Climate change

To coincide with the UN Climate Change Summit 2019 on September 23rd we highlight some striking climate-change related data visualisations we have seen across the Web:

Professor Ed Hawkins' warming stripes for 1850 (left side of graphic) to 2018 (right side of graphic). Progression from blue (cooler) to red (warmer) annual readings indicates long-term increase of average global temperature.

Fossil Fuel Emissions

The progress achieved in the last 60 years has come with a massive 400% rise in CO₂ emissions. All countries can take #ClimateActionNow to reverse this trend. See the link below for a striking animation from Carlos Razo - in particular, the dramatic rise in emissions from China since the mid-2000s.

CO₂ concentrations

Charles Keeling was instrumental in developing the technology to accurately measure CO2 concentrations in the atmosphere, and he began doing so in 1958 at the Mauna Loa Observatory. That 61-year record has proven to be the gold standard globally for measuring the rise in anthropogenic carbon dioxide. The “Keeling Curve” is a graph that vividly depicts how atmospheric concentrations of CO2 have shot upward since the mid-20th century.
