To limiting global warming by 2 degrees is not an option. In order to avoid rampant climate change we need to limit global warming by 1.5 degrees. We can not rely on negative emission technologies and have to take equity and justice into account.
The IPCC rapport describes the enormous difference between 1.5 and 2 degrees global warming. As the average global temperature increases, so does the risk of triggering so called tipping points, which will cause the earth to move from self-regulating to self-heating. Learn more by listening to professor Will Steffen in his lecture at the Climate Students Sweden’s conference in Mars 2019.
The 2 degree goal requires a reduction in industrial countries of 15 percent each year starting 2017. More than two years without such reductions have now passed, which is why we are aiming for 1.5 degrees and demanding a higher tempo. Learn more in this presentation (10.19 minutes in) by professor Kevin Anderson in 2017.
The time to reduce emissions is now. In order to avoid a global warming of 1.5 degrees, with a 66 percent chance of success, only two years remain with the rate of emissions described in 2017, according to the Carbon Brief analysis.
UN Environments Emissions Gap Report 2017: “The overarching conclusions of the report are that there is an urgent need for accelerated short-term action and enhanced longer-term national ambition, if the goals of the Paris Agreement are to remain achievable” (s. xiv).
Climate equity means that countries who have historically generated a lot of greenhouse gases should reduce their emissions at a quicker rate than countries who have not. It also entails that countries who can reduce emissions faster than others, should do so. This is included in article 2.2 of the Paris agreement
We can not rely on technologies that do not yet exist at scale, nor ones who hold future generations responsible for resolving this mess. We take responsibility and act for quick emission reductions now. Watch professor Kevin Anderson explain the problem with negative emissions technologies in this video (33 minutes in) and in this article.
