Atmospheric Carbon Dioxide Tagged by Source
“Carbon dioxide (CO2) is the most prevalent greenhouse gas driving global climate change. However, its increase in the atmosphere would be even more rapid without land and ocean carbon sinks, which collectively absorb about half of human emissions every year. Advanced computer modeling techniques in NASA’s Global Modeling and Assimilation Office allow us to disentangle… Continue Reading
Maps Distort How We See the World
Unchartered Territories: “Maps twist our perception of the world. Countries closer to the equator—which happen to be poorer —seem smaller than they are. This is because the world is a 3D sphere, but maps are 2D projections on a plane. That means distortion. So we develop a poor intuition for comparative region sizes. The biggest… Continue Reading
ShowYourStripes – visualizations tracking rises in global temperatures
ShoYourStripes: “These ‘warming stripe’ graphics are visual representations of the change in temperature as measured in each country, region or city over the past 100+ years. Each stripe or bar represents the temperature in that country, region or city averaged over a year. The stripes typically start around the year 1900 and finish in 2022,… Continue Reading
45 million people in the U.S. may be exposed to dangerous heat today
Washington Post Heat Tracker – “Extreme heat kills more people in the United States than any other weather hazard, and the risk of longer and more frequent heat waves is only expected to increase as climate change worsens. The Post is tracking the potential for dangerous heat this summer using the heat index, which accounts… Continue Reading
There Is Always An Alternative
Remarks presented to York University’s Faculty of Liberal Arts and Professional Studies Graduating Class of 2023 The human condition is…not good.

The Second Law of Thermodynamics is not up… Continue Reading
The data on 40 years of California wildfires is alarmingly clear
Quartz: “Wildfires in northern and central California increased fivefold between 1971 and 2021, according to a new study published by the Proceedings of the National Academy of Sciences (PNAS). The scientists behind the study found that those fires were mostly caused by anthropogenic climate change, the kind accelerated by human actions like burning fossil fuels… Continue Reading

Living Planet Report
“This year’s Living Planet Report is filled with ground-breaking figures, with most of the indicators describing a tremendous decline in ecosystem health. The calculation of the Living Planet Index shows an average 69% decline in population sizes of monitored mammals, birds, amphibians, reptiles and fish since the year 1970. Just as the R-number in epidemiology… Continue Reading
Visualizing Light Pollution
Axios: “Some stargazers have to travel more than 200 miles to see a sky devoid of light pollution. Why it matters: Dark skies are vital for the function of local ecosystems and our understanding of the universe. As light pollution grows each year, truly dark skies might get harder to find. By the numbers: The… Continue Reading
