How did elephants evolve such a large brain? Climate change is part of the answer

Elephants have long captivated our attention, partly because of their sheer size and majesty. But we’re also struck by their complex behaviour. In some ways, we’re fascinated because this behaviour echoes our most humane feelings. For instance, elephants have repeatedly been observed using tools and grieving their dead.

Seismic tracks from oil exploration show clearly from the air.

Methane emissions from oil and gas exploration are under-reported

Wetlands in Canada’s boreal forest contain deep deposits of carbon-rich soils, made up of decomposed vegetation (peat) that has accumulated over thousands of years. Globally, peatlands store twice as much carbon as all of the world’s forests combined. Protecting this carbon store is critical in the fight against climate change.

Climate champion Greta Thunberg to set sail for Americas on zero-carbon trip

Swedish teen activist Greta Thunberg is taking a year off school to pursue her campaign to curb global warming in the Americas, which she will reach by sailboat on a transatlantic voyage. She will travel from Britain to the United States on a racing boat fitted with solar panels and underwater turbines that produce electricity onboard, making the journey zero-carbon.

Increasing danger of ‘unexpected implications’ as climate risks converge

If India’s water-short farmers were to adopt more efficient methods of irrigation, cutting evaporation from their fields, farmers in East Africa might see less rainfall – and worsening drought – within five years, scientists have warned.

As funding for Resilient Cities ends, plans to counter risks from climate & social change continue

More than 70 cities that are part of the 100 Resilient Cities (100RC) network, set up in 2013, have crafted “resilience strategies” that include about 3,500 activities designed to combat shocks and stresses – everything from floods to an influx of refugees.

Could a simple glue be the solution to carbon capture at power stations?

Is glue the answer to climate change? Researchers at the Energy Safety Research Institute (ESRI) at Swansea University have proven that it could certainly help. They have developed a new material capable of capturing the greenhouse gas carbon dioxide (CO2) with the key ingredient being a common epoxy resin you probably have at home.

Pellet makers say they use only lumber mill waste, treetops and limbs, and crooked trees to produce wood pellets. Industry critics argue that companies are increasingly clear-cutting forests to meet growing demand. Losing standing forests means losing natural carbon sinks, biodiversity and protection from storms and floods. Photo credit: USDAgov on Visual Hunt / CC BY

UK’s net-zero emissions 2050 pledge undermined by biomass energy loophole

The United Kingdom and the European Union are setting goals to achieve net-zero carbon emissions by 2050. But that declaration is deeply flawed, analysts say, due to a long-standing United Nations carbon accounting loophole that turns a blind eye toward the conversion of coal burning power plants to burning wood pellets.
