Plants in the news 18 December 2015: The Paris Climate Talks (COP21)

Global temperatures since 1880. Zero is fixed at 1961-1990 average. (NASA).

COP21 was the 21st session of the Conference of Parties of the UNFCCC (United Nations Framework Convention on Climate Change). Its goal, which it achieved, was to get governments to agree to cut carbon emissions in order to limit global temperature rise.

A resolution was passed, in which the 195 countries present agreed on the goals of keeping global average temperatures below 2C above pre-industrial levels and pursuing the objective of zero net emissions (which involves both lowering the rate of emissions and removing greenhouse gases from the atmosphere). To achieve this goal, each country presented a set of Intended Nationally Determined Contributions that outline how they intend to decrease emissions. (In other words, not just to pledge a goal, but to specifically outline the path to that goal, through programs that each country deems most appropriate for itself).

Many see the COP21 agreement as important first step in curbing emissions of greenhouse gases (a good analysis of it is here and another one here). Although some feel that the promises are in inadequate and unenforceable (see for example this Opinion in the New York Times), the expectation is that COP21 is the start of a “virtuous cycle”, and as countries make these first steps they’ll gain confidence, expertise and will to formulate more ambitious goals when they next meet.

COP21 and plant science

Climate change affects plants. Warming temperatures and changing weather patterns are already affecting food production as well as ecosystems more broadly. Plant scientists are responding to climate change by working towards “climate smart agriculture”. (See for example the Global Alliance for Climate Smart Agriculture and this video from FAO). To ensure adequate food production in the future, agriculture has to adapt. Adaptation includes breeding plants for greater heat, drought, flooding and salinity tolerance, adopting new crops and crop varieties, and changing production methods (such as adopting drip-irrigation systems, promoting agroforestry, increasing yields and reducing post-harvest losses).

Plant scientists also can contribute to the goal of zero net carbon emissions. These efforts include reducing greenhouse gas emissions (for example by decreasing the use of energy-demanding nitrogenous fertilizers and reducing methane emissions from paddy rice), leveling fields to decrease the need pump irrigation water, and developing alternative, photosynthesis-based fuels.Picture3

 

Education, education, education

COP21 is a clear call for governments to support science. To meet the stated goals, improved technologies are needed, from renewable fuels to carbon capture as well as the myriad efforts to develop climate-smart agriculture. COP21 provides an exciting opportunity to educate students and communities about the importance of plant science, which provides the foundations of future food security and climate mitigation.

Numerous articles, datasets and infographics about climate change were published surrounding COP21. Here we’ve assembled some of these excellent resources, including some developed primarily for educators. Although the agreements have been signed, the hard work and the need to build public support is just beginning.

Celebrities and climate

Celebrity voices have impact, which you might find useful as you engage with the public on this important topic. Here are messages about climate change issued by: Arnold Schwarzenegger, Bill Nye (the science guy), David Attenborough, Han Solo Harrison Ford, Katy Perry, Leonardo DiCaprio, Pope Francis (“the most trusted figure in the US on climate change”), and Robert Redford.
