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.

Durability of #CarbonDioxide removal is critical for stabilizing temperatures

The world is emitting over 40 gigatons of #CO2 per year, contributing to an #accelerating warming of the planet. The world needs to cut #emissions rapidly to be remotely on track to meet our #ParisAgreement goals of limiting warming to well-below #2C, and we should be spending the vast majority (>95%) of our resources today on reducing emissions.

Modern cars have been called “smartphones with wheels,” because they are connected to the internet and packed with sensors and cameras.

#LexisNexis #Risk #Solutions, a data broker, has traditionally kept tabs for insurers on drivers’ moving violations, prior insurance coverage and accidents.

When Romeo Chicco requested his LexisNexis file, it contained details about 258 trips he had taken in his Cadillac over the past six months.

His file included the distance he had driven, when the trips started and ended, and an accounting of any #speeding and #hard #braking or #accelerating.

The data had been provided by #General #Motors — the manufacturer of his Cadillac.

In a complaint against General Motors and LexisNexis Risk Solutions filed in the U.S. District Court for the Southern District of Florida, Mr. Chicco accused the companies of violation of privacy and consumer protection laws.

The lawsuit follows a report by The New York Times that, unknown to consumers, automakers have been sharing information on their driving behavior with the insurance industry, resulting in #increased #insurance #rates for some drivers.

LexisNexis Risk Solutions, and another data broker called #Verisk, claim to have real-world driving behavior from millions of cars.

#Actuaries have issued a call for more #precise #climate #risk #assessments, highlighting the concept of the “risk of ruin,” which refers to a critical juncture beyond which global society might be unable to adapt to the ramifications of climate change.

A collaboration between the Institute and Faculty of Actuaries ( #IFoA ) and the University of Exeter has resulted in a report titled
“Climate Scorpion: the sting is in the tail,” which makes a case for employing risk management strategies traditionally used in financial services to evaluate and convey the risks associated with climate change.

The report advocates for the consideration of “worst-case” scenarios regarding climate change. It also issued a warning that the pace of global warming could be #accelerating, with the likelihood it could surpass the 1.5°C target becoming increasingly plausible.
This could lead to several tipping points, including the #collapse of the #Greenland #ice #sheets, which could have long-lasting consequences.
Unexpected sensitivity to climate change is also a concern, as what is often described as a “#tail-#risk” might have a higher probability of resulting in significant temperature increases.
Methodologies are also now suggesting that a doubling of #greenhouse #gas concentrations could lead to #temperature rises of 7°C or more.
