Real Climate just reported new peer reviewed scientific analysis from Canadian and British researchers that global temperature rise has in fact been greatly underestimated showing that the phenomenon of a so-called “warming pause” often raised by climate skeptics simply is not true. The most recent report from the Intergovernmental Panel on Climate Change reconfirmed that humans are causing climate change and that climate change is already impacting us. And the United Nations Environment Programme recently reported that business-as-usual especially with our continued dependence on fossil fuels, takes us further and further from what is safe in terms of the health of our climate.Christiana Figueres, executive secretary of the climate treaty repeated that “now is the time” to act in a recent speech. She is right. At Warsaw and at home, countries need to show how serious they are. We don’t have to push ourselves to come up with immediate actions that we can take. Countries don’t need to wait until 2015 to strengthen their targets for reducing climate-disrupting emissions. And we need to see consistency between our leaders’ statements about climate change and the impacts of their actual decisions. We need regulation of carbon pollution from coal-fired power plants and rejection of dirty energy infrastructure such as tar sands pipelines. We need rapid deployment of fuel efficiency, energy efficiency and renewable energy. Internationally, more countries need to commit to stop public financing of coal projects and to elimination of fossil fuel subsidies and elimination of the dangerous heat-trapping chemicals called hydrofluorocarbons (HFCs). Our blind adherence to business as usual when it comes to dependence on fossil fuels underlines that the real barriers to getting it right on climate change are political. At the same time that action to fight climate change is more urgent than ever, Australia put forward legislation to repeal the carbon price, remove renewable energy support, dismantle the independent Climate Change Authority and the Clean Energy Finance Corporation and undo support for a long term target of reducing carbon pollution by 80 per cent by 2050. And Canada, a country now driven by the tar sands oil industry, applauded them. Canada itself has already made it clear that it will not even meet its earlier commitments to reduce greenhouse gas emissions. Such climate contrary actions make leaders look out of touch with reality and irresponsible. Others are showing that clean energy makes economic and environmental sense. China is considering a cap on coal consumption. The United States has proposed limits on carbon pollution from new power plants. India is moving forward with innovative state building energy efficiency codes with support from developers. Chile has a new commitment to advance renewable energy, with a law requiring 20 per cent of national energy generation to come from renewable sources by 2025. Mexico has a climate change law. And Germany has moved to major investments in renewable energy infrastructure with renewable energy accounting for a little over one fifth of the country’s energy needs last year. These efforts show what is possible. Typhoon Haiyan and the urgent call for action from the Philippine delegation and many others has once again highlighted the urgency for climate action. The path is clear. What we need are leaders able to stand up to our business-as-usual dependence on fossil fuels and move us forward with clean energy.
