The Environment / Global Warming

  • Can We Fix Climate Change With Technology?

    A report from the National Academy of Sciences concluded that experiments in blotting out the sun in order to reduce the amount of the sun’s rays that hit the Earth would be too risky. Spraying aerosols into the atmosphere – one leading approaching to “geoengineering” – would be a massive science experiment that would have unknown environmental side effects. The fallout on precipitation patterns, agricultural productivity, and the global climate cannot be fully known until it is unleashed. If the United States seeded the atmosphere with aerosols that produced more drought in, say, sub-Saharan Africa, that would potentially raise indefensible…

  • China Ramps Up Emissions Efforts With New Carbon Market

According to the South China Morning Post, Jiang Zhaoli, a senior official with National Development and Reform Commission’s (NDRC’s) climate change department, said that China plans to initially cap emissions from six industrial sectors. These include power generation, metallurgical, nonferrous metal, building materials, chemicals, and aviation. “We hope to kick off the national market in summer…

  • Big Oil Going On The Offensive

    Carbon Counterattack:  How Big Oil Is Responding to the Anti-Carbon Moment Around the world, carbon-based fuels are under attack. Increasingly grim economic pressures, growing popular resistance, and the efforts of government regulators have all shocked the energy industry. Oil prices are falling, colleges and universities are divesting from their carbon stocks, voters are instituting curbs on hydro-fracking, and delegates at the U.N. climate conference in Peru have agreed to impose substantial restrictions on global carbon emissions at a conference in Paris later in the year. All this has been accompanied by what might be viewed as a moral assault on…

  • What If The World Can’t Cut Its Carbon Emissions?

    Many people, including more than a few prominent politicians, accept that global warming must be limited to no more than two degrees C above the pre-industrial mean, or a little more than one degree C above where we are now, to avoid dangerous interference with the Earth’s climate. Let’s assume these people are right, that the 2C threshold really does represent the climatic equivalent of a cliff and that bad things will happen if we drive off it. So how do we apply the brakes? According to the IPCC by limiting cumulative future global carbon emissions to no more than…

  • Poor Countries Don’t Care About Climate Change

    The Lima climate talks have just ended. Predictably, no substantive agreement was reached. The nations of the world agreed for the umpteenth time that climate change needs to be fixed but remained completely unable to agree as to who should pay for fixing it. For the umpteenth time the rich developed nations said it’s a global problem and everyone should pitch in. For the umpteenth time the poor developing nations said no, you rich guys caused it and should therefore pay to fix it, and besides there’s a clause in the original 1992 UNFCCC agreement that lets us off the…

  • The $17.6 Trillion Solution To Climate Change

    This week, the world's leaders are gathering in Lima, Peru for the UN Framework Convention on Climate Change, where they hope to put together a plan for cutting global emissions that will slow the inexorable warming of the planet. The convention follows a deal reached last month by the United States and China - the globe's top two polluters - to cut their emissions. For China, this means capping its emissions at whatever rate they hit in 2030, while the U.S. pledges to reduce its emissions by 26 to 28 percent of its 2005 levels by 2025. Before we all…

  • Latest IPCC Findings Undermine Climate Change Claims

    Working Group 2 of the Intergovernmental Panel on Climate Change recently released the final version of its contribution to the IPCC Fifth Assessment Report: Climate Change 2014: Impacts, Adaptation, and Vulnerability. The WG2 report contains 1,731 pages of text, figures, boxes, footnotes and references, the first 832 of which list every negative impact climate change is having or could conceivably have on the Earth, its physical state, its ecosystems and the people who populate it. I doubt that anyone has ever read it from beginning to end. I certainly haven’t. But the report’s mind-numbing length hasn’t stopped people from interpreting…

  • China’s Emissions Could Negate Global Efforts Against Climate Change

    Which contributes more GHG to the atmosphere, red or white? Image credit: Greg Baker for the NY Times, In yet another global greenhouse gas (GHG) emissions reduction development – of which there have been several in the last few weeks and months – US President Barack Obama and China President Xi Jinping came together over some white and red wine, respectively, to set another arbitrary goal with few accountability measures in place. (Obama, perhaps still reeling from his post-midterm-election headache, apparently wants to avoid the tannins if he can.) But back to the US-China climate accord. The “How-Big-a-Percentage-Reduction-By-When” game went…

  • China And US Agree Ambitious New Emissions Deal

The United States and China, the world’s two biggest contributors to climate change, have struck a new, more ambitious deal to cut their greenhouse gas emissions. President Barack Obama and President Xi Jinping jointly announced the deal Wednesday morning, the New York Times reported. The agreement marked the culmination of nine months of quiet dialogue between the two countries, capped off in recent days by Obama’s…

  • Who Stands To Benefit From Climate Change?

    The Intergovernmental Panel on Climate Change (IPCC) released their synthesis report Sunday, Nov. 2nd. The report combines the Panel’s past work and reiterates the near unanimity in the scientific community regarding the man-made role in global climate change. Still, public and political perception is very much divided and the report aims to lay the foundation for a new global treaty on climate change by the end of next year. Stark in their assessment, the IPCC posits a grim future in the absence of any meaningful mitigation. Not all change is bad however, and, when examining the energy implications, global climate…
