Slideshow - Climate Change is Real - The Inconvenient Truth

In 2009, Al Gore followed up with the publication of Our Choice: A Plan to Solve the Climate Crisis, a book that "gathers in one place all of the most effective solutions that are available now and that, together, will solve this crisis". "It is now abundantly clear that we have at our fingertips all of the tools we need to solve the climate crisis. The only missing ingredient is collective will."








00:20:19 One thousand years of temperature history obtained from isotope analysis of ice cores.

00:16:08 Measured since 1958, atmospheric carbon dioxide (CO2) has been increasing steadily.





00:20:53 One thousand years of CO2 and temperature data -- the curves have similar shape.






00:22:49 650,000 years of CO2 and temperature history, from Antarctic ice cores. Dips record ice ages. CO2 concentration and temperature are related. CO2 has spiked upward in recent years.






00:23:53 If no changes are made, CO2 concentration is predicted to climb much higher (to 600 ppm) in 45 yea…

The Florida Peninsula at Night from Space

Astronauts aboard the International Space Station took this photograph of Florida in October 2014. The peninsula is highly recognizable even at night, especially when looking roughly north, as our map-trained brains expect.


Astronaut photograph ISS041-E-74232 was acquired on October 13, 2014, with a Nikon D3S digital camera using a 24 millimeter lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by the Expedition 41 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photograph…
