The UN estimates the world’s population to be around 8.2 billion but this number is projected to hit 10 billion by the mid-2080. But it turns out researchers may have underestimated how many people are actually on Earth.
Microplastics are silently sabotaging the planet's greenery, curbing photosynthesis, and threatening food security.
Global sea level rose faster than expected in 2024, mostly because of ocean water expanding as it warms, or thermal expansion.
The continued release of greenhouse gases into Earth's atmosphere could increase the longevity of space junk in low Earth orbit, a new paper reveals.
The density of chain grocery stores has increased globally by 23.6 percent over 15 years (from 2009 to 2023). People in countries with the most chain grocery stores per person buy more unhealthy food and are more likely to be obese.
In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence.The grandchildren of women who were pregnant during the siege still bear marks of it in their genomes.
Part of the system that pumps water, heat and nutrients around the globe is at risk. Climate change could slow the Antarctic Circumpolar Current down 20% by 2050.
This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems.
Cumulative heat stress changes our epigenetics – how our cells turn on or off gene switches in response to environmental pressure. Longer periods of extreme heat accelerated ageing in older people by more than two years.
Ice loss from the world's glaciers has accelerated over the past decade, scientists said on Wednesday, warning that melting may be faster than previously expected in the coming years and drive sea levels higher.
A pod of 157 dolphins has become stranded on a remote beach in Tasmania, with dozens already dead and efforts underway to save the survivors.
Acclaimed climate scientist Professor James Hansen and colleagues recently wrote that global temperature will not fall much below +1.5°C level, instead they will be oscillating near or above that level for the next few years.
In just five years, 930 million cubic meters of crevasses opened up in the Greenland ice sheet, equivalent to adding a crack the size of the Great Pyramid of Giza to the world's second largest ice sheet every few days.
Findings indicate rising microplastic concentrations in human brains and organs, urging deeper investigation into their health effects and distribution.
Scientists have found in lab experiments that microplastics can block blood flow in mice brains, raising concerns about human health impacts.
