AAAS Weighs in on Attacks on Climate Scientists

with 4 comments

American Association for the Advancement of Science (AAAS) issued the following statement dated June 28, 2011:

We are deeply concerned by the extent and nature of personal attacks on climate scientists. Reports of harassment, death threats, and legal challenges have created a hostile environment that inhibits the free exchange of scientific findings and ideas and makes it difficult for factual information and scientific analyses to reach policymakers and the public. This both impedes the progress of science and interferes with the application of science to the solution of global problems.

Time for Accountability

with 14 comments

(Reposted from The Conversation)

The overwhelming scientific evidence tells us that human greenhouse gas emissions are resulting in climate changes that cannot be explained by natural causes. Climate change is real, we are causing it, and it is happening right now. Like it or not, humanity is facing a problem that is unparalleled in its scale and complexity. The magnitude of the problem was given a chilling focus in the most recent report of the International Energy Agency, which their chief economist characterized as the “worst news on emissions.” Limiting global warming to 2C is now beginning to look like a nearly insurmountable challenge.

Review of Generation Us: The Challenge of Global Warming by Dr. Andrew Weaver

Generation Us: The Challenge of Global Warming by Dr. Andrew Weaver

Climate change is the most important issue facing all of us today and tomorrow, therefore it is a topic that we must all try to understand if we are to make educated decisions about our future and the future of the generations that follow. Climate science is complex because it encompasses a wide array of various fields so even a scientist can find it a Herculean task to try to understand. So where does that leave the rest of us who wish to become educated?

Fortunately, Dr. Andrew Weaver has delivered this wonderful little book designed for “climate beginners” that, in just over 100 easy-to-read pages, leaves the reader quite educated about why scientists know humans are causing the planet to warm and the various choices that society must consider in order to deal with the problem.

Dr. Hansen’s Comment to the Naysayers

with 4 comments

Dr. James Hansen recently toured New Zealand to provide climate talks to various stakeholders and to urge Prime Minister Key of New Zealand to “leave the massive deposits of lignite coal in the ground, instead developing its natural bounty of renewable energies and energy efficiency.” Dr. Hansen writes about the trip, and in a noteworthy footnote, makes the following comment to those that send him negative mail.

Climate Change: It’s the Humans

with 10 comments

On May 26 I offered an online presentation about human’s role in global warming to the American Institute of Chemical Engineers (Virtual Local Section).

Abstract: Warming of the climate system in the modern era is unequivocal and multiple lines of evidence point to human activity, primarily the emission of carbon dioxide, as the cause of most of this warming. The author will illustrate the evidence for planetary warming, highlight the human fingerprints of greenhouse warming, and show why many of the skeptic arguments are either false or highly misleading.

I was asked to present in response to April’s speaker, Dr. Arvid Pasto, who believes that human-caused global warming is a scam. (One can see a January 2011 presentation by Dr. Pasto here: http://files.meetup.com/1666746/AGW_Hoax_General.pdf and his April AIChE presentation here: https://aiche.webex.com/mw0306lc/mywebex/nbrDownload.do?siteurl=aiche)

Dr. Pasto’s April presentation was riddled with mistakes and many of his sources were typical deniers such as: Jo Nova, Will Happer, Anthony Watts, etc. It would have been very easy to go through each slide and point out the mistakes but I chose the high road instead and focused on the science (why reinforce myths by repeating many of them?) I do correct a few of his “mistakes” toward the end of the presentation.

You can view my slideshow in .PDF format without the audio/video.  (There were some technical difficulties with the live stream that did not allow Webex to save the audio and video.  Ugh!)
