“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.

Adaptation strategies to climate change in the Arctic: a global patchwork of reactive community-scale initiatives

Tatiana V Loboda highlights the need for long-term strategic planning in adaptation policies spanning international boundaries and including all population groups

Robust relationship between yields and nitrogen inputs indicates three ways to reduce nitrogen pollution

Understanding the decline in nitrogen-use efficiency with increasing nitrogen inputs helps us understand the dilemma between increased agricultural production and nitrogen pollution, according to Benjamin Leon Bodirsky and Christoph Müller

A regional look at HANPP: human consumption is increasing, NPP is not

Steven Running reckons the regional trend in analysis of human appropriation of net primary production (HANPP) can quantify increasing vulnerability of the local populations to any shortfall in NPP as demand approaches supply, providing an early warning system

A growing commitment to future CO2 emissions

H Damon Matthews reckons we should account for the greenhouse-gas emissions committed to by exploring new fossil-fuel reserves, as well as those associated with building fossil-fuel energy plants

What are the physical links between Arctic sea-ice loss and Eurasian winter climate?

Ian Simmonds and Pallavi D Govekar examine new evidence on the connection between rapid Arctic sea-ice retreat and cold midlatitude winters

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
