This post was written by Peter Sinclair and Greg Laden in response to a recent Wall Street Journal Op Ed piece by Matt Ridley and Benny Peiser.

In a recent Wall Street Journal commentary, “Your Complete Guide to the Climate Debate,”
Matt Ridley and Benny Peiser ask what might make world leaders concerned about the security impacts of climate change. One answer might be the US Department of Defense.

In its 2010 Quadrennial Defense review, Pentagon experts wrote:

“…climate change could have significant geopolitical impacts around the world, contributing to poverty, environmental degradation, and the further weakening of fragile governments. Climate change will contribute to food and water scarcity, will increase the spread of disease, and may spur or exacerbate mass migration.”

If that sounds familiar, it’s because it’s today’s front page news. A 2014 Defense Department document underlined the message, calling climate warming “a threat multiplier.”

Ridley and Peiser ridicule President Obama over his “careless” statement that climate change is a greater threat than terrorism. Indeed, recent research indicates that the current Syrian refugee crisis is at least partly a result of climate change enhanced drought in the region.

Ridley and Peiser claim that global temperatures have risen only slowly. This is simply untrue. The upward march of global surface temperatures varies, as expected for any natural system such as this, but continues on an upward trend. Contrarian claims of an extended pause in global warming have been debunked over recent months by at least a half dozen studies. (See: this, this, this, this, and this.)

Ridley and Peiser also suggest that surface temperatures have risen less than earlier climate modeling had projected. This is simply untrue. Global surface temperatures have risen at a pace of about 0.15 degrees C per decade since 1990, which is within the range of earlier IPCC projections.

Ridley/Peiser suggest that current record smashing weather events are due to El Nino, not climate change.

Wrong for two reasons.

First, many of the record breaking events we have experienced over recent years happened when there was no El Nino.

Second, records that are set during an El Nino period are, obviously, compared to all other prior El Nino periods as well. This year’s El Nino is exceeding earlier El Nino years in heat and tropical storm activities precisely because of a continued rise in planetary heat.

Ridley and Peiser claim that it has been warmer at times during the last 10,000 years. This statement is not supportable. While scientists know that orbitally caused warming occurred some 8000 years ago, the most current research suggests that today’s surface temperature exceed those values, or will shortly under current trends.

It is incorrect to assert that there have been no changes in extreme storms, or flooding. In the past week we have seen a new annual northern hemisphere record in major hurricanes, with 30 storms category 3 and above this year, literally blowing away the old record of 23, with the season not yet over.

Every year for the last three years, careful and conservative researchers publishing in the Bulletin of the American Meteorological Society have studied the contribution of global warming to major weather events around the world, the papers collected in an annual volume “Explaining Extreme Events … from a Climate Perspective.” Every year the number of events attributed to global warming goes up. (See these three reports.)

The US Global Change Research Program has documented the increase in extreme precipitation events across the country, and in recent weeks, the east and gulf coast of the US have been inundated by a “1000 year rain event”, as well as a new phenomenon, coastal flooding not associated with any storm, merely the regular pull of the tides, on an ocean that has risen several inches since 1950.

Miami taxpayers are currently spending 500 million dollars on pumps and other infrastructure to remedy the flooding Peiser and Ridley say does not exist.

Ridley and Peiser make the claim that tropical storms can’t be as much of a problem now as they were in the past because the number of deaths attributed to natural disasters is reduced. The irony of this statement is stunning. The reason there are fewer deaths due to weather related natural disasters is precisely because climate science and meteorology have developed methods and models to predict and warn. That very same science is telling us about the recent, ongoing, and future changes in climate due to the burning of coal, oil, and natural gas.

Ridley and Peiser seek to confuse by conflating Arctic and Antarctic sea ice, without mentioning that the small increase in Antarctic sea ice, along with the large loss of Arctic ice, is predicted from our understanding of the global warming process, and that, globally, sea ice area is clearly in a multi-decadal decline, the very reason that our giant oil companies are lobbying so intensely for access to polar regions they know are thawing.

Similarly deceptive is the claim that “Antarctica is gaining land based ice”. Here they cite a one-off outlier study, not the other dozen studies completed since 2012 by groups from NASA, the European Space Agency and others, most using more recent data than the cited piece, and all of which show overall Antarctic land ice loss. Moreover, the author of the study cited has said that
if the sea level rise does not come from Antarctica, it obviously must be undercounted elsewhere, such as Alpine glaciers, Greenland, or thermal expansion of the oceans – since observed sea level rise is unequivocal.

That sea level rise is also the most unambiguous indicator of a warming planet. The relentless and accelerating observed rise of the seas supports the half dozen recent studies showing that global warming has not halted or paused, and continues apace.

Ridley and Peiser claim that research is increasingly showing climate sensitivity to be low. This is entirely the opposite of what has been happening. The most likely range of values of climate sensitivity (the amount of increase in surface temperature that eventually occurs as a result of the doubling of CO2 in the atmosphere) was established over a century ago. Recently revealed documents show that Exxon Mobil Corporation itself studied climate science as early as the late 70’s, and its findings were in clear agreement with the National Academy of Science 1979 report, which estimated a climate sensitivity of 3°C, plus or minus 1.5° C. Tables in Exxon’s 1982 Climate Change “Primer” for executives show predictions for 2015 markedly similar to contemporary estimates by NASA, and NOAA.

Meanwhile, the solutions for climate change are at hand.

Solar and wind energy have grown faster, and costs have plummeted further, than even most fervent supporters would have predicted a few years ago. Wind and solar are now out-competing coal and nuclear everywhere, and even gas in many markets. Recent volatility in oil and gas prices make the predictable zero cost of renewables all the more attractive, as more and more major corporations are signing power purchase agreements for renewable energy, based on markets, not political correctness.

In a recent article in Scientific American, Engineers Mark Jacobsen and Mark Deluchi have shown how 139 countries can generate their total energy needs by 2050 from wind, solar, and water technologies.

Today’s average cost of large-scale solar in the U.S. is 5 cents/kWh. The installed cost of solar is down by half since 2009. The cost of wind in the U.S. is 2.5 cents per kWh, and efficiency is about the same, and sometimes below 1 cent/kWh. (See this.)

Denmark, Scotland, Spain, and Portugal are now producing more than half their electricity from renewable sources, Germany is close to a third – and the German grid is 10 times more reliable than the US grid.(See this)

In 20 US states, contractors will put solar panels on your roof for free – and in San Antonio Texas, the utility will pay you for the privilege of putting those panels on, and lowering your utility bill. (See this and this)

It’s a business model that will spread, sooner than coal barons like Matt Ridley would like you to believe.

Polling shows again and again that large majorities of Americans across all demographics favor rapid development of renewable energy, and tough regulations for greenhouse gases.

In addition, most importantly, a large majority of Americans now believe that climate change is a moral issue that obligates government officials, and private citizens, to take action.

The tactics of confusion and distortion are losing their effectiveness, as more and more Americans experience the effects of a climate altered world first hand. It’s time to stop denying the science, and begin discussing the solutions.
