Coronavirus Shutdowns And The Environment | Earth Wise

Our stories often discuss how human activities change the natural environment. With most of us confined to our homes, the lack of human activities is having profound effects on the environment. We are talking about some of these this week.

The COVID-19 pandemic is a global catastrophe, but it has ironically been a boon for the environment. By taking billions of people off the streets around the globe and slashing all forms of travel, the global environment has seen dramatic changes.

Sea turtles in many countries are prospering by not having to compete with humans for precious beach space. Animals everywhere have more freedom to roam and are taking advantage of the opportunity. The Himalayas are visible from parts of India for the first time in decades.

Satellite imagery has shown dramatic drops in nitrogen dioxide emissions in China, where pollution from vehicles is a serious public health problem. Similar reductions in air pollution are evident in India, Italy and even in Los Angeles. The city that is notorious for its smog suddenly has pristine air.

In Venice, water in the canals has become clear in the absence of heavy boat traffic stirring up sediments from the bottom. Wildlife that normally is invisible such as jellyfish are being spotted.

Not all the changes to animal behavior are desirable. Some wildlife that have become dependent on humans as a source of food are becoming aggressive and are taking to the streets of cities to look for food. Monkeys in Thailand are mobbing towns and brawling, hunting for things to eat. Rats in New York City are fighting over suddenly meager food supplies.

In many ways, the natural world is reacting to much of humanity sheltering in place.

Scandinavian Wine

December 20, 2019 By EarthWise Leave a Comment

The warming climate is creating some unexpected entrepreneurial opportunities. Many places that have traditionally dominated the wine industry are starting to be worried that the local climates that made them ideal for vineyards are changing and becoming much less ideal. On the other hand, places where wine-making was regarded as a losing proposition are becoming much more hospitable. A prime example is Scandinavia.

Nordic vintners are increasingly convinced that they can develop thriving commercial operations in what used to be places that are too cold for successful wine-making.

Denmark now has 90 commercial vineyards, up from just two 15 years ago. Forty vineyards have sprung up in Sweden. About a dozen vineyards are now operating as far north as Norway.

Many of these Nordic vineyards are in the startup stage and are tiny compared with the established wineries of Europe. Europe has 10 million acres of vineyards, which is enough to cover almost the entire country of Denmark. At the moment, there are only about 1,000 acres of vineyards in Denmark and Sweden.

But, looking forward, Scandinavia’s climate is forecast to be more like northern France, as regional temperatures climb as much as 10 degrees Fahrenheit. Over the past decade, warming has produced milder winters, a longer growing season, and even a small but rising number of award-winning Scandinavian wines.

Meanwhile, traditional wine-growing regions are also dealing with climate change. Winemakers in France, for example, are experimenting with grapes from warmer countries like Tunisia to see if they can retain the tastes and yields that are the basis of a multibillion-dollar wine industry. Spanish and Italian winemakers are planting grapes higher up on mountainsides or on shaded north-facing slopes to preserve the quality of their wine.

Climate Change And Insurance

May 17, 2019 By EarthWise Leave a Comment

While there are still some people who remain dubious about the reality of climate change, insurance companies are not among them. And, in fact, insurers are warning that climate change could make coverage for ordinary people unaffordable.

Munich Reinsurance, the world’s largest reinsurance firm, blamed global warming for $24 billion in losses from California’s recent wildfires. Such costs could soon be widely felt as premium rises are already under discussion with insurance companies having clients in vulnerable parts of the state.

With the risk from wildfires, flooding, storms and hail increasing, the only sustainable option for the insurance industry is to adjust risk prices accordingly. Ultimately, this may become a social issue. Affordability of insurance is critical because if rates go up too much, many people on low and average incomes in some regions may no longer be able to buy insurance.

The great majority of California’s 20 worst forest fires since the 1930’s has occurred since the year 2000 driven by abnormally high summer temperatures and persistent drought. The reinsurance giant analyzed decades of data with climate models and concluded that the fires are likely driven by climate change.

It isn’t just wildfires. Insurance premiums are also being adjusted in regions facing an increased threat from severe convective storms whose energy and severity are driven by global warming. These include parts of Germany, Austria, France, southwest Italy, and the U.S. Midwest.

Linking extreme weather events to climate change is a bit like attributing the performance of a steroid-using athlete to drug use. The connections are clearer in patterns than in individual disasters. But the pattern these days is pretty clear.
