No Evidence for Unknown Source of Ozone Precursor

by P. Kollipara 21 September 20168 February 2023

A study suggests that known combustion and photochemical sources of nitrous acid, a precursor to ground-level ozone, are enough to explain levels seen in the atmosphere.

Climate scientists attending a climate science conference in Melbourne staged a lunchtime protest over restructuring and cuts to CSIRO staff and climate research programs.

When Predicting Drought Risk, Do Not Overlook Temperature

by P. Kollipara 15 April 201515 April 2015

Through analysis of 2014's record dryness in California, a study suggests that a risk of similar droughts depends not just on precipitation but also on temperature.
