Climate change: the effects on ocean animals The “poster child” for global warming is the polar bear. But many other animals are already feeling the effects of global climate change on the oceans. Find out about the changing climate's impact on the earth’s population of sea turtles, right whales, penguins, seals, lobsters, and cod. The Arctic’s top predator, the polar bear, is affected both by the reduction in sea ice and by reduced stocks of its primary food, the ringed seal. Polar bears use sea ice as a platform for hunting their prey and for resting. But sea ice is decreasing throughout their Arctic range due to climate change. As sea ice becomes thinner and multi-year ice disappears, a greater proportion of females make their dens on land, expending more energy to get there. Polar bears are often described as completely dependent on ice for their survival. In 2008, the U.S. Back to top Taken by New England Aquarium Educator Jessica Lavash in Padre Island, Texas. Adult feeding patterns are also affected by climate change.

WWF: Climate change Carbon dioxide, or CO2, is the most significant of the gases in our atmosphere which keep the Earth warm. 4 billion years ago its concentration in the atmosphere was much higher than today - 80% compared to today's 0.03%. But most of it was removed through photosynthesis over time. A natural carbon dioxide cycle keeps the amount of CO2 in our atmosphere in balance. The amount of naturally produced CO2 is almost perfectly balanced by the amount naturally removed.

3,200 Year Old Tree Never Been Captured In A Single Image... (Distractify) Cloaked in the snows of California’s Sierra Nevada, the 3,200-year-old giant sequoia called the President rises 247 feet. Two other sequoias have wider trunks, but none has a larger crown, say the scientists who climbed it. The figure at top seems taller than the other climbers because he’s standing forward on one of the great limbs. The trunk is 27 feet wide and the his mighty branches hold 2 billion needles, the most of any tree on the planet. Giant sequoias exist in only one place, where The President and smaller trees that make up his “House” and “Senate”, reside. The team painstakingly put together a set of pulleys and levers to climb the tree. Awesome stuff. Chael Nichols, Ngm staff. Order Large Format Prints at: NationalGeographicCart.com

The Fairy Tale Forest By Ildiko Neer | Travel Klix Hungarian photographer Ildiko Neer began operations in 2009. He draws his inspiration from nature, but a special thrill is wood – the sun makes its way through the trees, the sound of leaves and stunning colors of autumn. All this was reflected in the works of photographer. This amazing photographer really have the eye for a good nature photo.

What is climate change? Media playback is unsupported on your device BBC News looks at what we know and don't know about the Earth's changing climate. What is climate change? The planet's climate has constantly been changing over geological time. However, the current period of warming is occurring more rapidly than many past events. What is the "greenhouse effect"? The greenhouse effect refers to the way the Earth's atmosphere traps some of the energy from the Sun. The energy that radiates back down to the planet heats both the lower atmosphere and the surface. Scientists believe we are adding to the natural greenhouse effect with gases released from industry and agriculture (known as emissions), trapping more energy and increasing the temperature. The most important of these greenhouse gases in terms of its contribution to warming is water vapour, but concentrations show little change and it persists in the atmosphere for only a few days. What is the evidence for warming? Image copyright AFP What about the pause?

50 Most Beautiful Tree Photos Trees are one of the most important life forms on our planet, as they provide oxygen for the rest of the organisms on Earth through a process called photosynthesis. Although trees come in many varieties, depending on the ecosystem, including pine trees, oak, cedar, redwood, palm trees and more, they all share similar characteristics and are great subjects for photography. Here, you’ll find 50 most beautiful tree photos from the best photographers in the world. Whether it’s a single tree illuminated by a fading sun, or a dense jungle or forest shrouded in mist, these photographs are all incredible in their beauty. So, enjoy the tree photography!

Clean Air Kids: Greenhouse Effect & Global Warming The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The sun is much hotter than the Earth and it gives off rays of heat (radiation) that travel through the atmosphere and reach the Earth. The rays of the sun warm the Earth, and heat from the Earth then travels back into the atmosphere. The gases in the atmosphere stop some of the heat from escaping into space. These gases are called greenhouse gases and the natural process between the sun, the atmosphere and the Earth is called the 'Greenhouse Effect', because it works the same way as a greenhouse. The windows of a greenhouse play the same role as the gases in the atmosphere, keeping some of the heat inside the greenhouse. The atmosphere has a number of gases, often in tiny amounts, which trap the heat given out by the Earth. To make sure that the Earth's temperature remains constant, the balance of these gases in the atmosphere must not be upset. The Weather Sea Levels Farming Water
