The Rate of Sea-Level Rise

A new study paper out in nature (Nature Climate Change / 2014 / doi:10.1038/nclimate2159), explores why the rise of sea-level has slowed in the last decade. Unsurprisingly the slow-down coincidences with the observed climate hiatus (IPCC AR5, Ocean heat content uptake). Because  heat is distributed differently, depending on the state of ENSO (between El Nino or La Nina). Abstract: Present-day sea-level…

Global Warming Speed Bump? The Answer May Be Blowing in the Wind!

By Michael E. Mann via HuffingtonPost: An interesting new paper by Matthew England and colleagues just published in the journal Nature Climate Change tosses another hat in the ring when it comes to explanations of the so-called “hiatus” or “pause” (I prefer “speed bump”) in global warming. As I have discussed previously, the fact that global surface temperatures have not increased…

2013 was the second-hottest year without an El Niño since before 1850

The Guardian: According to the global surface temperate data set compiled by Kevin Cowtan and Robert Way, which achieves the best coverage of the rapidly-warming Arctic by filling in data gaps between temperature stations using a statistical method called kriging, 2013 was the 5th-hottest year on record (since 1850). The top three hottest years (2010, 2005,…

Global warming could change strength of El Nino

Via Phys.org September 11, 2013: Global warming could impact the El Niño Southern Oscillation (ENSO), altering the cycles of El Niño and La Niña events that bring extreme drought and flooding to Australia and many other Pacific-rim countries. New research published in Nature Geoscience using coral samples from Kiribati has revealed how the ENSO cycle has changed…

World ocean heat content and thermosteric sea level change (0 – 2000 m), 1955 – 2010

S. Levitus, J. I. Antonov, T. P. Boyer,O. K. Baranova,H. E. Garcia,R. A. Locarnini,A. V. Mishonov,J. R. Reagan,D. Seidov,E. S. Yarosh, and M. M. Zweng | published 17 May 2012 Abstract We provide updated estimates of the change of ocean heat content(OHC) and the thermosteric component of sea level change of the 0–700 and 0–2000…

Does Sea Ice loss create the condition for an emerging permanent El Nino state?

Recently Doug asked: “…my question is, how far could this phenomenon go? What is the “end” state? Is it possible for example that we could find the jet stream staying in place for months at a time, years, decades? How wavy could this waviness become?” A main theme of Sea ice loss seems to be…

A Looming Climate Shift: Will Ocean Heat Come Back to Haunt us?

By Rob Painting / SkepticalScience, June 24, 2013: Key Points: Despite a large increase in heat being absorbed by the Earth’s climate system(oceans, land & ice), the first decade of the 21st century saw a slowdown in the rate of global surface warming (surface air temperatures). A climate model-based study, Meehl (2011), predicted that this…
