By comparing the numbers of extreme rainfall events in the two ensembles, we can work out if the risk of a wet winter has increased, decreased or been
unaffected by human influence on climate.
Some observed weather events will have been made more likely
by human influence on climate, some less likely, and it is a legitimate and very important field of scientific enquiry to work out which are which.
Because of large natural variability, the first approach results in an outcome suggesting that it is appropriate to conclude that there is no increase in
precipitation by human influences, although the correct interpretation is that there is simply not enough evidence (not a long enough time series).
The remaining two islands, San Miguel and Santa Barbara, the most far flung of the islands offer sanctuary to seals and nesting birds as they are not as
touched by human influences.
Right around the time Marris's piece ran, Boris was organizing an Earth Day dinner for the institute exploring a cuisine suited to the Anthropocene, this Earth age
dominated by human influences (here's the menu).
Myles Allen suggests that «some observed weather events will have been made more
likely by human influence on climate, some less likely, and it is a legitimate and very important field of scientific enquiry to work out which are which.»
One study found that an already strong El Niño in 2016 was probably
enhanced by human influence, contributing to drought and famine conditions in southern Africa.
As for whether the world's recent extreme weather was made
worse by human influence, that answer likely won't be available for years — and only if a research effort similar to the one that analyzed the 2000 U.K. floods is undertaken.
In the hunt for the beginning of the much - debated «Anthropocene» — a supposed new geologic era
defined by human influence of the planet — the new research suggests a need to look back farther in time than the arrival of human - caused climate change, atomic weapons, urbanization or the industrial revolution.
By comparing the numbers of extreme rainfall events in the two ensembles, «Weather@Home» will work out if the risk of a wet winter has increased, decreased or been
unaffected by human influence on climate.
Additionally, the researchers» detailed field data make clear that the land sinking around Washington is not primarily
driven by human influence, such as groundwater withdrawals, but instead is a long - term geological process that will continue unabated for tens of thousands of years, independent from human land use or climate change.
His announcement this week that the warming can only be
explained by human influences, brings him up to date with where the science was in the mid 1990s.»
He was not allowed to say in his written testimony that modern climate change is
dominated by human influences, that we are venturing into the unknown territory with changes in climate, or that it is very likely (> 95 percent probability) that humans are largely responsible for many of the observed changes in climate.
By comparing the numbers of extreme temperature and drought events in the two ensembles, we can work out if the risk of a heatwave or drought has increased, decreased or been unaffected
by human influence on climate.
Ongoing climate change caused
by human influences will alter the nature of how rain and snow falls; areas that are prone to dry conditions will receive their precipitation in narrower windows of time.
All told, about 20 % of the distribution of domesticated species across the Amazon seemed to be driven
by human influences, while 30 % was likely due to environmental factors such as soil composition.
Our coral reefs are endangered by many different factors, both naturally and caused
by human influence.
My take on his position is that on any climate issue whatsoever — if you can not prove there is no human influence (refute the null hypothesis by showing it is less than 5 % probable or 1 % probable or whatever), then we have to conclude that it (whatever the question is that is being looked at) is caused
by human influence.
No area of the world's ocean is unaffected
by human influence, as the accumulation of carbon, fertilizer runoff, and overfishing undermine biodiversity and the natural services that it provides.
Giaever continues ticking off the most common climate myths, going from arguing that it may not even be warming, to claiming the warming is insignificant, to asserting the warming is caused by water vapor, and ultimately that the warming is indeed caused
by human influences:
