The connection between orbital mechanics, solar variability and climate is complex. I don’t know the answer, but this post will bring you up to date.

Climate Oscillations 11: Oceanic Niño Index (ONI)
ENSO affects weather all over the world but doesn’t track the global mean surface temperature (GMST), at least for the last 35 years. Is GMST an appropriate measure of climate…
Climate Oscillations 10: Aleutian Low – Beaufort Sea Anticyclone (ALBSA)
The Aleutian Low – Beaufort Sea Anticyclone climate index or ALBSA is designed to predict snow and ice melting times on the North Slope of Alaska.
Climate Oscillations 9: Arctic & North Atlantic Oscillations
The AO and NAO are the dominant modes of climate variability in the Northern Hemisphere and neither of them can be reproduced using climate model output.
Climate Oscillations 8: The NPI and PDO
The NPI and PDO are closely related and do not correlate well with global warming.
Climate Oscillations 7: The Pacific Mean SST
This is a comparison of Pacific SST to HadCRUT5, how we4ll do they compare?
Climate Oscillations 6: Atlantic Meridional Mode (AMM)
By Andy May The Atlantic Meridional Mode Index (AMM) describes meridional variability in the tropical Atlantic. The area of interest is the ocean area inside 32°N to 21°S and from…
Climate Oscillations 5: SAM
The Southern Annular Mode (SAM) has a major influence on global climate.
Climate Oscillations 4: The Length of Day (LOD)
The Length of Day correlates with meridional circulation and global warming and cooling.
Climate Oscillations 3: Northern Hemisphere Sea Ice Area
Can we model Northern Hemispheric sea ice or the Northern climate oscillations? Not likely.
Climate Oscillations 2: The Western Hemisphere Warm Pool (WHWP)
By Andy May As seen in the first post of this series the AMO (Atlantic Multidecadal Oscillation) and the WHWP (Western Hemisphere Warm Pool) area are the two climate oscillations…
Climate Oscillations 1: The Regression
By Andy May Introduction to the “Climate Oscillations” series My last two posts, Musings on the AMO and The Bray Solar Cycle and AMO were fun to research and write,…
The Bray Solar Cycle and AMO
By Andy May My last post on the AMO and HadCRUT5 generated some interest and some criticism. As I explained, there are two common methods of computing the AMO index.…
Musings on the AMO
Does the Atlantic Multidecadal Oscillation (AMO) play a role in global warming? Or does global warming affect the AMO? We take a look.
Energy Consumption in 2024 and the Spanish Power Failure
What does the April 2025 Spanish power failure tell us about how we compare solar and wind to stable fossil fuel and nuclear power generation? By Andy May Global energy…
The Weather and Climate of World War II
By Andy May This post has been translated into German for those who prefer it here. In my last post I discussed the evolution from the ICOADS raw sea surface…
What is the Global Average SST?
By Andy May The global average SST (Sea Surface Temperature) is a very important component of the global average surface temperature for the simple reason that the global ocean covers…
Plate Tectonics and Climate during the Cenozoic
By Andy May In this post I examine the proxies used to compare CO2 to temperature from 66 million years ago (Ma) until today and comment on the quality of…
The Earth without Greenhouse Gases
By Andy May The overall greenhouse effect (GHE) is often defined as the difference between Earth’s average global temperature without greenhouse gases (GHGs) and with them. Greenhouse gases are all…
Beyond CO₂: Unraveling the Roles of Energy, Water Vapor, and Convection in Earth’s Atmosphere
Watts Up With That? is committed to fostering open discourse on climate science and related topics. While we respect the authors’ perspective and their dedication to exploring climate dynamics, we…
