I just heard an interview on WCAI’s show The Takeaway with Richard Seager of the Lamont Doherty Earth Observatory of Columbia University in Palisades, New York. He was asked the common, pointed question: “well, can you blame the recent weather on global warming?” First of all, does this journalist need a reminder that global warming is a completely different phenomenon than climate change? Have we not progressed far enough to understand the difference in this fundamental terminology? I am frustrated but not really surprised at the number of times I’ve heard this in the news media. What I’d really like to hear is ‘climate change’ not global warming!
Climate change is still a debatable term amongst climate scientists and one that deserves further clarification. This past spring I took a seminar that discussed publications and new research topics in the field of climate change. One of the first tasks we tackled in our discussion(s) was to define both weather and climate. Then we went into more depth to analyze the differences between the two terms. From a science viewpoint, it is much more complex than we realize. However, to keep things simple from hereon out, I will try to define and utilize these terms relative to human time scale.
For now, let’s consider the topic of climate shifts, change or fluctuations and not global warming please. It’s so ‘1980’s and I’d like to believe we have moved past this problem. The hole in the ozone layer, global warming and greenhouse gases may still be a problem on a shorter time scale, but changes in global climate patterns are extremely significant and not restricted to polar regions.
For more information about what’s happening (from Seager’s perspective) in Europe here’s some reading.
Iron fertilization is a controversial topic within the realm of ocean science.
General science has been receiving some interesting news in the past week. I first heard a watered down summary of this report on npr that stated to the effect that scientists are still respected… but… the yahoo story seems to portray more. I was frustrated by the lack of clarity or should I say, ‘real science’ so I decided to source the information on the Pew Research Center’s webpage. I actually received a recent Science magazine publication that discussed this concept of measuring the results of science and how to quantify the outcomes or benefits of funding allocation.
In keeping with the distilled npr version that I heard, the Pew poll shows that scientists rank highly (among doctor’s, engineers, military and teachers) in the public’s perception of those that contribute to society. That is good news, but not entirely surprising. From a general public standpoint (that is, if I were not considering myself a scientist) we regard scientists among doctors and those that we look to for guidance, judgement and critical facts to make decisions that impact a great many lives. So, I am in agreement with the poll results and generally think it reflects society.
