Yes, seriously. In the most unlikely of political talk show face-offs, Bill Nye ("The Science Guy") will debate Tennessee Republican Rep. Marsha Blackburn Sunday on climate change and what's up with recent weather in Sochi, Russia and the United States (not a joke). Bill Nye (Michael Okoniewski/AP) The exchange on "Meet The Press" promises the familiar spectacle of controversy. But the meeting also puts in stark relief how much the scientific community has failed to communicate their message on global climate change. On a core issue, scientists have consistently struggled to convince the public that they (scientists) agree humans are causing global warming. Those perceptions far underestimate how much scientists actually agree. Some of the public's mistaken perception is understandable, given few people are spending their free time reading up on climatology journals. Knowledge about scientific agreement isn't the only obstacle for supporters of efforts to curb global warming.

Assess the U.S. Climate | GlobalChange.gov Scientific assessments are essential tools for linking science and decision making. They survey and synthesize science, within and between disciplines and across sectors and regions. They highlight key knowledge that can improve policy choices and identify significant gaps that can limit effective decision making. Assessments also track progress by identifying changes in the condition of the Earth, changes in human response, and advances in science over time. Assessments have been integral components of USGCRP since our inception. We have a legal mandate to conduct a National Climate Assessment (NCA) every four years, the third and most recent of which was released in May 2014. The NCA: An emerging area of focus for USGCRP is strengthening our capacity to conduct assessments on a sustained basis. More information:

Tenenbaum ESA21: Home IPCC - Working Group I material from a violent volcanic eruption is projected far above the highest cloud, these aerosols typically influence the climate for about a year or two before falling into the troposphere and being carried to the surface by precipitation. Major volcanic eruptions can thus cause a drop in mean global surface temperature of about half a degree celsius that can last for months or even years. Some man-made aerosols also significantly reflect sunlight. The energy that is not reflected back to space is absorbed by the Earth’s surface and atmosphere. This amount is approximately 240 Watts per square metre (W m–2). To balance the incoming en­ergy, the Earth itself must radiate, on average, the same amount of energy back to space. The reason the Earth’s surface is this warm is the presence of greenhouse gases, which act as a partial blanket for the longwave radiation coming from the surface. sunlight strikes the atmosphere at a lower angle.
