Experts say no sign of slowdown in long-term warming trend
By Bob Berwyn
The average global temperature for 2015 was the warmest since record-keeping started in 1880, breaking the mark set last year by a full quarter degree, according to the latest climate update from NASA and NOAA.
Discussing the new temperature record in a telephone conference call, experts with the two agencies said 2016 could be hotter yet because of warmth stored in the oceans. There’s no sign at all that the long term global warming trend will slow down any time soon, said NASA researcher Gavin Schmidt.

New NASA website features daily deep space views of Earth
A high-tech space camera on a satellite orbiting 1 million miles away is giving Earthlings a daily view of the planet via a new NASA website. The images gathered by the Deep Space Climate Observatory (DSCOVR) enable the world to see images of the full, sunlit side of the Earth every day.

New Horizons mission a big step in exploration of solar system
FRISCO — After a 10-year, 3 billion mile voyage across the solar system, NASA’s New Horizons spacecraft flew within 8,000 miles of Pluto today — the first-ever space mission to explore a world so far from Earth.
“The exploration of Pluto and its moons by New Horizons represents the capstone event to 50 years of planetary exploration by NASA and the United States,” said NASA Administrator Charles Bolden. “Once again we have achieved a historic first. The United States is the first nation to reach Pluto, and with this mission has completed the initial survey of our solar system,” Bolden said.
Federal officials also touted other NASA space efforts, including the Kepler mission to identify Earth-like planets around stars other than our own; and the DSCOVR satellite that soon will be beaming back images of the whole Earth in near real-time from a vantage point a million miles away.

NASA and partners to track developing algal blooms from space
FRISCO — As global warming threatens to make toxic algal blooms more frequent and more intense, NASA, NOAA, the EPA and the U.S. Geological Survey have teamed up to try and develop an early warning system based on satellite data.
Algal blooms are a global environmental problem. They pose a health risk to people and animals and threaten drinking water supplies. In the United States, the cost of freshwater degraded by harmful algal blooms is estimated at $64 million annually. In August 2014, officials in Toledo, Ohio, banned the use of drinking water supplied to more than 400,000 residents after it was contaminated by an algal bloom in Lake Erie.
New NASA visual helps trace path of greenhouse gases
FRISCO — In a way, addressing global warming is like fighting a ghost. How do you tackle odorless and colorless heat-trapping gases like carbon dioxide and methane?
NASA, the government agency that literally has the best global perspective on climate change, has just released a new computer generated animation that help show the source of greenhouse gases and how they disperse around the planet. Continue reading “Psst! Wanna see some carbon dioxide?”→
