Ocean May Absorb Less CO2 as Man-Made Carbon Emissions Are Cut
Shrinkage due to COVID-19 may provide case in point. Volcanic eruptions and human-caused changes to the atmosphere strongly influence the rate at which the ocean…
New Research Shows Half of the World’s Population Exposed to Increasing Air Pollution
Half of the world’s population is exposed to increasing air pollution, new research has shown. A team of researchers, led by Professor Gavin Shaddick at…
How Stimulus Dollars Are Spent Will Affect Emissions for Decades
To tackle COVID-19 and climate change, government spending must deliver jobs and growth alongside deep decarbonization. The COVID-19 pandemic and subsequent lockdowns have led to…
Volcanic Gases May Explain Long-Standing Puzzle About Rise of Atmospheric Oxygen on Earth
Oxygen first accumulated in the Earth’s atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues…
Islands Might Not Actually “Drown” As Sea Levels Rise – Here’s Why
Coral reef islands across the world could naturally adapt to survive the impact of rising sea levels, according to new research. The increased flooding caused…
