In the last times these two movements are attracting much attention in climate change.
Green New Deal is a strong political movement in USA. A couple of good explanations here: in New York Times and from Australia in Skeptical Science. USA and China are the two main economies David Appel likes it but he would prefer to separate climate change politics from other social politics. After reading it I partially agree but I prefer to connect with the next interesting movement.
On the other hand Greta Thunberg -the young girl that addressed the United Nations Climate Change Conference and in January 2019, having just turned 16, and was invited to talk to the World Economic Forum at Davos- has started and inspired a school strike against climate change. It has become a really strong young people movement worldwide and it deserves a post itself.
Both are important because have made mainstream climate change, both have helped feel the urgency of climate action that scientists are long ago explaining, both are reaching worldwide scope. At the same time they are different, Green New Deal is very political and School strikes are mostly social. Green New Deal comes from American politics and School strikes come from the cold northern Europe.
So I am very happy to hear in the news that climate change is a big problem and we have to act as humankind. This was really necessary both at political and social level. What I miss is concreteness in the message. It would be nice to focus on asking to close coal power stations, install yearly a good amount of renewables, support for governments speaking about end of fuel vehicles,… And it would be really great to ask a worldwide carbon tax that is one politics that would move many others. Concreteness is imperative as we need fast action.

Last year I haven written much about climate change. But I continue reading, thinking and worrying. It has been grey year, disappointing for many things and hopeful for others. So let’s put in black and white my personal balance:
In the most significant part I would locate the IPCC Special Report on 1.5ºC. It deserves more explanation, but the main point, in my opinion, is that scientific community concretes to the world the time limit to act in order to be in the safe side of climate change and the time limit is narrow. We are close to the crossroad
In contrast, the world CO2 emissions have increased significantly. And this is by itself the bad news, but considering the crossroad concept it gets even harder to assume, it is like saying something clearly to the world and getting the wrong answer immediately. This way there is no way. Last year was the 4th hottest until now but next record will be here soon.
COP24 did not get a political serious compromise and thermosolar is not growing fast either.
In the positive trends, there are many hopeful signals:
- Coal continues to decline in many countries and globally. Coal is the first fossil fuel to quit.
- UK in its brexit decision turmoil continues to be a great example, reducing power consumption (decoupling from economy), coal and emissions.
- Off-shore wind power seems to be a reality, in UK and in many other EU countries.
- Electric mobility seems closer. Maybe not in numbers but the felling is that some governments and auto industry consider it feasible. Or at least more feasible that ten years ago.
- Energy storage seems closer too. Battery costs go down steadily. This is a key factor to increase renewables in many electric systems.
- Photo-voltaic and on-shore wind power are profitable without subsidies in many countries. This changes the game, even more for developing countries. They do not have to decarbonize, just do not have to carbonize.
Most of those sentences deserve a dedicated post. I will try.
In the last couple of years my perception is is that climate change community is translating more and more the sense of urgency. Something has to be done but not tomorrow. This sense is applied to sea level rise, to the reasonable temperature limit, to extreme weather events, … In fact, changing the “acceptable” temperature increase limit from 2ºC to 1.5ºC is in itself quite stressing and makes climate change objective quite hard to achieve without immediate and strong international action. This urgent action need is becoming more and more general.
My felling about this urgency is a bit contradictory:
- I completely agree that we are not doing enough. Emissions have not start to decrease consistently, and there are more that 20 years now that climate change was widely recognized as one of the worlds leading challenges. Even worse, the required changes are societal and economic challenges that need strong commitment for a long time. The solution will not be fast.
- However, the urgency has a risk, some risks in fact. It can disturb the main long-term objective; it can distort the climate change history; and it can be very disappointing if no short-term success is achieved.
Maybe my felling is very related to the conflict between long-term and short-term in society, in my life and in climate change. Anyway, urgent action is needed, at least to start a long, difficult but necessary journey to reduce our greenhouse gas emissions and avoid too much climate change.
I have been quite absent from this blog last years but not from Climate Change news, so I dare to give an opinion about 2016. 2016 was the hottest year on record, it was confirmed by all agencies, NASA, NOAA, WMO,… It is true that “el Niño” effect helped a lot but breaking global temperature records in 2015 and 2016 confirms that Climate is changing and it is changing now and fast. And this, although expected, is really bad news because it means that we have less time left to reduce our CO2 (and some other GHG) emissions.

Maybe a positive influence is that skeptics do not know what to say after loosing their hiatus argument, they will come back with it in some time. Nevertheless they are happy because one of them in in the White House and nobody really knows how much he can hinder Climate Change fight (some even consider he can be positive). I think that having a man that doubts about climate change ruling the most powerful economy in the world in years that are critical to get a real and serious global climate agreement is, definitively, a problem.
To end positively, two important good news: a record new renewable energy capacity was added last year (with lower costs); and coal was passed by renewables worldwide. A good example is brexit UK coal use reduction, historical in the country that started industrial revolution with it.
Last days the most commented climate change news are the words coming from catholic church’s leader Pope Francis in a encyclica called Laudato Si. It is everywhere,
- in climate change webs it is celebrates and extensively commented: climate progress, carbon brief, skeptical science, quark soup…
- In skeptic webs it is criticized: whatupwhiththat, or this one.
- In general newspapers it is mentioned profusely. For example, New York Times has 22 news in their climate change channel last week (12-19th June), 17 are about Pope’s encyclica, including an editorial. relationship with poverty, american politics reactions, or critics to current global market. Many others like BBC, El Pais (in Spanish),… It is well described in this post.
- In Google a simple “Laudato Si” search gives 2.000.000 answers.
So,is this document a turning point in climate change? I agree with Carbon Brief‘s post that explains it is very positive and influential but just that. There are 1.2 billion Catholics in the world but the two great actors (USA and China) are not Catholic and most influential catholic states are among the “convinced” in climate change (Italy, Brazil, Spain). Even more, if this document is clear and with a lot of media attention, the opinion of catholic church with respect to climate change was not different with previous Popes. Nevertheless, in my opinion the three most positive points of the encyclica are:
- The moment is crucial. We need commitment and clear ideas in the governments and public opinion to start a way now that will avoid greater problems in 50 years. This document helps in this sense, to gain commitment. This year COP in Paris is a great opportunity to start a serious change.
- Many people in several western countries listens contradictory words about climate change, or they do not get a sense of urgency. The Pope will be a new word for them, as it is a highly respected opinion for many people and can help them inform more or get conscious about climate change. Every people’s opinion counts in this issue, at least to some extent.
- Finally Pope Francis connects the fact of the poorest with climate change. Climate change is becoming a great problem for them in many ways and this is the way it will become an humanitarian problem to the eyes of many people.
Last months I haven’t written anything in the blog due to a combination of lack of time in my personal life and spending my remaining “free” hours in coursera platform learning about climate change. It has been a very well spent time, I have learned many interesting things about climate change, but I hope to talk about it in a further post. Today I want to greet the new year with some short wishes about climate change:
1.- It would be wonderful to stabilize the carbon emissions worldwide as many important countries have done in their particular cases. Or even better, to start reducing them making 2013 the peak emissions year.
2.- If the previous is too optimistic, it would be good at least to stop Coal plant growth in most parts of the world.
3.- And combine it with a robust growth of renewable energies.
4.- An international carbon tax would really help, adopted broadly, or at least by the greater emitter countries. Next COP would be a good place to agree on it.
5.- If all of these does not happen, or it is too weak, and international social movement could help to raise public opinion awareness and move some reluctant governments.
6.- or … we could just stop talking and act with the seriousness to be expected from an intelligent being.
The tweet (more or less):
Climate change is real, induced by human emissions from fossil fuels and we have to act fast to avoid nightmare scenarios
Of course, this is a personal summary, far from the precise and scientific language of the report summary, but adapted to modern communication and fast to read. A very nice summary of the summary in 6 figures can be found in Carbon Brief. And with more or less extension or accuracy most newspapers mention it (some were even positively surprising for me). Skeptics employ several posts to counteract, in the last posts of WUWT, there are no less than 5 dedicated to that noble purpose, this shows its value.
However, with more or less coverage, my real worry is that I do not feel that the importance and urgency of the message has reach the world population, not in my close neighbourhood at least. And this is the 5th message in the same direction by an organization representing thousands of scientists. Or said in other words, even in many/most trust this scientific effort, it is not enough to act and make what can be done to reduce emissions drastically as needed.
