This is the first of nine lessons in the "Visualizing and Understanding the Science of Climate Change" website. This lesson is an introduction to Earth's climate and covers key principles regarding Earth's unique climate, atmosphere, and regional and temporal climate differences.

This webinar will examine how variations in the tropical Pacific can affect high-latitude regions such as Alaska.

One of ENSO’s most important influences is to the Indian Monsoon—the large-scale circulation pattern that brings the Indian subcontinent the vast majority of its yearly rainfall. And while La Niñas tend to increase monsoon rainfall, the monsoon’s relationship with El Niño can be a little more complicated.  

Regional conference for planners, decision-makers, & educators on how communities can be more resilient to severe weather & climate impacts.

This beautifully filmed and produced video describes the changes that global warming is already bringing to Northern Canada and Greenland. Local people describe changes to ecosystems, impacts on culture and life styles, and the challenges of melting permafrost. Ship captains describe changes in navigational channels and fjords. Scientists describe changes in albedo and permafrost, as well as increased pollution transported from outside the Arctic (the Grasshopper effect).

Climate Change 2013: The Physical Science Basis

On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.

Assessment of Climate Change in the Southwest United States

A part of the 2013 U.S. National Climate Assessment, this book gives an overview of the past, present, and projected future of the southwest region's climate, emphasizing new information and understandings since publication of the previous national assessment in 2009.  It examines what climate and climate change mean for the health and well-being of human populations and the environment.

AgroClimate

An open-source suite of tools developed specifically for farmers and ranchers in the southeastern U.S. Tools available can help growers plan for certain types of crop disease, crop yields, climate and drought risks, growing degree days, greenhouse gas emissions, and water usage.
