Long-term sea-level rise implied by 1.5 degree and 2 degree Celsius warming levels
Some further sea-level rise is already inevitable, with the best possible case being a rise of 59 cm above 2000 levels over the twenty-first century following a hypothetical reduction of emissions to zero by 2016. However, the study underlines the significant impact that different mitigation scenarios will have in determining the extent and rate of sea-level rise by 2100, but even stronger by 2300.
A scenario in which global mean temperature is allowed to increase to 3 degrees Celsius above pre-industrial levels, for example, would involve sea-level rise of between 2 and 4 m over the coming three centuries, while ambitious mitigation targets which limit warming to 1.5 degrees could substantially slow down the rate at which it occurs, resulting in a rise of 1.5 m by 2300, and possibly less than that.
A number of uncertainties are associated with these projections, particularly given the difficulty of predicting the behaviour of the Greenland and Antarctic ice sheets, precise models of which are still being developed. What is clear is that a commitment to multi-meter sea level rise after 2100 can be avoided by immediate action to cut greenhouse-gas emissions.
Carbon capture and storage could unleash 86 billion tonne carbon bomb
A new analysis finds reliance on carbon capture and storage could release an extra 86 billion tonnes of greenhouse gases into the atmosphere between 2020 and 2050.
Projected warming almost unchanged for two years as governments push false solutions over climate action
Despite their promises, governments have not taken enough action to drive down warming projections, with some instead turning to false solutions such as carbon capture and storage to continue the world's reliance on fossil fuels, according to the Climate Action Tracker's annual warming update.
Oil and gas majors could have paid for their share of climate loss and damage and still earned 10 trillion USD: new report
Global climate damages from emissions associated with the top 25 oil and gas ‘carbon majors’ between 1985 and 2018 are estimated at 20 trillion USD compared to the 30 trillion USD they earned over the same period, according to a new report released today by international think tank Climate Analytics.
A 1.5˚C pathway for the Philippines power sector entirely feasible: analysis
With the right international funding and policies in place, the Philippines could transition its’ power sector to near-100% renewable energy without compromising on the costs of electricity, reducing its reliance on expensive imports of both coal and gas, and creating up to a million jobs by 2050.
State of Climate Action report finds progress lags on every measure except EV sales
Global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator — except electric passenger car sales — lagging significantly behind the pace and scale that is necessary to address the climate crisis.
Governments plan to produce double the fossil fuels in 2030 than the 1.5°C warming limit allows
The Production Gap Report finds governments plan to produce around 110% more fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, and 69% more than would be consistent with 2°C.
Beetaloo fracking and Middle Arm emissions wildly underestimated: analysis
An independent analysis of the projected emissions from the Northern Territory's proposed Beetaloo Basin gas fracking project — and the associated Middle Arm LNG precinct in Darwin Harbour — has found they've been gravely underestimated, as have the availability of offsets to deal with them.
Comic artists respond to the climate crisis
Three leading comic creators have collaborated with the Horizon Europe project, CONSTRAIN, to develop comics exploring the climate change challenge.

Changes to the jet stream could trigger simultaneous crop failures impacting global food security
This new study finds that the jet stream – air currents in the upper atmosphere – can synchronise extreme weather caused by climate change, resulting in crop failures in multiple countries at the same time.
