There has been a 4–6% decline in Arctic Sea Ice over the satellite era (see graphs below). Antarctic sea ice increased almost the same amount in 2016–2018, but it is now down slightly (1–3%) as well. It is hard to be sure that this change is significant as the longer term records required to be certain do not exist.

The average American ate some 220 pounds of red meat and poultry in 2018, according to the US Department of Agriculture, surpassing a record set in 2004.

But some politicians have joined anti-meat and climate change activists in a massive effort to restructure the American diet – and to ensure … and mandate … that the rest of the world will be stuck with a mostly plant-based diet.

The New Jersey legislature came very close to enacting a law, S. 2173, that would end religious or philosophical exemptions parents use to opt-out of vaccinating their children who attend state schools.

Ann Jones tried everything short of surgery for her chronic migraines, which have plagued her since she was a child.

“They’ve actually gotten worse in my old age,” says Jones, who is 70 years old and lives in Tucson, Ariz.

Scientists from Moscow Institute for Physics and Technology, Space Research Institute of the Russian Academy of Sciences (IKI), and Pulkovo Observatory discovered a unique neutron star, the magnetic field of which is apparent only when the star is seen under a certain angle relative to the observer.

Lithium batteries have high energy storage capacity, but sometimes they have unexpected failures and can even cause a fire.

A team of scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) demonstrated for the first time how dendrites and whiskers — destructive, crystalline structures formed by lithium ions come into existence inside a battery.

“While the president rages, the world melts,” keened The Washington Post in an editorial over the weekend.

As President Trump spent another week rage-tweeting, the world continued to warm, and the consequences became ever-clearer — and more alarming.

Estimates used by climate scientists to predict the rate at which the world’s ice sheets will melt are still uncertain despite advancements in technology, new research shows.

These ice sheet estimates feed directly into projections of sea-level rise resulting from climate change.

Four reconstructions from the central and western High Arctic reveal July temperatures were about 1-2°C warmer than today during most of the 1st millennium and Medieval period (Tamo and Gajewski, 2019).

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand.

Lyme disease and human babesiosis are the most common tick-borne zoonoses in the Temperate Zone of North America. The number of infected patients has continued to rise globally, and these zoonoses pose a major healthcare threat. A new study provides fresh insights to better inform health care providers.

Artist’s representation of how Venus may have appeared with water — NASA

Despite Mercury being the closest to the Sun, Venus is the hottest planet in our Solar System due to the transformation that changed its atmosphere radically somewhere in the past. The average surface temperature of 462° C (864° F) of Venus can melt Lead.

The Big Oil-Big Biofuel wars rage on. From my perch, ethanol, biodiesel and “advanced biofuels” make about zero energy, economic or environmental sense.

They make little political sense either until you recognize that politics is largely driven by crony-capitalism, campaign contributions, and vote hustling.
