About 30% of the carbon dioxide emitted by human activity is absorbed by the oceans.  As a result, they are getting warmer and more acidic, and the currents that help shape global weather are shifting.  To try to reduce global warming, people want to be able to store even more carbon dioxide in the oceans […]

The world’s coral reefs are in the midst of a global bleaching event being driven by extraordinarily high ocean temperatures.  This is the fourth such global event on record and is predicted to be the largest one ever.  Coral bleaching occurs when corals are stressed by heat and eject the symbiotic algae within them that […]

Oases are important sources of water for people, plants, and animals in the world’s desert areas.  In fact, oases sustain 10% of the world’s population despite taking up only about 1.5% of land area.  They form when groundwater flows and settles into low-lying areas or when surface meltwater flows down from nearby mountains and pools. […]

Wind power has become one of the most affordable ways to generate electricity as well as being renewable and not contributing to global warming.  But there has been the perception that wind farms require a lot of land compared with fossil fuel power plants. This issue of land use has made decision-makers reluctant to invest […]

The warming climate is changing the distribution of fish species.  Researchers at the University of Adelaide in Australia have observed that tropical fish species are moving into temperate Australian waters. The Eastern Australian Current is strengthening as the climate warms and larvae of tropical fish are getting caught in the current and moving into more […]

The world is facing the biggest deficit of cocoa in decades. Most cocoa beans are grown in West Africa, where climate change-induced drought has ravaged crops.  Harvests are forecasted to fall short for the third consecutive year.  The harvest shortfall has triggered a steep rise in cocoa prices.  In fact, cocoa prices have more than […]
