Our precious thin atmosphere

Click on this link to see a beautiful photo of the Earth by the Goddard Space Flight Center. What is stunning to me is the thin-ness of the Earth's precious atmosphere. Click on the image for a much-enlarged version. earth-blue-marble How was this photo taken?

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across. Much of the information contained in this image came from a single remote-sensing device-NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor’s view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data.

Climate: OJ and the Haystack

Why Climate Change Denial Is Like the O.J. Trial is an interesting article. The essence is that the climate denialists are using the same techniques as the OJ defense team: Find anything resembling a needle in a vast haystack of data, then claim that the presence of the needle casts doubt on the character of the haystack itself. Because there is an overwhelming pile of evidence in support of anthropogenic global warming, there are bound to be occasional pieces of data that can appear to contradict the mass of affirmative information. The pile is overwhelming, especially to non-scientists. Therefore few have the patience to understand the whole thing. Those who want to spin the counter argument claim that, because the two sides are both represented, therefore the issue is in doubt. And, as in the OJ trial, if there is cause for doubt, then no action is to be taken.

And now it’s Kirk Cameron’s turn . . .

Jenny McCarthy, a famous non-scientist who has toured the country warning that vaccines caused her son's autism, now says that her son doesn't actually have autism and that vaccines might not actually cause autism. You see, real science doesn't make things up. Real science is a self-critical activity . . . Now it's time for Kirk Cameron to see the light.

Payday loan opponents struggle to get a fair hearing

Payday loans are high-interest short-term unsecured small loans that borrowers promise to repay out of their next paycheck, typically two weeks later. Interest rates are typically 300% to 500% per annum, many multiples higher than the exorbitant rates charged by banks on their credit cards. A typical payday borrower takes out payday loans to pay utility bills, to buy a child’s birthday present or to pay for a car repair. Even though payday loans are dangerous financial products, they are nonetheless tempting to people who are financially stressed. The growth of payday lenders in the last decade has been mind-boggling. In many states there are more payday lenders than there are McDonald’s restaurants. In Missouri Payday lenders are even allowed to set up shops in nursing homes. Missouri’s payday lenders are ferociously fighting a proposed new law that would put some sanity into a system that is often financially ruinous for the poor and working poor. Payday lenders claim that the caps of the proposed new law would put them out of business. Their argument is laughable and their legislative strategy is reprehensible. Exhibit A is the strategy I witnessed Thursday night, February 18, 2010. On that night, Missouri State Senator Joe Keaveny and State Representative Mary Still jointly held a public hearing at the Carpenter Branch Library in the City of St. Louis City to discuss two identical bills (SB 811 and HB 1508) that would temper the excesses of the payday loan industry in Missouri. Instead of respecting free and open debate and discussion regarding these bills, payday lenders worked hard to shut down meaningful debate by intentionally packing the legislative hearing room with their employees, thereby guaranteeing that A) the presenters and media saw an audience that seemed to favor payday lenders and B) many concerned citizens were excluded from the meeting. As discussed further down in this post, payday lenders are also responsible for flooding the State Capitol with lobbyists and corrupting amounts of money.carpenter-branch-library When I arrived at 7:00 pm, the scheduled starting time, I was refused entry to the meeting room. Instead, I was directed to join about 15 other concerned citizens who had been barred from the meeting room. There simply wasn’t room for us. But then who were those 100 people who had been allowed to attend the meeting? I eventually learned that almost all of them were employees of payday lenders; their employers had arranged for them to pack the room by arriving en masse at 6 pm. Many of the people excluded from the meeting were eventually allowed to trickle into the meeting, but only aspayday-employees other people trickled out. I was finally allowed into the meeting at 8 pm, which allowed me to catch the final 30 minutes. In the photo below, almost all of the people plopped into the chairs were payday lender employees (the people standing in the back were concerned citizens). This shameful tactic of filling up the meeting room with biased employees has certainly been used before.
