Electric cars: Boom or bust?

September 25, 2024 By EarthWise Leave a Comment

Media coverage of electric cars in this country is pretty confusing. Are electric cars taking over or has the EV bubble burst?

EVs currently represent about 8% of the US new car market. But they continue to face some relatively unique headwinds in this country. A very powerful and influential oil industry makes sure that anti-EV stories occupy center stage in the media. Traditional car dealers don’t want to sell EVs because they don’t make much money from parts and service. And EVs often find themselves tangled up in American politics.

Meanwhile, the rest of the world tells a very different story. Globally, EVs constitute 20% of new car sales, but in some places, they are doing much better than that.

So far this year, almost 87% of new car sales in Norway are electric and in August, the figure was 94%. Norway has some incentives in place for EV owners, but the fact that nearly all new cars on the road are electric is far more than the result of incentives.

One might argue that Norway, a country with only 5 million people, faces a much easier task of transitioning to EVs. But how about China with its 1.4 billion people? In July, plug-in vehicles in China were 51% of new auto sales. And the numbers continue to rise.

There are plenty of articles out there explaining why electric cars just can’t meet people’s needs, have insurmountable problems, and how having too many of them would collapse electric grids and otherwise wreak havoc with society. Apparently, the Norwegians and Chinese, among a growing number of other countries, haven’t gotten the memo.

Dangers Of Melting Glaciers | Earth Wise

March 31, 2023 By EarthWise Leave a Comment

Some of most dramatic evidence that the Earth’s climate is warming is the retreat and even disappearance of mountain glaciers around the world. 2022 was the 35th year in a row that glaciers tracked by the World Glacier Monitoring Service lost rather than gained ice. Glaciers gain mass through snowfall and lose mass through melting and sublimation (water evaporating directly from solid ice.) Some glaciers that terminate in lakes or the ocean lose mass through iceberg calving.

In the warming climate, glaciers retreat and meltwater collects at the front of the glacier forming a lake. Such lakes can suddenly burst and create a fast-flowing Glacier Lake Outburst Flood that can spread over a large distance from the original site – in some cases over 70 miles. These floods can damage property, infrastructure, and agricultural land and can also be deadly.

The number of glacial lakes has grown rapidly since 1990 as a result of climate change. According to research by an international team of scientists led by Newcastle University in the UK, the number of people living in glacial lake catchments has increased significantly.

According to the study, 15 million people live within 30 miles of a glacial lake. The highest danger is in High Mountain Asia – which encompasses the Tibetan Plateau. That area, which spans from Kyrgyzstan to parts of China, has 9.3 million people potentially at risk. India and Pakistan have around 5 million exposed people.

Detailed analysis shows that it is not the areas with the largest number or most rapidly growing lakes that are most dangerous. It is the number of people in proximity to the lakes and their ability to cope with potential floods.

A Bad Year For California Rice | Earth Wise

November 2, 2022 By EarthWise Leave a Comment

Rice production is the third largest cereal crop in the United States after corn and wheat. Four regions in the country produce almost the entire U.S. rice crop: the Arkansas Grand Prairie, the Mississippi Delta, the Gulf Coast, and the Sacramento Valley in California. Arkansas is the largest producer of rice in the country by far, but California ranks second.

A combination of drought and water shortages in the Sacramento Valley has taken a major toll on the California rice crop. This year, rice growers have only planted half as much grain as usual. The changes in rice plantings in California are so substantial that they are easily visible from space.

In Colusa and Glenn counties, rice acreage this year dropped by 84 and 75 percent respectively, compared to 2021. Farther to the east, in Butte Country, rice acreage was down by 17%. The change was smaller there because farmers in that county had more groundwater to tap into.

According to the USDA, the California rice crop will be reduced by 38% this year, making it the smallest rice crop in the state since 1977. California mostly grows short- and medium-grained rice, which is used in dishes like sushi, paella, and risotto. Arkansas and other states produce most of the long-grain rice such as basmati and jasmine rice.

In late September, there was a burst of rain, which offered some short-term relief for farmers. However, it will take much more wet weather to ease the ongoing drought conditions. As of the end of September, over 40% of California remained in extreme drought and 17% was in exceptional drought.
