Hurricane Matthew approaching the east coast of Florida on Oct. 6, 2016.
Two atmospheric scientists explain how they weigh evidence such as ocean temperatures, wind speeds and other climate patterns to predict how many Atlantic hurricanes are likely to form this year.
The higher the plume, the bigger the problem.

When a bushfire rages so high it creates its own thunderstorm, it becomes a 'firestorm' - and makes life much more difficult for firefighters. We still have a lot to learn about what triggers them.

New study changes what we know about the pre-industrial atmosphere – and how we predict future climate change.
Ban on CFCs in aerosol sprays and refrigerants has led to a steady shrinking of the ozone hole.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.

While planes still emit too much carbon, they may also help the climate by ensuring clouds bounce more sunlight back into space.
CSIRO’s Birdsville station is one of several in Australia that monitors aerosols in our skies.
A leading NASA scientist has asked CSIRO to stay in its global network that monitors atmospheric dust and pollution. The data are vital to understand the effects on weather and climate.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
Bureau of Meteorology
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core.
Space research never stops and it seems neither do the surprises. On ABC Breakfast News I covered some huge results from the last few weeks. Be still my beating (magnetic) heart Earth’s magnetic field…
New Horizons continues to help unravel the icy dwarf planet’s secrets.

After last summer's Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here's some of what scientists have learned so far from that rich, slow cache.
