In-depth: BP’s global data for 2017 shows record highs for coal and renewables Renewable energy grew by the largest amount ever last year, while coal-fired electricity also reached a record high, according to new global […]
Sea level rise due to Antarctic ice melt has ‘tripled over past five years’
Sea level rise due to Antarctic ice melt has ‘tripled over past five years’ The rate of sea level rise resulting from the melting of the Antarctic ice sheet has tripled over the past five years, according to new research from a global team of scientists. The study, published in Nature, finds that ice loss […]
World can limit global warming to 1.5C by ‘improving energy efficiency’
World can limit global warming to 1.5C by ‘improving energy efficiency’ It is possible to limit global warming to 1.5C and achieve many of the sustainable development goals without “negative emissions technologies”, a new study finds. The research suggests that improving energy efficiency – chiefly by saving on everyday energy use – could play a major […]
Global warming to date could ‘obliterate’ a third of glacier ice
Global warming to date could ‘obliterate’ a third of glacier ice The warming the world has already experienced could be enough to melt more than a third of the world’s glaciers outside Antarctica and Greenland – regardless of current efforts to reduce emissions. That is the stark conclusion of a new study, which analyses the […]
Acidification could leave oceans ‘uninhabitable’ for cold-water corals
Acidification could leave oceans ‘uninhabitable’ for cold-water corals The world’s oceans could become “uninhabitable” for cold-water corals by the end of the century as a result of ocean acidification, research suggests. Ocean acidification, which occurs as seawater takes up CO2 from the atmosphere, could threaten around 70% of cold-water coral living below 1,500 metres in […]
New study questions impact of ending fossil fuel subsidies
New study questions impact of ending fossil fuel subsidies Ending the world’s fossil fuel subsidies would reduce global CO2 emissions by 0.5 to 2.2 gigatonnes (Gt) per year by 2030, a new study says. The research, published by Nature, concludes that the removal of subsidies would lead to bigger emissions reductions in oil and gas […]
Long-term climate variability ‘could fall’ as the world warms
Long-term climate variability ‘could fall’ as the world warms Long-term climate variability is the range of temperatures and weather patterns experienced by the Earth over a scale of thousands of years. New research suggests it could fall as the world warms. A study using data taken from fossils and ice cores finds that long-term temperature […]
2017: Carbon Brief’s end-of-year review
2017: Carbon Brief’s end-of-year review As the year draws to a close, Carbon Brief takes a look at 2017’s top climate and energy stories through the medium of numbers… 49 countries For CO2 emissions to fall, they first have to peak. And research published this year suggests that this is already happening. The report, produced […]
Analysis: Why scientists think 100% of global warming is due to humans
Analysis: Why scientists think 100% of global warming is due to humans The extent of the human contribution to modern global warming is a hotly debated topic in political circles, particularly in the US. During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of […]
Analysis: Global CO2 emissions set to rise 2% in 2017 after three-year ‘plateau’
Analysis: Global CO2 emissions set to rise 2% in 2017 after three-year ‘plateau’ Over the past three years, global CO2 emissions from fossil fuels have remained relatively flat. However, early estimates from the Global Carbon Project (GCP) using preliminary data suggest that this is likely to change in 2017 with global emissions set to grow […]
The Carbon Brief Interview: Dr Katharine Hayhoe
The Carbon Brief Interview: Dr Katharine Hayhoe Dr Katharine Hayhoe is a professor in the department of political science at Texas Tech University and director of its Climate Science Center. She was a lead author on the Climate Science Special Report, part of the fourth US National Climate Assessment, which was published in early November […]
State of the climate: 2017 shaping up to be warmest ‘non-El Niño’ year
State of the climate: 2017 shaping up to be warmest ‘non-El Niño’ year Much of the year, though the summer Arctic minimum was only the eighth lowest on record. 2017 is also almost certain to be the warmest year without an El Niño event. When the effects of El Niño and La Niña are removed […]
Factcheck: Climate models have not ‘exaggerated’ global warming
Factcheck: Climate models have not ‘exaggerated’ global warming A new study published in the Nature Geosciences journal this week by largely UK-based climate scientists has led to claims in the media that climate models are “wrong” and have significantly overestimated the observed warming of the planet. Here Carbon Brief shows why such claims are a […]

Feeding the world: Can we preserve forests, go organic and eat meat?
Feeding the world: Can we preserve forests, go organic and eat meat? Credit: Jane Boles/Flickr It is possible to produce enough food to feed a growing population without another tree being felled, according to new research. But there’s a catch. The only way to guarantee enough food in 2050 is if the world turns vegan, […]
