Planetary Boundaries 2.0 – new and improved

As Science publishes the updated research, four of nine planetary boundaries have been crossed

Four of nine planetary boundaries have now been crossed as a result of human activity, says an international team of 18 researchers in the journal Science (16 January 2015). The four are: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system. They do not signal any slowdown in human-caused global warming.

Climate change will threaten the viability of grassroots sport in Australia, and elite tournaments will have to adapt to rising temperatures, extreme rainfall and shrinking snow cover, a report has warned.

The extreme heat policies of sports such as tennis, Aussie rules and cricket will have to “dramatically improve” to protect the health of competitors at all levels, the Climate Institute analysis concluded.
