The planet is
warming at an unprecedented rate and reducing emissions of greenhouse gasses alone is not enough to remove the risk.
The part of the paper that has generated all the publicity («
warming at an unprecedented rate», and all that) and got it accepted at Science is unsupported by the data.
Forced to
warm at an unprecedented rate through the massive burning of heat - trapping gasses by human beings, this layer is now rapidly thawing, providing an amazing source of heat and fuel for wildfire ignition.
They say that the Arctic is
warming at an unprecedented rate, but the cold now being experienced by the Northern US is from freezing Arctic winds.
Not exact matches
Coral reefs, which support diverse communities of fish and other marine life, are declining globally
at unprecedented rates due to human - caused impacts, such as
warming waters and ocean acidification.
However, the big unknown remaining is whether corals can adapt to global
warming, which is now occurring
at an
unprecedented rate —
at about two orders of magnitude faster than occurred with the ending of the last Ice Age.
However, while most «skeptics» agree we are in a
warming trend, for most, the main challenges are (i) that it is not shown to be
at unprecedented levels or
rates (for the last millenium or so) and (ii) that it is not shown to be principally manmade.
Now, two new studies conducted by researchers
at NASA and the University of California, Irvine, have revealed that glaciers in West Antarctica are retreating
at an
unprecedented rate due to
warm water circulating beneath the ice shelf.

I've found myself
at the center of such episodes more than once, as a result of what's become known as the iconic «hockey stick» diagram that my co-authors and I had published in the late 1990s — a graphic display of the data that made plain the
unprecedented rate of global
warming.
At a stroke, put the end to the claim that the
rate of
warming was «
unprecedented» (thus un-natural cause — man made)
Indeed, an Australian reporter even suggested that «years of global
warming and increased CO2 emissions have caused these trees to grow
at an
unprecedented rate, providing more fuel for these fires.»
Consequently, the next time a serious drought takes hold of some part of the world and the likes of Al Gore blame it on the «carbon footprints» of you and your family, ask them why just the opposite of what their hypothesis suggests actually occurred over the course of the 20th century, i.e., why, when the earth
warmed - and
at a
rate and to a degree that they claim was
unprecedented overthousands of years - the
rate - of - occurrence of severe regional droughts actually declined.»
«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will
warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The
rate of rise of temperature in the 20th and 21st centuries is
unprecedented compared to the
rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels
at projected
rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's
rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach
at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
Jim D — Nice of you to admit it's not
warming at the
unprecedented, catastrophic
rate that the media would have us believe for the last 20 years.
COMMON MISCONCEPTIONS ABOUT GLOBAL
WARMING MYTH 1: Global temperatures are rising
at a rapid,
unprecedented rate.
Global
Warming alarmists tell us that the world is heating
at an
unprecedented rate due to the
unprecedented output of human greenhouse gas emissions.
With virtually all CAGW projections diverging further from reality, CAGW's survival depends on propagandizing lies and half - truths: the «97 %» meme, severe weather, sea levels, global
warming trends, ocean acidification, polar bear and penguin populations, polar ice caps, etc., are all supposedly worsening
at «
unprecedented»
rates.
«Because greenhouse gas concentrations are increasing
at rates unprecedented for the past 800,000 years, human - caused
warming will be superimposed on the «natural» trend,» he said.
If you read this blog regularly, you probably noticed we include quite a bit of information about how both the Arctic and Antarctica are
warming and sea ice and glaciers are melting
at unprecedented rates.
You're no doubt aware by now that the Arctic is melting
at unprecedented rates and by and large the world's glaciers are retreating, both with the blame placed on
warming temperatures.
Thus, sea ice has melted
at an
unprecedented rate and is now caught in a vicious cycle known as the ice - albedo feedback: as sea ice retreats, sunshine that would have been reflected into space by the bright white ice is instead absorbed by the ocean, causing waters to
warm and melt even more ice.
The current
warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding
at a
rate that is
unprecedented over decades to millennia.1 Earth - orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale.
