At a time when climate change impacts are accelerating, our ability to observe those impacts from space is deteriorating.
Cuts in US government funding for Nasa programmes will dramatically weaken scientists' capacity to monitor and understand the planet's climate; at least, so says a major study from the National Research Council (NRC), published earlier this year.
If present trends continue, they conclude, by 2015 the number of US Earth-observing satellite missions will be reduced by half, putting the scientific systems they support "at risk of collapse."
They warn that such a loss would severely hamper the ability of scientists to collect basic information about the Earth's climate system, to monitor changes - including those that directly affect human health, such as disease outbreaks and water contamination - and provide accurate weather forecasts.
Programmes involving measurements of temperature, ozone, ocean winds, water vapour, and solar radiation are among those expected to be curtailed.
