Study: U.S. droughts can be explained by ocean forcing

Sea surface temperature can nudge the atmosphere into conditions, subsequently exacerbated or moderated by atmospheric variability, that can lead to drought. In this paper, authors Richard Seager (Lamont-Doherty Earth Observatory, Columbia University) and Martin Hoerling (NOAA ESRL) examine the causes … Continue reading

El Niño Residuals Cause the C-Shaped Warming Pattern in the Pacific

In the recent model-data comparison of satellite-era sea surface temperature anomalies—appropriately titled Maybe the IPCC’s Modelers Should Try to Simulate Earth’s Oceans—we compared trend maps of modeled and observed sea surface temperature anomalies from 1982 to 2013. See Figure 1. … Continue reading

IPCC on acid – if they are virtually certain about ocean acidification, why does X-prize offer a reward for designing a proper ocean pH meter?

The IPCC writes in the “leaked” SPM It is very likely that oceanic uptake of anthropogenic CO2 results in acidification of the ocean. The pH 44 (see 7) of seawater has decreased by 0.1 since the beginning of the industrial … Continue reading
