We Are The 95%! -IPCC

So just what does the latest suppositional proclamation that the IPCC is peddling, actually mean?  That being, that they are “95% certain” that humans are causing ‘climate change’.  James Corbett breaks down the latest effort to make science appear to be a popularity contest.  Just, “how sure are these scientists?  They say 95% certain, and in science 95% is pretty darn certain….” -CNN repeater

In recent days, you’ve probably heard ad nauseum that the UN’s new IPCC report claims that it is “95% certain” that humans are causing climate change.

95% is a very specific number. So where does it come from?

The IPCC uses a “likelihood scale” that assigns percentages to various phrases, ranging from “exceptionally unlikely” (0-1% probability) to “virtually certain” (99-100% probability). This sounds like it is based on a precise scientific measurement or well-defined statistical process, but when it comes to deciding how likely it is that climate change is manmade, this is in fact a subjective decision that is made by the report’s authors.

IPCC 95% Certain That Humans Are Dominant Cause Of Global Warming

So what will the Greedy Lying Bastards (that would be the climate change deniers) say about this? From BBC News:

A UN panel has released part one of its six-yearly update on the state of the Earth’s climate. The much-anticipated report by the Intergovernmental Panel on Climate Change (IPCC) says that with 95% certainty, humans are the dominant cause of global warming since the 1950s. The BBC News website’s science editor Paul Rincon breaks down some of the document’s key findings.

Part one of the IPCC’s fifth assessment report (AR5) on the Earth’s climate opens with the message that we are seeing changes in the climate system unprecedented in records spanning hundreds of years.

With this scene-setting out of the way, the report says the period from 1983-2012 in the Northern Hemisphere was likely the warmest 30-year period of the last 1,400 years. Each of the last three decades has got successively warmer, and these decades have all been warmer than any of the preceding decades since 1850.

Climate Panel Claims ‘Near Certainty’ of Man-Made Global Warming

The results are in and they aren’t good, for anyone, climate deniers especially. The New York Times reports on the IPCC‘s dour assessment of climate change:

An international panel of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could conceivably rise by more than three feet by the end of the century if emissions continue at a runaway pace.

The scientists, whose findings are reported in a draft summary of the next big United Nations climate report, largely dismiss a recent slowdown in the pace of warming, which is often cited by climate change doubters, attributing it most likely to short-term factors.

The report emphasizes that the basic facts about future climate change are more established than ever, justifying the rise in global concern. It also reiterates that the consequences of escalating emissions are likely to be profound.

NOAA: ’2012 Was an Active [Hurricane] year, But Not Exceptionally So

Via WattsUpWithThat.com

Busy 2012 hurricane season continues decades-long high activity era in the Atlantic

Four U.S. land-falling storms include devastating Sandy and Isaac

November 30 marks the end of the 2012 Atlantic Hurricane season, one that produced 19 named storms, of which 10 became hurricanes and one became a major hurricane. The number of named storms is well above the average of 12. The number of hurricanes is also above the average of six, but the number of major hurricanes is below the average of three.

Based on the combined number, intensity, and duration of all tropical storms and hurricanes, NOAA classifies the season as above-normal. 2012 was an active year, but not exceptionally so as there were 10 busier years in the last three decades.

This season marks the second consecutive year that the mid-Atlantic and Northeast suffered devastating impacts from a named storm. Sandy, and Irene last year, caused fatalities, injuries, and tremendous destruction from coastal storm surge, heavy rainfall, inland flooding, and wind.

Ask Randall: Climate Change

Independent Scholar Randall Carlson takes time to answer a question from a facebook fan regarding climate change.

Elizabeth writes, “Randall Carlson, can you look at his data and still maintain our recent temperature increases are just an anomaly?”  Linking to the controversial New York Times article, “The Conversion of a Climate Change Skeptic”

Hello Elizabeth.

I am responding to the question you raised regarding my opinion of the New York Times article on the recent work of physicist Richard Muller on climate change.  You asked: “Can you look at his data and still maintain our recent temperature increases are just an anomaly?”  My first impression is that you have not understood my position on this issue.  To clarify that position, I would state that I do not consider the present warming of the climate to be an anomaly, rather I believe that the present scale and rate of climate change is well within the range of natural variability, and is, therefore, not anomalous at all.  This opinion is based upon nearly three decades of in-depth study into the matter of climate change over multiple time scales.  What has become apparent, from an ever growing body of evidence, from many diverse sources, is that the climate of the past has constantly changed, with a range of variability far exceeding anything experienced within recent history, say for example, since the inception of the Industrial Revolution.… Read the rest

On the Credibility of Climate Research, Part II: Towards Rebuilding Trust

Climate ChangeBy Judith Curry, Georgia Institute of Technology

I am trying something new, a blogospheric experiment, if you will.  I have been a fairly active participant in the blogosphere since 2006, and recently posted two essays on climategate, one at climateaudit.org and the other at climateprogress.org. Both essays were subsequently picked up by other blogs, and the diversity of opinions expressed at the different blogs was quite interesting.  Hence I am distributing this essay to a number of different blogs simultaneously with the hope of demonstrating the collective power of the blogosphere to generate ideas and debate them.  I look forward to a stimulating discussion on this important topic.

Losing the Public’s Trust

Climategate has now become broadened in scope to extend beyond the CRU emails to include glaciergate and a host of other issues associated with the IPCC. In responding to climategate, the climate research establishment has appealed to its own authority and failed to understand that climategate is primarily a crisis of trust.… Read the rest
