El Niño is marked by the appearance from time to time of warm water in the central and eastern Pacific Ocean. The end result of the evaporative process that follows is excessive rainfall.

Students will explore time series plots and raw data to understand the role of sea surface temperature increases on arctic ice melt. This is part three of a four-part activity on polar science. The activity builds on the knowledge gained in Using Data and Images to Understand Albedo (part 2). Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Information is provided on data access using the NOAA Earth System Research Laboratory Web site. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Most climate models tend to agree on the Earth’s future when it comes to temperature: at our current pace of greenhouse gas emissions, it’s going to get hotter everywhere. That makes intuitive sense. What’s less obvious is what’s going to happen to precipitation. Models are generally in much weaker agreement about precipitation changes, but they seem to converge in predicting that certain areas are definitely going to get wetter and others drier. Among these, the Mediterranean stands out. Locally, the region may lose up to 40% of its winter precipitation. For the millions who depend on these seasonal rains, it’s a serious threat to their way of life. But researchers have yet to explain why numerous climate models settle on the same fate. Now, researchers from MIT have discovered two mechanisms that could converge to create this dire scenario: strengthening winds in the upper troposphere, at an altitude of about 10 km, and a diminishing temperature difference between land and sea..."
