Burning wood releases more CO2 than gas, oil and even coal, so to make it climate neutral we need an increase in forests

With snow on the ground, many people will have been huddling around a wood fire, but researchers are questioning if wood burning is really climate neutral. Burning wood is not CO2 free; it releases carbon, stored over the previous decades, in one quick burst. For an equal amount of heat or electricity, it releases more CO2 than burning gas, oil and even coal, so straight away we have more CO2 in the air from burning wood. This should be reabsorbed as trees regrow. For logs from mature Canadian woodland, it could take more than 100 years before the atmospheric CO2 is less than the alternative scenario of burning a fossil fuel and leaving the trees in the forest.

Deal with Eastern Australia Agriculture raises, which was done without a tender, raises questions over taxpayer value

One of Australia’s largest cotton companies, Eastern Australia Agriculture (EAA), sold water rights to the federal government in July last year for $79m and then booked a $52m gain on the sale.

The deal, which was done without tender, will raise questions about whether the government paid over the odds for the water in southern Queensland.

A new study finds that waiting 5 extra years to peak carbon pollution will cost 20 cm sea level rise

A new study published in Nature looks at how much global sea level will continue to rise even if we manage to meet the Paris climate target of staying below 2°C hotter than pre-industrial temperatures. The issue is that sea levels keep rising for several hundred years after we stabilize temperatures, largely due to the continued melting of ice sheets in Antarctica and Greenland from the heat already in the climate system.

The study considered two scenarios. In the first, human carbon pollution peaks somewhere between 2020 and 2035 and falls quickly thereafter, reaching zero between 2035 and 2055 and staying there. Global temperatures in the first scenario peak at and remain steady below 2°C. In the second scenario, we capture and sequester carbon to reach net negative emissions (more captured than emitted) between 2040 and 2060, resulting in falling global temperatures in the second half of the century.

Woodland Trust records show more evidence that spring is arriving earlier in the UK

Winter in the UK has become a landscape of yellow hawthorn, the orange flash of red admiral butterflies, blackbirds nesting, and bumblebees feeding on mauve chives, pink valerian and lavender.

Before the white-out of snow which covered much of the country on Wednesday, reports by the Woodland Trust charity showed yet more evidence that spring is arriving earlier and earlier.
