In May, California became the first state in the U.S. to require solar panels on almost all new homes. Under new standards adopted by the California Energy Commission, most new homes, condos and apartment buildings built after January 1, 2020 will be required to include solar systems.
A couple of years ago, scientists in Japan discovered bacteria at a recycling plant that were breaking down a type of plastic called polyethylene terephthalate, or PET. With the world facing a growing plastic pollution problem, British and American researchers began to study the enzyme that the bacteria were using to try to understand how it works.
Food waste is one of the most disheartening problems we face. Fully one-third of all food produced globally for human consumption is wasted. Fruits, vegetables and tubers are even worse off: fully half of these things are wasted. It is a loss at an economic, social and environmental level.
There is a great deal of concern about the status of pollinators like bees and butterflies. They play a crucial role for many important food crops. But it turns out that lizards, mice, bats and other vertebrates are important pollinators too.
New Jersey may host the second commercially operating offshore wind farm in the U.S. as soon as 2020. The company EDF Renewable Energy is moving forward with a plan to bring online a 24-MW farm sited off the coast of Atlantic City.
The carbon cycle is the biogeochemical process by which carbon is exchanged between the atmosphere, the terrestrial biosphere, the ocean, sediments, and the earth’s interior. Its balance is a key factor that influences the climate.
The global concentration of carbon dioxide in the atmosphere was measured at 400 parts per million for the first time in recorded history in May of 2013. It was a brief event at the Mauna Loa Observatory in Hawaii at the time. Within the next couple of years, however, readings of at least 400 ppm became standard.
The total amount of solar power capacity installed in the world reached 100 gigawatts in 2012. Getting to that amount took decades. But things have changed in dramatic fashion in recent years.
Every year, the Environmental Working Group ranks pesticide contamination in 47 popular fruits and vegetables for its Shopper’s Guide to Pesticides in Produce. The environmental nonprofit has created this ranking annually since 2004.
Engineers from the National University of Singapore have recently discovered that a naturally occurring bacterium is capable of directly converting cellulose to biobutanol, a promising biofuel.
More than half of the world’s people now live in cities so understanding climate issues in cities is crucial. One of the most important city climate effects which has a profound impact on both human health and energy consumption is the Urban Heat Island Effect.
Deserts are barren areas of land where little precipitation occurs, resulting in living conditions that are hostile for plant and animal life. These regions are typically defined by low average annual rainfall—usually 100 millimeters (less than 4 inches) of rain per year or less.
A group of scientists and engineers at McMaster University in Hamilton, Ontario, has developed a new technology that could replace traditional “best before” dates on food and beverages with a definitive indication of the safety of the product.
It sure seems like extreme weather is increasingly common: floods, droughts, extreme rainfall, powerful snowstorms, hurricanes and so on. But we tend to focus on recent events and often give them undue emphasis. So, it is reasonable to ask whether extreme weather really is more common these days.
The Great Pacific Garbage Patch is the world’s largest collection of floating trash. It lies between California and Hawaii and is popularly described as being larger than Texas. It was discovered in 1997 by a yachtsman who sailed through a mess of floating plastic bottles and other debris while on a voyage between Hawaii and Los Angeles.
If we want to avoid drastic global warming this century, we need to sharply reduce greenhouse gas emissions over time. For the previous three years, emissions had been holding steady, but last year, global emissions from the use of coal, oil and natural gas increased by 1.4%. According to the International Energy Agency, this unfortunate new data should serve as a strong warning that we need to increase our efforts to combat climate change.
Last spring, we talked about a solar-powered water harvester designed to pull water out of even dry desert air. The prototype device was described in a paper by scientists at UC Berkeley and MIT in the journal Science.
Many of us are well aware of the environmental challenge faced because of the proliferation of plastics. Since plastic does not decompose naturally, most of it remains in our environment. Only 12% has been incinerated and only 9% has been recycled. A great deal of plastic ends up in the ocean and other bodies of water. Much of it breaks down into small particles – microplastics – which are now ubiquitous in the oceans. There are also microplastics that started out that way in the form of little beads used in the cosmetics industry. Studies have found microplastics in the bodies of 73% of fish from the North Atlantic.
Worldwide, deforestation and land disturbance are responsible for about a quarter of all greenhouse gas emissions. The largest contributor to this problem is Indonesia and getting control of its emissions is a crucial part of meeting global carbon reduction targets.
More and more often we make use of “the cloud” – that mysterious place where we store, move, process and analyze data. We keep our photos there. We stream music and videos from there. We do our work there. Perhaps we have a mental image of all of this digital information floating above our heads in some ethereal way: like in a cloud.
