"The 2023-2025 mean is +1.5°C relative to 1880-1920. We project a #global #temperature record of +1.7°C in 2027."
Let's find out why we are #accelerating #climatechange instead of reversing it!

More than 60 scientists issue dire warning that the Earth is careening toward catastrophe: 'Things are all moving in the wrong direction'

"We're seeing some unprecedented changes, and we're also seeing the heating of the Earth and sea-level rise accelerating as well.“

dear #climatescience on bluesky.
i'm gonna say this as nicely as possible. NO ONE gives a fuck anymore about whether #climatechange is #accelerating exponentially or just increasing very steeply. things people care about nowaday: mental survival, not being #deported, not falling into #poverty, not dying of heat stroke.
who are you doing this for? bc to me it seems you and your respective fanbase do it purely for ego (and maybe US #university funding).
you are losing people.
The rate at which atmospheric CO2 is increasing is now outpacing the pathways set out by the Intergovernmental Panel on Climate Change (IPCC) that limit global warming to 1.5C.
The third working group report of the #IPCC’s sixth assessment report (#AR6), published in 2022, presented a set of seven “illustrative pathways” that highlight how different mitigation choices across major economic sectors translate into future #GreenhouseGas #emissions and global temperatures.
In the three most-ambitious pathways, #GlobalWarming has a 50% chance of either staying below 1.5C, or overshooting it by only 0.1C (for up to several decades) before then returning to below 1.5C.
Yet, not only are atmospheric #CO2 concentrations still rising, the rate of rise is #accelerating.
The build-up of CO2 in the #atmosphere has been monitored at the #MaunaLoa observatory in #Hawaii since 1958.
As illustrated by the iconic #KeelingCurve below, the increase has been accelerating over the decades (blue line) due to ongoing emissions of CO2 from burning #FossilFuels and changing land use.
So while the curve needs to rapidly bend in the other direction to hold warming to 1.5C (light red line), the rate of rising CO2 marches onwards and upwards.

Ocean-surface warming has more than quadrupled since the late-1980s, study shows
The rate of #ocean #warming has more than quadrupled over the past four decades, a new study has shown. Ocean temperatures were rising at about 0.06°C per decade in the late 1980s, but are now increasing at 0.27°C per decade.
Published 28 January 2025 in Environmental Research Letters, the study helps explain why 2023 and early 2024 saw unprecedented ocean temperatures.
This #accelerating ocean warming is driven by the Earth's growing energy imbalance—whereby more #energy from the sun is being absorbed in the Earth's system than is escaping back to space. This imbalance has roughly doubled since 2010, in part due to increasing #GreenhouseGas concentrations, and because the #Earth is now reflecting less sunlight to space than before.
Global ocean temperatures hit record highs for 450 days straight in 2023 and early 2024. Some of this warmth came from #ElNiño, a natural warming event in the Pacific.
