Meteorologists for the British government report that the concentration of carbon dioxide in the atmosphere - the leading cause of global warming - appears on track for one of the biggest annual increases since recordings began in the 1950s.
It's partly fuelled by the devastating wildfires raging across Australia.

The concentration of carbon dioxide in the atmosphere, the leading cause of global warming, appears on track for one of its biggest annual increases since recordings began in the 1950s.
Partly, according to researchers, due to the massive and devastating wildfires that have swept Australia for months.
The news comes from meteorologists with the British government.
It says that while manmade emissions, such as from cars and factories, have always represented the bulk of the concentration that it's also influenced by weather patterns.
About a fifth of that influence from weather this year will reportedly come from the fires.
Scientists have long warned that climate change increases the likelihood of wildfires, which in turn worsen climate change in a snowball effect.
This current season of fire in Australia has burned at least 38,000 square miles of territory.
That's about the size of the state of Kentucky.
