After two years in orbit, the European Space Agency’s (ESA) Gravity field and steady-state Ocean Circulation Explorer (GOCE) is nearing the end of its planned life span in February, producing the most accurate map ever of the so-called geoid -- an Earth-encompassing spirit level and global reference surface.
Markedly different from a simple sphere or ellipsoid, the geoid is the mathematically 'true' shape of Earth. It represents a motionless global ocean but takes into account the effects of the Earth’s rotation, weight difference resulting from the position of mountains and ocean trenches, and uneven mass distribution and density variations in the planet’s interior.
The resulting small variations in the Earth’s gravitational field feature on the geoid as ‘bulbs’ and ‘dips’ in an idealized ‘ocean’ surface.
ESA scientists presented the latest version of the GOCE-derived geoid map –- based on eight months of data processed so far –- at a user workshop this week in Munich, Germany.

"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther

How can, the suface temp. decrease when the "greenhouse gases" increase?
What happen in the 1960's to cause such an increase? all the flag burning? roits?
The controversy is significantly more pronounced in the popular media than in the scientific literature,[1][2] where there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view,[3][4]
As you admit "In science, no nothing is for absolute sure" Next they'll be blaming farts for global warming, o they have already. And that humans are the cause of CO2 pollution. O they have already, EVERYBODY STOP BREATHING!
So, tomorrow, they find out that it's the oceans, or birds, or whales, or a passing rock, or... or... or... that cause global warming? And then they'll all say "Opps! we were wrong, sorry! Sorry for all the new regulations, taxes, & politics!", and of course the regulations, taxes, & politics will stay in place.
Skeptics often claim that the science of anthropogenic global warming (AGW) is not “settled”. But to the extent that this statement is true it is trivial, and to the extent that it is important it is false. No science is ever “settled”; science deals in probabilities, not certainties.
Some aspects of the science of AGW are known with near 100% certainty. The greenhouse effect itself is as established a phenomenon as any: it was discovered in the 1820s and the basic physics was essentially understood by the 1950s. There is no reasonable doubt that the global climate is warming. And there is also a clear trail of evidence leading to the conclusion that it’s caused by our greenhouse gas emissions. Some aspects are less certain; for example, the net effect of aerosol pollution is known to be negative, but the exact value needs to be better constrained.
How can so many be so wrong/or right at the same time?
How many scientists do you think disagree that AGW is occurring, and man-made, versus don't?
Plant a tree, they USE the EVIL CO2 to live and release O2. Wait if we get rid of the CO2, then all the trees will die, what a shame, O-well less fires that produce pollution.
Absolutely no one has said anything about getting rid of all the CO2. On the contrary, eliminating CO2 would take away a crucial mechanism of the earth to warm enough to support life. Snowball earth isn't desirable either. What many don't realize is that too much CO2 is detrimental for plants growth as well - their growth falls in a bell curve of a range to which they have evolved for optimized growth. Just like putting a plastic bag over your head and concentrating the CO2 would be very detrimental to your health, so too is too much CO2 for plants - the effects are just slower and less noticeable to those who don't take long-term metrics.

"The idea is that yawns are contagious for the same reason that smiles, frowns and other facial expressions are contagious," they write. "Our results support the idea that contagious yawning can be used as a measure of empathy, because the biases we observed were similar to empathy biases previously seen in humans."
The authors say that contagious yawning could be a window into social and emotional connections between individuals, and suggest that insight into barriers to chimpanzee empathy may help break down those barriers for humans.
"Empathy is difficult to measure directly because it is a largely internal response: mimicking the emotional response of another. Contagious yawning allows for a measurement of empathic response that is purely behavioral, and thus can be applied more widely," Campbell writes.
In 2007, a man from Woodbridge, Virginia was rushed into hospital after inhaling an aerosolised version of one of the deadliest poisons on the planet. He was not the victim of a terrorist attack. He wasn’t working in a biohazard laboratory. He was trying to clean out his fish tank.
The man, who posts on the Reef Central Forums as Steveoutlaw, was trying to get rid of a colony of zoanthids – a relative of corals and sea anemones – that was infesting his aquarium rocks. He had heard that boiling water would do the trick. When he tried it, he accidentally inhaled some of the steam. The reason for his sudden illness was palytoxin, a speciality of zoanthids, and the second deadliest poison in the natural world. One gram of the stuff will kill more than a hundred million mice.
Deeds was investigating a case of palytoxin poisoning when he heard about Steveoutlaw’s unfortunate incident. He visited the man, collected a sample of the offending zoanthid, and found that it was indeed heavy with palytoxin. It wasn’t hard to get his hands on more. Deeds bought 15 more colonies from three aquarium stores in the Washington DC area, of the same species that gave Steveoutlaw his whiff of toxic steam. Three of the samples yielded even more poison. Every gram contained enough palytoxin to kill 300,000 mice, or around 80 people.
PS Venom enthusiasts know that the potency of poisons is measured using the LD-50 – the dose that will kill half a group of mice after a set time. The most venomous snake has an LD-50 of 25 micrograms per kilogram of body weight. For tetrodotoxin, the equivalent figure is 8 micrograms. For batrachotoxin, the poison from the skin of poison dart frogs, it’s 2-7 micrograms. For palytoxin, it’s 0.3 micrograms (or 300 nanograms).

Researchers at Eindhoven University of Technology (TU/e, Netherlands) have developed an active electromagnetic suspension system that can increase the ride quality of cars by 60 percent. Cars fitted with this suspension system are also safer because they no longer roll (sway) in corners.
The aim is ultimately to develop more comfortable cars that also have higher safety. This is because the roadholding is improved and the car no longer rolls in bends. For example a car fitted with this suspension system will be much less likely to overturn as a result of abrupt steering maneuvers, such as the slaloming involved in the notorious ‘elk test’.
The system replaces the normal shock absorber in a car, and itself has approximately the same size as a shock absorber. It consists of a passive spring, a powerful electromagnetic actuator, a control unit and batteries. The system is designed to be inherently safe. Even if the electrical power fails, the springing and shock absorbers will continue to work. The passive spring in the system provides springing, and the magnets provide passive, magnetic shock absorption.

"In summary," the authors write, "we have demonstrated that light propagation delays present new opportunities for statistical arbitrage at the planetary scale, and have calculated a representative map of locations from which to coordinate such relativistic statistical arbitrage among the world’s major securities exchanges. We furthermore have shown that for chains of trading centers along geodesics, the propagation of tradable information is effectively slowed or stopped by such arbitrage."
OK, yes I read it, I could post a lot about folks that don't beleive in the "consensus" (I really don't like that word).
So, as I've said "Yes, Dear", not to agree, but to move on...

I don't want you to move on - I want to you consider the evidence with an open mind and find me more skeptical stuff!

Could messy streets lead to discrimination? A Dutch study finds they might.
During a cleaner's strike
at a train station in Utrecht, researchers found that when the environment was disordered and dirty, white Dutch people tended to sit further away from Dutch people of African descent. After the strike was over and the station was again neat and clean, they repeated the study and found that white Dutch people didn't seem to care about the race of the person in the seat near them.
Disorder increases the need for structure, the researchers posit. "Stereotyping is a way to cope with chaos, a mental cleaning device in the face of disorder," their paper, published in this week's edition of the journal Science, says.
