WWF What is climate change? Global warming – doesn’t mean we’ll all just have warmer weather in future. As the planet heats, climate patterns change. It’ll mean more extreme and unpredictable weather across the world – many places will be hotter, some wetter, others drier. Your meat addiction is destroying the planet “Jesus,” Molly said, her own plate empty, “gimme that. You know what this costs?” She took his plate. “They gotta raise a whole animal for years and then they kill it. This isn’t vat stuff.”

Space for Kids - Earth - The Threat of Melting Ice About 20,000 years ago, much of Europe, Asia, North and South America was covered by huge sheets of ice, each many kilometres thick. Since then, the ice has gradually melted and the ice sheets have retreated. Today, the only ice sheets on Earth’s land masses are found in Antarctica and Greenland. Some ice also occurs as glaciers in mountainous regions and as floating ice floes in the Arctic Ocean and around Antarctica. At first glance, these remote left-overs from the last Ice Age seem of little significance for most of us today.

How Wind Turbines Works Share 12Share Wind Energy has been used since several years to power homes, sail boats, pump water from wells or heating and cooling homes and offices. Today with the ever increase in the demand for fossil fuels and with the prices soaring all time high numerous resources have been invested in the wind energy. The clearest proof we’ll ever get that our planet is falling apart Every once in a while, a chart or statistic or image comes along that reminds us, all over again, why it is that this global warming thing is so terrifying. This week, it was those darn walruses, who — after a summer when Arctic sea ice was at its sixth-lowest level on record — mobbed an Alaska beach in the largest such haul-out ever observed there. Salon was on the story. So, too, was pretty much everyone else who writes about climate issues, and we were all trying to get across the same basic idea: Those 35,000 walruses with nowhere else to go are climate change. Or at least, one of the best ways we have of understanding it. It’s not surprising the photos went viral — they’re a powerful, charismatic representation of dramatic changes that are happening in real-time.

Decline in snowpack shows Calif. will have to manage its water differently LOS ANGELES — On Thursday, California workers poked hollow aluminum tubes into Sierra Nevada meadows to measure the snowpack. They did not find much. “We will conceivably see more years like this in the future,” said Jeffrey Mount, a geologist with the Public Policy Institute of California. The Earth has been getting warmer, scientists say, and the climate is expected to keep getting warmer.
