A 498 references paper on climate change and allergy

This is certainly the most comprehensive paper that examines the association of air pollution, climate change and allergen exposure. Air pollution and climate change are potential drivers for the increasing burden of allergic diseases. The molecular mechanisms by which air pollutants and climate parameters may influence allergic diseases, however, are complex and elusive. Certainly there … Continue reading A 498 references paper on climate change and allergy

A new animation of the famous HadCRUT4 climate dataset

 Download Here is the R sample code (PPT aspect ratio is 6:4, Youtube wants 16:9) . As ggplot2 animation packages have major difficulties to manipulate the single frames, I am combining here raw PNGs using ffmpeg.   In comparison here is the original circular plot. Would require blue, green, yellow, red in the Color … Continue reading A new animation of the famous HadCRUT4 climate dataset

Correlation of earth temperature and global mean CO2

For teaching I need CO2 time courses. For that purpose we can use the  Hadcrut 4 dataset created earlier Global mean CO2 mix ratios (ppm) can be found at https://data.giss.nasa.gov/modelforce/ghgases/Fig1A.ext.txt. After unscrambling that file and merging it to Hadcrut4 we can plot it Here are the two time courses while the correlation is higher than I expected   … Continue reading Correlation of earth temperature and global mean CO2

Johan Rockström talking about tipping points

Last week I had the opportunity to attend a lecture by Johann Rockström explaining his most recent Nature commentary about tipping points “too risky to  bet against”. The Intergovernmental Panel on Climate Change (IPCC) introduced the idea of tipping points two decades ago. At that time, these ‘large-scale discontinuities’ in the climate system were considered … Continue reading Johan Rockström talking about tipping points

Wie mit Wissenschaftsleugnern umgehen?

Hier eine Reihe von Link Tipps (eine Zusammenfassung aus der Scientists for Future Mailing Liste mit eigenen Ergänzungen). Fakten zählen leider hier wenig, dennoch die Sache ist nicht ganz hoffnungslos wenn man sich die Quellen ansieht, das ganze im Rollenspiel durchgeht, am besten einen Knopf im Ohr hat mit Supportern im Publikum. George Marshall. How … Continue reading Wie mit Wissenschaftsleugnern umgehen?

Climate crisis and cognitive dissonance

There is an interesting twitter thread by @Psychologists4F about news concerning the climate crisis and how we respond to the cognitive dissonance – the mental discomfort or psychological stress experienced by a person who holds contradictory beliefs or values. There are at least four possibilities how to respond to it Change the behavior (“reduce, refine, … Continue reading Climate crisis and cognitive dissonance

He Jiankui, a genome-editing researcher from the Southern University … Continue reading Der chinesische Menschenversuch

A crisis of purpose, focus and content

A Nature correspondence letter laments Universities are experiencing a crisis of purpose, focus and content, rooted in a fundamental confusion about all three. The crisis is all the more visible as their pace of social, intellectual and technological change falls increasingly out of step with that outside. Furthermore, universities are largely reactive where they should … Continue reading A crisis of purpose, focus and content

Open the window

Micro- and macroclimate factors certainly have more influence on our health than being reflected by current research. A new PLOS study now finds that facilities built more than 50 years ago, characterised by large windows and high ceilings, had greater ventilation than modern naturally ventilated rooms (40 versus 17 air changes per hour) … Old-fashioned … Continue reading Open the window
