Biodiversity loss, fertilizer use, climate change and land use have all exceeded Earth-System limits
Biodiversity loss, fertilizer use, climate change and land use have all exceeded Earth-System limits
Human activity over the past century and a half has pushed the Earth into critical mode, say scientists. New research published in Science finds four out of nine 'planetary boundaries' have now been crossed. Biodiversity loss, fertiliser use, climate change and land use have all exceeded the point at which the risk of sliding into a "much less hospitable" world becomes high.
Passing any one of the nine critical boundaries risks disrupting the complex and delicate interactions that exist on Earth between the land, ocean, atmosphere, ice sheets and people, says the team of 18 researchers.

2014 is the hottest year registered
Global temperatures were 0.69C (1.24F) above 20th century averages, making 2014 the warmest year in records dating back to 1880, the US National Oceanic and Atmospheric Administration (NOAA) said.
Nine of the 10 warmest years since 1880 have all occurred in the 21st century, with 1998 now ranked as the fourth warmest year on record, the experts said.
The experts have attributed the hot year largely to record high global sea surface temperatures, which were 0.57C (1.03F) above the 20th century average. Land surface temperatures were the fourth highest recorded, at 1C above average.
Six months of 2014 were also record breakers, with a record-warm December finishing off a year which also saw May, June, August, September and October experience new highs.
The new figures confirm expectations announced in early December to coincide with the latest round of UN climate change talks, that 2014 was on track to be one of the hottest, if not the hottest, year on record
