CRU Information Sheet no. 5: The Millennial Temperature Record
Natural forcing from the sun and volcanoes dominate the pre-1850 part of the record and only human activities appear to adequately explain the rise in temperature during the 20th century (Crowley, 2000). ...

CRU Information Sheet no. 13: Volcanoes and their effect on climate
Other natural (e.g. solar output changes) and anthropogenic (increases in greenhouse gases and sulphate aerosols) operate on decadal-to-century timescales and any changes over short timescales are very difficult to distinguish from the natural variability of the climate system. Volcanic-induced ...

Climate change - Human Influence
Sulphate aerosols, though not greenhouse gases, are nonetheless very important to global climate. Sulphate ... of greenhouse gases, like carbon dioxide and methane have had a net warming effect, emissions of sulphate have had a net cooling effect. The overall effect is one of net global warming, but ...

Science and the Environment Bulletin: Decoding Canada's Environmental Past
America in the year following a major volcanic eruptionproof that major events, even in other parts of the world, can have a profound impact on geographically distant environments. Because the sulphate aerosols emitted by volcanoes are similar to, but at much higher concentrations than, those released by many manmade sources today, increasing levels of pollution may have a similar cooling effect ...
