Warmer winters and more fresh water input from melting have shortened the duration of ocean convection in the last decade

  The temperature and salinity of seawater are key drivers for the global ocean circulation system. Warm and saline water transported poleward cools at the surface when it reaches high latitudes and becomes denser and subsequently sinks into the deep ocean. This process is called convection. At depth, the water is circulated back towards the equator drawing new water masses …

Water stress, soil, and oceans at risk

About 40 percent of the world’s food depends on irrigation, which draws largely from stores of underground water, called aquifers, which make up 30 percent of the world’s freshwater. Unfortunately, groundwater is being rapidly depleted worldwide. In the United States, the Ogallala Aquifer—one of the world’s largest underground bodies of water—spans eight states in the High Plains and supplies almost …

It takes just 4 years to detect human-induced ocean warming

Excerpt from the Guardian.com, Sept 2017 Global ocean heat content data isn’t as noisy as land-based and surface temperatures.  It represents the total thermal energy in the ocean waters, and is now known with a high degree of certainty (see the figure below), in part because scientists have improved ocean temperature sensing methods and increased the number of sensors throughout …

Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change

August 21, 2017 University of British Columbia read full ScienceDaily article here …A new study by researchers at the University of British Columbia provides a deeper explanation of why fish are expected to decline in size. “Fish, as cold-blooded animals, cannot regulate their own body temperatures. When their waters get warmer, their metabolism accelerates and they need more oxygen to sustain …

David Suzuki: Not looking away…We can and must stop dramatically cut down on our use of fossil fuels and plastics

By David Suzuki, EcoWatch, 24 May 2017 People who deny that humans are wreaking havoc on the planet’s life-support systems astound me. When confronted with the obvious damage we’re doing to the biosphere—from climate change to water and air pollution to swirling plastic patches in the oceans—some dismiss the reality or employ logical fallacies to discredit the messengers.  It’s one …
