Map of the United States (including Alaska, Hawaii and Puerto Rico), showing the mean annual temperature and the magnitude of the β coefficients from the obesity-adjusted meta-regression analysis, per state or territory over the period 1996–2009. The β coefficient from meta-regression analysis, representing the difference in diabetes incidence rate per 1 degree Celsius increase in temperature; red circles indicate a positive β coefficient, while blue circles indicate a negative β coefficient. Adjusted for the effect of time passage. Diabetes incidence rate is the age-adjusted diabetes incidence rate per 1,000. Image credit: Lisanne L. Blauw et al, doi: 10.1136/bmjdrc-2016-000317.

These graphs show carbon dioxide’s increasing greenhouse effect at two locations on the Earth’s surface, in Oklahoma and on the North Slope of Alaska; as the atmospheric concentration of CO2 (blue) increased from 2000 to the end of 2010, so did surface radiative forcing due to CO2 (orange), and both quantities have upward trends; this means the Earth absorbed more energy from solar radiation than it emitted as heat back to space.
