Where is the proof that the ONLY reason CO2 levels are rising now is because of us?
Although equally important today, the role of the terrestrial biosphere as a sink of anthropogenic CO2 emissions is still poorly understood.
Any prediction of future climate strongly relies on an accurate knowledge of the greenhouse gas concentrations in the present-day atmosphere, and of their development in the future.
Despite intensive research in the last decades, the uncertainty of the gross exchange rates between carbon reservoirs is still in the order of ±20%, and it remains difficult to univocally quantify the repartition of net uptake between the biosphere and the oceans, and thus, to predict the fate of anthropogenic CO2 emissions.
As mentioned earlier, it is important to know explicitly which fraction of the anthropogenic emissions enters the biosphere and which fraction enters the oceans, because carbon storage in these two reservoirs behaves very differently.
The carbon is ours and there are not really any other suspects for the cause of warming.

isn't the US doing as much or more than other nations? Until the others do their part, yelling at us won't change the dynamic. It sounds like folks like yourself would do better telling China all about the future woes. I'm looking forward to the beach being closer.

Abstract
....................
Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the near future and might have a drastic influence on terrestrial climate in the next 10,000 years.

Summary:
Is the Sun going to enter a million-degree galactic cloud of interstellar gas soon? A U.S.-Polish team of scientists suggests that the ribbon of enhanced emissions of energetic neutral atoms, discovered last year by the NASA Small Explorer satellite IBEX, could be explained by a geometric effect due to the approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble. If this hypothesis is correct, IBEX is catching matter from a hot neighboring interstellar cloud, which the Sun might enter in a hundred years.

In what is largely a reversal of an August announcement, astronomers today said Pluto is undergoing global warming in its thin atmosphere even as it moves farther from the Sun on its long, odd-shaped orbit.

However, this interest began to increase the connection between cosmic rays and sunspots, carbon-14 in the atmosphere, beryllium-10 on the surface of meteorites, and other processes. In particular, it was found that carbon-14 dating needed to be corrected for fluctuations in cosmic ray flux.

The red line is the C14 production rate, inverted. C14 production is inversely related to solar activity, so we see more C14 production during solar minima.

ExxonMobil climate change controversyThe ExxonMobil climate change controversy concerns ExxonMobil's activities related to global warming, especially their opposition to established climate science. Since the 1970s, ExxonMobil engaged in climate research, and later began lobbying, advertising, and grant making, some of which were conducted with the purpose of delaying widespread acceptance and action on global warming.
From the late 1970s and through the 1980s, Exxon funded internal and university collaborations, broadly in line with the developing public scientific approach. From the 1980s to mid 2000s, the company was a leader in climate change denial, opposing regulations to curtail global warming. ExxonMobil funded organizations critical of the Kyoto Protocol and sought to undermine public opinion about the scientific consensus that global warming is caused by the burning of fossil fuels. Exxon helped to found and lead the Global Climate Coalition of businesses opposed to the regulation of greenhouse gas emissions.

Mysterious Source of High-Energy Cosmic Radiation Discovered
WASHINGTON -- Scientists announced Wednesday the discovery of a previously unidentified nearby source of high-energy cosmic rays. The finding was made with a NASA-funded balloon-borne instrument high over Antarctica.
Researchers from the Advanced Thin Ionization Calorimeter (ATIC) collaboration, led by scientists at Louisiana State University, Baton Rouge, published the results in the Nov. 20 issue of the journal Nature. The new results show an unexpected surplus of cosmic ray electrons at very high energy -- 300-800 billion electron volts -- that must come from a previously unidentified source or from the annihilation of very exotic theoretical particles used to explain dark matter.
"This electron excess cannot be explained by the standard model of cosmic ray origin," said John P. Wefel, ATIC project principal investigator and a professor at Louisiana State. "There must be another source relatively near us that is producing these additional particles."

Space radiation hits record high
By David Shiga
Now, the influx of galactic cosmic rays into our solar system has reached a record high. Measurements by NASA's Advanced Composition Explorer (ACE) spacecraft indicate that cosmic rays are 19 per cent more abundant than any previous level seen since space flight began a half century ago."The space era has so far experienced a time of relatively low cosmic ray activity," says Richard Mewaldt of Caltech, who is a member of the ACE team. "We may now be returning to levels typical of past centuries."
