President Obama has promised that 600,000 jobs will be saved, yet we have been losing 500,000 + jobs every month for several months.
The current administration is only creating cheap labour. They want for Americans to do MANDATORY Community Service WITHOUT PAY = SLAVERY...

How much revenue is created by fossil fuels? The government will never let go of that, they just added another tax on top of it.
Shortsightedness indeed, tell it to the people who are going to freeze to death next winter, or tell it to the people that'll start starving to death because they can't afford to eat.

No I just don't like fat cats (like AL Gore) pushing new taxes and restrictions on us to "save the planet" while they themselves spew tons of CO2 with their private airplanes and huge mansions.
I am all for renewable energy but the technology has to work.

Abstract
We reconstruct environmental conditions of coastal Northwestern Florida from combined measurements of δ18O and Sr/Ca of fossil marine bivalves deposited in an archeological site during the late Holocene period. We first investigated the environmental controls of seasonally resolved records of δ18O and Sr/Ca of modern Mercenaria mercenaria and Mercenaria campesiensis collected live from five coastal sites along the east coast of North America. Seasonal profiles were obtained by sub-sampling the incremental growth layers of aragonite and were compared with in situ historical records of temperature and salinity. We show that these bivalves precipitate their shell in isotopic equilibrium with the water in which they grew and that the δ18O records are not affected by variations in growth rate. Winter growth appears to be interrupted or strongly reduced below water temperatures ranging from 7 to 18° C, depending on latitude. The annual average δ18O decreases with latitude, reflecting both the parallel trend of freshwater δ18O with latitude over the North American continent and the reduced winter growth rate. The Sr/Ca records of the 5 modern bivalves also exhibit seasonal variations can be correlated to water temperature. However, contrary to corals, the Sr/Ca ratio is considerably lower than the average sea water Sr/Ca composition and is positively correlated to the water temperature. We dated and measured the δ18O and Sr/Ca of 30 fossil M. campesiensis from an archeological site close to Cedar Key, in the Gulf of Mexico. Accelerator Mass Spectrometry 14C dates obtained for each shell show ages which cluster between 1100 to 1400 and 2300 to 2600 14C years BP corresponding approximately to two historical warm periods known as the Medieval Warm Period (~ 1300-900AD) and the Roman Warm Period (~ 250AD-200BC). The average annual and summer Sr/Ca of 4 fossil shells are higher than that of modern bivalves from the same location suggesting that annual coastal water temperatures were 3 to 4° C warmer than today. The bulk δ18O values show a marked trend towards more positive values. 24 fossil shells have bulk δ18O values 0.2\permil to 0.7\permil more positive than modern bivalves from the same location. These results suggest that the coastal waters off northwest Florida were warmer and less saline compared to today and attest of considerable differences of the regional climate and hydrological balance during the Medieval Warm Period and Roman Warm Period.
Current warmth seems to be occurring nearly everywhere at the same time and is largest at high latitudes in the Northern Hemisphere. Over the last 50 years, the largest annual and seasonal warmings have occurred in Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Because these areas are remote and far away from major cities, it is clear to climatologists that the warming is not due to the influence of pollution from urban areas.

Galactic energy and its role in a changing Earth
--------------------------------------------------------------------------------
ALAN P.M. VAUGHAN
Proposed climate change mechanisms are many and various but generally attributable to our part of the solar system. They usually focus on temperature changes driven either by local processes such as variations in oceanic circulation, or, levels of atmospheric greenhouse gases such as carbon dioxide, or by global processes such as variations in received solar energy linked to changes in the parameters of the Earth's rotation and orbit or solar activity. However, two recent papers have suggested that we may need to look outside the Earth System and even outside our local planetary system for the possible origins of climate change, both on a decadal scale and over longer timescales of hundreds of millions of years. In each case, the galactic cosmic ray flux and its potential effects on cloud formation is considered to be the culprit.

Abstract
Qinghai Lake is a large saline lake on the Qinghai–Tibetan Plateau of central Asia that is effected by both the Indian and Asian monsoons. We used reflectance spectroscopy to characterize the sediments in a 795-cm long core taken from the southeastern part of the lake. Sediment redness, which is related to iron oxide content, seems to monitor paleoclimatic changes in the core. Iron oxides appear to be eroded from nearby red beds or loess deposits and are transported by fluvial means into the lake. Thus, redness increases at times of increased precipitation, that is, as monsoon strength increases. Our redness monsoon proxy shows climate changes on several times scales. On a millennial scale, it records humid conditions during the Early and Mid-Holocene. From about 4200 to 2300 yr BP, low redness values suggest a two-millennial long dry period, which in the Late Holocene is followed by a more humid period. On a centennial scale, the redness proxy records not only the Little Ice Age, but also the Medieval Warm Period, the Dark Ages Cool Period and the Roman Warm Period. Time series analysis of the redness record indicates a 200 yr frequency, which corresponds to the de Vries solar cycle suggesting that, in addition to insolation changes resulting from orbital variations, solar forcing also results from cyclic changes in the suns luminosity.

I'm actually a Human Ecology major come the fall and I'm spent the past four years studying primarily the sciences. I've done tons of research, you can go look at some of my threads.
Honestly even if it's not Global Warming you can't deny that some climate change is happening because of us. Even just pollution and deforestation which has nothing to do with CO2.
We should be increasing taxes for this. We should get rid of our dependence on oil. No matter what, that has to happen.
You pay attention to the research you want to believe. So do I. But I'd rather be safe than sorry. And I'm a liberal, I don't trust businesses and people to begin with, and I'd rather trust the government to regulate all the greedy money makers in business and take my chances with the people in government.

Abstract
Evidence is presented that the recent worldwide land warming has occurred largely in response to a worldwide warming of the oceans rather than as a direct response to increasing greenhouse gases (GHGs) over land.
Atmospheric model simulations of the last half-century with prescribed observed ocean temperature changes, but without prescribed GHG changes, account for most of the land warming. The oceanic influence has occurred through hydrodynamic-radiative teleconnections, primarily by moistening and warming the air over land and increasing the downward longwave radiation at the surface. The oceans may themselves have warmed from a combination of natural and anthropogenic influences.
Thousand of new volcanoes revealed beneath the waves

The true extent to which the ocean bed is dotted with volcanoes has been revealed by researchers who have counted 201,055 underwater cones. This is over 10 times more than have been found before.
The team estimates that in total there could be about 3 million submarine volcanoes, 39,000 of which rise more than 1000 metres over the sea bed.
"The distribution of underwater volcanoes tells us something about what is happening in the centre of the Earth," says John Hillier of the University of Cambridge in the UK. That is because they give information about the flows of hot rock in the mantle beneath. "But the problem is that we cannot see through the water to count them," he says.
Satellites can detect volcanoes that are more than 1500 m high because the mass of the submerged mountains causes gravity to pull the water in around them. This creates domes on the ocean's surface that can be several metres high and can be detected from space.

Abstract
During the past 6000 years, the temperature variation trend inferred from δ18O of peat cellulose in a peat core from Hongyuan (eastern Qinghai–Tibet plateau, southwestern China) is similar to the atmospheric 14C concentration trend and the modeled solar output trend. The general trend of Hongyuan δ18O during the past millennium also coincides well with the atmospheric 14C concentration trend, the 10Be concentration trend in an ice core from the South Pole, the reconstructed total solar irradiance trend, as well as the modeled solar output trend. In addition, temperature events also correspond well to solar perturbations during the past 6000 years. Therefore, the driving force of Holocene temperature variations should be properly ascribed to solar activity. The spectrum analysis further illustrates that quasi-100-yr fluctuation of solar activity was probably responsible for temperature variations in northeast Qinghai–Tibet plateau during the past 6000 years.
