Climate change: Trees 'most effective solution' for warming

Researchers say an area the size of the US is available for planting trees around the world, and this could have a dramatic impact on climate change.

Planting trees could have a huge impact on the mitigation of climate change.

The study shows that the space available for trees is far greater than previously thought, and would reduce CO2 in the atmosphere by 25%.

The authors say that this is the most effective climate change solution available to the world right now.

But other researchers say the new study is "too good to be true”.

Heatwaves linked to an increase in Australian suicide rates

Heatwaves and high temperatures can have a dramatic impact on people’s physical health. We only have to look at the increases in emergency department admissions during recent heatwaves to know that.

A spike in suicides linked to spikes in heat.

But not many people realise that high variations in temperatures can also impact our mental health.

For my PhD thesis I studied the socio-environmental drivers of suicide rates in Australia from 1986 to 2005. I found that sudden spikes in average temperatures can be attributed as a risk factor for suicide in some cities.
