This is both my personal learning project and my contribution in the struggle to confront the ongoing Republican/ libertarian assault on rational science and constructive learning, as manifested in their malicious strategic Attacks on Science ~ A collection of articles, scientific resources, plus my own essays and indepth critique of various presentations from unidirectional-skeptics ~ Hopefully a resource for the busy, yet discerning, student who's concerned about the health of our Earth
". . . I think there’s a lot of misconception on this issue and I see no evidence that Judith is thinking clearly with respect to her claims about the IPCC. Much of the debate has centered around semantics and definitions, so I want to start off with what many people take as “sides” to the debate, particularly when saying things like “the IPCC view” or identifying what a “skeptic” means. Much of the confusion is centered directly on how the scientific community comes to acquire knowledge on a specific topic, or how knowledge of global climate change has evolved.
The fourth assessment report of the IPCC consisted of three volumes of work, on the scale of ~1000 pages each, with the goal of summarizing research in the areas of the physical science, impacts, and policy of climate change. The AR4 does not represent original research, and so to begin with what Judith and other commenter’s refer to as the “IPCC view” is in reality the aggregate work done by the community in whatever sub-topic is being discussed, expressed as a summary of the “balance of evidence.”
This is a guest post by James Lawrence Powell.* Polls show that many members of the public believe that scientists substantially disagree about human-caused global warming. The gold standard of science is the peer-reviewed literature. If there is disagreement among scientists, based not on opinion…
Climate Change Line of Evidence - videos: Part I
Filed under:
— group @ 9 October 2012
The US National Research Council has been doing a lot recently to expand background knowledge of the climate system and of climate change. In tandem with a new report discussing strategies for advancing climate modeling, they have put up a an introductory web site on climate models (including some interviews with some actual climate modelers).
More comprehensively, they have helped put together a series of videos discussing everything from the definition of climate to attribution of climate changes and future projections.
The series is in seven parts, viewable here.
There are additional resources here.
Trying to inject distrust, simply by making claims, never appreciating or sharing that what we are talking about is dedicated people - researchers and scientists and support staff going out in the field to conducting studies and doing the research and trying to be as accurate as possible in recording their observations. No perfect at/in any part of this endeavor {like every other human enterprise} - but it works and it works well and they have learned a lot that does not deserve the contrived ridicule the "Free corporate Marketers" have orchestrated.
There is a base dishonesty about folks like Curry and commenters at her website - when they are basing all their thinking on an assumption that the science has been inferior. They don't provide actual specifics regarding ~ our actual factual world full of knowledge and experience that climatologists and related field of researcher have been accumulated ~ but they sure do continue believing themselves.
I think we've reach the point it's obvious that this is all about desperately clinging to one's fictitious world view (Free Market, no Anthropogenic Global Warming, no need to change a thing about the way we lead our business and lives.) and not about the state of our knowledge. Fear, fear and anger overriding objectivity and reason. OK I'll get off my soapbox and invite you to listen to some very smart hard working scientists tell their own story:
Glen Gerberg Weather and Climate Summit
The Weather and Climate Summit was established in 1985 to bring together television weathercasters and meteorologists from top U.S. and Canadian markets with leading scientists and researchers. This summit allows for dynamic and frequent interchange between the media and scientists in order to foster improved communication and collaboration between these diverse professions.
The Weather and Climate Summit enables television meteorologists to learn more about upcoming technologies and research findings that will lead to improved public awareness. The Weather and Climate Summit also helps the attendees and scientists understand how each one operates, produces information, conducts research and communicates. The ultimate outcome of this summit is the establishment of improved media-scientist relationships that fosters continued dialogue for improved scientific communication to the public.Goal of Summit Participants
- To learn about advanced technologies that can help improve weather forecasting and warning dissemination;
- To understand the latest on the state of the climate and climate science research;
- To better understand how extreme weather and climate change may impact their viewers;
- Foster improved relationships with the speakers, scientists and subject matter experts.
Impact of declining Arctic sea ice on winter snowfall
http://www.pnas.org/content/109/11/4074
Abstract:
While the Arctic region has been warming strongly in recent decades, anomalously large snowfall in recent winters has affected large parts of North America, Europe, and east Asia.
Here we demonstrate that the decrease in autumn Arctic sea ice area is linked to changes in the winter Northern Hemisphere atmospheric circulation that have some resemblance to the negative phase of the winter Arctic oscillation.
However, the atmospheric circulation change linked to the reduction of sea ice shows much broader meridional meanders in midlatitudes and clearly different interannual variability than the classical Arctic oscillation.
This circulation change results in more frequent episodes of blocking patterns that lead to increased cold surges over large parts of northern continents.
Moreover, the increase in atmospheric water vapor content in the Arctic region during late autumn and winter driven locally by the reduction of sea ice provides enhanced moisture sources, supporting increased heavy snowfall in Europe during early winter and the northeastern and midwestern United States during winter. We conclude that the recent decline of Arctic sea ice has played a critical role in recent cold and snowy winters.Also see the story at: http://gtresearchnews.gatech.edu/arctic-ice-decline/
Dr. Jennifer Francis of Rutger’s Institute of Marine and Coastal Sciences is featured in my sea ice wrap video, which should be out early in the week.
Here is a lecture she gave in January of 2012. Longish, but worth dipping into, as she summarizes some of the most recent research in regard to the effects of shrinking arctic ice on weather and climate in the temperate latitudes – the so-called “arctic paradox” so beloved by Fox News – “if there’s global warming, why are we having this record snow storm?”.
~ ~ ~ ~ ~ ~ ~What she told me in a recent interview was that the sea ice record is not something that we just pay attention to in September – there will, in fact, be reverberations that will make fall and winter “very interesting” around the globe.
Heat waves. Drought. Flooding. Cold spells. Wildfires. The climate system is changing before our very eyes, and there is no more glaring proof than the record-shattering loss of Arctic sea ice this summer.
The National Snow and Ice Data Center announced Wednesday that the sea ice covering the Arctic Ocean has smashed the previous record minimum extent set in 2007 by a staggering 18 percent. The impacts of rising temperatures and melting ice extend beyond the far north to us in the United States, as we are poised to feel the weather-related backlash.
The ice cover, only half of what it was only a few decades ago, is a stunning visual demonstration of the effects that increasing greenhouse gases, and resulting warming of the Earth, are having on the climate system...
