Climate adaptation follies. Part II: scenarios of future sea level rise — Climate Etc.

by Judith Curry How did the state of New Jersey come to adopt sea level rise projections for their adaptation planning that are more than twice as high as the IPCC’s values? Part I introduced the challenges facing New Jersey associated with sea level rise, and their general adaptation strategy. Their adaptation strategy is driven […]

Climate’s uncertainty principle — Watts Up With That?

Reposted from Dr. Judith Curry’s Blog, Climate Etc. by Garth Paltridge On the costs and benefits of climate action. Whether we should do anything now to limit our impact on future climate boils down to an assessment of a relevant cost-benefit ratio. That is, we need to put a dollar number to the cost of…

Why climate predictions are so difficult — Watts Up With That?

 

From Climate Etc. by Judith Curry An insightful interview with Bjorn Stevens. Frank Bosse provided this Google translation of an interview published in Der Spiegel -Print-Issue 13/2019, p. 99-101. March 22, 2019 Excerpts provided below, with some minor editing of the translation. begin quote: Global warming forecasts are still surprisingly inaccurate.

Four fronts for climate policy — Watts Up With That?

 

Reposted from Judith Curry’s Climate Etc. Posted on March 25, 2019 by curryja by Judith Curry “For decades, scientists and policymakers have framed the climate-policy debate in a simple way: scientists analyse long-term goals, and policymakers pretend to honour them. Those days are over. Serious climate policy must focus more on the near-term and on…

Hurricanes & climate change: detection — Watts Up With That?

 

From Dr. Judith Curry’s Climate Etc. Posted on February 17, 2019 by curryja | by Judith Curry I am preparing a new Special Report on Hurricanes and Climate Change. This Report is easier than my Special Report on Sea Level and Climate Change. Sea level and glaciers are very fast moving topics, whereas for hurricanes,…

National Climate Assessment: A crisis of epistemic overconfidence — Climate Etc.

by Judith Curry “You can say I don’t believe in gravity. But if you step off the cliff you are going down. So we can say I don’t believe climate is changing, but it is based on science.” – Katherine Hayhoe, co-author of the 4th National Climate Assessment Report.

Cliff Mass: victim of academic political bullying — Watts Up With That?

 

Reposted from Judith Curry’s Climate Etc. by Judith Curry There is a disturbing story coming out of the University of Washington surrounding Cliff Mass. In preparing this article, I have received material from a member of the Department of Atmospheric Sciences at the University of Washington. I also ran into another member of the Department…

Climate sensitivity to cumulative carbon emissions — Climate Etc.

By Nic Lewis An observational estimate of transient (multidecadal) warming relative to cumulative CO2 emissions is little over half that per IPCC AR5 projections. AR5 claims that CO2-caused warming would be undiminished for 1000 years after emissions cease, but observations indicate that it would halve.

CAGW: a ‘snarl’ word? — Watts Up With That?

 

Reposted From Judith Curry’s Climate Etc. By Andy West The term ‘CAGW’ has both appropriate and inappropriate usage. Introduction Rational Wiki says: ‘“CAGW”, for “catastrophic anthropogenic global warming”, is a snarl word (or snarl acronym) that global warming denialists use for the established science of climate change. A Google Scholar search indicates that the term…

Will advances in groundwater science force a paradigm shift in sea level rise attribution? — Climate Etc.

by Jim Steele A better accounting of natural groundwater discharge is needed to constrain the range of contributions to sea level rise. The greater the contribution from groundwater discharge, the smaller the adjustments used to amplify contributions from meltwater and thermal expansion.

Nature Unbound VIII – Modern global warming — Climate Etc.

by Javier Summary: Modern Global Warming has been taking place for the past 300 years. It is the last of several multi-century warming periods that have happened during the Neoglacial cooling of the past 3000 years. Analysis of Holocene climate cycles shows that the period 1600-2100 AD should be a period of warming. The evidence […]

Is climate change the culprit causing California’s wildfires? — Climate Etc.

by Larry Kummer We’re told that climate change caused or intensified California’s wildfires — and that such fires are getting worse. As usual for such scary stories, these claims are only weakly supported by science — except for the ones that are outright fabrications.

Nature Unbound VI – Centennial to millennial solar cycles — Climate Etc.

by Javier Summary: Holocene climate has been affected in different periods by several centennial to millennial solar cycles. The ~ 1000-year Eddy solar cycle seems to have dominated Holocene climate variability between 11,500-4,000 years BP, and in the last two millennia, where it defines the Roman, Medieval, and Modern warm periods. The ~ 208-year de […]

Are Climate Models Overstating Warming? — Watts Up With That?

From Climate Etc. by Ross McKitrick A number of authors, including the IPCC, have argued that climate models have systematically overstated the rate of global warming in recent decades. A recent paper by Millar et al. (2017) presented the same finding in a diagram of temperature change versus cumulative carbon emissions since 1870. The horizontal […]
