What can sea level tell us about long-term climate variability in the Atlantic?

Ocean circulation plays a major role in delivering heat to the subpolar North Atlantic and influence long-term changes in sea surface temperatures. A cleaver use of tidal gauge data shows that we are in for a natural transition to cooler temperatures in the North Atlantic with unfavorable consequences for coastal sea level rise along the US northeastern seaboard.

Indian Ocean keeps the Pacific cool

Inter-ocean heat transport through Indonesia’s archipelago offloads excess heat from the tropical Pacific to the Indian Ocean. Findings emphasize the importance of ocean heat transport in solving Earth’s energy imbalance.

Global temperatures: an uphill battle of warm vs. cold

An illusional and fanciful pause in global warming has climate change skeptic buzzing. Understanding the decadal oscillations of natural climate variability places transient pauses in global warming in perspective. Spoiler: we’re still trending towards a warmer climate.

Cooling in North Atlantic Defies Global Warming

Sluggish ocean circulation can’t keep up with global climate change and this has caused the North Atlantic to cool.

Sensors probe oceans for answers

Deep-diving ocean drones confirm continued warming of the ocean’s abyss due to Earth’s energy imbalance.

Extreme La Niña driven by big El Niño under future warming

The succession of ENSO events is projected to become more frequent and intense in a warming climate.

We’re In Deep Heat: trouble boils over in West Antarctica

An international team of researchers shows that rising ocean temperatures along West Antarctic ice shelves are linked to rising warm water from the deep ocean, and that the rate of warming is larger than previously thought. With no indication of a slow down in warming, these findings illuminate on new realities of sea level challenges likely to be faced in coming decades.

Species respond differently to climate shifts over time

Large-scale climate variably is well-known to have impacts on marine ecosystems. However, the response of species over time is not as simple as it seems. This study reveals that the relationships between seabirds and Pacific climate varies over time.

The results are in: Ecosystems attune to natural temperature changes

Understanding both physics and biology is crucial in identifying the impacts of climate change on marine ecosystems. This meta-analysis on the ecological responses to natural temperature swings provides an overview of the Atlantic biophysical marine system.

Zooplankton versus Phytoplankton: a trophic seesaw

NASA satellites reveal artistic swirls of phytoplankton dancing across the ocean surface. This new study explains the dynamic predator-prey imbalances that occur to create these spectacular space-worthy images.

How is the tropical Pacific causing the Arctic to warm?

The Arctic is warming at an unprecedented rate. New research shows that 50% of regional Arctic warming is due to natural climate variations, while the other 50% is due to human-induced climate change.

Cyclones move poleward as tropics expand

Tropical cyclones are escaping the hot tropics and intensifying closer towards the poles. The apparent expansion of the tropics helps us to understand why.
