In early December I wrote a post called "2014 will not be the warmest year on record, but global warming is still real." The very first thing I said in that post is that I was going out on a limb. I also discussed whether or not one year mattered, and I discussed the nature of the phrase "X is the Yth warmest year on record," going into details on what "the record" is and how we measure this. I want to reiterate something very important that I mentioned then. Here, we are talking about a combination of measurements from the sea surface and the air just over the land (about where your head is when you are walking around). Changes in this surface measurement over time reflect less than about 5% of the overall changes in temperature experienced by the Earth because of the addition of greenhouse gasses to the atmosphere (or reduction of "sinks" of those gasses, or of heat) by human activity. Most of the additional heat goes into the ocean. The reason I was conservative in my earlier … [Read more...] about 2014 may be the warmest year on record

Roughly ten thousand years ago, raging glacial meltwaters created the broad valley of the Upper Mississippi River that we know today. They also helped form one of the river’s most famous and significant landmarks, known in Dakota as He Mni Caŋ (Hill Water Wood) and in English as Barn Bluff. As the last ice age came to an end, the glaciers melted. Glacial Lake Agassiz was formed from melt water. From Minnesota, the lake extended far into Canada, was more than 600 feet deep, and covered an area larger than the present-day five Great Lakes combined. As melting continued, the enormous body of water broke free and, joined by other melt waters began racing south and east through central Minnesota as glacial River Warren. This river, and others like it during the Pleistocene, carved the path of the present-day Minnesota River, merging it with another smaller river, the Mississippi. Over time, the combined water mass eventually carved the broad valley of the Mississippi. As the … [Read more...] about Barn Bluff has stood over thousands of years of history in the Red Wing area
Health mental health schizophrenia Changes to the human brain as we evolved may have led to the development of bipolar disorder and schizophrenia, according to a study. Scientists believe that some mental illnesses could be a side effect of how quickly our brains expanded and developed in the relatively recent evolutionary history of the past few hundred thousand years. Similarly, certain lower back, knee and foot problems are likely caused by our bodies quickly changing to walk upright. Past studies have linked the risk of developing bipolar disorder and schizophrenia to a gene which helps to transport calcium—which is important for neural activity—in the brain. But scientists don’t yet know if the mutation can trigger these neuropsychiatric diseases, the authors of a study published in the American Journal of Human Genetics wrote.

Visit The Boston Globe Share on Twitter Share on Facebook Comment on this Scroll to top of page By Christopher Mooney The Washington Post July 12, 2018 Thirteen thousand years ago, an ice age was ending, the Earth was warming, the oceans were rising. Then something strange happened — the Northern Hemisphere suddenly became much colder, and stayed that way for more than a thousand years.For some time, scientists have been debating how this major climatic event — called the ‘‘Younger Dryas’’ — happened. The question has grown more urgent: Its answer may involve the kind of fast-moving climate event that could occur again.This week, a scientific team made a new claim to having found that answer. On the basis of measurements taken off the northern coasts of Alaska and Canada in the Beaufort Sea, the scientists say they detected the signature of a huge glacial flood event that occurred around the same time.

A man convicted in the 2016 death of a Roanoke woman was given a 10-year prison sentence Friday with all but one year of that time suspended.James Kevin O’Dell, 40, of Collinsville previously pleaded no contest to voluntary manslaughter in Roanoke Circuit Court.O’Dell initially was charged with second-degree murder in the death of Erin Nicole Marley, his girlfriend of nine months, but that count was reduced as a result of his plea.Prosecutors said at his March 2 plea hearing that the circumstances of the case made it difficult to prove the exact cause of Marley’s demise, and they also agreed not to seek more than a three-year prison sentence.At Friday’s hearing, Judge Chris Clemens said that although sentencing guidelines called for a maximum punishment of six months behind bars, he intended to exceed that limit with an active term of one year.Nevertheless, O’Dell has been incarcerated since April 2017 and so has already served the time he was … [Read more...] about Voluntary manslaughter plea in Roanoke woman’s death brings boyfriend 1-year jail term
