Listen Current: Katrina 10 Years Later

Listen Current

September 4, 2015  --  It’s been 10 years since Hurricane Katrina flooded New Orleans. At the time then President George W. Bush and his administration were widely criticized for their slow response to the flooding. But on the 10 year anniversary Bush was invited back to visit the city again. His tour sparked mixed reactions from residents who still feel they were let down by the federal government's response to the massive disaster. Use this story to discuss this anniversary and the local reactions to the federal response.

PAESTA Podcast Series: Episode 4 - What is a Watershed?

You Asked, We Answered!

Transcript for the podcast

We all live in a watershed – think of it as your ecological address, and no matter where you are on land, any water that falls in that same location has a drainage destination determined by elevation and landforms. A watershed is an area of land where the surface water (including lakes, streams, reservoirs, and wetlands) and the underlying groundwater flows from a higher to lower elevation. Streams and rainfall within a watershed will typically drain to a common outlet, such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. The word watershed is sometimes used interchangeably with drainage basin or catchment.

PAESTA Podcast Series: Episode 3 - How do Scientists Measure Rainfall?

You Asked, We Answered!

Transcript for the podcast

Many schools will have a rain gauge installed, where students can measure and record the amount of rain that falls each day. But scientists do not measure precipitation on the ground – they measure precipitation from space, using a combination of active and passive remote-sensing techniques, improving the spatial and temporal coverage of precipitation observations on a global scale.  You see, reliable ground-based precipitation measurements are difficult to obtain because most of the world is covered by water, and many countries do not have precise rain measuring equipment (such as rain gauges and radar). Precipitation is also difficult to measure because precipitation systems can be somewhat random and can evolve very rapidly. During a storm, precipitation amounts can vary greatly over a very small area and over a short time span.

2014 State of the Climate: Highlights

NOAA

International report confirms: 2014 was Earth’s warmest year on record  --  Climate markers continue to show global warming trend

In 2014, the most essential indicators of Earth’s changing climate continued to reflect trends of a warming planet, with several  markers such as rising land and ocean temperature, sea levels and greenhouse gases ─ setting new records.  These key findings and others can be found in the State of the Climate in 2014 report released online today by the American Meteorological Society (AMS).
