“Mini-IPCC” report focuses on North America

US Climate Change Science Program releases report on abrupt climate change.

Sour future for the oceans?

Call for carbon-dioxide levels to be brought down to 350 ppm to prevent ocean acidification and huge economic losses.

Predicting the climate future

Forum for the Future suggests five likely scenarios for the world in 2050.

Moving times for wildlife

Climate change is already causing disruptions in species ranges but tropical species have fewer options than those at mid-latitudes.

Climate adaptation takes the stage

Physical and social scientists must work together to make and employ the predictions needed to inform policymaking for climate adaptation and mitigation.

Monitoring the melting of the Arctic

Liz Kalaugher joins a research ship in the Canadian Arctic to find out how microwave imaging can reveal where and how fast the ice is melting.

Climate talks continue in Ghana

Deforestation and sectoral approach prove key areas for discussion.

Renewable energy: price and policy are key

Sustainable energy resources are plentiful but exploiting them at large scales is more of a challenge, heard delegates at the WREN conference.

Going sour: protecting the oceans

Including ocean acidification worries in carbon regulation would probably lower emissions targets, say researchers.

Renewable energy investment takes off

In 2007 $148 bn was invested in clean energy and energy efficiency, says the latest report for the UN Environment Programme.

Can sediment plumes reveal ice-sheet melt rates?

The melting of ice sheets and glaciers contributes to sea-level rise, yet these frozen structures are often hard to study because they are so remote. Richard Hodgkins of Loughborough University, UK, details how sediment may be able to help

Heat and drought extremes likely to stress ecosystem productivity equally or more in a warmer, CO2 rich future

Considering that Earth system models generally miss a host of heat- and drought-induced mortality mechanisms that could exacerbate adverse carbon impacts, it is logical to expect that the impacts of today's heat and drought extremes are likely underestimates of what we can expect in the future with a high fossil emissions pathway, according to Christopher Williams

Identifying exposure disparities in air pollution epidemiology specific to adverse birth outcomes

Improved methods for measuring air pollution can help identify areas with disproportionately high exposure levels that lead to health inequities, according to Laura Geer

Heat and drought extremes likely to stress ecosystem productivity equally or more in a warmer, CO2 rich future

It is logical to expect that the impacts of today's heat and drought extremes are likely underestimates of what we can expect in the future with a high fossil emissions pathway, writes Christopher Williams

Identifying exposure disparities in air pollution epidemiology specific to adverse birth outcomes

Improved methods for measuring air pollution can help identify areas with disproportionately high exposure levels that lead to health inequities, according to Laura Geer

Overallocation, conflict, and water transfers

The paradox of pervasive overallocation may be that even as it heightens the need for water transfers, it also intensifies their collateral consequences, according to Dave Owen

Bias, complexity and uncertainty in ecosystem risk assessment: pharmaceuticals, a new challenge in scale and perspective

Risk assessment must expand its scale from the molecular and cellular to that of the ecosystem with real world conditions, say Lawrence K Duffy, Kriya L Dunlap and Anna R Godduhn

Water for animal products: a blind spot in water policy

Water-use efficiency in the food system as a whole remains a blind spot, according to Arjen Y Hoekstra, with national water policies focusing on "sustainable production" rather than "sustainable consumption"

Coastal subsidence and relative sea-level rise

Manmade subsidence may be the dominant contributor to relative sea-level rise in coastal environments where subsurface fluids are heavily exploited, according to S E Ingebritsen and D L Galloway

A new paradigm in oil-spill modelling for decision making?

Oil-spill models of intermediate complexity show great merit as a screening tool for decision making, according to Michel Boufadel and Xiaolong Geng
