Chinese Academy of Sciences Understanding the responses of the date of autumn foliar senescence (DFS) to climate change is important for a better interpretation of carbon uptake. The high northern latitudes (>50°) experienced a pronounced surface stilling (i.e., decline in winds) with climate change. But its influence on DFS remains unknown. Prof. WU Chaoyang’s team from the Institute of Geographic Sciences and Natural Resources Research (IGSNRR) of the Chinese Academy of Sciences found that decline in winds significantly extended DFS over high northern latitudes at a magnitude comparable ...

It demonstrates the profound impact humans are having on the planet, scientists said. The planet’s geographic north and south poles are the point where its axis of rotation intersects the surface, but they are not fixed. Changes in how the Earth’s mass is distributed around the planet cause the axis, and therefore the poles, to move. In the past, only natural factors such as ocean c...

The locations of the North and South poles aren't static, unchanging spots on our planet. The axis Earth spins around--or more specifically the surface that i...

Credit: Flickr, Derek Keats. Earth’s axis is an invisible line that connects the planet’s geographic north and south poles. However, this axis isn’t fixed since it is a function of the planet’s center of mass, or barycenter, which can change if the planet’s mass is significantly redistributed. This is exactly what happened in the last three decades as a result of global warming, which has melted hundreds of billions of tonnes of ice from the poles, especially the north pole. According to a new study published in the journal Geophysical Research Letters, since 1980, the position of ...
