Satellite data shows that the Arctic ice cap has GROWN 43% since 2012
Another global alarming alarmist myth bites the dust.
from Daily Mail:
The speech by former US Vice-President Al Gore was apocalyptic. ‘The North Polar ice cap is falling off a cliff,’ he said. ‘It could be completely gone in summer in as little as seven years. Seven years from now.’
Those comments came in 2007 as Mr Gore accepted the Nobel Peace Prize for his campaigning on climate change.
But seven years after his warning, The Mail on Sunday can reveal that, far from vanishing, the Arctic ice cap has expanded for the second year in succession – with a surge, depending on how you measure it, of between 43 and 63 per cent since 2012.
To put it another way, an area the size of Alaska, America’s biggest state, was open water two years ago, but is again now covered by ice.
The most widely used measurements of Arctic ice extent are the daily satellite readings issued by the US National Snow and Ice Data Center, which is co-funded by Nasa. These reveal that – while the long-term trend still shows a decline – last Monday, August 25, the area of the Arctic Ocean with at least 15 per cent ice cover was 5.62 million square kilometres.
This was the highest level recorded on that date since 2006, and represents an increase of 1.71 million square kilometres over the past two years – an impressive 43 per cent.
Other figures from the Danish Meteorological Institute suggest that the growth has been even more dramatic. Using a different measure, the area with at least 30 per cent ice cover, these reveal a 63 per cent rise – from 2.7 million to 4.4 million square kilometres.
With a ground resolution of about 1 km per pixel at the closest point to the surface, ESA’s Mars Express captured this phenomenal view of the Red Planet’s south polar ice cap, cratered highlands and Hellas Basin.
The image was acquired by the high-resolution stereo camera on ESA’s Mars Express on 25 February 2015. It is a ‘broom calibration’ image, acquired while the spacecraft performed a maneuver such that its camera pans over the surface far above the planet, at about 9 900 km.
Mars is a cold desert world, and is the fourth planet from the sun. It is half the diameter of Earth and has the same amount of dry land. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to exist for long on the surface. There are signs of ancient floods on the Red Planet, but evidence for water now exists mainly in icy soil and thin clouds.
Earth has one, Mars has two…moons of course! Phobos (fear) and Deimos (panic) are the Red Planet’s two small moons. They are named after the horses that pulled the chariot of the Greek war god Ares, the counterpart to the Roman war god Mars.
The diameter of Mars is 4220 miles (6792 km). That means that the Red Planet is twice as big as the moon, but the Earth is twice as big as Mars.
Since Mars has less gravity than Earth, you would weigh 62% less than you do here on our home planet. Weigh yourself here on the Planets App. What’s the heaviest thing you’ve ever lifted? On Mars, you could have lifted more than twice that! Every 10 pounds on Earth only equals 4 pounds on the Red Planet. Find out why HERE.
Mass is the measurement of the amount of matter something contains. Mars is about 1/10th of the mass of Earth.
Mars and Earth are at their closest point to each other about every two years, with a distance of about 33 million miles between them at that time. The farthest that the Earth and Mars can be apart is: 249 million miles. This is due to the fact that both Mars and Earth have elliptical orbits and Mars’ orbit is tilted in comparison with the Earth’s. They also orbit the sun at different rates.
The temperature on Mars can be as high as 70 degrees Fahrenheit (20 degrees Celsius) or as low as about –225 degrees Fahrenheit (-153 degrees Celsius). How hot or cold the surface varies between day and night and among seasons. Mars is colder than Earth because it is farther from the sun.
You know that onions have layers, but did you know that Mars has layers too? Like Earth, Mars has a crust, a mantle and a core. The same stuff even makes up the planet layers: iron and silicate.
Ever wonder why it’s so hard launching things to space? It’s because the Earth has a log of gravity! Gravity makes things have weight, and the greater the gravity, the more it weights. On Mars, things weigh less because the gravity isn’t as strong.
Take a deep breath. What do you think you just breathed in? Mostly Nitrogen, about a fifth of that breath was Oxygen and the rest was a mix of other gases. To get the same amount of oxygen from one Earth breath, you’d have to take around 14,500 breaths on Mars! With the atmosphere being 100 times less dense, and being mostly carbon dioxide, there’s not a whole lot of oxygen to breathe in.
Mars has about 15% of Earth’s volume. To fill Earth’s volume, it would take over 6 Mars’ volumes.
A warmer Arctic could permanently affect the pattern of the high-altitude polar jet stream, resulting in longer and colder winters over North America and northern Europe, US scientists say. The jet stream, a ribbon of high altitude, high-speed wind in northern latitudes that blows from west to east, is formed when the cold Arctic air clashes with warmer air from further south. The greater the difference in temperature, the faster the jet stream moves. According to Jennifer Francis, a climate expert at Rutgers University, the Arctic air has warmed in recent years as a result of melting polar ice caps, meaning there is now less of a difference in temperatures when it hits air from lower latitudes. “The jet stream is a very fast moving river of air over our head, but over the past two decades the jet stream has weakened. This is something we can measure,” she said Saturday at a meeting of the American Association for the Advancement of Science. As a result, instead of circling the earth in the far north, the jet stream has begun to meander, like a river heading off course. This has brought chilly Arctic weather further south than normal, and warmer temperatures up north. Perhaps most disturbingly, it remains in place for longer periods of time.

It’s official: When the sea ice that blankets the Arctic Ocean hit its yearly peak on Feb. 25, the maximum area was a record low. Warm temperatures in parts of the polar regions kept sea ice levels depressed, and also contributed to the winter peak occurring much earlier than usual, the National Snow & Ice Data Center announced Thursday. The maximum normally isn’t reached until early March, but was recorded about a week early this year, the NSIDC said. That low occurred on the backdrop of overall dwindling sea ice levels, fueled by global warming.
Earth in Full View : The Apollo 17 crew caught this breathtaking view of our home planet as they were traveling to the moon on Dec. 7, 1972. Its the first time astronauts were able to photograph the South polar ice cap. Nearly the entire coastline of Africa is clearly visible, along with the Arabian Peninsula.
