Do the facts matter?

Do the facts matter?

Chris Mooney has an interesting piece on whether the climate change “consensus” is a useful policy approach. Is it changing the minds of people that formerly didn’t “believe in” climate change? And more broadly whether facts ever change minds. As two top researchers studying the science of science communication—a hot new field that combines public opinion research […]


Q: What does the new IPCC report say about sea level rise?

Q: What does the new IPCC report say about sea level rise?

A: Nothing good. See the plot below of observed past and predicted future sea level (rise). Note the two plotted future scenarios are based on the new Representative Concentration Pathways (RCPs): plausible trends in atmospheric CO2 (and other greenhouse gases) concentration named for the corresponding additional heat retained by 2100 in W m-2. For the past, proxy data are shown […]

Global imprint of climate change on marine life

Global imprint of climate change on marine life

An NCEAS working group I was a minor participant in has an important new paper out in Nature Climate Change (Poloczanska et al 2013 PDF). Summary: We synthesized all available studies of the consistency of marine ecological observations with expectations under climate change. This yielded a metadatabase of 1,735 marine biological responses for which either regional or global climate […]

Meet the new Representative Concentration Pathways (RCPs)

Meet the new Representative Concentration Pathways (RCPs)

The Intergovernmental Panel on Climate Change (IPCC) has replaced their older climate change scenarios with ‘Representative Concentration Pathways’ (RCPs) developed for IPCC AR5 report, scheduled to be published in 2014. Unlike the scenarios they replace (A1, B1, A1F1, etc.), the RCPs are not based on social, technological, and economic storylines. Instead, they are simply plausible […]


Continued coral reef accretion requires vastly reduced CO2 emissions

Continued coral reef accretion requires vastly reduced CO2 emissions

An important new modeling study (Kennedy et al 2013  download PDF) forecasts the structural decay of Caribbean reefs based on emission scenarios from the new ‘representative concentration pathways’ (RCPs). Excerpted  Authors Summary: Coral reefs face multiple anthropogenic threats, from pollution and overfishing to the dual effects of greenhouse gas emissions: rising sea temperature and ocean […]


Debunking National Review’s lies about climate change

In response to Obama’s historic speech and new policy on climate change, the American conservative media has gone, well, predictably bonkers.  Check out this editorial from National Review, which starts off with a lie: It is remarkable that when the scientific consensus on global warming is at its weakest state in years, President Barack Obama […]


Obama’s climate action plan

This has been a massive news week.  We started off with unrest in Brazil, more unrest in Turkey, more bloodshed and chaos in Syria, Snowden fleeing Hong Kong, the bombshell that the “IRS war on conservatives” was another GOP fantasy, and the SCOTUS overturning portions of the Voting Rights Act.  Then yesterday afternoon came Obama’s […]


Climate Change and Marine Communities 7: Blue Carbon

Climate Change and Marine Communities 7: Blue Carbon

This is the 7th installment of my serialization of a new book chapter on  “Climate Change and Marine Communities” written with Chris Harley and Mike Burrows. It is for a new book “Marine Community Ecology and Conservation” that I’m co-editing with Mark Bertness, Brian Silliman, and Jay Stachowicz. Blue Carbon To avoid long-term ecological degradation, it is becoming […]


Shrink That Footprint

I’m a sucker for carbon accounting and carbon source graphics and I love this simple one from shrinkthatfootprint.com which came from Lindsay Wilson’s post A short history of carbon emissions and sinks at Skeptical Science.  


Where greenhouse gases come from

Where greenhouse gases come from

Ecofys released a new, nice graphic depicting where greenhouse gases come from: It generally seems accurate and they say it is based on 2010 data, although I have not been able to find their methodology.  This chart updates an important, earlier one from WRI here.  In 2000 18.2 % of emissions were attributed to land use […]


Sea level rise in North Carolina

This is a post for my Marine Ecology class.  We covered estuaries yesterday and will get to climate change impacts on the oceans soon.  Sea level rise due to greenhouse gas emissions is one of the main ways climate change is affecting us Tar Heels.  (And yes, this will all be on the final exam) […]


The 97% consensus on human-caused climate change

The 97% consensus on human-caused climate change

If you believe the climate is changing and that human activties are the cause, then you can probably go back to cleaning your house or whatever you were doing when you took a break to check in with SeaMonster. But, if you are one of the hundred million or so Americans that still don't believe in this […]


Global warming since 1999

Global warming since 1999

Climate change deniers like to claim there has been “no warming since 1998” which was an especially warm year due to an intense El Nino.  Well that ain’t true.  Global warming has indeed continued, especially in the deep sea due to the prevalence of several La Nina events recently. Here is how much the land […]


Humans are causing more strong hurricanes

The possible effect of global warming on the frequency or severity of cyclonic storms has been debated quite intensely among scientists (not only between scientists and climate change deniers) for over a decade.  Several new studies are helping to clarify (somewhat) whether we are already experiencing (or will soon) more intense storms.  Dana Nuccitelli has a […]
