‘The consequences of a collapse would likely be far-reaching’
Human-caused warming has led to an “almost complete loss of stability” in the system that drives Atlantic Ocean currents, a new study has found — raising the worrying prospect that this critical aquatic “conveyor belt” could be close to collapse.
Scientists have long been worried about what many call “the methane bomb” — the potentially catastrophic release of methane from thawing wetlands in Siberia’s permafrost.
But now a study by three geologists says that a heat wave in 2020 has revealed a surge in methane emissions “potentially in much higher amounts” from a different source: thawing rock formations in the Arctic permafrost.
For decades, Earth’s energy system has been out of whack.
Stability in Earth's climate hinges on a delicate balance between the amount of energy the planet absorbs from the sun and the amount of energy Earth emits back into space. But that equilibrium has been thrown off in recent years — and the imbalance is growing, according to a paper published Wednesday in the journal Nature Communications.
Carbon emissions, ocean acidification, Amazon clearing all hurtling toward new records
A new study tracking the planet’s vital signs has found that many of the key indicators of the global climate crisis are getting worse and either approaching, or exceeding, key tipping points as the earth heats up.
Overall, the study found some 16 out of 31 tracked planetary vital signs, including greenhouse gas concentrations, ocean heat content and ice mass, set worrying new records.
The findings, said one expert, "show that the uncertain future is happening now."
Following years of warnings and mounting fears among scientists, "terrifying" research revealed Wednesday that climate change and deforestation have turned parts of the Amazon basin, a crucial "sink," into a source of planet-heating carbon dioxide.
Dangerous climate thresholds that will fundamentally reshape life on Earth “are closer than once thought” and will create unavoidable, dire consequences in the short term, even if humanity gets greenhouse gases under control, according to a leaked draft of an upcoming United Nations science report obtained earlier this week by Agence France-Presse.
Researchers had long forewarned of this crisis and now they’re seeing their studies and models become real life
The heatwave gripping the US west is simultaneously breaking hundreds of temperature records, exacerbating a historic drought and priming the landscape for a summer and fall of extreme wildfire.
Scientists from agency and Noaa say Earth’s ‘energy imbalance’ roughly doubled from 2005 to 2019 in ‘alarming’ way
The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an “unprecedented” increase amid the climate crisis.
