The results can give us projections
of future global warming under a variety of scenarios, and also give us an estimate of the global climate sensitivity.
Therefore, it is a (by some deliberately promoted) misunderstanding to draw conclusions from such a short trend
about future global warming, let alone climate policy.
[Further Response: Our estimates of the magnitude of
future global warming do not come from ice core data, and do not depend on it in any way.
Many factors have to be taken into account when trying to predict
how future global warming will contribute to climate change.
[Further Response: Our estimates of the magnitude
of future global warming do not come from ice core data, and do not depend on it in any way.
Both groups incorporate selected evidence
about future global warming that agrees with their objectives, avoiding a balanced appraisal of the dangers.
Back in 1988, NASA's James Hansen made some of the first projections of
future global warming with a global climate model (Hansen 1988).
He's the lead author of the new paper titled «Greater
future global warming inferred from Earth's recent energy budget» — as published in the journal Nature, December 7, 2017.
Scenarios for
future global warming show tropical SST rising by a few degrees, not just tenths of a degree (see e.g. results from the Hadley Centre model and the implications for hurricanes shown in Fig. 1 above).
For over two - thirds of the locations analyzed (and for 85 % of sites outside the Gulf of Mexico), past and
future global warming more than doubles the estimated odds of «century» or worse floods occurring within the next 18 years — meaning floods so high they would historically be expected just once per century.
«Understanding whether the probability of those high - impact events has changed can help us to plan for future extreme events, and to value the costs and benefits of
avoiding future global warming.»
Model simulations of
future global warming use analogous input; of course it is not possible to observe the future, so a variety of scenarios involving possible atmospheric concentrations of carbon dioxide, etc., are employed.
Hence for example, one of Roy Spencer's five papers captured by our literature search was put in this category, because it proposes negative feedbacks will
minimise future global warming.
Now may be the ideal moment to reexamine the origins and shortcomings of the Kyoto Protocol, and to learn its lessons
before future global warming treaties repeat its mistakes.
By Paul Chesser With food and gas prices skyrocketing, several state climate commissions are ignoring the backlash against the suddenly antiquated policy of plant - enhanced petrol, as they hope to stop the
alleged future global warming catastrophe.
The firm concluded that current Brazilian law gives the Suruí and other indigenous people who save and manage existing rainforests the rights to carbon credits generated under
future global warming deals.
Exxon showed in legal filings how California cities did not disclose said risks in bond offerings to investors when they started suing the company
over future global warming damages.
A prehistoric period of high atmospheric carbon concentration most commonly used as a marking stick against which to measure current and
future global warming produced only a tenth of the current rate of CO2 release say geologists who warn the environment may not be able to cope with such rapid change.
The bottom line from the new report from the Global Warming Policy Foundation (GWPF) is that the U.N.'s Intergovernmental Panel on Climate Change (IPCC) knew, but didn't highlight, the fact that the best available scientific evidence suggests that the earth's climate is much less sensitive to atmospheric carbon dioxide input than the climate models they relied upon to
forecast future global warming portray.
Yet, model projections of
future global warming vary, because of differing estimates of population growth, economic activity, greenhouse gas emission rates, changes in atmospheric particulate concentrations and their effects, and also because of uncertainties in climate models.
Monckton, Soon et al posit that the models themselves are flawed and over-simplified, and that, in the case of the IPCC's latest projections,
overstate future global warming by as much as three times.
Dr. David Evans, a former climate modeller for the Australian government's Greenhouse Office, says he found two mathematical errors showing that the IPCC «
over-estimated future global warming by as much as 10 times.»
