    Ocean acidification prediction now possible years in advance

    A team of researchers has developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades.

  3. Simulation of past climate shows recent models may be too sensitive to carbon dioxide

    A climate model simulation of the Early Eocene period roughly 50 million years ago returned temperatures that were too high compared to evidence in the geologic record, suggesting that the model may also project unrealistically high temperatures for the future.

    Arctic Ocean likely to become ice-free in the summer for first time before 2050

    The Arctic Ocean is likely to have its first ice-free summer before 2050, according to an analysis of simulations from more than 40 different climate models. How frequently the sea ice vanishes in the summer depends on the rate of greenhouse gas emissions in the future.
