Oceans Are 'Spiking a Fever' With Record Heat Waves

The number of heat waves affecting the planet’s oceans has increased sharply, scientists have revealed, killing swathes of sea life like “wildfires that take out huge areas of forest.” The damage caused in these hotspots is also harmful for humanity, which relies on the oceans for oxygen, food, storm protection and the removal of climate-warming carbon dioxide the atmosphere, they say.

Burning wood - not as cosy as it seems

Smoke from home fires in winter can be smelt across our towns, causing irritation and annoyance to some, reducing visibility, and frequently causing air quality to exceed the National Environmental Standard. Although we don’t monitor smog directly, the levels of smoke are indicated by networks of air quality monitors operated by regional councils.
