Carbon dioxide levels rose by more than two parts per million (ppm) for the 11th consecutive year: the highest sustained rate of CO₂ increases since monitoring began 65 years ago.…Continue readingGreenhouse gas emissions rose at ‘alarming’ rate last year, US data shows
Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for…Continue readingCarbon dioxide peak for 2022 more than 50% higher than pre-industrial levels
Four key climate change indicators—greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification—set new records in 2021. “It is just a matter of time before we see…Continue readingFour climate change records broken in 2021: WMO State of the Climate Report
A new record for the highest daily level of carbon dioxide in the atmosphere has been set this week, ringing alarm bells about the pace of global warming. The…Continue readingRecord carbon dioxide levels alarm scientists
Amazon rainforest becomes a savanna The 2.5 million square mile rainforest is so vast it creates its own rainfall and is home to 10% of the world’s species. But…Continue readingThe world is ‘perilously close’ to irreversible climate change
For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor…Continue readingIncrease in atmospheric methane set another record during 2021. Carbon dioxide levels also record a big jump
Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion tons, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and…Continue readingGlobal carbon dioxide emissions rebounded to their highest level in history in 2021
After small drop in 2020, global electricity demand grew by 6% in 2021. It was the largest ever annual increase in absolute terms (over 1,500 TWh). Around half took place…Continue readingIEA: Electricity CO₂ emissions reach record high and set to remain constant to 2024
In addition to drastically cutting global fossil fuel emissions, society needs to develop and use technologies to remove the CO2 already in the atmosphere. Geologist Peter B. Kelemen is…Continue readingCarbon dioxide removal technologies take a giant step forward
The warming of the planet is taking a deadly toll on seabirds that are suffering population declines from starvation, inability to reproduce, heat waves and extreme weather. One estimate…Continue readingHuman greenhouse gas emissions kill seabirds
Climate change and warming waters are pushing black-browed albatross break-up rates higher. Typically after choosing a partner, only 1-3% would separate in search of greener romantic pastures. But in…Continue readingHuman emissions causing increasing rates of albatross break-ups
The World Meteorological Organization reported Monday that greenhouse gas concentrations hit a new record high last year and increased at a faster rate than the annual average for the…Continue readingUN: Greenhouse gas concentrations hit a new record in 2020
Maps of fossil-fueled power plants’ CO2 emissions. Taller spikes indicate that plants emit CO2 at higher levels. Colors signify plants’ primary fuels (blue = coal, yellow = natural gas,…Continue readingReducing CO₂ emissions by targeting the world’s hyper-polluting power plants
The wildfires in the American West are burning vast expanses of specially protected forests — those that are part of carbon-offset projects meant to counterbalance the carbon dioxide pollution…Continue readingWildfires are ravaging forests set aside to soak up greenhouse gases
Global greenhouse gas emissions must peak in the next four years, coal and gas-fired power plants must close in the next decade and lifestyle and behavioural changes will be…Continue readingGreenhouse gas emissions must peak within 4 years, says leaked UN report
This backing for coal, oil and gas is “reckless” in the face of the escalating climate emergency, according to the report’s authors, and urgent action is needed to phase out…Continue reading‘Reckless’: G20 states subsidised fossil fuels by $3tn since 2015, says report
“Carbon dioxide going up in a few decades like that is extremely unusual”. “For example, when the Earth climbed out of the last ice age, carbon dioxide increased by…Continue readingCarbon dioxide levels hit 50% higher than preindustrial time
