"You have to be mature enough to recognize something can be true even if you don't like the consequences of it. That's what it means to be a mature adult." - Niel Degrasse Tyson
"All climate scientists should announce they're going to take their entire life savings and invest in industries that will thrive under the conditions of global warming. All those in denial of global warming -- which tends to be some of the wealthier people of the nation -- won't do that. As global warming unfolds, that will be the greatest inversion of wealth the world has ever seen. That's all it takes," said Tyson, adding with a smile and a shrug, "I could get rich off this." - Niel Degrasse Tyson
I told you I am a big fan of Niel Degrasse Tyson....he was challenged on climate change and global warming and this is what he said. Someone who is a leading physicist in the WORLD: (the best part starts at 2:10)
and here is a study that was done by 21 scientists from 17 different institutes from 7 nations around the world:
"The Arctic is on the move. The North Pole is in the same place, but Arctic conditions have begun to shift. A study of 30 years of satellite data confirms that the difference in temperatures between the seasons has diminished.
Conditions now have shifted the equivalent of four or five degrees of latitude southward. At the same time, vegetation has moved north, colonizing the thawing permafrost.
Studies show vegetation now growing nearly 500 miles further north than it did just a few decades ago.
A team of 21 scientists from 17 institutions in seven nations reports in Nature Climate Change that as the cover of snow and ice has diminished and retreated in the Arctic Circle, the temperatures have begun to increase — at differing rates — during the four seasons. Although conditions differ from region to region, overall the growing season is beginning earlier, and the autumn freeze is starting later.
Conditions in northern latitudes now increasingly resemble those found several hundred miles further south 30 years ago. One of the authors, Bruce Forbes of the University of Lapland in Finland, told the Climate News Network that in his own research region of north-west Siberia “we are seeing more frequent and longer-lasting high pressure systems. In winter, the snow cover comes later, is deeper on average than in the 1960s, but is melting out earlier in spring.”
Climate is a complicated business, and there is always legitimate room for argument about the validity of one selected set of measurements, a potential bias in the observations, or the reliability of comparison data collected two generations earlier.
But vegetables can’t be fooled. Plants grow where they can. If deciduous shrubs are growing taller, and colonizing sites ever further north, then conditions must be getting warmer, and staying warmer."
