University of Michigan: “Migratory birds shrinking as climate warms.”
Since 1978, the University of Michigan has been collecting birds that died after colliding with buildings in Chicago. Body measurements were made for each specimen. 🐦
The study confirms that increase in temperatures lead to decrease in body size for birds. “Periods of rapid warming are followed really closely by periods of decline in body size, and vice versa.” The researchers suggest that body-size reductions are a response to climate warming and that increased wing length help offset body-mass losses.
70,716 birds measured
52 species (North American migratory birds)
4 decades (from 1978 to 2016)
Birds are getting smaller, their wings are getting longer as a response to warmer temperatures.
Science Based Targets Initiative (SBTi): “Companies with more greenhouse gas emissions than France and Spain combined reducing emissions by more than 35%”
285 companies responsible for more annual emissions than France and Spain combined are committed to reducing their emissions by 35%. That’s the equivalent for shutting down 68 coal fire plants.
SBTi is a voluntary initiative that aims to enlist private sector firms into global efforts to keep global warming below 2°C. More than 80% of companies that have pledged to reduce their emissions are based in developed countries. Well known brands include Coca-Cola, Daimler, Nestle, Nike and Microsoft. 🏭
Chief Executive Officer of Principles for Responsible Investments (PRI) fires second warning shot to Energy Agency (IEA) about rebadging of fossil fuel energy scenarios: “We urge you to do better”.
I was going to write just a couple of paragraphs on this, but ended with a full blog post providing some background to the bone of contention between two important players in the climate change arena (the Principles for Responsible Investments and the International Energy Agency).
