climate change policy, science, and activism; photography; cartography and mapmaking
Promoted by a recent Economist article on biodiversity and Alie Ward’s podcast on foresting ecology, I am trying out the iNaturalist app.
My outdoor pursuits mostly consist of walking at a steady pace for exercise, so plant and wildlife observations aren’t my priority. Nonetheless, it’s neat to be able to take a break anywhere in the city and use the map in the app to see what people have documented in the neighbourhood.
It seems that after a recent computer failure the Hubble Space Telescope is back online in a backup mode.
Canada is now promising the UN that it will cut greenhouse gas emissions to 40–45% below 2005 levels by 2030.
The government says emissions are already set to fall from 729 million tonnes (MT) in 2018 (the last year with final figures) to 468 MT by 2030.
Canada’s choice of a 2005 baseline sets it apart from the global standard of setting targets compared to 1990 emissions as required by the UNFCCC reporting guidelines, effectively forgiving 15 years in which bitumen sands output and Canadian GHG pollution rose substantially. Canada’s emissions rose from 600 MT to 747 MT between 1990 and 2005.
