Is the IPCC's science the gold standard or questionnable?

Environmental Economics

For several commentators, the panel’s continued inclusion of the IPCC report as a source of information was an issue. 19 panel meeting, saying he thinks the panel shouldn’t use data from the IPCC report. He said he had been one of the IPCC report’s expert reviewers and that the report’s sea level rise acceleration scenarios aren’t credible. However, he said the draft makes the assumption that the IPCC is “the gold standard” for sea level rise information.

"The IPCC treatment of the total economic impact of climate change"

Environmental Economics

  Although the estimates may not change that much, the degree to which the IPCC is "certain" has increased over time (and justifies some additional rhetoric). Everyone would agree I am sure that the IPCC should be objective and base their summaries on the scientific facts.  The real issue is what the IPCC and governments should do in light of these "not surprising" results?

The 10 things you need to know from the new IPCC climate report

Green (Living) Review

The latest IPCC report is out, and the news is not happy. The chair of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, called the report the “strongest, most robust and most comprehensive” to come out of the IPCC, which has been tracking climate change since 1988. As we explained last week , you may be experiencing déjà vu — that’s because there have been three IPCC reports released since September 2013. climate change green living IPCC

The Entire IPCC Report in 19 Illustrated Haiku

Sightline Daily

Reports released by the International Panel on Climate Change (IPCC) can be daunting, even for science and policy insiders. Housebound with a rotten cold one recent weekend, Greg Johnson found himself paring his key takeaways from the IPCC report into haiku. He never intended to share these “IPCC” poems. The full Physical Science Assessment, the first installment of the Fifth Assessment Report (pdf), released in manuscript form earlier this year, is over 2,000 pages long.

The Past and Future of the IPCC

McKibben warns (and rightfully so) that the IPCC documents “almost certainly underestimates the actual severity of” climate change and the situation we''re in. Another problem is that the IPCC’s reports are based on science that is already several years old.

The IPCC was quite diplomatic in its discussion, saying “Biofuels have direct, fuel‐cycle GHG emissions that are typically 30–90% lower than those for gasoline or diesel fuels. However, since for some biofuels indirect emissions—including from land use change—can lead to greater total emissions than when using petroleum products, policy support needs to be considered on a case by case basis” ( IPCC 2014 Chapter 8 ).

Climate change is one of the most pressing challenges facing our planet today.

The way we manage our lands can either accelerate or slow the rate of climate change.

After the first correction was published, several people contacted the  JEP  to point out more issues with the paper.
