Consistent carbon pricing is a key element in the fight against climate change.
A man wears a scarf to defend himself from New Delhi’s smog.
India's capital New Delhi has been plunged into smog, a year after suffering a similar crisis. Without an end to crop burning, the problems with smog will only continue.
A medium-size passenger jet burns roughly 750 gallons of fuel per hour.
Scientists have engineered sugarcane to increase its oil content and are developing renewable jet aircraft fuel from the oil. The engineered sugarcane could become a valuable energy crop.
Plastic pollution: discarded plastic bags are a hazard to marine life.
Tonnes of plastic end up in the ocean each year, but a switch away from petroleum-based products to bio-derived and degradable composites could lessen marine pollution.

The failed attempt to reinstate land clearing regulations in Queensland has prompted 'panic clearing', pushing Australia into the global top-ten deforesters.
Climate fight: a traditional Fijian warrior poses at the UN climate summit in Bonn.
To many people, island nations such as Tuvalu, Kiribati and the Marshall Islands are synonymous with climate catastrophe. But prophesies of doom aren't all that helpful.
Transportation is the biggest contributor to greenhouse gases by sector. Converting the U.S. fleet to cleaner electric vehicles would likely take decades.

What if the world really got serious about meeting global climate goals? Doing the math on current emissions and the pace of energy transitions shows how quickly fossil fuels need to be phased out.
The intensity of heavy downpours in Houston has increased dramatically since the 1950s, leading some people to argue the city’s disaster planning and infrastructure are not up-to-date.

Although climate change threatens the world's small island nations, many can find ways to adapt and preserve their homes and cultures – especially if wealthy countries cut emissions and provide support.
Everyone knows that plastic waste is an environmental problem. So let's get creative with it.
The growth in global carbon emissions has resumed after a three-year pause.

After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
The well-being of pollinators like bees have a direct impact on our lives.

Pollination in South Africa's ecosystems is extremely complex. However new advances such as pollen metabarcoding help us understand interactions between pollinators and pollen.
Laiap, to the west of the site of the now-disappeared Nahlapenlohd.
In 1850, the Micronesian island of Nahlapenlohd was the scene of Pohnpei state's first battle involving cannons and muskets. Less than two centuries later, it has sunk beneath the waves.
