Has the UN Climate Assessment Process Become Obsolete?

Peter Fairley for InsideClimate News Sept 8, 2017

The sweeping multi-year assessments produced by the Intergovernmental Panel on Climate Change set the gold standard for global scientific consensus on how humanity is altering Earth’s climate, and how to anticipate and minimize those changes. Some top climate scientists, however, are reviving a harsh critique of the IPCC’s assessment process, saying that it takes too long and that the delay could actually be creating an excuse for political inaction.

That process is moving forward this week with little sign of changing as scientists and government officials meet in Montréal to nail down a detailed blueprint for the sixth assessment since the IPCC’s creation in 1988. On Wednesday, IPCC Chair Hoesung Lee called the meeting the “most important” in the production cycle for what will become IPCC Sixth Assessment Report—a cycle that began in 2015 and will not conclude until 2022.

That seven-year schedule is simply unacceptable for a document that is “relied on by countless decision makers around the world every day,” said Katharine Hayhoe, an atmospheric scientist and co-director of the Climate Science Center at Texas Tech …

Trump Dumps Climate Science and Innovation in 2018 Budget Blueprint

NASA’s telescope on DSCOVR snapped a solar eclipse over South America in February

Al Gore didn’t really claim to invent the Internet in 1999, but he did champion a NASA mission that installed a deep space webcam pointed at Earth in 2015. And yesterday President Trump put a bullseye on that mission. Or, rather, on part of it. Trump’s 2018 budget blueprint asks Congress to defund the Earth-facing instruments on the Deep Space Climate Observatory (DSCOVR). Its sensors tracking magnetic storms emanating from the Sun would keep doing their jobs.

Selectively deep-sixing well-functioning instruments on a satellite 1.5 million kilometers from Earth is one of the stranger entries in President Trump’s first pass at a budget request. But it fits a pattern: Throughout the document programs aimed at comprehending or addressing climate change take deep cuts, even where there is no obvious fiscal justification. Continue reading

Rendering Greenhouse Gases Visible

Natural gas has no odor, but you can smell a leak thanks to the addition of an odorific mercaptam compound. Do carbon dioxide and other similarly odorless greenhouse gases (GHGs) require some analogous device to make their presence known and thus prompt evasive action? Yes, and for these ubiquitous gases, it will be a visual cue indicating the source and quantity of GHGs Continue reading

Applying ‘Trust, but verify’ to Climate Change Policy

Last year Swiss researchers demonstrated that European countries release more of the potent greenhouse gas trifluoromethane than they report. It was just the latest in a growing number of case studies showing that polluters and governments might be under-estimating their climate change impact, but it served to highlight the science and technology that can reveal such cheating Continue reading
