A new study finds that while many Americans misjudge the relative climate impact of dozens of behaviors, they readily commit to higher-impact choices when they get more information. Willingness to engage in actions promoting larger-scale change falls off, however, if interventions focus solely on individual behavior.
A new study led by UBC researchers suggests that the summer solstice—the longest day of the year—may serve as a key cue for plant growth and reproduction. But in a changing climate, relying on this fixed signal may no longer help plants to survive or thrive.
Opening any new North Sea oil and gas fields is incompatible with achieving the Paris Climate Agreement goals of limiting warming to 1.5°C or holding warming to “well below 2°C” relative to preindustrial levels, finds a new report published by UCL academics.
Researchers studied an ancient forest of bald cypress trees preserved in subfossil form at the mouth of Georgia’s Altamaha River. Using radiocarbon dating and tree-ring analysis, they revealed a dramatic shift in growth patterns: around 500 A.D., these trees began growing faster – but living far shorter lives. Their average lifespan plunged from more than 470 years to just 186, coinciding with the Vandal Minimum, a sixth century climate crisis marked by global cooling and upheaval, likely caused by volcanic eruptions and possibly even a comet impact.
