Take a read here.

Global Warming Alarmists Caught Doctoring '97-Percent Consensus' Claims - Forbes
It attacks a paper about the evolution of trends in consensus amongst climate scientists. At one point they say "most skeptics as well as most alarmists believe humans have caused some global warming", which I thought was interesting. The paper in question says:

"We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991–2011 matching the topics 'global climate change' or 'global warming'. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming."

So they are saying that 97.1% of 33.6% (in other words, 32.6%) of nearly 12000 abstracts are prepared to blame humans for it. We can set these 3893 against the 84 rejecting human involvement, 7931 abstracts expressing no particular view, and 36 don't knows. Apparently some of the "supporters" don't like that label, but even if they are switched to the "anti" side, there is still a strong scientific consensus in support of an anthropogenic component to climate change.

Maybe all 3893 abstracts are wrong: it's possible. But not very likely, without invoking vague conspiracy theories and arguments from personal incredulity.

Im also a professional scientist, but a geologist. My viewpoint is based purely on knowledge of earth processes and the history of the planet. I have no doubt our climate is changing - I'm just not convinced human activity has that great an impact.

The global warming phenomenon is based on measurements since about the 1850's - an infinitesimal sampling of our planets history - but it is a well established scientific observation, that our planet has gone through several periods of alternate heating and cooling, and will continue to do so. We just happen to be at the peak of a warm cycle.

The earth is about 4.5 billion years old - 160 odd years of temperature measurement is an insignificant period on which to make observations and then make predictions. The climate always has changed, and always will - fact. There is nothing humankind can do about it.

This is the argument from personal incredulity ("I'm just not convinced") coupled with dogmatic assertion ("There is nothing humankind can do about it"). Has the entire Intergovernmental Panel failed to spot what you consider pretty obvious? They say "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century." You say we've got nothing to do with it. Well, maybe all of the IPCC scientists are wrong. It's possible.

Seems reasonable.

Jupiter's Great Red Spot Shrinks to Smallest Size Ever Seen

Quote:
Jupiter's Great Red Spot — the most powerful storm in the solar system — is at its smallest observed size yet, and scientists aren't sure why.
Recent Hubble Space Telescope images of the storm show that it is now 10,250 miles (16,496 kilometers) across, which is less than half the size of the storm in the late 1800s. At one point, scientists theorized that three Earths could fit inside the Great Red Spot, but today, only the width of one Earth could fit within the raging tempest. You can watch a Great Red Spot video for more views of the diminishing storm.

Hubble astronomers, including Simon, will take part in a webcast about Jupiter's shrinking Great Red Spot on May 22 at 4 p.m. EDT

Finally the weather cooperated and I saw the ISS on this pass:

I may have seen another satellite too. When ISS was nearly at about 80° elevation another object traveling at 90° to ISS appeared and disappeared. Total time visible was 3 seconds or so. No clouds at all so it was obscured.

That was Brink...he has a hot date on NGC 253 this evening.

I have it marked on the calendar Steve, thanks for the reminder.

I thought this idea was pretty funny. Probably one of the very few 4chan memes worth porting over to SevenForums, as it isn't TOTALLY stupid (also doesn't contain offensive images).
