Fire alarm

FIRE ALARM 

Wildfires can cause devastation and are also to blame for more than a quarter of greenhouse gases being released into the atmosphere. Satellites play a key role in mapping landscape scarred by fire – but the Copernicus Sentinel-2 mission has revealed that there are more fires than previously thought.


COAL DEALER 

Methane emissions from coal mining in China have risen despite stricter government regulations that aimed to curb the greenhouse gas, satellite data shows. China’s methane emissions rose by 1.1m tonnes a year between 2010 and 2015. This could account for up to a quarter of the rise in methane emissions seen globally over that period, the study finds.


TESTING THE WATERS 

Scientists from ANU have used new space technology to predict droughts and increased bushfire risk up to five months in advance.They used data from multiple satellites to measure water below the Earth's surface with unprecedented precision, and were able to relate this to drought impacts on the vegetation several months later.


R-CHITECURE 

The language R was first created by statisticians in the early 1990s, and gets its name from the first letter of their first names – Ross Ihaka and Robert Gentleman – but also as a play on the S programming language, on which R is based. Diana Sinto wrote a comprehensive article on linking spatial analysis across disciplines with R.


CHICAGO SNO'HARE 

With the weather in Chicago finally warming up a bit, we are looking back at some of the imagery we captured of the snow last week. Here's Chicago's O'Hare International Airport - you can just make out the planes on the runway!
