    Always A Scientist

    Personal reflections at the end of a 15 year chapter in academic research science.
    ‘Scientist’ is usually the first word I use to describe myself, and that's probably because throughout my adulthood ‘scientist’ has been not only my job but something of an identity. Hence my exit from academic research this year has felt like a massive transition personally as well as professionally. But as much of a wrench as it has been to leave the lab bench behind me, the data, the evidence, my head and my heart are aligned on this one: in an era that will be defined by how we respond to compounding existential threats, it’s time to find a new way of being a scientist.

    Once a scientist...

    Scientific research can be such an incredible job to get to do. You’re tasked with observing, investigating and documenting a slice of the as-yet-unknown. You could well be the first – or even the only – person to witness or understand something amazing about the fabric of our world. It was surprisingly easy to lose that sense of wonder whilst immersed in competitive pursuit of the data, publications, funding and accolades that make it possible to keep climbing the career ladder in academia. But now, outside of that environment, I’m grateful to be able to look back with fondness on the tens of thousands of hours I spent planning experiments, tending to colourful flasks of assorted microbes, peering down increasingly fancy microscopes, developing those dreaded Western blots, then processing, analysing and sharing the insights this all generated. I’d really thought that my life in science would stay something like this until a comfortable retirement sometime in the 2060s. But about half a century ahead of schedule, its course started to look very different.  
    As a researcher studying malaria parasites and later similar types of environmentally-important ocean microbes, I’d felt motivated by the idea that we were making a meaningful contribution to improving lives and preventing suffering. But, catalysed by growing public concern about climate change in 2018, I’d found myself conflicted about the narrative that my research career was a noble pursuit, or something that would ultimately benefit humanity.  I’d started to ‘zoom out’ and see the wider context I was working within: one where thousands of scientists had clearly identified imminent, existential threats; one where transforming our societies is the only way to prevent their collapse… but where we’re still struggling to translate knowledge into the action needed to protect life on Earth. 

    Despite wide acknowledgement of the climate and ecological emergency, and despite rhetoric around environmental sustainability, very little about the culture and daily experience of working in research science was changing around me. It was an uncomfortable paradox that I felt badly equipped to navigate - the new ‘normal’ was, on the surface of it, to accept that we’re facing crises that will profoundly change our lives… whilst simultaneously continuing with our work pretty much unchanged by that knowledge (though perhaps paying a bit more attention to plastic recycling). I found this confusing, especially amongst the research community, who I’d assumed to be in a prime position to understand and respond to what the science was telling us. In their article No research on a dead planet my friend Dr Aaron Thierry and co-authors explore why this ‘double reality’ currently prevails: none of us are immune to powerful psychological incentives to minimise or suppress our knowledge and feelings about frightening information, but – vitally – we each do have agency and opportunity to overcome these barriers and start to play a role in creating necessary, transformative change in our systems, institutions and societies. 

    For me it was feelings of fear, despair and isolation – not of duty nor agency – that first led me to find community as part of environmental social movements. I was especially drawn to spaces where scientists were organising, and all I’ve learned there has evolved my perception of what a scientist’s role could or should be in the 21st century (summarised here and potentially the subject of a future blog post). It empowered me to be braver, to explore how a scientist can make a positive impact within and beyond their job. So, alongside making various transitions in my lifestyle and research direction, I began, initially tentatively, to talk much more openly about the disruption of Earth’s life-supporting systems, my fears and feelings about what that meant for us, and my experiences of taking action in response.  At work I attempted to start conversations about how academics might support and accelerate positive transformations, to activate people in leadership positions, to push for accessible and impactful environmental education and to build networks. Beyond the lab, I found many other avenues where a science background together with experience in advocacy and activism could be usefully combined; from facilitating workshops in my local community to amplifying scientists’ warnings through campaigning and direct action.

    ... always a scientist?

    Overall I’ve been very fortunate to have had a positive experience in moving from knowing about to acting upon the climate and ecological emergency.  The reactions of colleagues, friends, family and the wider public along the way have largely been encouraging and motivating,  though there have been challenging complexities, tensions and occasional hostility. Amongst the more painful have been in recognising and attempting to counter the inertia that persists within academia – a home I had, maybe naively, thought I’d be effectively-placed to help activate from within. Like many scientists I’ve had the pleasure of interacting with (including the authors of these calls-to-action), I still believe in the potential of the scientific research community, and of universities in particular, to foster and adapt to rapid change in our environment and societies.  However, my own attempts to cultivate engagement and action have felt much less constrained – and ultimately more effective – where I’ve been working outside of any academic role, instead acting as a scientist in wider society. 
    The work I now prioritise focuses on exactly that; bringing the most essential science out of academic silos and into the places it needs to be understood and acted upon. In 2024, those included public and community spaces, local and national government, and, via an innovative educational start-up, some of the world’s biggest corporations. I don’t feel any less a ‘scientist’ having made a leap out of the research spaces that had become comfortably familiar.  I’m still discovering, learning, experimenting, analysing and communicating, only now I use different methods in different environments to better align my actions with addressing broader, more urgent questions and challenges. I miss the lab, the students, the microbes and the associated moments of awe that were part of my life as a more traditional academic scientist, but I’m excited by the opportunities and impact that are already part of this new chapter.

    Explain the Emergency … in 10 minutes?

    I’m often asked to give an overview of the science of the climate and nature emergency in something like ten minutes…. and this is no small task. How can we capture the interconnected threats to life on Earth, conveying the vast scale and the urgent, urgent need for transformative action?  How can we do that for audiences that we don’t know much about, who may not have had the opportunity to think very seriously about these difficult subjects before? How can we do that in a way that tells the whole truth but doesn’t throw those who hear it into a state of overwhelm, denial, or despair… but instead empowers and motivates?  Is it possible to do this in ten minutes??? 

    It feels important to try, and to find out!  So I’ve challenged myself to sit down for just one hour and write down what I think are the absolute core things - without getting distracted by the details however important they are/feel - that any person needs to know to start on their own journey from knowing to acting. It won’t be polished, it won't be perfect - but it can form the basis of something that can be tested and refined. It’s what I know and communicate all the time, so I should have the really core message at my fingertips, right?  It feels daunting nonetheless, but here goes….

    Our  Climate  &  Nature  Emergency:  the  bare  essentials

    If there were just a few key things I wish as many people as possible would know, but also feel about the climate and ecological emergency… they would be something like these:

    The threats are massive and widely underestimated. 
    Humans face escalating fires, floods, food shortages and consequent health and societal crises. 


    It’s happening NOW,
    having a devastating impact on millions of people and countless other species around the world already.


    The impacts will get worse,
    and are likely to do so 
    very rapidly. Every person and every species will experience those impacts. 


    This is extremely unfair 
    globally, socially and intergenerationally. 


    Current actions are nowhere near enough
    We need to transform our mindsets and systems if we are to secure a liveable future for ourselves, for future generations and for other species. 


    We can make a difference 
     but only if we act now and act together


    Here is a brief summary of what I mean by each of these…

    The threats are massive, and widely underestimated
    • We know the Earth is heating up, and it’s heating faster than it has done since the human species evolved. Science is clear that this is a direct result of greenhouse gas emissions, caused predominantly by human activities such as burning fuels, agriculture  and chemical use.
    • In parallel the ecosystems that regulate our climate and that we are dependent on for essential food and resources, continue to be destroyed. Humans have radically changed the land - clearing forest, degrading soils, polluting the water air and beyond. Species are going extinct over a thousand times faster than would be expected otherwise. 
    • These effects combine to threaten the existence of every species on Earth, for example through heatwaves, fires, floods, storms, food scarcitydisplacement and conflict.
    • It can be easy to feel like these threats aren’t as bad as they are, especially when we don’t see many leaders, or even the scientists studying these threats, acting proportionate to their own warnings. 

    It’s happening now.  
    • Since humans began shaping the land on a global scale, we have been destroying irreplaceable ecosystems and disrupting the finely balanced functioning of the wider Earth system.  
    • We have already seen direct impacts such as the loss of wild places and species, and there being hotter and less stable climate, and we are now seeing the knock-on effects on humans. 
    • There are so many examples that it’s hard to find the ‘right’ record shattering heatwave, raging wildfire, or heartbreaking famine or conflict to highlight. As I write this I’m hearing about the deadly flooding in Valencia, Spain after ‘almost a year’s worth’ of rain fell in a single day.

    The impacts will get worse
    • The worst effects of the harm already caused are yet to be seen; they take time to unfold… there is a delay between the cause and the full impact. Just one example I think about often is that, even with immediate radical climate action, entire island nations and major population centres will still likely be submerged due to sea level rise by the end of the century. Low-lying coastal cities - London, Los Angeles, Rio and many more - may not remain defendable in my own lifetime. 
    • The essential systems that we need to survive on this planet are so incredibly interdependent. Disruption to one part of one of those systems has cascading impacts over time -  imagine the cascading impacts on a food web if the organism at the base of it is wiped out. 
    • Worse, we know that nonlinear phenomena involving feedback loops and tipping points can massively accelerate warming and the breakdown of ecosystems.  We know we are perilously close to triggering major irreversible changes of state in our Earth system…  but we do not know exactly how close…or if we have already done so.

    This is extremely unfair 
    • The people most responsible for causing and exacerbating these threats are very different to those who are most immediately and most badly impacted by them.
    • This injustice compounds existing global and social inequalities, for example between countries, wealth levels and generations. 
    • A small number of people and organisations have personally profited from knowingly making this predicament worse and/or spreading misinformation to delay action to address it. Despite the now widely accepted science about the climate and ecological emergency, this continues in constantly evolving forms. 

    Current actions are nowhere near enough. 
    • This section could easily turn into somewhere between a rant and a scream so I’ll keep it extremely brief:  despite talk and advertising suggesting otherwise, it’s hard to think of any examples of governments or major corporations that are acting in line with what science is clear is necessary, or even their own (usually also inadequate) pledges. 
    • Our conversations need to transform from action being about doing incrementally-less-harm-than-we-used-to (e.g. slightly reducing the deforestation/emissions/exploitation we cause year by year) to actively making things better (i.e. regenerating and restoring)

    We can make a difference 
    • There are some frightening changes that are now essentially locked-in… but we, collectively, have a choice about how bad, how rapid and how unfair we allow what happens next to be. 
    • What can we do? In a nutshell: 
      • End the extraction, destruction and pollution we have become so accustomed to.
      • Repair, restore and regenerate the natural systems that enable and support life to thrive.
      • Communicate and collaborate to empower and accelerate action. 
    • Individualised action has an importance, but we are so much more powerful when we act together.  By influencing the systems, structures and cultures we operate within, we make it easier for one another to take more effective action. 
    • We often underestimate others’ level of care and willingness to act - it’s hard to be the ‘first’ to speak up or try something different, it can also feel scary to get behind that first person when they do (even if you’re fully with them in spirit)... but when we are brave enough to show our willingness and our courage we build momentum, we build movements, we build hope and we create change.  

    So those were the words that flowed onto a blank page when I gave myself an hour to get them out.  I gave myself an hour… I took almost two. But I know if I hadn’t set that intention I would otherwise have obsessed over referencing and phrasing and would have been less likely to home in on the absolute essentials. I intend to look at this with fresh eyes, perhaps add some visuals (and maaaaybe even a reference or six) to make it more engaging and useful to anyone who reads it.
