• Resumen

  • The article discusses research by climate scientists in which they attempt to reconstruct rainfall history across the ocean since A.D. 800 in order to gain a better understanding of how the increasing amount of atmospheric greenhouse gases (GHGs), rising atmospheric temperatures, and changes in tropical precipitation will alter climate patterns through 2100. Topics include an overview of Earth's primary precipitation band, known as the Intertropical Convergence Zone (ITCZ), the team's research methodology, which included measuring the characteristics of various ecosystems to better understand earlier climate patterns, and the team's prediction that Earth's wet regions will become dry.
