Scientists have recovered the first genetic data from an extinct bird in the Caribbean, thanks to the remarkably preserved bones of a Creighton's caracara in a flooded sinkhole on Great Abaco Island i...
The identification of a solar signal in climate records of the last 500 years using proxy and model-based analysis and the implications for natural climate variability
Satellite instruments car the solar constant solar energy output climate the climate warming
