A new study finds that the mining and processing of the metal critical to EV batteries and renewable energy storage projects depletes and contaminates surface water, often in already vulnerable communities.

Scientists now fear that there is little more than five years left to prevent irreversible climate damage and stark changes to the Earth’s weather patterns from global carbon emissions, Minister for Climate Eamon Ryan has warned.

Melting of ice is slowing planet’s rotation and could disrupt internet traffic, financial transactions and GPS

Breathless reporting on when the present global heat anomaly will begin to fall is understandable, given heat suffering around the world. However, fundamental issues are in question and a reflection on time scales is in order, for the sake of understanding ongoing climate change and actions that need to be taken.

Warning after intensification of storm aided by unusually hot ocean waters in much of Beryl’s path. Hurricane Beryl, which slammed into Texas on Monday after wreaking havoc in the Caribbean, was supercharged by “absolutely crazy” ocean temperatures that are likely to fuel further violent storms in the coming months, scientists have warned.

Monthly global surface air temperature anomalies (°C) relative to 1850–1900 from January 1940 to June 2024, plotted as time series for all 12-month periods spanning July to June of the following year. The 12 months from July 2023 to June 2024 are shown with a thick red line, while all other 12-month periods are shown with thin lines shaded according to the decade, from blue (1940s) to brick red (2020s).

A carbon bomb is any fossil fuel extraction project that will generate more than one gigatonne of carbon dioxide (1GtCO2) over its remaining life.

Offsetting allows corporations to increase emissions, while getting credit for pseudo-reductions elsewhere

Economic growth allows the few to grow ever-wealthier. Ending poverty and environmental catastrophe demands fresh thinking

Mainstream media are ignoring a scientist who is whistleblowing the climate profession. During the five years since new kinds of activism brought the climate issue into the headlines like never before, the topic has more clearly become one where people respond due to their preexisting worldviews. It’s not just believers and sceptics, but there are those who think technology can save us, those who think it’s too late; those who think the science is clear, others who think it is open; those who believe humans will muddle through and those predicting human extinction. Climate scientists themselves now range from those emphasizing ‘we can do this’ to those that express their grief and outrage by gluing themselves to buildings. Meanwhile, misleading narratives are amplified by a variety of vested interests, including fossil fuels, nuclear, and clean tech. Climatologist Dr Wolfgang Knorr is an unusual voice in this cacophony because he has been ‘blowing the whistle’ on the climate science itself and how it is being

Scientists warn of ‘scary’ feedback loop in which fires create more heating, which causes more fires worldwide

Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit

Since the Paris Agreement in 2016, the world’s 60 largest private banks financed fossil fuels with USD $6.9 trillion. Nearly half – $3.3 trillion – went towards fossil fuel expansion. In 2023, banks financed $705 billion in fossil fuel financing with $347 billion going to fossil fuel expansion alone.

With current policies the Earth is on track to a warming of around 3 °C above preindustrial temperatures, a level of heat our planet has not seen for millions of years. Ecosystems, human society and infrastructure are not adapted to these temperatures. Due to non-linear effects, the impacts will be much more severe than just three times as bad as after 1 °C of warming. Land areas will continue to warm much more than the global average, many regions twice as much or even more. Extreme heat will become far more frequent and a major cause of human mortality, making large parts of the tropical land area essentially too hot to live. In addition, extreme rainfall and flooding, droughts, wildfires and harvest failures will increase in frequency and severity. The destructive power of tropical cyclones will also increase. Sea-level rise will accelerate further, and the destabilization of ice sheets will commit our descendants to loss of coastal cities and island nations. The risk of crossing devastating and irreversib

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC). Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activit

If currently implemented policies are continued with no increase in ambition, there is a 90% chance that the Earth will warm between 2.3°C and 4.5°C, with a best estimate of 3.5°C.

This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.

Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN) and published via Oxford University Press, reveals extensive networks impeding climate action within the region and surrounding states. In Italy and Germany, far-right networks spread misinformation by questioning climate science’s validity, while in Spain and the UK, blame-shifting and deflecting responsibility for climate action are common. European-based fossil fuel industries, like Shell, engage in greenwashing, by framing gas as a ‘bridging technology crucial for the energy transition’, delaying genuine progress.

Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN), is the first book to document the development and nature of climate obstruction activities across Europe, which are efforts to deliberately slow or block climate action. Climate obstruction strategies range from outright denial to more subtle forces of delay and the spread of disinformation
