Too many politicised blogs take positions on global warming, referring to scientific studies and purporting to be fair and unbiased, but clearly having an agenda. At Carbon Clear, we try to help companies make informed decisions about how to respond to climate change. But that requires sound data.
- Annual global mean temps 1990 to 1996 dropped by almost 1%.
- Annual global mean temps rose from 1989 to 1998 by about 2%.
So a reality check for these statements is needed. Are these time periods relevant? Are the data points (i.e. years chosen) representative of long-term trends? The short answer to these questions is no and no. Changes in global mean temps over short time periods are unlikely to reveal anything significant in climate change science given the temperature amplifying effects of El Nino or the countervailing cooling effects of volcanoes. So let’s let the scientists do the science and interpret the data – we have a large enough role trying to communicate clearly climate change issues. And while we ask questions, let’s try and ensure that the science is not misused or abused.
