Global greenhouse gas emissions have risen to unprecedented levels despite an increasing number of policies to limit them, according to Working Group III of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Climate Change 2014: Mitigation of Climate Change assesses the options and requirements for mitigating global climate change. Avoiding dangerous climate changes means lowering global emissions by 40 to 70 percent below 2010 levels by mid-century, which can be accomplished with major institutional and technological changes.
The Obama Administration has released a National Cohesive Wildland Fire Management Strategy to prepare forests and communities for fire season and the increasing effects of climate change and to help avert future wildfires. This collaborative effort between all levels of government and tribal and public partners and stakeholders, is broader and more inclusive than previous efforts and provides a framework for decision makers on how to effectively manage forests and communities to make them less vulnerable to frequent and more intense fires.
Warming due to climate change is already prolonging and intensifying naturally occurring droughts in the U.S. Southwest and will continue to do so in the future by increasing evaporation and depleting soil moisture. The research was published recently as two separate papers in Journal of Climate and Climate Dynamics and is useful for managers in understanding the drivers of future drought, and assessing drought risk in arid regions around the world.
