How Global Warming Isn’t

Guest Post by Willis Eschenbach I kept reading that warming oceans around Antarctica are melting the ice shelves. However, I’ve also read that Antarctica hasn’t warmed in seven decades. Say…

Best Climate Change Temperatures

By Andy May I just gave an informal Zoom talk to a small group on measuring climate change through temperatures. The host, Dave Siegel, recorded it and has posted the…

Why do the HadSST Sea-Surface Temperatures Trend Down?

By Andy May The simple answer is that the portion of the ocean, roughly 54%, that has HadSST values is getting cooler. But Nick Stokes doesn’t believe that. His idea…

Ocean Temperatures, what do we really know?

By Andy May This is the last in my current series of posts on ocean temperatures. In our previous posts we compared land-based measurements to sea-surface temperatures (SSTs) and discussed…

Sea-Surface Temperature Anomalies

By Andy May My previous post on sea-surface temperature (SST) differences between HadSST and ERSST generated a lively discussion. Some, this author included, asserted that the Hadley Centre HadSST record…

Sea-Surface Temperatures: Hadley Centre v. NOAA

By Andy May My last post compared actual sea-surface temperature (SST) estimates to one another to see how well they agreed. It was not a pretty sight; the various estimates…

The Ocean Mixed Layer, SST, and Climate Change

By Andy May As described in my previous post, the ocean “mixed layer” is sandwiched between the very thin “skin” layer at the ocean surface and the deep ocean. The…

500 Years of Global SST Variations from a 1D Forcing-Feedback Model

If nothing else, the results in Fig. 3 might give us some idea of the ENSO-related SST variations for 300-400 years before anthropogenic forcings became significant, and how those variations…

Sea surface skin temperature

By Andy May In previous posts, see here and here, I’ve tried to show that because the oceans cover 71% of Earth and they contain 99% of the thermal energy…

Ocean Temperature Update

By Andy May A considerable amount of new information on ocean temperature has been gathered since I last wrote about the subject in 2016 here. In my last post on…

Claim: The deep sea is slowly warming

WASHINGTON–New research reveals temperatures in the deep sea fluctuate more than scientists previously thought and a warming trend is now detectable at the bottom of the ocean.

A new method for correcting systematic errors in ocean subsurface data

News Release 8-Apr-2020 A homogeneous, consistent, high-quality in situ temperature data set covering some decades in time is crucial for the detection of climate changes in the ocean. Systematic errors in…

New 80-Year Deep-Ocean Temperature Dataset Compared to a 1D Climate Model

Reposted from Dr. Roy Spencer’s site January 15th, 2020 by Roy W. Spencer, Ph. D. The increasing global ocean heat content (OHC) is often pointed to as the most quantitative…

The Ocean Warms By A Whole Little

Guest Post by Willis Eschenbach [see update at the end] How much is a “Whole Little”? Well, it’s like a whole lot, only much, much smaller. There’s a new paper…

Weak El Nino Conditions Help Explain Recent Global Warmth

From Dr. Roy Spencer’s Blog January 13th, 2020 by Roy W. Spencer, Ph. D. The continuing global-average warmth over the last year has caused a few people to ask for…

When Warming is Cooling!

Guest post by Jim Steele, Published in the Pacifica Tribune December 31, 2019 What’s Natural? When Warming is Cooling! The media has been awash with doomsday headlines, trumpeting a human-caused…

Geothermal ocean warming discussion thread

Reposted from Climate Etc. Posted on July 21, 2019 by curryja by Judith Curry “The atmosphere bias of climate science makes it impossible for them to see geological forces and…

Boaty McBoatface mission gives new insight into warming ocean abyss

The first mission involving the autonomous submarine vehicle Autosub Long Range (better known as ‘Boaty McBoatface’) has for the first time shed light on a key process linking increasing Antarctic…

Comparison of global climatologies confirms warming of the global ocean

Institute of Atmospheric Physics, Chinese Academy of Sciences IMAGE: Deployment of an APEX float from a German research ship. Credit: Argo The global ocean represents the most important component of…

Deep Ocean Warming in Degrees C

In recent weeks and months, there’s been a run of papers—with typical mainstream media misinforming embellishments—about improved estimates of the warming of the oceans…and blog posts about them. One thing…

Sad News: No More BLOB

From Cliff Mass Climate and Weather Blog Monday, December 24, 2018 Sad News: No More BLOB A lot of folks are interested in the BLOB, the colorfully named area of…

Earth’s polar regions communicate via oceanic ‘postcards,’ atmospheric ‘text messages’

From Eurekalert Oregon State University CORVALLIS, Ore. – Scientists have documented a two-part climatic connection between the North Atlantic Ocean and Antarctica, a fast atmospheric channel and a much slower…

Stephen, Why Global Warming is not a problem

By Andy May The following is a quote from my book Climate Catastrophe! Science or Science Fiction? “99.9 percent of the Earth’s surface heat capacity is in the oceans and…

Climate Change, due to Solar Variability or Greenhouse Gases? Part A.

By Andy May It’s more likely mostly due to both, but that isn’t really the question. Virtually everyone accepts that climate changes and that CO2 and methane are greenhouse gases;…
