Cryptocurrency And Climate Change

January 23, 2018 By EarthWise Leave a Comment

https://earthwiseradio.org/wp-content/uploads/2018/01/EW-01-23-18-Cryptocurrency-and-Climate-Change.mp3

Bitcoin is a form of digital currency.  Bitcoins aren’t printed, like dollars or euros.  They are produced by people and businesses using computer software to perform the necessary complex calculations.  A bitcoin is essentially a line of computer code that’s signed digitally when it goes from one owner to another.  Bitcoin is the most prominent example of a growing category of money known as cryptocurrency.

Disappearing Kelp Forests

In recent decades, ocean temperatures in many places have warmed by nearly 3 degrees Fahrenheit.  An effect of this warmer water is the decimation of what were once luxuriant giant kelp forests in eastern Australia and Tasmania.  There used to be thick canopies covering much of the region’s coastal sea surface, but they have wilted in the intolerably warm and nutrient-poor water.

Taking the bus in crowded cities is a good way to reduce overall traffic, save money on gas, and do a good turn for the environment.   Unfortunately, bus riders often are exposed to large amounts of pollution in the process.

The Hawaiian Islands are an archipelago of eight major islands, several atolls, numerous smaller islets, and seamounts in the North Pacific Ocean.  The islands are a world-renowned vacation spot, known for their white-sand beaches, lush flora, and near perfect weather.  But stormier days may be ahead.

Germany’s Struggle

Germany has a reputation as one of the greenest countries on earth.  They have comprehensive recycling programs, they treasure their forests, and in recent decades, they have been aggressively working to replace both nuclear and coal-fired power plants with renewable energy sources.  They have been an early world leader in solar power.  And their national Energiewende or “energy turn” initiative demonstrates a strong commitment to the environment.

There is deservedly a great deal of focus on the effects that carbon pollution is having upon the climate and most countries around the world are working to reduce their emissions.   However, even if climate effects were not a serious threat to humanity, pollution is a deadly menace to human health.

For many, the Christmas tree is a quintessential part of the holiday season.  According to the American Christmas Tree Association, 81% of Christmas trees Americans decorated in 2016 were artificial.  But are artificial trees really the better option for the environment?

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.

Fuel From Greenhouse Gases

Carbon dioxide and methane are the two greenhouse gases that are having the greatest impact on the global climate.  There are basically three ways to prevent them from getting into the atmosphere:  don’t emit them, trap them and store them away, or turn them into something useful.

Carbon And Heating Soil

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.

Vertical farming is a method for producing crops in vertically stacked layers or surfaces typically in a skyscraper, used warehouse, or shipping container.  Modern vertical farming uses indoor farming techniques and controlled-environment agriculture technology.

More Fake Fish News

https://earthwiseradio.org/wp-content/uploads/2017/10/EW-11-20-17-More-Fake-Fish-News.mp3

There has been quite a bit of news in recent years about the mislabeling of fish sold in markets and restaurants.  One study a few years ago concluded that 1/3 of fish sold is not what it is labeled to be. Much of the practice is economic fraud:  substituting cheaper, easier-to-find fish for rarer, more valuable types.  For example, the study found that fish sold as red snapper was almost always not what it claimed to be.  But cheating paying customers is not the only problem associated with the misidentification of fish.

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.

The British discount airline EasyJet recently announced a partnership with American company Wright Electric to develop an all-electric commercial airplane that they said could be flying within 10 years.  The goal of the partnership is to develop aircraft with a maximum range of 335 miles, which is long enough for many of the European routes that EasyJet flies from its hub in England.

According to the National Retail Federation, 179 million Americans are expected to spend $9.1 billion – or nearly $84 per person – on Halloween festivities this year, reaching a new record high.  But it’s not just our wallets that take a beating.  The planet also pays quite a price.

A study by the American Association for the Advancement of Science has produced an estimate of the total amount of plastic manufactured worldwide since the 1950s.  The researchers then measured that data against statistics on recycling, incineration and discard rates.  The results are sobering.

The Effects Of One Degree

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-10-09-17-The-Effects-of-One-Degree.mp3

In discussions of global warming, we often hear about the effects of a 2-degree rise in temperature or a 1-degree rise in temperature.   For most of us, such changes seem pretty insignificant.  Of course, in our daily lives, a one-degree temperature change is not particularly noticeable.   But in the context of climate change, we are talking about a change in average temperature over time, not the temperature on a particular day or at a particular time.

Storing Carbon in the Ocean

As carbon dioxide levels in the atmosphere continue to rise, it may be that clean energy technologies, electric cars, and other methods of reducing emissions may not be enough.  Carbon sequestration – sucking carbon out of the atmosphere – is seen by many as a crucial part of the solution.

New Rules For Ocean Conservation

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-09-21-17-New-Rules-for-Ocean-Conservation.mp3

In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas.  That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions.  The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.
