Why is Antarctic Sea Ice Growing?

Despite increases in global ocean temperatures, long-term trends actually show an increase in Antarctic sea ice extent. There are a number of reasons for this apparent paradox: geography, ocean properties, and atmospheric circulation to name a few. This paper examines the role of atmospheric variability in driving Southern Hemisphere sea ice trends. Channing PrendI’m a […]

Pole wars: Episode 1 – The Phantom Sea Ice

In the sea ice battle between the North Pole and the South Pole, there is no winner in 2016, as sea ice cover is plummeting at both poles. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in […]

Looking to the tropics to explain Antarctica’s expanding ice

Scientists confirm an surprising explanation for Antarctica’s expanding sea ice in the tropical Pacific Ocean. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For my research I sometimes spend months at sea on ice breakers […]

Ocean robots record California’s latest hot year

Using underwater gliders, researchers explain what caused the extremely warm ocean along the coast of California in 2014-2015 and what this might mean for local ecosystems. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For […]

Overfishing and climate variability interactions spell trouble for fast growing species

Rather intuitively, terrestrial ecosystems show that large, slow growing species are less adaptable in the face of environmental perturbations than their smaller, faster growing counterparts. However, in marine systems, harvest of all types of species, both fast and slow growing, switches the risk of collapse. Recent modelling work shows that in the face of overfishing […]

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. Hillary ScannellHillary received her MS in oceanography from the University of Maine in 2014 and works in the […]

On the Verge: Sea Level to Emerge

What is natural and what is human induced climate change? A controversial topic indeed, determining when a natural process has been drastically altered by human activities is best left to the scientists! In this study, scientists use climate model simulations and sea level projections to estimate when human induced climate change emerges from natural variability. […]
