Data gathered in Lewes and around the country shows dramatic improvements over the long term, taking into
account natural variability in the climate from year to year.
Not exact matches
I've noted here before that
climate campaigners who seek to use real - time events to engage the public can only retain credibility if they
account for
natural variability in framing their case and explain that the odds of such events are shifting.
In so far as M&M are trying to distort the
climate data over the last 1000 years to show that the so - called «Medieval Warm Period» replicates or exceeds the current warming — and so
natural variability could possibly
account for that warming — I thought it worthwhile to put out some information about Medieval
climate.
Contrary to another claim made by Betts, we are conversant with that research and have recently contributed to it by showing that
climate models do accommodate recent temperature trends when the phasing of
natural internal
variability is taken into
account — as it must be
in comparing a projection to a single outcome.
Firstly, even with man - made global warming taken into
account, because of the short - term noise due to the internal
variability in the
climate system,
climate models predict that there will be decades where
natural cycles dampen the man - made warming trend.
(3)
Natural as well as human - induced changes should be taken into
account in climate model simulations of atmospheric temperature
variability on the decade - to - decade time scale.
However, changes
in climate at the global scale observed over the past 50 years are far larger than can be
accounted for by
natural variability.
The petition reads
in part: «Studies of a variety of
natural processes, including ocean cycles and solar
variability, indicate that they can
account for variations
in the Earth's
climate on the time scale of decades and centuries.
Regional climatic changes played a role as well, which was particularly relevant
in Amazon rainforests, which
accounted for 42 % of the global NPP increase, owing mainly to decreased cloud cover and the resulting increase
in solar radiation (note that it is basically impossible to determine how much of this increase
in NPP is a result of recent global
climate change vs.
natural climate variability, although both are likely to have played a role).
