Given the complexity of climate change, researchers produced a remarkably slim summary last month. At just 23 pages, no policymaker can be excused from not knowing the facts ahead of the crucial meeting in Bali, Indonesia, this month. This is the key document on the current assessment of climate change. It is the tightly distilled, peer-reviewed work of several thousand researchers and endorsed...

The Stern Review (2006) has come to symbolize something of a dividing line in the evolution of the common appreciation of the climate problem. It is fair to say that during the last decade, there has been a gradual but uneven increase in the perceived gravity of anthropogenic climate change, among scientists and, with some time lag, the general public. However, save the United Nations’ Intergov...

Climate change has led to significant changes in weather elements recent years, which, affect the various aspects of human life, including water supply, food security, and so on. In this research, effects climate on Kor basin Fars province under different scenarios for four parameters minimum maximum temperature, mean temperature precipitation using Beijing Center System Model (BCC-CSM 1.1), Ce...

The delivery of effective climate adaptation on the ground requires that (climate adaptation) practitioner community be better incorporated into process producing, gathering and synthesizing evidence as part Intergovernmental Panel Climate Change (IPCC) process. This is not a recent issue co-production knowledge, goes beyond traditional realms ‘science speaks to power’, can only fully inform ad...

To increase public trust in the results of climate science, we recommend that the uncertainties inherent in climate forecasts be made explicit. In cases where these uncertainties can be legitimately expressed as probabilities, we suggest that use of a dual verbal/numerical format for expressing uncertainty (e.g., ‘likely (65-80%)’) will enhance communicative effectiveness. We also propose use o...

The climate-security century is here. Both the United Nations Intergovernmental Panel on Climate Change (“IPCC”) and U.S. Fourth National Assessment (“NCA”) recently sounded alarm climate change’s “super-wicked” destabilizing security impacts. Scientists professionals alike reaffirm what we are witnessing with our own eyes: earth warming at a rapid rate; change affects international peace in co...

There is growing scientific evidence that, as a result of increasing anthropogenic carbon dioxide (CO2) emissions, absorption of CO2 by the oceans has already noticeably increased the average oceanic acidity from pre-industrial levels. This global threat requires a global response. According to the Intergovernmental Panel on Climate Change (IPCC), continuing CO2 emissions in line with current t...
