“Global climate change” does not cause species extinctions

Contrary to what the media tries to make you believe, global climate change is not a major cause of species extinction. A recent study published in March 2019 in Frontiers in Ecology and the Environment shows that the major cause of extinction is the introduction of invasive alien species (IAS) into ecosystems. This phenomenon, well known to biologists and confirmed by the IUCN (International Union for the Conservation of Nature), is unfortunately little known to the general public.

Figure 1. Number of recent animal extinctions (IUCN categories “extinct” [EX] and “extinct in the wild” [EW]) for different groups of animals (figures from IUCN Table 3a). The colors provide information on the causes of the extinctions (“Driver”); for example dark purple is used for IAS (“Alien”), extinctions caused by local species (“Native”) are light purple. The category “Neither” includes other causes of extinction or unknown causes (source, Blackburn et al., 2019).



EIA AEO shows U.S. CO2 emissions 1 billion metric tons below 2007 peak in 2050

The Energy Information Administration (EIA) has released its 2019 Annual Energy Outlook(AEO) report for the U.S. showing that the nations year 2050 CO2 emissions will be just over 1 billion metric tons per year lower than its peak year 2007 CO2 emissions of 6.021 billion metric tons which retains and sustains the CO2 reductions achieved because of market driven increased use of natural gas while reducing coal fuel use.

During this same time period the world’s developing nations are forecast to increase their CO2 emissions by more than 14.5 billion metric tons per year bringing their CO2 emissions levels to a total of about 6 times those of the U.S.
