For the second year in a row, Dr. Geoff Pignotta has been honoured with a nomination as a 2020-2021 Favourite Faculty Member by the students in Residence at Carleton University. Students are asked to submit a nomination form for the overall favourite Faculty member. The survey simply states: Who is the faculty member and why are they so great?
We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 450℃ (the temperature of an oven’s self-cleaning cycle) and an atmosphere dominated by carbon dioxide (96 per cent) with a density 90 times that of Earth’s.
Prof. Richard Ernst, his master’s student and lead author Sara Khawja along with co-authors have published a paper in Nature Communications. This paper provides the first geological evidence in support of a dramatic climate change event on Venus.
