Global consumption of coal dropped by 1.7% last year. This is a major change considering that it had increased by an average of 1.9% per year from 2005 to 2015. China, which accounts for about half of the coal burned in the world, used 1.6% less in 2016, as compared to an increase of 3.7% per year over the previous 11 years.
We are well-aware of the negative effects of air pollution on human health and on the environment, but a recent study at Duke University has revealed that global solar energy production is taking a major hit due to air pollution and dust.
The Paris Climate Agreement seeks to reduce global carbon emissions. The nearly 200 countries who signed it have pledged to reduce their own emissions within their borders. And therein lies the rub: the agreement says nothing about the impact their products have across the world. For some countries, the problem is not so much the emissions they produce; it is those they export.
Global weather patterns are influenced by environmental conditions in places around the world. One of the world’s major weather creators is the Sahara Desert. The Sahara is the largest hot desert in the world. The only larger deserts of any sort are in the polar extremes of the planet and are thus not hot deserts at all.
Back in February, we did a story about a rapidly-growing crack in the fourth-largest ice shelf in Antarctica. At that time, the crack in the Larsen C ice shelf was more than 100 miles long and was growing at a pace of about 5 football fields a day.
According to the Roundtable on Sustainable Palm Oil or RSPO, almost 12 million tons, or 21% of the global supply of palm oil, is now certified as responsible and sustainable. The massive expansion of palm oil plantations has been one of the primary causes of global deforestation. This has been especially the case in Borneo, where 85% of global palm oil production takes place.
It’s estimated that five to thirteen million tons of plastic enters our oceans annually, where much of it can linger for hundreds of years. According to a report by the World Economic Forum and the Ellen MacArthur Foundation, scientists estimate that there is 165 million tons of plastic swirling about in the oceans right now. And we are on pace to have more plastic than fish (by weight) in the world’s oceans by 2050. That’s some scary stuff.
Trees are nature’s way of removing carbon dioxide from the atmosphere. Growing plants take up CO2 and store it in the form of their roots, stems and leaves. And in fact, a significant factor in the growing levels of carbon dioxide in the atmosphere has been the extensive deforestation that has gone on over the past couple of centuries.
The world’s largest floating solar power plant is now operational and connected to the electric grid in China. It is a 40-megawatt facility and floats in water 13 to 30 feet deep in a lake that was created by a former mining operation.
Last December, the first commercial offshore wind farm in the United States started operation off the coast of Rhode Island. The Fisherman’s Energy Atlantic City Windfarm off the coast of New Jersey is under construction. With the lengthy logjam finally broken, there is increasing activity in the emerging U.S. offshore wind sector.
A new carbon capture plant, sitting on top of a waste incineration facility near Zurich, Switzerland, is now sucking CO2 out of the air to sell to its first customer. The plant opened on May 31, and is the first commercial enterprise of its kind.
The changing climate is having a marked effect on forests in this country. In particular, trees along the U.S. eastern seaboard are changing their range as they slowly seek to escape rising temperatures.
The Pitcairn Islands are a group of four volcanic islands in the South Pacific, mostly known from the famed mutiny on the British ship Bounty. Pitcairn Island itself is where many of the mutineers settled and where some of their descendants live today. That small island, with a population of 57, is the only one of the group that is inhabited.
Researchers in Belgium have engineered a device that uses sunlight to purify polluted air and, in the process, produces hydrogen gas that can be stored and used for power. Two teams of researchers separately investigating processes for air purification and hydrogen production combined their efforts to create the new device.
There are an estimated 84,000 dams in the United States which impound 600,000 miles of river, or about 17% of the rivers in the country. Within the next 15 years, more than 90% of the world’s rivers will be fragmented by at least one dam.
The amount of solar energy striking the surface of the earth in two hours is enough to supply all of humankind’s needs for an entire year. For this reason, it is widely thought that solar energy should be our primary source of electricity. If this is to happen, however, there must be cost-effective ways to obtain solar electricity regardless of the time of day, weather, or seasonal changes. Essentially, there must be ways to store the energy from the sun to use it when we need it.
Borneo is the third-largest island in the world, home to part of Indonesia, part of Malaysia, and the small sultanate of Brunei. It is also home to the oldest forest on earth – 130 million years old – which is more than twice as old as the Amazon rain forest.
China and India have 36% of the world’s population and produce about 35% of global CO2 emissions, ranking first and third respectively in that category. The United States, with a little over 4% of the world’s population, produces about 16% of global CO2 emissions, good for second place.
The frozen landscape of Antarctica is getting greener. Researchers drilling into layers of moss that have been accumulating in Antarctica over the last 150 years have found that the growth rate of the moss has been speeding up over the past 50 years.
Poor air quality is a problem all around the world. Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year, making it the fourth largest threat to human health, trailing only high blood pressure, dietary risks, and smoking.
