How Do You Ski if There Is No Snow?

Paul RacetteClimate, Economy

Imagine a ski resort whose chairlifts are in the lower reaches of mountains without decent snow. Or a scuba club whose reefs succumbed to warmer and stormier seas. Or a golfing hotel in a district where water shortages made it impossible to keep fairways green. Climate change is affecting the world’s tourist industry.

Uncertain times for climate change

Paul RacetteClimate

Research shows improving climate models and understanding will not necessarily reduce uncertainty in climate sensitivity and that a relatively small change in climate processes could lead to extreme climate sensitivity.

Wildfires move Canadian forests from sink to source

Paul RacetteClimate

Increase in frequency and size of fires affects carbon-absorption properties of boreal forests. “The recent several decades of wildfires are changing the boreal forest from a weak carbon sink – that is the forest and soil are accumulating carbon and helping offset rising atmospheric carbon dioxide concentration – to a weak carbon source,” Stith Gower of the University of Wisconsin … Read More

News: Massive California Fires Consistent With Climate Change

Paul RacetteClimate, Disasters

The catastrophic fires that are sweeping Southern California are consistent with what climate change models have been predicting for years, experts say, and they may be just a prelude to many more such events in the future – as vegetation grows heavier than usual and then ignites during prolonged drought periods.

A Global Search Engine For Geospatial Data

The TRMM satellite passed over Irene when it was a tropical storm on Aug. 21, 2011. Data collected with this orbit showed that Irene contained numerous powerful thunderstorms with TRMM's Precipitation Radar (PR) revealing that some thunderstorm towers near the center of the storm were reaching to heights above 15 km (~9.3 miles).

NOAA BuoyIf you’re a scientist or engineer cobbling together a geospatial project, say you’re trying to figure out how many people would be threatened by a tsunami in the Indian Ocean, a truism holds that you spend 80 percent of the time hunting down usable data. The data, when they exist at all, often are archived in incompatible formats, have varying degrees of accuracy and precision, and sometimes require a good deal of political savvy to find.

North Atlantic Slows on the Uptake of CO2

Further evidence for the decline of the oceans’ historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia (UEA).

Met Office

The United Kingdom’s Met Office is one of the world’s leading providers of environmental and weather-related services. Our solutions and services meet the needs of many communities of interest, from the general public, government and schools, through broadcasters and online media, to civil aviation and almost every other industry sector – in the UK and around the world. It is also home to the Hadley Centre for climate research.

Antarctic snowmelt progresses inland

Paul RacetteClimate

Using 20  years of data from satellite observations, NASA scientists have confirmed that snow has been melting further inland and at higher elevations in Antarctica. Warmer temperatures are probably responsible for these phenomena, says the team.
