Haze from Northern California wildfires has drifted as far east as Philadelphia. Wildfire smoke contains many potentially toxic substances, so anyone exposed to it should take basic precautions.

The dry, hot, downslope Santa Ana winds of Southern California fan late fall wildfires that have largely traveled through – and are fueled by – homes and other structures.
Waves lap against the shore on the south coast of England and the North coast of France – but the answer to this puzzle is in the wind and the land, not the waves themselves.
A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.

Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.

The US was hit by a ‘bomb cyclone’ last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.

New modelling suggests that Australia could use renewable energy to hit its 2030 emissions reduction targets, without it costing any more overall than maintaining the status quo.
Meteorology researchers across the country are prepping experiments for the mini-night the eclipse will bring on August 21 – two minutes and 36 seconds without the sun in the middle of the day.
