In recognition of Earth Day on April 22, 2013, the USGS is highlighting a few aspects of climate change. The effects of climate change have been documented in the United States and around the world. These effects pose challenges and risks to our landscapes, natural and agricultural resources, wildlife, the economy, and the public health and safety of our communities.
USGS scientists seek to measure, document, and understand the changes that have occurred in the Earth’s recent and distant past, and then interpret and communicate the causes and consequences of those changes.
USGS expertise is diverse, for example, seeking to improve our understanding of climate change effects on wildlife and ecosystems; risks to coastal communities associated with sea-level rise, coastal erosion, and storms; how carbon circulates across the globe, including how and where it can be stored in ecosystems and subsurface rocks; and changes in water resource availability, including the effects of droughts and floods.
The USGS makes data free and easily accessible to the public, resource managers, policymakers and other decisionmakers. As the nation’s earth-science agency, the USGS provides unbiased scientific information that serves as a foundation for sound decisions as we face these climate change challenges.

Slideshow: Faces of Climate Change
The following slideshow highlights examples of climate change impacts to variety of places and people across the globe. This aims to give a glimpse of the many faces of climate change.
Video Series: America’s Climate Change Questions
America has questions about climate change, and the USGS is providing answers through a video series called, Climate Connections.
In these videos, USGS scientists are engaging in conversations and addressing questions from across the nation. The USGS has authoritative and science-based information to address a wide range of topics related to climate change.
There are six episodes from Colorado, the District of Columbia, Glacier National Park, Puerto Rico, and North and South Carolina.
Hyperlinks and details to each episode are provided below.
