How do we deal with the carbon dioxide problem? Scientists have created a guanidinium sulfate salt that can capture & store CO2 at ambient pressures & temperatures. The strategy could change how industry captures, transports & stores the gas #geochemchat

Temperatures in the world’s oceans have broken fresh records, testing new highs for more than a month in an “unprecedented” run that has led to scientists stating the Earth has reached “uncharted territory” in the climate crisis. https://t.co/c5jhU5JbB0

Do you know what ENSO is? This phenomenon has a major influence on summer rainfall variability in South Africa. El Niño conditions are expected to return later this year so expect widespread drought in SA! ☀️🌡️

@Matthew1866730 More relevant to southern Africa, can geochemistry help in reconstructing cyclone history? Freddy is the longest lived cyclone on record. How will things change in the future…#geochemchat

How is anthropogenic Pb distinguished natural sources of Pb? #geochemchat

[zama22 @swazi2212]

Here's an interesting read about the decline in lead pollution in the Atlantic ocean. This Pb pollution occurred due to human activities. It also explains how the sampling was done.
