What Would It Take For The Paris Climate Summit To Succeed?

Published by Forbes

There’s a lot of focus now on the politics of Paris. Will poor countries get the "climate aid" they want? Will China agree to reduce its growth, leaving millions more in poverty, by committing to far-reaching carbon cuts? What will be the wording of the treaty that emerges? It’s easy to become cynical. Let’s instead take a step back and ask a much more interesting question: what would it take for Paris to succeed? By this, I don’t mean that the delegates manage to sign some kind of treaty. I mean, what would it take for Paris to have a real impact on climate...

Is Climate Change Our Biggest Problem?

Published by PragerU

Is man-made climate change our biggest problem? Are the wildfires, droughts and hurricanes we see on the news an omen of even worse things to come? The United Nations and many political leaders think so and want to spend trillions of tax dollars to reverse the warming trend. Are they right? Will the enormous cost justify the gain? Economist Bjorn Lomborg, director of the Copenhagen Consensus Center, explains the key issues and reaches some sobering conclusions.

The Paris Climate Summit Will Fail, For A Pretty Simple Reason

Published by Forbes

If you don’t learn from history, you’re bound to repeat it. Here in Saint-Denis, northern Paris, a history lesson is sorely needed. Thousands are gathering here for the 21st international global warming meeting. Hotels are already near-full, broadcasters are setting up, protestors are preparing to roar. All because this summit is "the last chance" to avert dangerous temperature rises, if we listen to the Earth League or a bunch of others. It’s going to be "too late" if a meaningful treaty isn’t negotiated here in the next few days, says the French...

Blowing hot air: Governmental carbon-cutting promises are inadequate

Published by Hindustan Times

Paris will soon host the 21st global climate conference (November 30-December 11) — and environmentalists have high hopes that this time, negotiators will agree on a carbon-cutting treaty. In 20 years there have been a few highs such as a treaty negotiated in Kyoto in 1997 and many lows like the political chaos and disappointment of Copenhagen in 2009. There has been one constant: despite all the talk, there has been no real impact on temperature rises. The Kyoto Protocol fell apart, and the only significant global carbon cuts have come from economic downturns, not international pacts...

Make it cheaper to go green

Published by Boston Globe

With leaders gathering in Paris later this month for a major climate summit, it is clear that our modern-day approach to climate change is backwards. We spend a massive amount of effort trying to make carbon too expensive and unappealing for the world to use. Instead, we need to make green energy much cheaper. Our dependency on carbon-emitting fuels is overwhelming. The fact is that the world will not stop using fossil fuels for many decades. Despite all the excitement about green energy, globally we get a minuscule 0.4 percent of our energy from wind and solar panels.

Pre-Judging Paris

Published by Project Syndicate

The United Nations Climate Change Conference in Paris later this month is being billed as an opportunity to save the planet. It is no such thing. As I show in a new peer-reviewed paper, even if successful, the agreement reached in Paris would cut temperatures in 2100 by just 0.05° Celsius. The rise in sea level would be reduced by only 1.3 centimeters. This may seem surprising: we constantly hear how every country has made important commitments to reduce CO2 emissions – the so-called “Intended Nationally Determined Contributions,” or INDCs. According to the UN’s...

Gambling the World Economy on Climate

Published by Wall Street Journal

The United Nations climate conference in Paris starting Nov. 30 will get under way when most minds in the French capital will still understandably be on the recent terror attacks. But for many of the 40,000 attendees, the goal is to ensure that climate change stays on the global economic agenda for the next 15 years. The Paris conference is the culmination of many such gatherings and is expected to produce agreements on combating climate change. President Obama and the dozens of other world leaders planning to be in Paris should think carefully about the economic impact—in particular...

Romm Critique of COP21 Impact Deeply Flawed

Published by Huffington Post

My peer-reviewed research paper sparked an emotional response from environmentalist Joe Romm. His complaint is that I am overly pessimistic about Paris. In his customary style of ad hominem attacks and fervid language, he calls me a "widely debunked confusionist", labels my research "nonsense", a "lie" and "intellectually indefensible", and suggests his supporters use social media to go after the journal that published it. Setting aside Mr. Romm's insults and attempts at provocation, I'd like to respond to the actual assertions...

Impact of Current Climate Proposals

Published by Global Policy

This article investigates the temperature reduction impact of major climate policy proposals implemented by 2030, using the standard MAGICC climate model. Even optimistically assuming that promised emission cuts are maintained throughout the century, the impacts are generally small. The impact of the US Clean Power Plan (USCPP) is a reduction in temperature rise by 0.013°C by 2100. The full US promise for the COP21 climate conference in Paris, its so-called Intended Nationally Determined Contribution (INDC) will reduce temperature rise by 0.031°C. The EU 20-20 policy has an impact of...

This Child Doesn’t Need a Solar Panel

Published by Wall Street Journal

In the run-up to the 2015 U.N. Climate Change Conference in Paris from Nov. 30 to Dec. 11, rich countries and development organizations are scrambling to join the fashionable ranks of “climate aid” donors. This effectively means telling the world’s worst-off people, suffering from tuberculosis, malaria or malnutrition, that what they really need isn’t medicine, mosquito nets or micronutrients, but a solar panel. It is terrible news...
