A comprehensive study has confirmed what has been widely believed in the scientific community and in popular reports for years: spring is arriving earlier and the further north you go, the more pronounced is the effect.
Orangutans are some of the planet’s most intelligent animals. In fact, orangutans and human beings share 97% of their DNA sequence. Orangutans can only be found in the wild in Southeast Asia on the Indonesian island of Sumatra and the island of Borneo, which is a landmass shared by Indonesia, Malaysia, and Brunei. And while all orangutans are endangered, the critically-endangered Bornean orangutans are under exceptional duress.
Climate change continues to pose a major threat to polar bear survival. Polar bears, whose native range largely lies within the Arctic Circle, depend on sea ice for nearly all of their life cycle functions. And rising global temperatures are causing that sea ice to disappear.
Predators and scavengers are widely persecuted by people because they are often harmful to property, livestock, and human beings. Nonetheless, research has shown that many of these animals play important roles in ecosystems and their removal can be quite harmful.
When considering the greenhouse gas emissions associated with any energy source, it is important to look at the total life cycle emissions both from the direct use of the energy source and from the indirect emissions associated with building the system, producing and transporting fuels and other supplies and, ultimately, decommissioning the system. Taking all of this into consideration is necessary in order to have a full accounting of the carbon impact of power sources.
Plants are the world’s great storehouse of carbon dioxide. That is why deforestation is a major contributor to climate change. If only there were more trees and plants, more of the CO2 in the atmosphere would be absorbed and could no longer trap heat in the atmosphere.
Biomimicry is learning from and then emulating nature’s forms, processes, and ecosystems to create more sustainable designs. Mother Nature is already the inspiration for countless products and designs ranging from Velcro copied from plant burs to the shape of wind turbines modeled after whale fins. There are wetsuits inspired by beaver pelts and office buildings that copy termite dens. Increasingly, innovators are looking at nature for designs in architecture, chemistry, agriculture, energy, health, transportation, computing, and even for the structure of organizations and cities.
The Greenland Ice Sheet is the second largest ice body in the world, after the Antarctic ice sheet. It is about 1,500 miles long, nearly 900 miles across at its widest point, and averages more than a mile in thickness. It has experienced record melting in recent years and is a source of great concern as the climate continues to warm. The Greenland Ice Sheet is losing an estimated 270 billion tons of ice each year. If the entire sheet were to melt, global sea levels would rise by 24 feet which, of course, would be a world-wide catastrophe.
Plug-in hybrid vehicles are ones that can run both on electricity provided by a power outlet as well as on gasoline. There are many of them on the market these days built by quite a few car makers. But these vehicles have an undeserved reputation as being the fig leaf of electric mobility. Many environmental organizations and political decision-makers don’t consider them to be “real electric cars.”
There is much to be said in favor of organic food. The organic produce industry took in $65 billion in 2016 and that farming method is clearly increasingly popular and is here to stay. Nevertheless, there are various misconceptions and inaccuracies related to organic food.
According to researchers with the National Geographic Society’s Big Cats Initiative, cheetahs are much closer to extinction than previously thought. The research team has released a study, which was recently published in the journal PeerJ, that updates the cheetah population numbers in southern Africa, the largest of its remaining habitat.
Reducing carbon dioxide emissions is an essential element in mitigating climate change. The best approach is to not produce the stuff in the first place and the ongoing transition away from fossil fuels is trying to do just that. But realistically, fossil fuels will be with us for a long time to come. Given that, additional approaches are necessary.
As the world looks to reduce carbon emissions, many companies are dealing with paying for their carbon emissions as part of the cost of doing business. But apart from the situations in which companies already are required to pay for their carbon emissions, a growing number of companies now build carbon pricing into their business plans even if they are not yet directly paying for their emissions. This practice is known as putting an internal price of carbon into their business plan.
It is now commonplace to see solar panels on the rooftops of homes and businesses. There are more than a million solar homes in the US alone. But a new generation of see-through solar technology has the potential to also turn the windows of buildings and cars, as well as other glass-coated objects, into electricity generators.
There has been a spate of announcements from major car manufacturers in recent times detailing their plans to electrify their future vehicles. General Motors recently announced its “path to zero emissions” plan which includes the introduction of at least 20 electric vehicles by 2023. They are joining Volvo, Volkswagen, Toyota and others in making such an announcement.
Tsetse flies are widespread in Africa. They feed on blood and are the source of the dreaded sleeping sickness, an infection that can be lethal, damages the nervous system and, in its final stage, causes a dozy state, which gave the disease its name. Sleeping sickness is a real danger for people in tropical Africa, but tsetse flies can also transfer the disease to cattle. This leads to huge losses in milk, meat and manpower. The damage caused by the flies in Africa is estimated to be nearly $5 billion a year.
When was the last time you used a squeegee to remove squashed insects from your windshield? It’s been a while, right? It’s not just you. This is known as the windscreen phenomenon. Scientists and some motorists have long suspected that flying insects are in dramatic decline. New research has confirmed these suspicions.
Plants are a critical part of the Earth’s carbon cycle. They take in carbon dioxide during photosynthesis. Eventually, dead leaves, branches and other materials fall to the ground where bacteria and fungi decompose the materials and release the CO2 back into the atmosphere. This carbon-soil feedback loop is a complicated one that is critical to the overall carbon balance because soils actually contain two to three times more carbon than the atmosphere.
The use of neonicotinoid pesticides or neonics has long been suspected as harmful to bees and a major factor in the widespread decline of honeybee and wild bee populations. A study published in Science last June provided strong evidence that neonics are indeed a real problem for bees.
Microplastics, which are tiny pieces of weathered plastic less than 5 millimeters in diameter, have been accumulating in the oceans for the past 40 years and are now ubiquitous in the marine environment. They are a major threat to many kinds of marine life, including numerous species of birds, turtles, fish, marine mammals and invertebrates who ingest the stuff causing a variety of problems.
