Stratospheric injection of solid particles could reduce climate change impacts
A new study shows that Solar Radiation Modification via Stratospheric Aerosol Injection (SAI) of solid particles could reduce some of the critical adverse effects resulting from the conventionally researched injection of gaseous SO2. For example, solid particles could reduce the impact on the North Atlantic Oscillation via reduced stratospheric heating.
Ocean cold period in the early 20th century less pronounced than thought
The oceans were less cold in the early 20th century (1900–1930) than previously thought. During this period the ocean appears too cold due to the way some measurements were taken. However, the new findings do not affect the quantification of the global warming relative to 1850-1900 and the human contribution to that warming, stress climate researchers around Sebastian Sippel (Leipzig University) and Reto Knutti from ETH Zurich.
These D-USYS researchers are the most cited
It's almost a tradition: Erich Fischer, Nicolas Gruber, Reto Knutti, Sonia Seneviratne and Johan Six are once again among this year's "Highly Cited Researchers". Congratulations to the award-winning researchers!
“Geoengineering will not solve the problem of climate change”
A team led by ETH climate researcher Sandro Vattioni has shown that diamond dust released in the atmosphere could be a good way to cool the climate. However, it is still not a sustainable solution to climate change, says Vattioni in an interview with ETH News.
The road to Net Zero is rocky, but feasible
A sustainable transition to a climate-friendly and biodiversity-rich Switzerland is only possible if we tackle the energy transition, climate change mitigation and biodiversity loss together. This will not be easy, but it is worthwhile and ultimately indispensable, says Reto Knutti.
20 Years of Atmospheric Physics Group WOLKE
The 20th anniversary of the WOLKE research group at ETH Zurich celebrated its significant impact on atmospheric physics over the past two decades. Led by Professor Ulrike Lohmann, WOLKE has become a leader in cloud microphysics, aerosol-cloud interactions, and climate research. The event at the ETH Alumni Pavillon gathered current members and alumni to reflect on the group's achievements and future.
Straight track from Zurich to Sofia
At the end of July 2024, ETH climate researcher Sonia Seneviratne travelled by train from Zurich to Sofia, Bulgaria, to attend the 61st plenary session of the Intergovernmental Panel on Climate Change (IPCC). She was able to stay ‘on the ground’ for her outward journey thanks to the commitment of her administrative assistant, Rahel Buri, who played a key role in organising Sonia's trip.
