Angeline M. Barrett is one of the CIRE staff on strike this week. In this article, she takes a closer look at how the USS pension is invested. This week, academic and some professional services staff at the University of Bristol will be on strike. The industrial action relates, amongst other demands, to the terms of our pension benefits and contributions . Bristol is the first UK University to declare a climate emergency and the School of Education has developed its own Climate Strategy. Yet, our pension fund, USS, holds substantial shares in the fossil fuel industry. Let us use the time on the picket lines to build a climate Ethics for USS campaign . USS investments in fossil fuels According to the USS 2019 annual report , 40.9% of the Pension fund’s £64.7 billion assets, what is known as its implemented portfolio, is invested in private equities (i.e. shares in private companies). Its website lists the top 100 equity investments (as of 31 March). Number one on the list is ...

Sub-tropical rainforest in China. Image credit: UMBRELLA project The East Asian monsoon covers much of the largest continent on Earth leading to rain in the summer in Japan, the Koreas and lots of China. Ultimately, more than 1.5 billion people depend on the water it provides for agriculture, industry and hydroelectric power. Understanding the monsoon is essential. That is why colleagues and I recently reconstructed its behaviour throughout its 145m-year history, in order to better understand how it acts in response to changes in geography or the wider climate in the very long term, and what that might mean for the future. Our study, published in the journal Science Advances indicates that the East Asian monsoon is much older and more varied than previously thought. Until quite recently the general consensus was that the monsoon came into being around 23m years ago , some time after the Tibetan Plateau was formed. However, we show that it has been ever present for at least t...

However, the relentless expansion of the industry is a major detriment to the environment on a local, regional and global level. This is due to the vast amounts of pollution produced from the jet fuel combustion process, that is required to propel aircraft through the air and to sustain steady level flight. Aircraft impact the climate largely through the release of CO2, which results in a direct contribution to the greenhouse effect, absorbing terrestrial radiation and trapping heat within the atmosphere, leading to rising temperatures. However, it is also vital not to overlook the non-CO2 aircraft emissions such as NOx, soot and water vapour, which result in alternative climate change mechanisms – the indirect greenhouse effect, the direct aerosol eff...

We've published a short video on air travel at the University of Bristol.  Here is a blog to accompany the video to give you more detail on the biggest issues that the university (and other similar organisations who rely on air travel) are facing as it works towards making itself carbon neutral by 2030.  Caboteer Eleni Michalopoulou, who features in the video, explains more... The effects of climate change now have almost a daily mention in the news as they become all the more frequent and evident by various studies, reports, blogs and pictures from all over the world. And as the climate crisis escalates, it was of course a matter of time before scientists pointed out the irony of flying to a conference in order to discuss the urgency and issues related to climate change. Of course, there is here an irony within the irony that led to a lot of finger pointing of scientists that do fly and a narrative of ‘unethical scientists’ that ‘ don’t practice what they preach ’...

Arctic Circle - the largest international gathering on Arctic issues. Image by Kate Hendry The Arctic is one of the most rapidly changing regions on Earth. Its lands and oceans are undergoing unprecedented transitions, from permafrost melting to sea ice thinning, and its people are vulnerable to the knock-on effects of climate change. At the same time, Arctic governments (state, regional and local) are looking towards the future of economic development, broadened participation and connectivity, and improved health and education. All of these socioeconomic and environmental challenges are going on against the background of a complex governance structure and heightened geopolitical pressures. Harpa, Reykjavik, the location of the Arctic Circle Assembly Unlike the Antarctic, there is no one treaty or agreement that underpins Arctic governance, which is instead reliant on the Arctic Council and a plethora of bilateral and multilateral agreements. The Arctic Circle is a no...
