Climate Science Is Not Settled

Steven E. Koonin

We are very far from the knowledge needed to make good climate policy

The idea that "Climate science is settled" runs through today's popular and policy discussions. Unfortunately, that claim is misguided. It has not only distorted our public and policy debates on issues related to energy, greenhouse-gas emissions and the environment. But it also has inhibited the scientific and policy discussions that we need to have about our climate future.

My training as a computational physicist—together with a 40-year career of scientific research, advising and management in academia, government and the private sector—has afforded me an extended, up-close perspective on climate science. Detailed technical discussions during the past year with leading climate scientists have given me an even better sense of what we know, and don't know, about climate. I have come to appreciate the daunting scientific challenge of answering the questions that policy makers and the public are asking.

The crucial scientific question for policy isn't whether the climate is changing. That is a settled matter: The climate has always changed and always will. Geological and historical records show the occurrence of major climate shifts, sometimes over only a few decades. We know, for instance, that during the 20th century the Earth's global average surface temperature rose 1.4 degrees Fahrenheit.

Nor is the crucial question whether humans are influencing the climate. That is no hoax: There is little doubt in the scientific community that continually growing amounts of greenhouse gases in the atmosphere, due largely to carbon-dioxide emissions from the conventional use of fossil fuels, are influencing the climate. There is also little doubt that the carbon dioxide will persist in the atmosphere for several centuries. The impact today of human activity appears to be comparable to the intrinsic, natural variability of the climate system itself.


Obama's Phony War on Islamic State Militants

deaths in airstrikes were reported by Syrians.

Obama murders civilian men, women and children he calls militants. Terrorists. Eyewitnesses explain otherwise. He lied claiming he'll degrade and destroy IS's fighting capability. He supports it instead.

They're US proxies. Shock troops. Foot soldiers. Boots on the ground. US special forces and CIA operatives train them in Jordan and Turkey. They're taught effective ways to kill. Dirty ways. Using chemical weapons. Committing atrocities. Including beheadings and other barbarian acts.

Syrian targets struck aren't Islamic State ones. They include vital infrastructure, oil facilities, grain silos with food, empty buildings, residential homes and noncombatant men, women and children. Exact numbers killed and injured aren't clear. Various estimates differ. The toll rises daily.

On September 23, the Los Angeles Times headlined "Syrians say civilians killed in US airstrikes," explaining video evidence from Northwestern Syria...

"...shows Idlib province residents going through motions that have become all too familiar in three years of civil war between anti-government rebels and the forces of President Bashar Assad…" They're "surveying the remnants of flattened homes and picking through the debris."


The legacy of US Attorney General Eric Holder

Tom Carter

Holder’s real legacy includes providing pseudo-legal sanction for assassination of US citizens, military commissions, and incommunicado detention; shielding war criminals, corporate criminals, and Bush-era officials from prosecution; persecuting whistleblowers and journalists; targeting protesters and antiwar activists under antiterror laws; asserting unlimited executive powers; justifying government secrecy; deporting immigrants en masse; abetting the expansion of illegal domestic spying; slashing wages and benefits for workers; and infiltrating authoritarian and fascistic legal doctrines into American jurisprudence.

On Thursday, US Attorney General Eric Holder announced that he would resign from his post in the Obama administration after six years in office. His departure was greeted with a chorus of praise in the establishment media, in which he was acclaimed as a “defender of civil rights.” Announcing Holder’s resignation, Obama said, “Through it all he’s shown a deep and abiding fidelity to one of our cherished ideals as a people, and that is equal justice under the law.” At a joint press conference to announce the resignation, Obama and Holder made repeated reference to the country’s founding documents, civil rights, equal justice and so forth.
