Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future ...
We rely on climate models to predict the future, but models cannot be fully tested as climate observations rarely extend back more than 150 years. Understanding the Earth's past climate history across a longer period gives ...
