New Paper Confirms the Drivers of and Processes behind the Atlantic Multidecadal Oscillation
Guest Post by Bob Tisdale The new paper by McCarthy et al. (2015) Ocean impact on decadal Atlantic climate variability revealed by sea-level observations has gained some attention around the…
New paper: The Atlantic Multidecadal Oscillation as a dominant factor of oceanic influence on climate
Just two explanatory variables (GHG and AMO) still account for 93% of the temperature variance. Dr. Leif Svalgaard sends word of this article in Geophysical Research letters by Petr Chylek,…
On Chylek et al (2014) – The Atlantic Multidecadal Oscillation as a Dominant Factor of Oceanic Influence on Climate
I was advised of a recent paper that studies the impact of the Atlantic Multidecadal Oscillation on global surface temperatures since 1900. (Thanks, Anthony.) The paper is Chylek et al.…
Tisdale: How Much of an Impact Does the Atlantic Multidecadal Oscillation Have on Arctic Sea Ice Extent?
Last week I asked Bob Tisdale to take a hard look at potential correlations between the AMO and Arctic sea ice extent, and he rose to the challenge – Anthony…
The Atlantic Multidecadal Oscillation – not quite cool yet.
From ICECAP AMO, The Key Global Climate Indicator By Matt Vooro The AMO is an ongoing series of long-duration changes in the sea surface temperature of the North Atlantic Ocean,…
Model vs Model: Is the North Atlantic Current Collapsing?
12,900 years ago the North Atlantic Current failed, likely due to the emptying of an enormous glacial lake. This catastrophic lake failure is believed to have disrupted ocean currents, which…
Predicting Atlantic Hurricanes Using Machine Learning
Our forecast is that no category 5 hurricanes will be formed in the Atlantic until the next active decadal oscillation phase around 2026±2 to 2031±3
“Major Scientific Breakthrough”…Scientists “Step Closer To Predicting North Atlantic Climate”
A team of scientists believe they’ve made a forecasting breakthrough, suggesting the NAO is in fact highly predictable.
Record Atlantic Hurricane Season?
There has been much alarum about last year being a “record Atlantic hurricane season”. As I pointed out at the time, the claim was based on the number of named…
Internal Multidecadal and Interdecadal Climate Oscillations: Absence of Evidence Is No Evidence of Absence
Altogether, I conclude that the paper M20 is not advancing our understanding of the nature of multi- and interdecadal oscillations such as the AMO and PDO.
NOAA claims: “Extremely active” hurricane season possible for Atlantic Basin
Atmospheric and oceanic conditions are primed to fuel storm development in the Atlantic, leading to what could be an “extremely active” season, according to forecasters with NOAA’s Climate Prediction Center,…
North Atlantic climate far more predictable following major scientific breakthrough
A team of scientists, led by UK Met Office, has achieved a scientific breakthrough allowing the longer-term prediction of North Atlantic pressure patterns, the key driving force behind winter weather…
2019 Atlantic hurricane forecast
From Judith Curry’s Climate Etc. Posted on June 4, 2019 by curryja by Judith Curry and Jim Johnstone CFAN predicts an active North Atlantic hurricane season season. The Atlantic hurricane…
Sorry alarmists: Hurricanes are developing more quickly today than 30 years ago due to the Atlantic ocean cycle
Pierre Gosselin writes: Here’s something you don’t witness very often…German national public radio telling listeners that natural factors are behind observed changes in something related to climate. I can’t tell…
The 60-year oscillation revisited
Guest Post by Javier It is a well-known feature of climate change that since 1850 multiple climate datasets present a ~ 60-year oscillation. I recently wrote about it in the…
North Atlantic Oscillation phases, tree growth, and droughts
From the UNIVERSITY OF THE BASQUE COUNTRY, and the “climate phenomena not related to CO2” department. Droughts and ecosystems are determined by the interaction of two climate phenomena What is causing…
Robust relationship between solar wind speed and North Atlantic Oscillation discovered
Interdisciplinary studies reveal relationship between solar activity and climate change INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES The solar flux is considered the fundamental energy source of earth’s climate…
Evidence that multidecadal Arctic sea ice has turned the corner
Guest essay by Javier* Arctic sea ice has been on a declining trend since at least 1979, and probably since the bottom of the Little Ice Age. 2007 was a…
Study: There is no real evidence for a diminishing trend of the Atlantic Meridional Overturning Circulation
This paper was just published today in the Journal of Ocean Engineering and Science. It seems to be definitive refutation of Mann and Rahmstorf’s claims, and quells the alarm bells that…
On Steinman et al. (2015) – Michael Mann and Company Redefine Multidecadal Variability And Wind Up Illustrating Climate Model Failings
Guest Post By Bob Tisdale For the past few years, we’ve been showing in numerous blog posts that the observed multidecadal variations in sea surface temperatures of the North Atlantic…
New Study Predicts a Slight Cooling of North Atlantic Sea Surface Temperatures over the Next Decade
Guest Post by Bob Tisdale Pierre Gosselin at NoTrickZone provided an introduction to a recently published paper in his post IPCC Scientist Mojib Latif Sees North Atlantic Cooling Over Next…
And this excuse makes 30. Dueling press releases on 'the pause', blaming Pacific Trade Winds on 'Atlantic warming'
Previously, we had 29 excuses for “the pause” now we have 30. When a paper is published by multiple authors, the universities of those authors often produce separate press releases…
