Since weather forecasting cant get next week right, a 10 year trend, I'm afraid, is climate. On the short end, but still climate.
Nope. It's weather.
Once you hit 30 years you're getting into climate.Although, in regards to
climate change, talking about such short periods of time is an absolute joke.
That's the problem with AGW disciples: they don't know the difference between weather and climate, and they think 200 years is a long time when discussing climate change.
Ah no, it is you who does not know what he's talking about regarding Weather v Climate.
"Climate is defined as statistical weather information that describes the variation of weather at a given place for a specified interval. In popular usage, it represents the synthesis of weather; more formally it is the weather of a locality averaged over some period
(usually 30 years) plus statistics of weather extremes."
http://nsidc.org/arcticmet/basics/weather_vs_climate.html"Scientists keep day-to-day weather statistics for
30 years in order to draw conclusions about local and regional
climates.
It is only when a location has 30 years of weather statistics that meteorologists can generalize and comment on the climate of a particular area."
http://weather.about.com/od/climatezones/f/weatherclimate.htm"Climate is often defined as the average weather. It is usually described in terms of the mean and variability of temperature, precipitation and wind over a period ranging from months to millions of years, but the period
is typically 30 years. "
http://www.climatechange.gov.au/climate-change/understanding-climate-change/diff..."Climate refers to the average weather conditions in a place over many years (
usually at least 30 years)."
http://epa.gov/climatechange/kids/basics/concepts.html"The World Meteorological Organization (WMO) requires the calculation of averages for consecutive periods
of 30 years,"
http://www.metoffice.gov.uk/climate/uk/averages/"Climate in a narrow sense is usually defined as the "average weather," or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years.
The classical period is 30 years,
as defined by the World Meteorological Organization (WMO). "
