The most recent report from the UN Intergovernmental Panel on Climate change includes discussion of a number of extreme and untested solutions to the climate crisis.  Among these are solar geoengineering – modifying clouds or spraying tiny reflective particles into the upper atmosphere in order to block some of the sun’s light and thereby cool […]

The Tana River is the longest river and most important waterway in Kenya.  It flows 620 miles from its headwaters in the Abderdare mountain range and Mount Kenya to the Indian Ocean.  The Tana River produces approximately half of the country’s electricity, and supplies Nairobi, the capital of Kenya, with 80% of its water.    According […]

There are millions of wild pigs in the world with the largest numbers in the United States and Australia but significant numbers in South America, Europe, and China.  In the US, there are as many as 9 million feral swine living in 38 states.  A conservative estimate indicates that they cause about $1.5 billion in […]

According to a new Swedish study recently published in the Journal of Industrial Ecology, men spend their money on greenhouse gas-emitting goods and services, such as meat and fuel, at a much higher rate than women.  The study looked at the carbon emissions created by consumption among categories like food, clothing, furniture, and vacations to […]

The record-breaking heatwaves this summer have exposed the special vulnerability inner cities have to the effects of summer heat.  Climate change has exacerbated and supercharged heatwaves, as was seen in Seattle and Portland in late June. Urban cores can be 10 degrees or more warmer than the surrounding countryside.  The urban heat island effect is […]

A newly released study has found that mountaintop glacier ice in the tropics of all four hemispheres has diminished dramatically over the past 50 years.  Among the findings of the study, published in the journal Global and Planetary Change, are that a glacier near Puncak Jaya, in Papua New Guinea, lost about 93% of its […]

The world produces over 300 million tons of plastics each year, mostly produced from petroleum.  The environmental consequences are substantial and there is a critical need to replace as much of that plastic production with biodegradable plastics as possible.  Thus, there is global research aimed at making bioplastics more economical and as environmentally friendly as […]

The precarious state of the world’s coral reefs has been a highly visible subject for a decade or more.  Mostly what we hear about is the loss of some of the most beautiful sights on the planet. But there is far more at stake than scenic wonders. The warming and acidifying of ocean waters are […]

Russia is the largest country in area in the world, almost equal in size to the sum of the next two largest – Canada and the U.S.   Russia is also the world’s largest forest country, containing more than one-fifth of the world’s forests.  As a result, the country’s forests and forestry activities have enormous potential […]
