Solar scientists worldwide are working to disprove the hypothesis that man is primarily responsible for climate change, according to Dr. Jeff Kuhn, Associate Director of the Institute for Astronomy at the University of Hawaii. In the view of Dr. Kuhn and other top scientists, the Sun changes Earth’s climate. “As a scientist who knows the data, I simply can’t accept (the claim that man plays a dominant role in Earth’s climate),” he states.
Dr. Kuhn last week announced breakthrough research on the role of the Sun – after years of precise satellite measurements, undistorted by Earth’s stratosphere, he and his team discovered that the Sun did not change much in size, as has generally been believed. Rather, the Sun is surprisingly stable, its diameter changing by less than one part in a million during the last 12 years.
Dr. Kuhn’s team, which includes scientists from Stanford University in California and Universidade Estadual de Ponta Grossa in Brazil, used NASA’s SOHO satellite to obtain resolutions 10 times better than telescopes on Earth, allowing them to measure the Sun’s diameter of approximately 865,000 miles to an accuracy of a few hundred feet. In 2017, when the world’s most powerful telescope -- his institute’s Advanced Technology Solar Telescope -- starts operating on Hawaii’s Mt. Haleakala's summit at a resolution 10 times better still, he expects to zero in on details that unravel the mystery of how minute changes on the Sun’s surface affect climate on Earth. NASA’s SOHO satellite revealed that 100 metre high bumps 90,000 kilometres apart cover the Sun’s surface. With his new telescope, Dr. Kuhn expects to capture never-before-seen details of the solar surface.
“We can’t predict the climate on Earth until we understand these changes on the sun,” concludes Kuhn.
