Better link checker (#936)

* Copy-and-paste link checker from OV.

* Ignores

* Some link fixes.

* lots of link fixes.

* Fix #933

* Start up a server so link checks work.

* fix one outside link, and trim ignore list.

* Two more rel links

* This link comes from BL. We redirect, but that is ok, so ignore.

* Just the path should be sufficient, I hope?

 Since the late 1980s, writer and climate change activist Bill McKibben has been a leading voice on global warming. Over the course of his career, he has discussed on the issue of climate change over the airwaves of public radio and television. In 1989, [WILL interviewed him](/catalog/cpb-aacip_16-p843r0qc0z) about his first book titled *The End of Nature*, which argues for a transformational shift in how society perceives our relationship of domination with the Earth. Speaking about his latest book *Eaarth* at the [Harvard Book Store](/catalog/cpb-aacip_15-8s4jm23h6q), he said that people across the world had already begun to feel the impacts of climate change. McKibben also discussed his founding of 350.org, a grassroots effort to mobilize citizens across the world to take action on climate change. Because more than 4,000 languages are spoken across the globe, he used the number "350," universally understood as the safe upper limit of carbon dioxide parts per million in the atmosphere, for the name of the organization. Today, 350.org works in every country to effect change on both the local and global scale, and activists around the world have dedicated themselves to the effort. [Ken Ward and Andree Zaleska](/catalog/cpb-aacip_15-7940r9m78p), two activists involved in 350.org, gave a recorded public talk in 2010 about how ordinary citizens can contribute to finding solutions to global warming. Others who took personal acts of advocacy told their stories as well. In 2008, WGBH recorded a public talk given by author and environmental activist [John Francis](/catalog/cpb-aacip_15-2f7jq0sw07), who witnessed a major oil spill in San Francisco in the early 1970s and gave up motorized transportation for 22 years in protest of environmental destruction.

After discussing how the United States has historically been the primary source of emissions, he contends that with the spread of industrialization, "we need a global process...where we can work with developing countries and say 'you have a right to develop, but don't do it the way we did it, but since we got rich doing it . . . we'll help you with these alternatives.'"

He explains, "if we increase greenhouse gases leading to warming, the warming itself will induce natural emissions of greenhouse gases," which further warm the planet. He discussed the melting of Arctic sea ice as an example of a positive feedback loop. The ice reflects the sun's radiation back into space and reduces the heat added to the atmosphere. When ice melts due to greenhouse gases that have increased global temperature, then it leaves a dark colored surface behind, which absorbs the sun's radiation and leads to more warming.

 Some artists have taken to addressing the issue of climate change through their artwork, from basket-weaving to documentary filmmaking. According to mockumentary filmmaker [Randy Olsen](/catalog/cpb-aacip_15-cc0tq5rf2m), in a panel discussion recorded by WGBH in 2008, a challenge in artistic methods of communicating climate change is the difficulty in telling a compelling, engaging story that will resonate with audiences while effectively communicating the technical and scientific evidence of anthropogenic climate change. But it is a challenge accepted by artists like Olsen and [Nathalie Miebach](/catalog/cpb-aacip_15-1v5bc3t03w). On communicating climate change through sculpture and basket-weaving, Miebach, in a public lecture on WGBH Forum Network, stated that she is "trying to explore the kind of expectations that we bring with us when we try to address a question either through science or through art, and how this visualization influences the way we understand something."

This has created a much more difficult challenge "in the effort to mobilize our country to give the kind of leadership on the global scale issues that we should be giving, like climate change," he stated.

 At a public event titled "After Copenhagen: Global Climate Change Conference," held in Boston in 2010, WGBH recorded a talk given by [Kim Knowlton](/catalog/cpb-aacip_15-w37kp7v462), PhD, a senior scientist with the Health and Environment Program at the Natural Resources Defense Council (NDRC). According to Knowlton, climate change has negative effects on allergies, respiratory health, heat stroke, and mental health, and increases the spread of many disease-causing pathogens. WGBH also recorded a public talk given by [Gwynne Dyer](/catalog/cpb-aacip_15-n00zp3w741), a journalist and historian in war studies, who discussed how some areas of the world will become uninhabitable, including low-lying coastal and hotter regions, a situation that will impact national security through increased stress on global immigration pathways. When WILL hosted a call-in show with climate scientist [Katharine Hayhoe](/catalog/cpb-aacip_16-1z41r6n955) in 2003, she reported some regions including the Great Lakes, climate changes like higher temperatures at higher latitudes and more variable precipitation will have negative impacts on crop yields. Likewise, a call-in discussion with writer and journalist [Charles Wohlforth](/catalog/cpb-aacip_16-bv79s1kz48) included a discussion about how receding glaciers in Alaska will affect runoff and water resources. Writer and photographer [Jonathan Waterman](/catalog/cpb-aacip_15-3t9d50fw80) spoke about his expedition to the Arctic National Wildlife Refuge in 2006, a voyage which revealed melting permafrost, change in tundra foliage, disappearing glaciers and dying forests. In 2004, [Paul Higgins](/catalog/cpb-aacip_16-6t0gt5fq8c), Visiting Research Fellow at the University of California, Berkeley answered listeners’ call-in questions on WILL and stated that "even the more moderate climate change scenarios . . . will also change the distribution of the goods and services that biological systems produce and that will certainly have implications for what regions and populations have resources, the resources that they need." He continued, "it's important to realize that human civilization has struggled at times with relatively small changes in climate, and we're talking about much larger changes expected as a result of human activities . . . certainly larger climate changes than any human society has ever had to endure."
