NEW NASA SURVEY FINDS ANTARCTICA COVERED IN MORE ICE THAN PREVIOUSLY THOUGHT
Trevor English, Interesting Engineering
Antartica is one of the most ice-covered locations in the world, but it is also one of the world’s largest land masses. Previous estimates by researchers placed the level of uncovered land in Antartica at about 1%. However, a new survey in part by NASA shows that this estimate was rather generous and the continent is covered in a lot more ice than previously thought. Researchers from Cryosphere have shown that only.18 percent of the entire continent is not covered by ice and snow, which is surprisingly low. With this new figure, researchers will monitor this survey over time to see the effects of climate change and global warming.

“With effects ranging from influencing ocean currents to raising sea level, Antarctica plays a large role in the global climate system. Researchers are using a variety of methods to understand how Antarctica will react to a changing climate, but limited information on ice thickness and what lies beneath the ice makes this work challenging.” ~ NASA
This new research has been put off for a while, and it may surprise you that this is the first time we have had an accurate representation of Antartica’s land mass. Automated techniques were used in the new study to allow seamless data collection as well as the automatic removal of clouds over the continent to make the snow and ice readings more accurate. The NASA and US Geological Survey satellite was used for the new study, which corrected previous ice and snow calculations in comparison to land mass.
In 2009: Warming would stop 2020 Olympics. Now disaster moved to 2084
In 2009: The 2016 Rio Games predicted be the last Global warming could make 2016 Games ‘the last Olympics in the history of mankind’, says Tokyo governor. “Global warming is getting worse. We have to come up with measures without which Olympic Games could not last long. “Scientists have said we have passed the point of no return,” said Ishihara. August 2016: The 2080 Games predicted to be the last Move that disaster by 60 years: “A sobering new study shows that by the 2084 Olympics, rising temperatures will make it practically impossible for most cities to host the summer games. How will the Olympics cope with a 1.5C rise? Answer, easily. Assuming the world warms, the IOC could shift games a whole 400km from Rio, where the average max is 28C in August to Sao Paulo where it’s 3 degrees cooler. Or they could shift the timing by all of eight weeks. If Moscow held the Olympics in September instead of July the event could survive an apocalyptic nine degree future rise. (Moscow in July has a 24C average max temperature, by September that has fallen to 15C average.) The government […]Rating: 10.0/10 (5 votes cast)

Obama: ‘Much more to do’ on climate changePresident Obama praised his administration on Saturday for the progress it has made combating climate change over the past seven-and-a-half years, but pressed Americans to step up their resolve to save the environment in his final six months in office.
“There’s still much more to do. But there’s no doubt that America has become a global leader in the fight against climate change,” Obama said in the weekly White House address. “And if we keep pushing, and leading the world in the right direction, there’s no doubt that, together, we can leave a better, cleaner, safer future for our children.”
The progressive president cited a number of domestic victories that have decreased Americans’ energy bills, including multiplying the availability of wind power threefold and solar power thirty-fold, lowering the price of clean power sources and bringing carbon pollution levels from the energy sector to its lowest level in 25 years.
While the auto industry has experienced record sales in recent years, that surge is not hurting the environment despite more vehicles on the road. The Obama administration has implemented new standards to ensure the distance cars and light trucks go on a gallon of gas increases every year through 2025.
But the changes Americans have seen unfolding all around them are only the beginning, Obama explained.
The White House plans to release a second round of fuel efficiency standards, but these will be for heavy-duty vehicles. In addition, the U.S. will move forward on its goal to achieve 50 percent clean power across North America by 2025 through partnerships with Canada and Mexico.
“Together, we must continue to work domestically and build upon the progress we’ve made along with other countries – such as the Paris Agreement, the most ambitious climate change agreement in history,” Obama said.
Obama readies final rule in climate agenda
The Obama administration is expected to issue the last rule in the president’s far-reaching climate change agenda as soon as Tuesday, setting new greenhouse gas and fuel efficiency standards for big-rig trucks.
That may be the reason the president used his Saturday radio address to underscore the new rules in discussing the steps he will be taking to combat global warming, which he called “one of the most urgent challenges of our time.”
“But we’re not done yet,” when it comes to taking action to reduce greenhouse gas emissions, he said. “In the weeks and months ahead, we’ll release a second round of fuel efficiency standards for heavy-duty vehicles,” as well as taking steps with Canada and Mexico to achieve a 50-percent clean energy goal for the continent by 2025.
Mexico is planning to issue its own rules for big trucks, and Obama has agreed to harmonize the forthcoming U.S. truck standards with Canada.

The final truck rule is phase two of the Environmental Protection Agency’s joint program with the Department of Transportation to cut greenhouse gas emissions from heavy-duty trucks beginning in 2019. Phase one of the joint climate and efficiency rules end for model-year 2018 vehicles.
The new regulations were proposed last year and after next week will become law to be implemented under the next president’s watch.
The truck rules establish standards to improve fuel efficiency and to reduce greenhouse gas emissions. Many scientists blame the emissions from burning fossil fuels for warming the Earth’s climate, resulting in more droughts and flooding.
Big-rig trucks account for almost 20 percent of the nation’s greenhouse gas emissions and oil consumption while only making up about 5 percent of all vehicles on the road.
The rules are expected to be issued next week with most of the large trucking fleets’ blessing. Yet, some in the industry are worried about added measures that will increase the stringency of the rules and make them more expensive to meet.

Cummins, the largest engine maker in the world for big trucks, is supporting the rules, despite reservations it is hearing from some, a senior official with the company told the Washington Examiner.
“We have worked …
Global Warming Extremists Try To Silence Science — Again
Climate Change: Global warming advocates like to pretend they are open-minded, all about science. But let someone else’s science get in the way of their “consensus,” and you find out how little they really believe in science.
Just ask Professor Valentina Zharkova of Britain’s Northumbria University. She and a team of researchers conducted a study on sunspots, which are known to have a strong effect on solar radiation and thus on the Earth’s climate.
What they found was remarkable: solar activity, based on models that closely fit past trends, looks to be headed for a sharp downward turn. Indeed, activity could decline to levels not seen since the so-called “Little Ice Age,” an unusually cold period that stretched across the Northern Hemisphere and lasted from roughly 1650 to 1850.
As such, a study of this kind, you might think, would be incredibly important. But instead of being greeted with scientific questions or open curiosity about her group’s study, Zharkova’s team was met with a most unscientific hostility.
“Some of them were welcoming and discussing,” she said in an interview with The Global Warming Policy Forum. “But some of them were quite — I would say — pushy.”…
