The Consumer Electronics Show has kicked off today in Las Vegas. It's one of the biggest trade-shows in the world and a major trend-setter in the electronics world. Plus, organizers say it's the greenest trade-show in the world.

 

CES has a list of its environmentally-friendly features, which include green products and new alternative energy technologies. The organizers also say 68% of all the waste from last year's show was recycled, and even the wall paper, carpets and toiletpaper used in this year's convention are made from recycled materials. They also took batteries and light bulbs from landfills.

 

Maybe the coolest green display at CES is the Electric Vehicle TechZone, which boasts 3,500 square feet of high and low speed electric autos. Carmakers like Audio, Toyota and Ford will show off the latest green technology in the auto industry, which should be an interesting display. You can follow along at http://cesweb.org/.

As we ring in 2011, the United Nations is inviting everyone to celebrate the International Year of Forests. The UN wants to raise awareness about the importance of forests on our planet and educate people about the issues facing our forests today. And, organizers hope the year-long tribute will inspire people to take action and contribute to forest preservation around the world.

 

According to the UN, forests cover 31% of total land area on the planet and account for 80% of our terrestrial biodiversity. They also provide a home for more than 300 million people worldwide. And, an incredible 1.6 billion people depend on forests for their livelihood–from making and trading important products to farming, and so on.

 

You can find a detailed list of events and celebrations taking place across the globe on the UN's website. One of the major events will be the International Forest Film Festival that takes place at UN headquarters in New York in February. The festival features a series of international films that address different themes, like 'Living Forests,' 'Issues & Solutions,' and 'This is My Forest.' You can check out some clips from the finalists here.

Germany's Alexander von Humboldt Foundation awards scholarships to young people from emerging and developing nations. They spend time in Germany working with organizations or studying at universities, gaining expertise on how to improve climate protection in their home countries. GLOBAL IDEAS met up with one of these scholarship holders: Kristy Pena Munoz, an environmental engineer from Mexico. She's an expert on biogas extracted from sewage sludge.

If you haven't noticed, winter has been especially harsh this year. Much of Northern Europe is in a deep freeze, and any passengers flying through London, Frankfurt or Paris know all too well what this winter has done to travel plans. The U.S. and Canada have been slammed with major snow storms that have left people stranded and desperate during the holiday season. And it's only December…

 

Some people are wondering: if the planet is getting warmer, why is it so cold? The New York Times has an interesting op-ed article about the reasons behind this trend. The author, Judah Cohen, says increased snow cover in Siberia actually has a major impact on our climate–but he believes scientists have ignored the region's role in warming and cooling earth.

 

Cohen says snow cover in Siberia has changed jet stream patterns, pushing more air north and south rather than just east and west. That's why Northern Europe and the U.S. have seen such extreme winter weather in recent years. What do you think? Is Cohen's theory a good explanation?

Researchers are drilling under the Dead Sea in Israel–almost 800 meters below sea level, to be exact. Why? Scientists are collecting rock samples far underneath the water level because they believe those sediments will be extremely well-preserved, and they could reveal some important clues about earth's history.

 

The International Continental Scientific Drilling Program (ICDP) includes a team of researchers from around the world, and they think the rocks they find under the Dead Sea will paint a much clearer picture of climate change history in the area around Bethlehem. So far, the workers have already drilled through around half a million years worth of sedimentary rock, which has helped them learn more about earthquake activity in the region.

 

And what researchers learn in Israel could help them understand more about climate change across the planet. One scientist who's taking part in the drilling mission said the group's findings will have a major impact on science and environment studies, and they could tell us a lot about natural resources in the area.
