From the ice sheets of Antarctica and the seabed of the Atlantic, to the boreal forests of Europe and corals of southeast Asia, proxy data is found across the Earth’s land and ocean.
NOAA holds an archive of more than 10,000 proxy datasets covering more than a dozen categories. With its permission, Carbon Brief has mapped this data.
Use the categories in the legend on the left to select a particular proxy or archive type, and the buttons in the top-right hand corner to zoom in and out. Clicking on an individual data point will reveal the period covered by the data, the site name and a link to NOAA’s reference webpage for further information.
Two stalagmites collected from a cave in Iran recorded the changing climate over 128,000 years. Analyzing their chemical composition led researchers to conclude that relief from the region’s current dry spell is unlikely within the next 10,000 years.
Before we can make a plan to protect our oceans from climate change, we need to know what they were like before human impact. We haven’t been collecting ocean data for very long, but luckily one ocean marine organism has been keeping records for millennia: corals. Paleoceanographer Nathalie Goodkin shows us how looking at evidence of the past in coral records can help us to protect these organisms, and our oceans, for the future.

Coral Cores - windows into past climate
Welcome to the blog of the Climate: Past, Present and Future (CL) Division of the European Geosciences Union (EGU). It cover all aspects of the ocean-climate-atmospheric systems, encompassing multiple, over-lapping and complementary disciplines, from the state of the current climate to modelled predictions of future climatic scenarios, and the reconstruction of past climatic change
The temperate region of Western Europe underwent significant climatic and environmental change during the last 15 deglaciation. Much of what is known about the terrestrial ecosystem response to deglacial warming stems from pollen preserved in sediment sequences, providing information on vegetation composition.
