The significance of the new East Asian fossil human Penghu 1

A new early human fossil has been reported, recovered from the seabed near Taiwan. We are calling it Penghu 1. Simply put, it is the lower right jaw of a hominid (hominine) that most resembles either a form of Homo erectus or Archaic Homo sapiens (kin to, but not, Neanderthal). Teeth are fairly useful for…

More on the Great Blizzard of 2015

The Blizzard continues. The center of the low pressure system moved to the northeast more than expected, so the maximum snowfall amounts have also moved deeper into New England, and it the storm may end up dropping the largest amounts Downeast, in Maine, rather than around New York and southern New England. Nonetheless maximum snow…

Glacial melt could change chemistry and food web in world’s oceans

Along with increasing sea levels, melting glaciers are putting something else into the world’s oceans — a huge load of organic carbon that has the potential to change marine chemistry and ecosystems, says a newly published study by a team of mostly Alaska scientists. (…) The accelerated melt of glaciers gets attention because of its […]

Oceans face higher acidity levels as more man-made CO2 gets absorbed

Just about 5 million tons of carbon dioxide (CO2) is dumped into the atmosphere every hour from the burning of fossil fuels mostly for transportation, electrical generation, industry and heating. This is the fastest rate of CO2 generation that the earth has experienced in millions of years. It’s been estimated that about a quarter of […]

Another Sign North Korea is Trying to Develop a Nuclear Missile Submarine

North Korea is attempting to put nuclear weapons to sea, according to a longtime regime watcher.Joseph Bermudez—an expert on North Korean weapons—believes the evidence is commercial satellite imagery showing a submarine with possibly two vertical launch tubes. The regime also appears to have constructed a test stand for launching sea-based ballistic missiles. link.

The Great Blizzard of 2015: Fair to say it is AGW enhanced.

About 20 million people are currently under a blizzard warning, and double that under a winter weather advisory, for a storm moving into the Northeast today and tomorrow, with snow falling though Wednesday. Thousands of flights have been cancelled. Wind will be at tropical storm force, and occasionally, hurricane force, and coastal flooding is expected…

Experts: include ocean acidification in climate change negotiations

Monaco – Actions to mitigate and adapt to ocean acidification in a future global climate deal could make the agreement stronger and facilitate its implementation. That was one of the conclusions from last week’s international workshop on ocean acidification organised by the IAEA in Monaco. Scientists aren’t alone in raising the threat from ocean acidification; […]

Acid in seas and mudflats threatens to wipe out local shellfish populations

56 million years ago, a massive release of carbon dioxide into the atmosphere and oceans caused a monumental shift in the climate, increasing the earth’s surface temperature by 11 degrees. Meanwhile, a rapid chemical change in the ocean occurred as the gas and water formed carbonic acid, eventually causing the extinction of all of the […]
