Climate Change Demostrators

The New York rally was part of a global protest that included events in 156 countries - Afghanistan, the UK, Italy and Brazil among them.

Demonstrators urged Prime Minister Tony Abbott to take action, citing fears that climate change could lead to more bushfires and droughts.Organizers said more than 25,000 marched in Paris and  15,000 people marched in Berlin, urging world leaders to recognize climate change as a top pressing problem.

Richard Gray Reconstruction of Neanderthal face

The face of a modern human is almost uniquely flat and extraordinarily expressive. But our remarkable faces may not be as "modern" as we think. (A reconstruction of a Neanderthal face is illustrated above). These reconstructed faces look impassive, but a range of emotions are painted onto visitors' faces at the Natural History Museum in London.

There were folks dressed in lab coats and pink knit brain hats. There were costumed characters and festooned pets. And there were many, many signs. Across the nation and abroad, as thousands of scientists and their supporters convened on Earth Day to defend science against proposed government cuts and political interference, many got their messages across with colorful and candid protest signs.  Here are some of the best signs we have seen

 West Antarctic in red has 002

Glaciers in Antarctica are melting faster and across a much wider area than previously thought, a development that threatens to raise sea levels worldwide and force millions of people to flee low-lying areas, scientists said in Geneva during a conference in February 2017.. Researchers once believed that the melting was limited to the Antarctic Peninsula, a narrow tongue of land pointing toward South America. But satellite data and automated weather stations now indicate it is more widespread.

Analemma

A lemniscate is any of several figure-eight orshaped curves. The word comes from the Latin "lēmniscātus" meaning "decorated with ribbons", from the Greek λημνίσκος meaning ribbons.  In astronomy, an analemma (from Greek ἀνάλημμα analēmma "support") is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on the Earth. An analemma can be traced by plotting the position of the Sun as viewed from a fixed position on Earth at the same clock time every day for an entire year, or by fixed camera taking time lapse pictures throughout one year. The resulting curve resembles a long, slender figure-eight with one lobe much larger than the other, known as a lemniscate of Bernoulli.
