A new study has determined that due to climate change, the composition of algae is changing, as a result of which their nutritional value for other aquatic life is decreasing.

This is the conclusion of researchers from the Netherlands Institute for Ecology (NIOO-KNAW) and the Universiteit van Amsterdam.
President Obama Could Make a Difference to Climate Change Strategy
Unlike George W Bush Jr, the new President of the USA seems to be serious about the climate change crisis. There is buzz of intense diplomatic activity across the world.

They therefore examined freshwater micro-algae: small, floating and mostly unicellular algae.
The experiments were performed in large tanks called limnotrons. These were aerated with ordinary air or with air containing an elevated concentration of CO2.
Aerosols may Have Greater Impact on Climate Change Than Thought So Far
Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought.

The micro-algae grew faster at a higher CO2 concentration, exactly as the researchers had expected. Yet, this growth was also associated with a change in the composition of the algae.

This meant a reduction in the nutritional value, which could have detrimental effects upon the small animals that eat the algae such as water fleas.

Spread of harmful algae across the globe may be predicted by DNA test
A DNA test to predict which parts of the globe may be hit by harmful algal blooms has been developed by University of Connecticut researchers.
