Scientists are learning more about the changes to ecological systems caused by the disruption of natural timetables. They want to know why we are losing species at such a fast rate. “It opens up the possibility that biological timing is going to respond in unexpected ways to the onslaught of different stresses that natural systems are experiencing, and the responses could be bigger than expected.”

About 9% of Earth’s population lives without clean water. A majority live in poor rural communities in countries that are most vulnerable to effects of climate change. Some of those effects, notably drought, reduce the basic supply of water, while others, like cyclones or floods, may cause a complete loss of access to water that is not badly polluted. India has the highest concentration of exposure to all of these problems.

New light is shed on the importance of trees and forests in preserving a livable climate. It goes far beyond the storage of carbon. “… older knowledge and new research findings point at the important effects of trees on helping to retain water on the ground and to produce cooling moisture, which in turn have a positive impact on food security and climate change adaptation.”

Deep ocean water is being warmed faster than predicted by climate models. The effect helps to keep heat out of the atmosphere, which is fine, but it’s not good for the oceans. Scientists have theories about how and why this is happening, and are setting up ways to gain the necessary evidence.

Research shows that warming temperatures causing changes in wind patterns greatly magnify the effects of air pollution in China. “Our results suggest that the issue of tackling Beijing’s severe haze needs to be examined in conjunction with global climate change.” Chinese scientists were involved in the study, which is important because the Chinese government has given much attention to policies that mitigate air pollution but only a little to the much broader need to reduce carbon emissions. The latter should now be more in line for a boost.
