Slowdown in temperature rise since 2000 can be attributed to oceans
A recent study from the Institut Català de Ciències del Clima (IC3) found that the pause in global temperature rise, occurring despite the ongoing emission of greenhouse gases, is mainly due to an increase in ocean heat uptake. Other causes include a deep prolonged solar minimum, the stratospheric water vapour and the stratospheric and tropospheric aerosols.

Seasonal forecast skill of Arctic sea ice area in a dynamical forecast system
Scientists from the Department of Physics, University of Toronto and the Canadian Centre for Climate Modelling and Analysis, Victoria, Canada, assessed the seasonal forecast skill of pan-Arctic sea ice area in a dynamical forecast system that includes interactive atmosphere, ocean, and sea ice components.

Changes in Arctic sea ice result in increasing light transmittance and absorption
The thinner and younger the ice, the larger the transmittance and absorption, increasing sea-ice melt and affecting ecosystems. These are among the findings of a study by the Alfred Wegener Institute for Polar and Marine Research (AWI), which investigated the effects of light penetrating through sea ice into the upper ocean.

More hurricanes to hit western Europe due to global warming
In a recent study, scientists from the Royal Netherlands Meteorological Institute (KNMI) used a very high resolution global climate model to show that increased Atlantic tropical sea surface temperatures extend the breeding ground for tropical cyclones eastward, with pathways directed towards Europe.

Melting ice has less effect on sea-level rise than thought
The European Union Programme ice2sea ended its four years of research and presented a synthesis report on 15 May. It was able to reduce the uncertainty in projections of the contribution of ice sheets and glaciers to sea-level rise, and found its share to be smaller than previously estimated.

NASA Satellite Data Help Pinpoint Glaciers' Role in Sea Level Rise
A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.

Exploring the saltiness of the ocean to study climate change
Details are emerging from a recent research expedition to the Sub-Tropical North Atlantic. The objective of the expedition was to study the salt concentration (salinity) of the upper ocean. The scientists at the National University of Ireland Galway explored the essential role of the ocean in the global water cycle.
