Scientists stress the need for climate policy to focus not on this century but on the inescapable impacts of greenhouse gas emissions over the next 10,000 years.

As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of Kampung Kalihi, the sarong she is weaving to sell locally will provide extra...
Do the same rules that govern human attraction also apply to our choices of fruit and vegetables? Plenty of evidence suggests we do look for similar traits in both people and produce, and our perceptions of food are clearly affected by what
The narrative around renewable energy sources is typically framed almost entirely in terms of their contribution to reducing carbon emissions and thereby providing a means to tackle climate change.
Science can now make energy by building immense wind turbine blades and filtering carbon from the air, but the challenge is commercial viability.
Speaking at a law school last week, Chief Justice John Roberts complained that sharp partisan criticisms of the Supreme Court have led the public to believe that it is just another political branch of government.
By many accounts, the spread of solar power is unstoppable. Costs continue to fall at a blistering pace, solutions to give consumers a solar-powered home without needing to connect to the grid for back-up power are emerging, and even the
When you cut and burn a tropical forest, you’re left with a barren plain of cracked red mud, incapable of supporting life – the opposite of the teeming, hyperdiverse array of life that was destroyed. Once the trees are gone, the nutrients wash away and the soil degrades into a dense, brick-like layer so hardened that plant roots can’t get through it.
New research suggests that fertilising oceans with iron to increase the growth of algae that absorb carbon dioxide is not the hoped-for answer to reducing global warming.
New global coalition says food that fails to reach consumers or is dumped as waste could instead save lives and cut greenhouse gas emissions.
Call for governments to give financial backing for technology that could help save the world from overheating by preventing CO2 escaping into the atmosphere.
Human society without fire is unthinkable. But a new book says we need to think of a world where fire gives way to electricity.
The international community has been negotiating on climate change since 1989, but the Paris Agreement marks a real step forward. It aims to accelerate a move away from fossil fuels to mitigate global warming and to help vulnerable countries adapt to the effects of climate change, and reflects a clear recognition of the urgency of the task.
Wind and solar power are a way to reduce carbon emissions but these generation sources are dependent on the vagaries of the weather, which means neither wind nor solar can produce electricity on-demand at all hours of the day.
Renewable energy could supply Russia and Central Asian countries with all the electricity they need by 2030 − and cut costs significantly at the same time.
The environmental and nutrient impact of our food choices had been on my mind for several weeks when a year-old article in the Telegraph recently came to my attention, prompting me to assemble the thoughts that had been gradually coalescing.
From turning carbon dioxide into a fuel to enabling cars to run on water, scientific researchers worldwide are unlocking the potential of new energy sources.
Second-generation biofuel made from natural grass species challenges ethanol derived from maize crops as the US seeks to reduce its fossil fuel use.
Throughout 2015, I had a hard time explaining my feeling about the Paris climate talks. Friends and allies would excitedly ask me if I was going and I’d force a smile and explain that no, I had been to enough United Nations climate meetings.
For a reasonable chance of keeping warming under 2℃ we can emit a further 865 billion tonnes of carbon dioxide (CO2). The climate commitments to reduce greenhouse gas emissions to 2030 are a first step, but recent analyses show they are not enough.
Any long-term solution will require “decarbonizing” the world energy economy – that is, shifting to power sources that use little or no fossil fuel.
