World Scientists’ Warning of a Climate Emergency (Condensed Version) 

William J. Ripple, Christopher Wolf, Thomas M. Newsome, xxxx scientist signatories from xxx countries 

We scientists have a moral obligation to clearly warn humanity of any great existential threat. In this paper, we present a suite of graphical vital signs of climate change over the last 40 years. Results show greenhouse gas emissions are still rising, with increasingly damaging effects. With few exceptions, we are largely failing to address this predicament. The climate crisis has arrived and is accelerating faster than many scientists expected. It is more severe than anticipated, threatening natural ecosystems and the fate of humanity. We suggest six critical and interrelated steps that governments and the rest of humanity can take to lessen the worst effects of climate change, covering 1) Energy, 2) Short-lived pollutants, 3) Nature, 4) Food, 5) Economy, and 6) Population. Mitigating and adapting to climate change entails transformations in the ways we govern, manage, feed, and fulfill material and energy requirements. We are encouraged by a recent global surge of concern. Governmental bodies are making climate emergency declarations. The Pope issued an encyclical on climate change. Schoolchildren are striking. Ecocide lawsuits are proceeding in the courts. Grassroots citizen movements are demanding change. As scientists, we urge widespread use of our vital signs and anticipate that graphical indicators will better allow policymakers and the public to understand the magnitude of this crisis, track progress, and realign priorities to alleviate climate change. The good news is that such transformative change, with social and ecological justice, promises greater human wellbeing in the long-run than business as usual. We believe that prospects will be greatest if policy makers and the rest of humanity promptly respond to our warning and declaration of a climate emergency, and act to sustain life on planet Earth, our only home.

Voluntary actions in conservation - a dream or reality

Torstai 21.6.2018 klo 9:50 - Mikko Nikinmaa

In many cases it is said that environmental actions can be voluntary, that people themselves see if they are required or not. This is wishful thinking. Environmental actions are needed and can be done as long as it is other people doing them, no the persons themselves. Just as an example, a scientific conference of environmental scientists gave a possibility of paying a fee for the carbon footprint caused by travelling to the conference. The fee was at three different levels. Of the environmental scientists only approximately 40 % paid any fee at all, and virtually everyone who paid, paid only the lowest fee, although it was much less than can be estimated to be the environmental cost of travelling. And this was a group of environmental scientists!!!

If the general public is even less concerned about the environment, the noble principle that people voluntarily consider what their actions mean to the environment, and in case they cause deterioration of one aspect, other actions are done to remedy the damage (in another environmental dimension). Consequently, one can probably only get things done by environmental taxes and giving reliefs of them to people, who can demonstrate that they are carrying out environmentally beneficial actions. The taxes are needed, as otherwise people do not take the environment into account. However, probably more can be achieved by having incentives giving a financial benefit for good deeds to the environment.

In view of the above, I bow deep to the individuals who do important deeds to help the environment without expecting anything in return.
