Sea ice briefing documents Monitoring sea ice at the poles To keep government informed about the state of the sea ice, scientists from the Met Office Hadley Centre produce sea ice briefings each year which are released at roughly monthly intervals throughout the summer. This page provides some

the continued rise in atmospheric carbon dioxide concentrations has been absorbed in the ocean and has not been manifest as a rise in surface temperature. Changes in the exchange of heat between the upper and deep ocean appear to have caused at least part of the pause in surface warming, and observations
