Global warming conspiracy theory is a collection of allegations that, through worldwide acts of professional and criminal misconduct, the science behind anthropogenic global warming has been invented and is being perpetuated for financial or ideological reasons. With all of the hysteria, all of the fear, all of the phony science, could it be that man-made global warming is the greatest hoax ever perpetrated on the American people,Global warming activists are as misguided as they are alarmist

Coming Picture Of A Supermassive Black Hole Will Be The 'Image Of The Century'?
Scientists have long suspected that supermassive black holes (SMBH) reside at the center of every large galaxy in our universe.
These can be billions of times more massive than our sun, and are so powerful that activity at their boundaries can ripple throughout their host galaxies.
In the case of the Milky Way galaxy, this SMBH is believed to correspond with the location of a complex radio source known as Sagittarius A*.
Like all black holes, no one has even been able to confirm that they exist, simply because no one has ever been able to observe one.
But thanks to researchers working out of MIT's Haystack Observatory, that may be about to change. Using a new telescope array known as the "Event Horizon Telescope"; (EHT), the MIT team hopes to produce this "image of the century" very soon.
Initially predicted by Einstein, scientists have been forced to study black holes by observing their apparent effect on space and matter in their vicinity. These include stellar bodies that have periodically disappeared into dark regions, never to be heard from again.
As Sheperd Doeleman, assistant director of the Haystack Observatory at Massachusetts Institute of Technology (MIT), said of black holes: "It's an exit door from our universe. You walk through that door, you're not coming back."
As the most extreme object predict by Einstein's theory of gravity, supermassive black holes are the places in space where, according to Doeleman, "gravity completely goes haywire and crushes an enormous mass into an incredibly close space."
To create the EHT array, the scientists linked together radio dishes in Hawaii, Arizona, and California. The combined power of the EHT means that it can see details 2,000 times finer than what's visible to the Hubble Space Telescope.
These radio dishes were then trained on M87, a galaxy some 50 million light years from the Milky Way in the Virgo Cluster, and Sagittarius A* to study the event horizons at their cores.
Other instruments have been able to observe and measure the effects of a black hole on stars, planets, and light. But so far, no one has ever actually seen the Milky Way's Supermassive black hole.
According to David Rabanus, instruments manager for ALMA: "There is no telescope available which can resolve such a small radius," he said. "It's a very high-mass black hole, but that mass is concentrated in a very, very small region."
Doeleman's research focuses on studying super massive black holes with sufficient resolution to directly observe the event horizon. To do this his group assembles global networks of telescopes that observe at mm wavelengths to create an Earth-size virtual telescope using the technique of Very Long Baseline Interferometry (VLBI).
"We target SgrA*, the 4 million solar mass black hole at the center of the Milky Way, and M87, a giant elliptical galaxy," says Doeleman. "Both of these objects present to us the largest apparent event horizons in the Universe, and both can be resolved by (sub)mm VLBI arrays." he added. "We call this project The Event Horizon Telescope (EHT)."
Ultimately, the EHT project is a world-wide collaboration that combines the resolving power of numerous antennas from a global network of radio telescopes to capture the first image ever of the most exotic object in our Universe – the event horizon of a black hole.
"In essence, we are making a virtual telescope with a mirror that is as big as the Earth," said Doeleman who is the principal investigator of the Event Horizon Telescope. "Each radio telescope we use can be thought of as a small silvered portion of a large mirror. With enough such silvered spots, one can start to make an image."
"The Event Horizon Telescope is the first to resolve spatial scales comparable to the size of the event horizon of a black hole," said University of California, Berkeley astronomer Jason Dexter. "I don't think it's crazy to think we might get an image in the next five years."
First postulated by Albert Einstein's Theory of General Relativity, the existence of black holes has since been supported by decades' worth of observations, measurements, and experiments. But never has it been possible to directly observe and image one of these maelstroms, whose sheer gravitational power twists and mangle the very fabric of space and time.
Finally being able to observe one will not only be a major scientific breakthrough, but could very well provide the most impressive imagery ever captured.
Carbon Capture and Storage (CCS) – the miracle technology which
will supposedly allow us to burn more coal while saving the planet from
global warming – is a complete waste of time and energy.
It’s so expensive that it makes even renewables and nuclear look cheap.
These findings – from a report
by Professor Gordon Hughes, Professor of Economics at the University of
Edinburgh and a former adviser to the World Bank – vindicate a recent
call by President Trump to cut the 2018 budget for CCS research by 77
They also make a mockery of the grandiose schemes proposed by the
International Energy Agency and the Intergovernmental Panel on Climate
Change to decarbonize the global economy in line with the Paris
Agreement. Both organizations have made heroic assumptions about the
value of CCS technology in helping to meet their CO2 reductions targets.
Here, for example, is the ex-head of the IPCC Rajendra Pachauri touting it at the time of the last IPCC Assessment Report in 2…
The Associated Press reports: SYDNEY — The ruling Labor Party's probable collapse in Australia's next election is largely the consequence of its qualified success in the last one three years ago. To form the coalition she needed to stay in power, then-Prime Minister Julia Gillard reneged on a promise and agreed to place a carbon tax on major polluters.
On Saturday, the bill for that bargain comes due. Voters have never stopped hating the tax and its effect on their electric bills. Longtime Labor Party supporters — even people who have helped cut pollution by installing solar panels at home — have flocked to the opposition.
"Whoever gets rid of it will get my vote," said Mark Keene, a 54-year-old maintenance worker from Sydney who, for the first time in his life, won't be voting for Labor.
Opposition leader Tony Abbott has declared the election a "referendum on the carbon tax" — a sure sign of confidence that most voters remain staunchly against it, with…
Hurricane Jose is still churning several hundred miles away in the
Atlantic Ocean, but already reports indicate that the fifth named storm
of the 2017 hurricane season will have negative impact on the east coast
of the United States.
What you need to knowDespite being a Category 4 hurricane at the height of its intensity, Jose has weakened to a Category 1.Weather Underground meteorologist Jeff Masters has reported
that it’s unlikely that Jose will make a U.S. landfall, as most
computer models indicate that the hurricane will continue to travel in a
tight loop and remain hundreds of miles away.If the hurricane continues its odd, spiraled path, impacts along the east coast could include rip currents, beach erosion and rough surf, according to AccuWeather.
What you can doHave a plan. Regardless of whether or not Jose
impacts the east coast, a plan for inclement weather should always be in
place and be ready to go at a moment’s notice.
Keep aware of the risks that might be posed …
