Tomorrow, the House Foreign Affairs Committee will hold a hearing on the national security threats from melting Arctic ice. Greenwire (subscription required), the Online environmental news service, explains the rationale for the hearing:
In a report last year, the European Commission warned that the North Atlantic Treaty Organization must be prepared for an intensified “scramble for resources” as melting glaciers and sea ice open up previously inaccessible areas to exploitation. The report explicitly expressed concerns over “long term relations with Russia,” (ClimateWire, April 2, 2008).
Now, opening up ”previously inaccessible” areas to oil and gas development could also be a font of economic and national security benefits. One thing we know for sure about Arctic mineral resources–they aren’t owned by Saudi Arabia, Iran, or Venezuela, and never will be controlled by OPEC.
Yes, there will be competition for those resources, but since when is competition an automatic negative for the USA?
Clearly, there are opportunities here as well as risks–opportunities to create thousands of high-paying U.S. jobs, boost GDP by tens to hundreds of billions of dollars, and generate billions in deficit-reducing tax revenues and royalties.
More pertinently, exploitation of previously inaccessible resources could significantly diversify U.S. oil and gas–a longstanding objective of U.S. energy security policy.
But Gorethodoxy demands blind obedience by its votaries. Discussing the potential benefits of global warming is strictly verboten.

Why Is the Chicago Tribune in Bed with T Boone Pickens?
by William Yeatman
March 03, 2009 @ 11:43 am
Why Is the Chicago Tribune in Bed with T Boone Pickens? Why is the Chicago Tribune again allowing its editorial page to shill for T Boone Pickens? For the second time in 5 months, the Tribune has published a self-serving opinion piece by Mr. Pickens (Our Energy Future, 16 November 2008; Solving Our Nation’s Energy Predicament, 24 February 2009). Remove the rhetoric, and T Boone’s plan is quite simple. He wants the government to (1) force taxpayers to subsidize his wind power; (2) force taxpayers to pay for the transmission lines to deliver his wind power; (3) force consumers to buy his wind power; (4) force consumers to buy T Boone’s natural gas “saved” by using his wind power to power their cars. America gets expensive energy and T Boone Pickens gets rich. As CEI’s Marlo Lewis artfully put it: “This T Boone-doggle Pickens your pocket.”

Why Alarmism?
by William Yeatman
March 03, 2009 @ 5:31 pm
When it comes to global warming, dire predictions seem to be all we see or hear. But is the alarmism justified?
In today’s Cato Daily Podcast, climatologists Patrick Michaels explains why the news and information we receive about global warming have become so apocalyptic. According to Michaels, a Cato senior fellow in environmental studies, science itself has become increasingly biased, with warnings of extreme consequences from global warming becoming the norm. That bias is then communicated through the media, who focus on only extreme predictions.

There are only 2 weeks left to sign up for the Heartland Institute’s second International Conference on Climate Change in New York City, March 8-10, 2009! Are you sick and tired of climate alarmism based on flawed science and economics? Then join hundreds of the world’s elite scientists, economists, legal experts, business people, legislators, and members of the media in New York City to discuss the latest science, economics, and politics of global warming.
When it comes to global warming, dire predictions seem to be all we see or hear. In Climate of Extremes, a new book by climatologists Patrick Michaels and Robert Balling Jr., we learn why the news and information we receive about global warming have become so apocalyptic. The science itself has become increasingly biased, with warnings of extreme consequences from global warming becoming the norm. That bias is then communicated through the media, who focus on only extreme predictions.

Why Is HuffPo Pimping Ethanol?
by William Yeatman
February 18, 2009 @ 2:48 pm
Yesterday’s edition of the Internet news juggernaut, The Huffington Post, ran an ethanol love song written by Bob Dinneen, who is identified in his HuffPo biography as “the ethanol industry’s lead lobbyist before the Congress and Administration.” Given that Mr. Dinneen is a professional shill, there’s no need to repeat his self-serving argument. Whatever is his case for ethanol, the bottom line is his bottom line. But it is worth saying a few things about the reality of ethanol. Ethanol is touted as a solution to America’s dependence on foreign oil. It is true that ethanol—an alcohol distilled from corn—can be used to run cars. “Can,” however, does not mean “should.” Indeed, ethanol is a bad idea both economically and environmentally. For starters, ethanol is twice as expensive as gasoline, so filling your car with ethanol raises your fuel bill. Also, by turning corn, which is usually used food, into fuel, demand for food increases. So, increased ethanol use raises your food bill too. Finally, ethanol is awful for the environment—it results in increased corn cultivation, which leads to greater nitrogen runoff, which causes massive, oxygen-depleted “dead zones” in our streams, lakes, rivers and oceans. Yet Americans are forced to buy ethanol thanks to laws written by the ultra-powerful corn and agribusiness lobbies. Ethanol makes corn growers and ethanol producers rich, so they have spent millions lobbying legislators to pass (1) generous taxpayer subsidies for ethanol production, and (2) a Soviet-style production quota that forces Americans to use a certain percentage of ethanol in the nation’s fuel supply (last year, Americans were forced to buy 9 billion gallons of corn fuel). So why is the Huffington Post pimping the ethanol boondoggle when so many others have stopped supporting these corrupt programs? King corn and its agribusiness allies could never convince Americans to buy ethanol; instead, they convinced Congress to force ethanol on consumers. The industry’s existence is a powerful testament to lobbyists’ ability to rig the rules of the game to enrich their clients at the expense of everyday Americans—a tacit endorsement from the Huffington Post can only help the ethanol lobby continue to do so. Huff Po is generally a well-done publication, so why run a pitch by a guy who is trying to get rich by screwing the consumer? Since when are greedy lobbyists palatable to the left?

EU Pitches Climate Plan
by William Yeatman, Cooler Heads Digest
February 02, 2009 @ 11:15 am
From http://www.globalwarming.org/
The European Union Commission this week outlined a diplomatic framework for negotiations to craft an international climate change treaty. The document cites an independent calculation that it could cost 175 billion Euros a year by 2020 to fight climate change. Yet the Commission dodges the key question of who will pay for this “green” revolution in energy production, stating only that, “international financial support for actions exceeding a country’s domestic capabilities should come from sources including public funds and international carbon crediting mechanisms.”
So the question remains: Who’s going to pay what? The United States Senate remains unlikely to ratify any international agreement to ration energy that doesn’t also include rapidly developing countries responsible for an ever-greater share of global emissions. Developing countries, however, refuse to put global warming over poverty reduction and their “right to develop.” The EU procrastinates. Global emissions continue to rise (while temperatures stay the same).

California Blocks People of Santa Barbara on Drilling
by William Yeatman, Cooler Heads Digest

From http://www.globalwarming.org/
The Los Angeles Times today reports that the California State Lands Commission overturned a proposal by county officials and environmentalists for expanded oil production off the Santa Barbara coast. Environmentalists helped craft the measure, which allowed a Texas energy company to drill new wells in exchange for the eventual retirement of four platforms. Despite broad, bi-partisan support for the agreement in Santa Barbara, the State Lands Commission objected to the deal because its approval would have sent “a message heard very, very clearly by those who call for ‘drill, baby, drill,’” said Lt. Governor John Garamendi (D), who sits on the Commission, and who intends to run for Governor.

Climate Policy Lessons from Europe

From http://www.globalwarming.org/
The recent European Union climate agreement provides a useful warning to incoming President Obama and his team when they consider what to do about global warming. The rhetoric from the EU may sound nice, but when it comes to translating words into action, Europe has shown that the job is harder than it looks. EU member states have found it very difficult to reduce emissions, meet renewable energy targets or create lasting green jobs.

Dampak akibat penipisan ozon
Lubang ozon di Antartika disebabkan oleh penipisan lapisan ozon antara ketinggian tertentu seluruh Antartika pada musim semi. Pembentukan 'lubang' tersebut terjadi setiap bulan September dan pulih ke keadaan normal pada lewat musin semi atau awal musim panas.
Dalam bulan Oktober 1987, 1989, 1990 dan 1991, lubang ozon yang luas telah dilacak di seluruh Antartika dengan kenaikan 60% pengurangan ozon berbanding dengan permukaan lubang pra-ozon. Pada bulan Oktober 1991, permukaan terendah atmosfer ozon yang pernah dicatat telah terjadi di seluruh Antartika.
Kemerosotan ozon global
Pengukuran latar dan satelit menunjukkan pengurangan signifikan terhadap jumlah kolom ozon pada musim dingin dan panas bagi kedua hemisfer utara dan selatan pada garis lintang tengah dan tinggi. Didapati aliran ke bawah ini pada tahun 1980 agak besar bila dibandingkan dengan tahun 1970. Tiada statistik aliran signifikan dapat ditentukan bagi kawasan tropika semasa tahun 1980. Dengan kemajuan komputer model bagi pemusnahan stratosfer ozon dapat menjelaskan pemerhatian aliran jumlah ozon di ketinggian pertengahan pada musim panas, tetapi hanya sebagian darinya pada musin sejuk. Ini bermakna pada masa depan perubahan global ozon belum bisa diramalkan lagi.
Satelit
Penggunaan satelit mengelilingi kutub seperti Satelit NASA Nimbus7 yang membawa peralatan "Total Ozone Mapping Spectrometer" (TOMS) telah merevolusikan pemantauan ozon sejak 20 tahun yang lalu. Kedudukan yang baik di atas cakrawala dan kemampuan setiap satelit untuk perjalanan mendatar seluruh dunia, menyediakan liputan yang lebih baik dari stasiun darat. Ini sangat tinggi nilainya untuk menentukan aliran global. Ketepatan sensor satelit menggunakan prinsip yang sama dengan spektrofotometer Dobson.
Spektrofotometer Dobson
Spektrofotometer pertama diciptakan pada tahun 1920 oleh Gordon Dobson untuk mengukur jumlah ozon. Kini terdapat kurang lebih 80 jenis alat ini untuk digunakan di seluruh dunia dalam mengukur jumlah ozon. Spektrofotometer Dobson mengukur ozon dengan membandingkan jumlah penyinaran pada jarak dua UV. Satu jarak gelombang terlacak kuat dengan ozon manakala yang satu lagi tidak. Perbedaan antara jumlah dua sinar secara langsung berhubungan dengan jumlah ozon.
Ozon sonde
Ozon sonde adalah sel elektrokimia dan penghantar radio yang dilekatkan kepada balon yang berisi gas hidrogen yang dapat mencapai ketinggian kira-kira 35 km. Udara dimasukkan ke dalam sel kecil dengan pompa. Pelarut dalam sel bercampur dengan ozon, menghasilkan arus eletrik yang berkadar sama dengan jumlah ozon. Isyarat dari sel diubah atas kode dan diantarkan melalui radio kepada penerima stasiun. Dari pelepasan balon hingga kegagalan, lazimnya kira-kira 35 km, sonde ini menyediakan taburan menegak ozon.
Tindakan dunia
Dalam tahun 1975, dikhawatirkan aktivitas manusia akan mengancam lapisan ozon. Oleh itu atas permintaan "United Nations Environment Programme" (UNEP), WMO memulai Penyelidikan Ozon Global dan Proyek Pemantauan untuk mengkoordinasi pemantauan dan penyelidikan ozon dalam jangka panjang.
Semua data dari tapak pemantauan di seluruh dunia diantarkan ke Pusat Data Ozon Dunia di Toronto, Kanada, yang tersedia kepada masyarakat ilmiah internasional.
Pada tahun 1977, pertemuan pakar UNEP mengambil tindakan Rencana Dunia terhadap lapisan ozon; dalam tahun 1987, UNEP mengambil Protokol Montreal atas bahan yang mengurangi lapisan ozon.
Protokol ini memperkenalkan serangkaian kapasitas, termasuk jadwal tindakan, mengawasi produksi dan pembebasan CFC ke alam sekitar. Ini memungkinkan tingkat pengunaan dan produksi terkait CFC untuk turun ke tingkat semasa 1986 pada tahun 1989, dan pengurangan sebanyak 50% pada 1999.
