Anthropogenic Climate Change

by Andrew

Last night, a reader’s comment caused to me provide an explanation of the greenhouse effect and how this shows us that human activity is primarily driving climate change. I was asked to repost that comment here.

The scientific process is simple: state a hypothesis, test it, and analyze the results. There are many hypotheses involved in climate change, but let’s start with the one most fundamental to human causation. We know that so-called greenhouse gases trap heat in the Earth’s atmosphere; if they didn’t, the Earth would resemble Mars and life would probably never have evolved (or at least, never gotten beyond single-celled extremophiles living in volcanic vents). The greenhouse effect is the only reason I’m sitting here typing this response; it’s supposed to occur.

But let’s prove that this is true. The Vostok ice core (perhaps the most famous of the ice cores drilled so far) gives us measures of temperature and carbon dioxide concentration for the past 420,000 years, a period twice as long as the age of our species and involving multiple major fluctuations in both metrics (natural climate change). In that period, the highest concentration of carbon dioxide occurred about 320,000 years ago, when it reached 300 parts per million (ppm). This was also one of the hottest period in the record. Every fluctuation in carbon dioxide levels is matched by a fluctuation in temperature; both go up at the same time, and both go down at the same time. read more »

Hyper-local Birds: Mourning Dove

by PaulM

Mourning Dove

This bird or a close cousin and others like it contribute to the morning music in and around the South Common. With its many trees and bushes, the Common is an aviary of sorts, especially at this time of year. I don’t know the bird types well enough to list them here, but I’ve seen at least 20 different kinds of birds on the Common. In the early morning they pick at the ground and swoop down by the pool to get crumbs from the kids’ snacks. The mourning doves make the same “hoo-hoo” sound I heard from them on the island of St. Lucia, where my family vacationed in winters past. The doves were a familiar sight in that tropical landscape. Here, I often see a solitary dove perched atop a telephone pole. The call is unmistakable. Beyond the sparrows, robins, crows, and blue jays that I know by sight, I’d be interested to know about the other urban birds if some of our readers can name the local flying creatures. I haven’t seen them lately, but I’ve seen seagulls grazing on the sports field on the floor of the Common.  (Photo: Courtesy of Gainesville State College in Georgia website)

Hyper-local Weather in Lowell

by Tony

The weather is unquestionably the top story this week…and UMass Lowell’s Weather Center provides the best Lowell weather forecast around.  The University’s Department of Environmental Earth, and Atmospheric Sciences maintains the website.

It is one thing to listen or watch  Boston forecasters but it is a completely different experience to get weather specific to Lowell…and the Weather Center posts some really cool bits of information:  Like the current temperature, Humidity, and Wind speed in Lowell updated every five minutes.  You’ve got to love that…Lowell’s weather conditions updated every fine minutes!

The University gathers this information from a Center located on the roof of Ball Hall on North Campus. And of course, there is a long range forecast for the Merrimack Valley.

Check it out…Its fun to follow the hyper-local weather

He says President Obama is facing “a Lincoln moment” and has to come up with a response that can pull the nation together again.
