Mediterranean, semi-arid ecosystems prove resistant to climate change
Climate change predictions for the Middle East, like other arid regions of the world, are alarming. But in testing these dire predictions, Tel Aviv University ecologists found that, contrary to expectations, no measurable changes in annual vegetation could be seen. None of the crucial vegetation characteristics -- neither species richness and composition, nor density and biomass -- had changed appreciably in the course of the rainfall manipulations.

In between red light and blue light
Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth's atmosphere and perform around one-quarter of the global CO2 assimilation, i.e. they convert carbon dioxide into organic substances. Their light receptors are a crucial factor in this process. Researchers at Leipzig University and UFZ have now discovered that blue and red light sensing photoreceptors control the carbon flow in these algae.

Improved electricity access has little impact on climate change
Expanding access to household electricity services accounts for only a small portion of total emission growth, shows a new study from the International Institute for Applied Systems Analysis, shedding light on an ongoing debate on potential conflicts between climate and development.
