Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances. The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook. This new report – based on analysis of the production records of around 15 000 oil and gas fields around the world – explores the implications of accelerating decline rates, growing reliance on unconventional resources, and evolving project development patterns for the global oil and gas supply landscape, for energy security and for investment. It also provides regional insights

The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the century under future climate change, as this requires long climate model simulations which are not always available. Here, we analyze targeted climate model simulations done with the Community Earth System Model (CESM) with the aim to develop a physics-based indicator for the onset of an AMOC tipping event. This indicator is diagnosed from the surface buoyancy fluxes over the North Atlantic Ocean and is performing successfully under quasi-equilibrium freshwater forcing, freshwater pulse forcing, climate change scenarios, and for different climate models. An analysis consisting of 25 different climate models shows that the AMOC could begin to collapse by 2063 (from 2026 to 2095, to percentiles) under an intermediate emission scenario (SSP2-4.5), or by 2055 (from 2023 to 2076, to percentiles) under a high-end emission scenar

As civilization advanced, humans developed tools that allowed us to shield ourselves from the natural cycles that once defined our lives. Fire helped us escape the cold. Irrigation let us shape landscapes around our needs. Walls and weapons kept predators at bay. Over time, these inventions accumulated into infrastructure, then ideology. The more protected we became, the more separated we felt...

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global

In a previous post, I defined this graph as “the most amazing graph of the 21st century.” It shows how the US oil production restarted growing in 2010, picking up speed and surpassing the historical record of the “Hubbert Peak,” which took place in 1970. It overcame the dip caused by the Covid pandemic and, two years after my first post on this subject, it keeps growing.

California has sued five of the largest oil and gas companies in the world, alleging that they engaged in a 'decades-long campaign of deception' about climate change and the risks posed by fossil fuels.

Permafrost and glaciers in the high Arctic form an impermeable ‘cryospheric cap’ that traps a large reservoir of subsurface methane, preventing it from reaching the atmosphere. Cryospheric vulnerability to climate warming is making releases of this methane possible. On Svalbard, where air temperatures are rising more than two times faster than the average for the Arctic, glaciers are retreating and leaving behind exposed forefields that enable rapid methane escape. Here we document how methane-rich groundwater springs have formed in recently revealed forefields of 78 land-terminating glaciers across central Svalbard, bringing deep-seated methane gas to the surface. Waters collected from these springs during February–May of 2021 and 2022 are supersaturated with methane up to 600,000 times greater than atmospheric equilibration. Spatial sampling reveals a geological dependency on the extent of methane supersaturation, with isotopic evidence of a thermogenic source. We estimate annual methane emissions from prog

Longtermism is a perspective that there is a moral reason to consider how the actions and decisions we take today affect the lives of huge numbers of future people.
At the Hay Festival, BBC Future assembled a panel of thinkers to discuss one of the most pressing questions of our time: how to tackle society’s habit of “short-termism”.
Behind the headlines about billionaire jaunts into space, there's a deeper motivation – the belief that spreading into the cosmos will save humanity's future. How did this idea emerge?

Long before the current political divide over climate change, and even before the U.S. Civil War (1861-1865), an American scientist named Eunice Foote documented the underlying cause of today’s climate change crisis. The year was 1856. Foote’s brief scientific paper was the first to describe the extraordinary power of carbon dioxide gas to absorb heat – the driving force of global warming. Carbon dioxide is an odorless, tasteless, transparent gas that forms when people burn fuels, including coal, oil, gasoline and wood.
What else is new? Hotspots are getting hotter. The major hotspot in April stretched from Iraq to India and Pakistan, and toward the northeast through Russia (Fig. 1). Temperature exceeded 45°C (113°F) in late April in at least nine Indian cities,[1] on its way to 50°C (122°F) in Pakistan in May,[2] where a laborer says “It’s like fire burning all around” and a meteorologist describing growing heatwaves since 2015 says “The intensity is increasing, and the duration is increasing, and the frequency is increasing.” Halfway around the world, Canada and north-central United States were cooler than their long-term average, but people in British Columbia and northwest United States remember being under their own record-breaking hotspot last summer.

It took me a while but I finally digested the 107 pages of Chapter 5: Demand, services and social aspects of mitigation in the last IPCC report on Mitigation of climate change. This chapter is worth the read if only because it’s the first one fully dedicated to demand-side strategies. What I find remarkable is its conceptual width, including a few ideas that are usually considered too radical in these kind of venues. But just like the rest of the report, it is long and – as academic writing too often is – full of abstract jargon and somnolent prose. What I want to do in this article is to explain why Chapter 5 is more radical (in the good sense of the term) that you may think.
