As the COP23 climate conference hosted by Fiji (but to the dismay of many participants, held in Bonn) is entering its second week, the "Earth League" and "Future Earth" have put together an up-to-the-minute list entitled THE 10 SCIENCE "MUST-KNOWS" ON CLIMATE CHANGE.
 
The report comes on the day that, after three years of stable global emissions, a new report states that in 2016 emissions have started to go up again. "The news that emissions are rising after the three year hiatus is a giant leap backwards for humankind.” said Dr. Amy Luers, executive director of Future Earth.
 
"This must be the starting point for re-thinking what in the past 70 years has become our culture of short-term convenience and consumption, a culture which eventually comes at the cost of the well being of present and future generations across the world", added Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research.

1. Earth has entered a new geological epoch – the Anthropocene. This means that the Earth system is changing as a result of humans' impact.
 
2. Earth is approaching tipping points due to human pressures.
 
3. Risks of extreme weather are increasing.
 
4. Rising sea levels, ocean acidification and oxygen loss are growing threats.
 
5. The costs of climate change are already being felt today and will increase in the future. Some of the world poorest nations are bearing the heaviest burden.
 
6. Human health is at risk from air pollutants that alter the climate, and the impacts of a changing climate, which are decreasing food security and increasing the risks of disease and heat stress.
 
7. Climate change is likely to exacerbate the risk of large-scale migration and civil unrest.
 
8. The world needs to act faster: deeper cuts are needed to reduce risk of global average temperature rising 2°C above pre-industrial levels. A pathway of halving global emissions every decade is consistent with this goal.
 
9. Analyses suggest that it is possible for the world to meet Paris Agreement targets if nation states cooperate and coordinate mitigation efforts. CARBON PRICING is an important policy tool that would create substantial revenues amounting to potentially several percent of GDP.
 
10. Adaptation and resilience building are necessary even if the world succeeds with aggressive international action to reduce emissions of greenhouse gases.
