As you know there is a big meeting in Poland, some 200 nations, to talk about climate change, no to turn talk about climate change into actions.

The BBC produced 7 charts to show where we are which includes what each of us can do. There is a guide, too which you can tap and load down.

Included are temperature trends, the record setting year of 2018, where we are in meeting targets (need considerable improvement), the largest emitting CO2 nations (take a guess at the top two and then order them), climate risk to urban areas in terms of growth, and the state of arctic sea ice.

CBS This Morning devoted some time to an interview with John Urschel,  December 8. He really was a student-athlete, playing varsity football (lineman) at Penn State and playing it well enough to be drafted by the NFL's Baltimore Ravens in 2014.  

You gotta' love the way Urschel chose his university major and how it changed his view: "I majored in aerospace engineering at Penn State because my mother told me I was going to major in aerospace engineering," Urschel said. "I was good at math, I was good at physics. I didn't particularly love it but once I got to college I got to see math in a pure form." 

Before the NFL, though, he graduated in three years, staying at Penn State to complete two master's degrees. In this interview he describes how he "benched" mathematics to play professionally but realized that mathematics hadn't released its hold on his imagination and intellect so he played football and enrolled in a Ph.D. program in mathematics at the Massachusetts Institute of Technology.  He retired from football in 2017, after three years in the NFL. Urschel is aiming to graduate with his Ph.D. this spring.

In this interview Urschel talks about his life, his aims and hopes, and about breaking down stereotypes that surround minorities and college athletes. He closes with some useful advice. "If you have dreams, if you have goals, don't shut these things down. Don't fit into certain stereotypes. Don't think you can't have multiple aspirations," he said. "Life's too short. It's too short to settle and to live someone else's dream."

This CBS segment seemed less of an interview and more of a conversation between two people interested in the other and in the topic at hand which makes it all the more enjoyable and interesting. There is a lot here to chew on and also to be glad you know about.

Danish sculptor Thomas Dambo makes use of what he finds in "skips and rubbish tips" (dumpsters) to make gigantic trolls which he locates in woods and fields. You will notice that he uses a modified bicycle when collecting these materials.

The results may be seen here. I love these whimsical figures but then who doesn't love a troll (except on blogs).

A Proton's Last Moments

A proton in a short animation from Symmetry describes its final moments in the Large Hadron Collider.

You know the story. An atom consists of three particles: neutrons, protons and electrons.  Free neutrons are not stable; protons are (so far no one has ever provided evidence for their decay). And even if were to be observed no fundamental principles in physics would not be affected.  Neutrons decay into a proton plus some other stuff. Protons can be smashed, ripped apart, converted in energy as you will see. This is more complicated than I've described here so focus on the film.

About the Assessment

The Fourth National Climate Assessment was released by the Trump Administration on Friday night, November 23, an effort to bury it. Amy Kobuchar (D-MN) commented about this "news dump" on ABC's This Week, "They couldn't pick a day where they tried to get less attention on this report.  

The National Climate Assessment (NCA) is a 13-agency consensus document from the U. S. Global Climate Change Research Program (USGCRA) which was established by Presidential initiative in 1989 and mandated by the U. S. Congress in the Global Change Research Act (GCRA) of 1990 to develop and coordinate "a comprehensive and integrated United States research program which will assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change." The NCA is required every four years.

The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report (CSSR). Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods.

A Presidential Tweet


Before the Thanksgiving holiday, President Trump tweeted using his stand-by typical caps for emphasis, "Brutal and Extended Cold Blast could shatter ALL RECORDS - Whatever happened to Global Warming.?""Whatever happened to global warming," indeed. In short: it is a happening thing and it is going to get worse, much worse unless something is done now.   

Extracts

Before I include some extracts, Gavin Schmidt of RealClimate made some useful comments about the report, "The basic picture is utterly unsurprising, but the real interest in the NCA is the detailed work on vulnerabilities and sectorial impacts in 10 specific regions of the US.  The writing teams for those sections include a whole raft of scientists and local stakeholders and so if you think climate reports are the same old, same old, it's where you should go to read things you might not have seen before." Here are a few highlights from the NCA overview.

--Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future—but the severity of future impacts will depend largely on actions taken to reduce greenhouse gas emissions and to adapt to the changes that will occur. 

--However, the unambiguous long-term warming trend in global average temperature over the last century cannot be explained by natural factors alone. Greenhouse gas emissions from human activities are the only factors that can account for the observed warming over the last century; there are no credible alternative human or natural explanations supported by the observational evidence. Without human activities, the influence of natural factors alone would actually have had a slight cooling effect on global climate over the last 50 years

--High temperature extremes, heavy precipitation events, high tide flooding events along the U.S. coastline, ocean acidification and warming, and forest fires in the western United States and Alaska are all projected to continue to increase, while land and sea ice cover, snowpack, and surface soil moisture are expected to continue to decline in the coming decades.

--Without more significant global greenhouse gas mitigation and regional adaptation efforts, climate change is expected to cause substantial losses to infrastructure and property and impede the rate of economic growth over this century. ... However, the continued warming that is projected to occur without significant reductions in global greenhouse gas emissions is expected to cause substantial net damage to the U.S. economy, especially in the absence of increased adaptation efforts. The potential for losses in some sectors could reach hundreds of billions of dollars per year by the end of this century.

--Climate change has already had observable impacts on biodiversity and ecosystems throughout the United States that are expected to continue. Many species are shifting their ranges, and changes in the timing of important biological events (such as migration and reproduction) are occurring in response to climate change . Climate change is also aiding the spread of invasive species , recognized as a major driver of biodiversity loss and substantial ecological and economic costs globally.

--Ocean warming and acidification pose high and growing risks for many marine organisms, and the impacts of climate change on ocean ecosystems are expected to lead to reductions in important ecosystem services such as aquaculture, fishery productivity, and recreational opportunities. While climate change impacts on ocean ecosystems are widespread, the scope of ecosystem impacts occurring in tropical and polar areas is greater than anywhere else in the world.

--Many activities within the public and private sectors aim for or have the effect of reducing greenhouse gas emissions, such as the increasing use of natural gas in place of coal or the expansion of wind and solar energy to generate electricity. Fossil fuel combustion accounts for approximately 85% of total U.S. greenhouse gas emissions, with agriculture, land-cover change, industrial processes, and methane from fossil fuel extraction and processing as well as from waste (including landfills, wastewater treatment, and composting) accounting for most of the remainder. A number of efforts exist at the federal level to promote low-carbon energy technologies and to increase soil and forest carbon storage.

--Effective adaptation can also enhance social welfare in many ways that can be difficult to quantify, including improving economic opportunity, health, equity, national security, education, social connectivity, and sense of place, while safeguarding cultural resources and enhancing environmental quality. Aggregating these benefits into a single monetary value is not always the best approach, and more fundamentally, communities may value benefits differently.

--To help communities across the United States learn from one another in their efforts to build resilience to a changing climate, this report highlights common climate-related risks and possible response actions across all regions and sectors.

The Fourth National Climate Assessment may be found here. The guide to the report includes a discussion of key messages, description of climate assessment regions, what is meant by confidence and likelihood and a glossary.  There are some very useful diagrams and interactives included, e.g., Americans Respond to the Impacts of Climate Change and Indicators of Change.

Here is the link to the Midwest, our part of the world, which includes Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin.

David Attenborough's Message to COP 24

The UN climate change summit (COP 24*), 2-14 December 2018 in Katowice, Poland is certainly one of the most important meetings in the history of the human world although news coverage about climate change in general or this event in particular barely acknowledges climate or the importance of this meeting to the future of the planet. About 200 nations will be meeting with an aim to turn the vision of COP 23, Paris 2015 into action.

Climate scientist Katherine Hayhoe's summary of the U. S. 4th Climate Assessment written November 27 provides a bottom line that applies here:

It's real.
It's us.
Scientist's agree.
The impacts are already here and now.
But by acting now we can still avoid the most serious and even dangerous impacts.
Our future is in our hands.

Act now!  Continue acting in the short- and long-term future! Do something!

As The Guardian reports, David Attenborough was asked by the organizers of the conference to speak for all the world's people.  It is a message from the world's people to the leaders of the world. This is a daunting assignment. Attenborough made a two-minute talk which is linked in The Guardian article by Damian Carrington. It is a stirring presentation and includes many great quotes, e.g.,  Leaders of the world, you must lead. The continuation of civilisations and the natural world upon which we depend is in your hands. 

Carrington's Guardian essay includes some valuable links including one to a UN initiative especially for this conference, the ActNow Chatbot.
