Steve S beats me to it, but here's a Myles Allen quote anyway: I have argued for years that the odds on a high climate sensitivity are largely irrelevant to the warming we should
expect over the coming century, and I certainly never suggested to David that my assessment of the odds on any particular level of warming by 2100 had changed.
Not exact matches
But unless such drastic action is taken in the next few years, we are headed for a very different world, one in which seas will rise by more than 5 metres
over the
coming centuries, and droughts, floods and extreme heat waves will ravage many parts of the world (see «Rising seas
expected to sink islands near US capital in 50 years «-RRB-.
Right now, our global competitors are growing their clean energy sectors in order to dominate a market that some
expect to expand by $ 2 trillion
over the next decade.16 As we describe in our report, Creating a Clean Energy
Century, 17 China is committed to investing
over $ 700 billion in clean energy
over the
coming decade, 18 in addition to building 245 new nuclear plants19 and putting a price on carbon.
Drought is
expected to occur 20 - 40 percent more often in most of Australia
over the
coming decades.6, 18 If our heat - trapping emissions continue to rise at high rates, 19 more severe droughts are projected for eastern Australia in the first half of this
century.6, 17 And droughts may occur up to 40 percent more often in southeast Australia by 2070.2 Unless we act now to curb global warming emissions, most regions of the country are
expected to suffer exceptionally low soil moisture at almost double the frequency that they do now.3 Studies suggest that climate change is helping to weaken the trade winds
over the Pacific Ocean, with the potential to change rainfall patterns in the region, including Australia.20, 21,16,22
Climate models have proven remarkably accurate when it
comes to reproducing the long - term warming we've observed
over the last half
century, and were never
expected to reproduce the exact timing of natural events.
Scientists
expect the impacts of climate change to become increasingly stark
over the
coming century, however.
With a significantly different orbital configuration
over the
coming centuries it can not be
expected that the behaviour of the NAO and AMOC would be similar to that during the Last Interglacial.
Among illustrative irreversible impacts that should be
expected if atmospheric carbon dioxide concentrations increase from current levels near 385 parts per million by volume (ppmv) to a peak of 450 — 600 ppmv
over the
coming century are irreversible dry - season rainfall reductions in several regions comparable to those of the «dust bowl» era and inexorable sea level rise.
These rates are
expected to increase
over the
coming century, imperiling the survival of 7,000 acres of freshwater tidal wetlands that protect riverfront communities and critical infrastructure from flooding and provide habitat for species on which commercial fisheries along the entire Atlantic coast depend.
