks at atmospheric chemistry, and is producing remarkable global pollution maps news.bbc.co.uk
