As we'll see, a few studies have begun examining whether ENSO has had a long-term impact on global surface temperatures.

Because it's a cycle/oscillation, it tends to have little impact on long-term temperature changes, with the effects of La Niña cancelling out those of El Niño.

Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp. Here we will review the results of these various studies, and a few others which we have not previously examined, to see what the scientific literature and data have to say about exactly what is causing global warming.

All of these studies, using a wide range of independent methods, provide multiple lines of evidence that humans are the dominant cause of global warming over the past century, and especially over the past 50 to 65 years (Figure 1). 2007 (S07, green), Lean and Rind 2008 (LR08, purple), Huber and Knutti 2011 (HK11, light blue), and Gillett et al. This has been added to the Sk S Climate Graphics Page.

However, unlike many greenhouse gases, aerosols are washed out of the atmosphere quickly, mostly after just 1-2 years.

Thus the main volcanic impact on long-term temperature changes occur when there is an extended period of particularly high or low volcanic activity.Research on the human dimensions of climate change has expanded rapidly in Canada over the past decade.The proliferation of academic and non-academic work across disciplines presents decision-makers with a substantial challenge in understanding what is known, not known, and necessary to know about climate change.The inputs into the model included measurements of GHGs in the atmosphere, aerosols from volcanic eruptions, solar irradiance, human aerosol emissions, and atmospheric ozone changes (ozone is another greenhouse gas). applied their model to global surface temperatures from 1897 to 1997.Their best estimate matched the overall global warming during this period very well; however, it underestimated the warming from 1897 to 1947, and overestimated the warming from 1947 to 1997.This project and report seeks to address that challenge by systematically collecting and synthesizing research from the social, health, and biophysical sciences on the Inuit regions of Nunavut, Nunavik, and Nunatsiavut published between 20.With a good understanding of how climate change is impacting Inuit, we can help to determine what are enablers and which factors are barriers to climate change adaptation.Use the controls in the far right panel to increase or decrease the number of terms automatically displayed (or to completely turn that feature off).All IPCC definitions taken from Climate Change 2007: The Physical Science Basis. At Skeptical Science, we have examined several recent studies which have used a number of diverse approaches to tease out the contributions of various natural and human effects to global warming.Human aerosol emissions (primarily sulfur dioxide [SO2]) also tend to cool the planet.The main difference is that unlike volcanoes, humans are constantly pumping large quantities of aerosols in the atmosphere by burning fossil fuels and biomatter.
