Loss of biodiversity appears to affect ecosystems as much as climate change, pollution and other major forms of environmental stress, according to results of a new study.

Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study. There has been growing concern that the very high rates of modern extinctions — due to habitat loss, overharvesting and other human-caused environmental changes — could reduce nature’s ability to provide goods and services like food, clean water and a stable climate.

A new report says that budget shortfalls, cost-estimate growth, launch failures, and changes in mission design and scope have left US Earth observation systems in a more precarious position than they were five years ago.

A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.
