A new study considers the complications of projecting impacts on carbon uptake by Earth ecosystems as the planet warms. The synthesis of organic compounds by primary producers from atmospheric or aqueous carbon dioxide is known as primary production. Almost all organisms on Earth directly or...

The Southern Annular Mode (SAM), the predominant mode of atmospheric variability in the Southern Ocean, has shifted to a positive polarity in recent years, resulting in a poleward displacement and strengthening of the circumpolar westerlies. In some regions of Antarctica, a positive SAM has been...

The average temperature of the planet is rising but increases in the frequency and severity of high and low temperature extremes are also expected. Most climate change research focuses on the possible effects of average rise in temperature, but in some cases changes in temperature extremes may be...

Studies have shown that variation in species responses to changing climate will result in disruption of biotic interactions such as predation, parasitism, competition, and mutualism, ultimately leading to changes in community composition and ecosystem functioning (e.g., Both et al. 2009). Just as...

Along with their obvious benefits, agriculture and food production have significant environment impacts: Carbon dioxide emissions result from the power requirements of farm machinery and from the transport, storage and cooking of food. Nitrous oxide (a potent greenhouse gas) is released from soils...

Volcanic eruptions are generally considered one of the best-understood (and most dramatic) causes of sudden climate changes, with large explosive eruptions capable of causing severe short-term cooling on hemispheric and global scales. This mainly occurs when eruptions inject large volumes of sulfur...

One of the most feared consequences of climate warming is the potential expansion of tropical infectious diseases. However, for diseases that require intermediate hosts a warmer climate and the particular dynamics of the disease can actually reduce transmission in some cases. A recent study by...
