RealClimate: Recent global warming trends: significant or paused or what?

RealClimate: Recent global warming trends: significant or paused or what?
Guest commentary from Drew Shindell There has been a lot of discussion of my recent paper in Nature Climate Change (Shindell, 2014). That study addressed a puzzle, namely that recent studies using the observed changes in Earth’s surface temperature suggested climate sensitivity is likely towards the lower end of the estimated range. However, studies evaluating model performance on key observed processes and paleoclimate evidence suggest that the higher end of sensitivity is more likely, partially conflicting with the studies based on the recent transient observed warming. The new study shows that climate sensitivity to historical changes in the abundance of aerosol particles in the atmosphere is larger than the sensitivity to CO2, primarily because the aerosols are largely located near industrialized areas in the Northern Hemisphere middle and high latitudes where they trigger more rapid land responses and strong snow & ice feedbacks.

Evidence The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Scientific evidence for warming of the climate system is unequivocal.

Pictures of Pennies Hi, I'm Mitch Fincher and these pages are from a talk I gave while a Civil Engineering student at Texas Tech University. The following is the basic pattern for building cantilevered structures with Pennies. Although it looks trivial, we can build amazing structures with these pillars. Intergovernmental Panel on Climate Change The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body under the auspices of the United Nations,[1][2] set up at the request of member governments.[3] It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53. Membership of the IPCC is open to all members of the WMO and UNEP.[4] The IPCC is chaired by Rajendra K. Pachauri. The IPCC does not carry out its own original research, nor does it do the work of monitoring climate or related phenomena itself. The IPCC bases its assessment on the published literature, which includes peer-reviewed and non-peer-reviewed sources.[7] Thousands of scientists and other experts contribute (on a voluntary basis, without payment from the IPCC)[8] to writing and reviewing reports, which are then reviewed by governments.

Carbon Negative Strategies Emerging as Global Warming Solution Scientists at the Stanford University Global Climate and Energy Project have proposed taking the global warming fight to a whole new level. The problem is that we’re so far behind in greenhouse gas emissions management, that it’s time to get more aggressive. Rather than simply trying to reduce the carbon we put into the atmosphere, the Stanford team proposes a carbon negative strategy in which plants are deployed on a massive scale to grab carbon out of the atmosphere.

Two degrees: Will we avoid dangerous climate change? 09 Dec 2014, 11:30Simon Evans Limiting warming to no more than two degrees has become the internationally accepted target for climate policy, as we saw in the first blog of our series of pieces looking at the two degrees limit. Scientists think the risks of climate change increase as temperatures rise.

Who We Are CGIAR is the only worldwide partnership addressing agricultural research for development, whose work contributes to the global effort to tackle poverty, hunger and major nutrition imbalances, and environmental degradation. It is carried out by 15 Centers, that are members of the CGIAR Consortium, in close collaboration with hundreds of partners, including national and regional research institutes, civil society organizations, academia, development organizations and the private sector. The 15 Research Centers generate and disseminate knowledge, technologies, and policies for agricultural development through the CGIAR Research Programs. The CGIAR Fund provides reliable and predictable multi-year funding to enable research planning over the long term, resource allocation based on agreed priorities, and the timely and predictable disbursement of funds. The multi-donor trust fund finances research carried out by the Centers through the CGIAR Research Programs.

Getting rich off global warming On the opening morning of the inaugural National Adaptation Forum, I was eating breakfast at a stand-up table in the exhibition hall when a mustachioed man of middle age plopped his cherry Danish next to my pile of conference literature, a mess of pamphlets and reports with titles like Getting Climate Smart: A Water Preparedness Guide for State Action, and Successful Adaptation: Linking Science and Policy in a Rapidly Changing World. The nametag dangling above the Danish identified the man as Michael Hughes, director of public works for the Chicago suburb of Elmhurst. Like many attendees, Hughes was part of a new national emergency-response team without being fully aware of it.
