Slate: More Science Won't Solve Climate Change Gridlock
When people hold strongly conflicting values, interests, and beliefs, there is not much that science can do to compel action. Indeed, more research and more facts often make a conflict worse by providing support to competing sides in the debate, and by distracting decision-makers and the public from the underlying, political disagreement. In such cases each side will claim to have the scientific high ground.
Writing in the New York Times last week, Al Gore made exactly this point about climate change by noting that "the science has become clearer and clearer." Yes, there is a robust scientific consensus that human activity is causing the atmosphere to warm up. But so what? Decision-makers need to know how climate change will affect specific political jurisdictions, and, more importantly, what types of interventions will make a difference, over what time scales, at what costs, and to whose benefit--and whose detriment.
Sarewitz's op-ed resonates with my own views on the issue shared earlier this week at Dot Earth and in a news report at the NYTimes.com. Until we propose policies that reflect the values and input of a range of political voices and until we communicate about the national and local benefits of those policies, we may never overcome political paralysis. Moreover, the more that scientists and environmental advocates become distracted by the climate skeptic movement, responding to every new attack with a combo of war rhetoric and technical defenses of the science, the deeper the divide on climate change is likely to grow.
Sarewitz's full article is a must-read, but here's how he ends:
Politics isn't about maximizing rationality, it's about finding compromises that enough people can live with to allow society to take steps in the right direction. Contrary to all our modern instincts, then, political progress on climate change requires not more scientific input into politics, but less. Value disputes that are hidden behind the scientific claims and counterclaims need to be flushed out and brought into the sunlight of democratic deliberation. Until that happens, the political system will remain in gridlock, and everyone will be convinced that they are on the side of truth.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
It's a "canary in the coalmine," said one climate scientist.
- A team of researchers discovered that permafrost in Northern Canada is melting at unusually fast rates.
- This could causes dangerous and costly erosion, and it's likely speeding up climate change because thawing permafrost releases heat-trapping gasses into the atmosphere.
- This week, Canada's House of Commons declared a national climate emergency.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
