The Changing Face Of Air Pollution
Air pollution in cities is a global problem that has reached crisis proportions in places like China and India. In our country, since the Clean Air Act was passed in 1970, there has been a great deal of effort exerted in controlling pollution from vehicles. A combination of pollution-limiting changes to engines, fuels, and pollution control systems has significantly reduced the amount of air pollution associated with the transportation sector.
Deepwater Aquaculture
Near-shore fish farms have created many environmental problems. Raising large numbers of fish creates concentrations of fish waste and sea lice, which can adversely impact near-shore ecosystems.
2017 Was Hot
There’s no argument to be made about whether 2017 was hot or not. The only uncertainty is whether it was the second or third warmest year ever recorded.
Endangered Chocolate
There are many scary stories floating about with regard to dire potential consequences of climate change, but one that should really strike fear into many of our hearts is the prediction from scientists at the National Oceanic and Atmospheric Administration that cacao plants are likely to go extinct as early as 2050 as a result of the changing climate.
Is The World’s Largest Sea Turtle No Longer Endangered?
The rapid disappearance of many plants and animals around the world has many scientists saying we are experiencing a sixth mass extinction – the first since the dinosaurs were wiped out some 66 million years ago. Despite all sorts of conservation efforts, living things are struggling as a result of climate change, habitat loss, and countless other natural and manmade pressures. Conservation success stories have been few and far between.

Winter Outlook
Each year around this time, the National Oceanic and Atmospheric Administration, or NOAA, releases its U.S. Winter Outlook that predicts overall weather trends around the country for the upcoming winter. They produce these seasonal outlooks to help communities prepare for the weather that is likely to be forthcoming.
Invasion Of The Sea Pickles
Sea pickles are translucent, tubular creatures that are usually found in tropical ocean waters. Also known as pyrosomes, they are actually made up of many small multicellular organisms that are linked together in a tunic to form a tubelike colony that is closed on one end.
Carbon From The Alaskan Tundra
The soils that encircle the northern reaches of the Arctic are a vast repository for carbon in the form of undecayed organic matter from dead vegetation. The enormous amount of material trapped in the permafrost contains enough carbon to double the current amount of carbon dioxide in the Earth’s atmosphere.
Carbon Dioxide Continues To Rise
Back in December of 2013, a little less than three years ago, Earth Wise reported that the observatory on Mauna Loa in Hawaii had briefly measured carbon dioxide levels greater than 400 parts per million for the first time ever. During the following year, readings above the 400 level started to pop up occasionally elsewhere as well.
