Explanation:
Posted on Astronomy Picture of the Day:
Our Sun is still very active. In the year 2000, our Sun went though Solar Maximum, the time in its 11-year cycle where the most sunspots and explosive activities occur. Sunspots, the Solar Cycle, and solar prominences are all caused by the Sun's changing magnetic field. Pictured above is a solar prominence that erupted in 2002 July, throwing electrons and ions out into the Solar System. The above image was taken in the ultraviolet light emitted by a specific type of ionized helium, a common element on the Sun. Particularly hot areas appear in white, while relatively cool areas appear in red. Our Sun should gradually quiet down until Solar Minimum occurs, and the Sun is most quiet. No one can precisely predict when Solar Minimum will occur, although some signs indicate that it has started already!
Scientists have suspected in recent years that Mars might be undergoing some sort of global warming. New data points to the possibility it is emerging from an ice age.

Sun|trek, a new educational solar website
(February 2008)
Sun|trek is an exciting new website for school students and teachers about the Sun and its effect on the Earth. Sun|trek has been motivated and inspired by the fantastic images and movies of the Sun taken from space (for example from the SOHO satellite). It is narrated by solar guides (young solar researchers), who not only share the excitement that they feel about working with these solar space projects, but also say a bit about themselves, how they became interested in astronomy and what their other interests are. They are 'role models' who could inspire the younger students.
- New Phenomena on the Sun
March 21, 2007: It's enough to make you leap out of your seat: A magnetic vortex almost as big as Earth races across your computer screen, twisting, turning, finally erupting in a powerful solar flare. Japan's Hinode spacecraft recorded just such a blast on Jan. 12, 2007.

- CO2 Science: CO2 and the Biosphere:
The Center for the Study of Carbon Dioxide and Global Change was created to disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climatic and biological consequences of the ongoing rise in the air's CO2 content. It meets this objective through weekly online publication of its CO2 Science magazine, which contains editorials on topics of current concern and mini-reviews of recently published peer-reviewed scientific journal articles, books, and other educational materials. In this endeavor, the Center attempts to separate reality from rhetoric in the emotionally-charged debate that swirls around the subject of carbon dioxide and global change. In addition, to help students and teachers gain greater insight into the biological aspects of this phenomenon, the Center maintains on-line instructions on how to conduct CO2 enrichment and depletion experiments in its Global Change Laboratory (located in its Education Center section), which allow interested parties to conduct similar studies in their own homes and classrooms.

New findings indicate today's greenhouse gas levels not unusual
By Dr. Tim Ball and Tom Harris, www.nrsp.com

Monday, May 14, 2007
"Stopping climate change" may be all the rage with celebrities and environmental lobbyists, but fortunately for the rest of us, the scare's scientific foundation is rapidly disintegrating.
One of the fundamental pillars of the hypothesis that humanity is causing dangerous climate change is the belief that levels of carbon dioxide (CO2), the greenhouse gas of concern in countries such as Canada, have been rising steadily since the start of the industrial revolution. But what if CO2 levels have not increased? How could our emissions of this otherwise benign gas then have anything to do with the past century's modest warming?"
