The upward trend in atmospheric carbon dioxide is accompanied by a trend in the carbonate system, oxygen concentrations, and temperatures of the global ocean, but in coastal environments, local and regional processes can modulate or exacerbate these trends. Coastal and regional processes can occur on spatial scales that are not well represented…
Earth’s climate is chaotic and noisy. Finding usable signals amidst all of the noise can be challenging. Here, I will demonstrate how explainable artificial intelligence (XAI) techniques can sift through vast amounts of climate data and push the bounds of scientific discovery. Examples include extracting robust indicator patterns of climate…
While it is generally accepted that the stratospheric Brewer-Dobson circulation is a wave-driven phenomenon, there are some characteristics of stratospheric tropical upwelling that remain poorly understood. For instance, why is there upwelling in the tropics at the equator, and not in the sub-tropics? Solutions to steady forcing in a simple…

The distribution of water resources over land highly varies in space and time. From local to global scales,…
Forests are major drivers of biophysical land-atmosphere feedbacks, the global carbon and water cycles, and thus overall planetary climate regulation. However, large uncertainties and substantial debate persist regarding ongoing and potential changes in the capacity of forests carbon sinks under anticipated future climate change. In this talk,…
While the intensity of the global ocean carbon uptake is well constrained using data driven as well as modeling approaches, the quantification of the net CO2 exchange between the coastal ocean and the atmosphere is still not quite as well understood and some debate remains regarding whether some poorly monitored regions behave as sources or…
A recent review asserts that the past million years are the most difficult times to test the Milankovitch (Ice Age) hypothesis. However, if the climate record is regarded as the score of a musical composition, then the recurrent saw-tooth signal -- a prolonged cooling (glaciation) trend followed by a brief warming …
Anthropogenic carbon emissions increase the atmospheric CO2 and lead to surface warming. The ocean mitigates this climate response through the uptake of carbon; but at the same time, the increase in the ocean’s carbon content and climate change modify the ability of the ocean to absorb carbon through their effects on the ocean’s physical…
