Melting ice sheets changing the way the Earth wobbles on its axis, says Nasa

2016-04-09 02:35:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: Global warming is changing the way the Earth wobbles on its polar axis, a new Nasa study has found. Melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth. And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published on Friday in the journal Science Advances. Scientists and navigators have been accurately measuring the true pole and polar motion since 1899, and for almost the entire...

NASA examines El Nino's impact on ocean's food source

2016-04-07 01:05:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: El Nino years can have a big impact on the littlest plants in the ocean, and NASA scientists are studying the relationship between the two. In El Nino years, huge masses of warm water -- equivalent to about half of the volume of the Mediterranean Sea -- slosh east across the Pacific Ocean towards South America. While this warm water changes storm systems in the atmosphere, it also has an impact below the ocean's surface. These impacts, which researchers can visualize with satellite data, can ripple...

NASA Maps Miles Of Fungi Networks To Predict Which Forests Will Survive Climate Change

2016-04-02 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Inquisitr: There is an entire world beneath the soil, an intricate network of fungi that stretch for miles in immense communities. In a forest, this fungi plays a critical role in the ecosystem and may help scientists map the effect climate change has on the Earth`s precious trees. The underground forest of fungi can be mapped from space, and NASA`s Jet Propulsion Laboratory has gotten involved in an exhaustive attempt to map these huge fungal networks using satellites, United Press International reported....

Fungi can help NASA deduce how climate change affects forests

2016-04-02 04:03:00| Climate Ark Climate Change & Global Warming Newsfeed

Engadget: A team from NASA's Jet Propulsion Laboratory has developed a new method to detect what kind of mycorrhizae are attached to the roots of trees using only satellite images. Mycorrhizae are fungi that form mutually beneficial relationships with the roots of trees, increasing the plants' absorption capability and providing them with direct access to sugars. There are two types of mycorrhizae, and each tree/plant species is only associated with either one of them. Since the two respond differently to...
