Sea ice average for March is the metric used to compare to previous winters

The average sea ice cover at the end of March is the metric used to compare ‘winter’ ice to previous years or decades, not the single-day date of ‘most’ ice. This year, March ended with 14.6 mkm2 of sea ice, most of which (but not all) is critical polar bear habitat. Ice charts showing this are below.

But note that ice over Hudson Bay, which is an almost-enclosed sea used by thousands of polar bears at this time of year, tends to continue to thicken from March into May: these two charts for 2020 show medium green becoming dark green, indicating ice >1.2 m thick, even as some areas of open water appear.

Climate-Change ‘Solutions’ That Are Worse Than The Problem

If you can afford a Tesla, you probably find it hard to imagine that there are some 3.5 billion people on Earth who have no reasonably reliable access to electricity.

Even less obvious may be the way rich countries’ pursuit of carbon neutrality at almost any cost limits economic opportunities for the world’s poor and poses serious geopolitical risks to the West. [bold, links added]

Anyone on an investment committee has likely spent untold amounts of time discussing ways to mitigate the impact of climate change, but they’ve likely never heard anyone state one simple and incontrovertible fact: The widespread exploration and production of fossil fuels that started in Titusville, Pa., not quite 170 years ago has done more to benefit the lives of ordinary people than any other technological advance in history.

Before fossil fuels, people relied on burning biomass, such as timber or manure, which was a far dirtier and much less efficient source of energy.

Fossil fuels let people heat their homes in the winter, reducing the risk of death from exposure. Fossil-fuel-based fertilizers greatly increased crop yields, reducing starvation and malnutrition.

Before the advent of the automobile, the ability for many people to venture far from their hometown was an unfathomable dream.

Oil- and coal-burning transportation opened up access to education, commerce, professional opportunities, and vital services such as medicine.

There has been, and remains, a strong correlation between the use of fossil fuels and life expectancy.
