Climate change is something that we hear about on a daily basis. The dire warnings tend to concern sea levels rising and temperatures varying so much that we have more intense and deadly storms than before, but these are all direct effects of the climate. Another thing that climate change can do is have indirect effects on organisms.
Organisms with complex life cycles spend the juvenile part of their lives in one environment before moving on to the adult stage in another environment. The researchers in this study wanted to know how simulated climate change during the juvenile stage of the organisms lifetime could affect the adult stage.
California is ablaze, again. So why is this part of the world so notorious for catching fire? (Image Credit: Daria Devyatkina, CC BY 2.0)
Recently, I was looking for skiable snow in central Norway when I bumped into a chatty Norwegian man. When I told him I was Californian, he asked why my state was always on fire. The story demanded vocabulary beyond my grasp of the language, so this story is for your benefit, my random friendly Norwegian. This is a story of resource mismanagement, of urbanization, Pocahontas, and a policy that was a bear’s favor.
As a fish ecologist living in Norway, it’s a joy to be able to travel to Melbourne and interact with the people that are driving forward fish science in my home country. So when I found out that the Australian Society of Fish Biology’s annual conference was taking place 3 days after my first flight home since 2016, I knew it was an opportunity I couldn’t pass up.
We’re on the last day of the conference at the moment, and over the next 2 months I’m looking forward to bringing you a number of insights, including interviews with guest speakers Eva Plaganyi and Gretta Pecl and pioneers of intriguing projects like Peter Unmack and Jarod Lyon. I’ll also have a fish edition of The Changing Face of Ecology, and some articles on how the angling community and the fish science community interact in a country with one of the most unique fish assemblages in the world.
The image of the lone polar bear has become almost ubiquitous in step with growing awareness of climate change. So why hasn’t the scientific community been able to convince the world to act accordingly? (Image Credit: Pixabay, CC0)
During the late 1970s, in the wake of intense scientific research showing that chlorofluorocarbons were leading to the depletion of the ozone layer, the world took action. By 1987, the world had seen the signing of the Montreal Treaty, which practically banned the use of CFCs, imposing significant economic costs on those who signed. Since then, the hole in the Ozone layer has retreated. It’s a powerful example of science identifying a problem, finding a solution, and then presenting both the urgency of both to the public. Scientific communication at its best, surely. So with recent steps backward in environmental conservation law worldwide, despite almost global consensus on the negative impact of well-studied worldwide environmental phenomena, is science communication no longer as effective?

Rapid warming is associated with population decline among terrestrial birds and mammals globally (2018) Spooner et al., Global Change Biology, DOI: 10.1111/gcb.14361
The term climate change is almost ubiquitous these days. Humans tend to concentrate on how the warming of certain parts of the globe will affect them, but the species we share the globe with also experience a myriad of effects at the hands of climate change. These include rising temperatures constricting the ranges of some species and concurrently extending the range of others, who can move into areas that were previously too cold for them.
Whilst the focus of climate change has often been on species range shifts, the effects on species abundances are less well studied. This paper attempts to quantify the effects of climate change on a large number of bird and mammal species, whilst accounting for other factors which could affect species abundances, like rates of land use by humans, species body size, and whether or not the animals are in a protected area.
When I interview ecologists, there are two themes I always end up gravitating towards; how the earth is changing and how to improve scientific communication with the general public. So when my colleague Stephanie Januchowski-Hartley mentioned she’d recently spoken to a global change ecologist who also happened to be a poet, I jumped at the opportunity.
Professor Madhur Anand is the co-author of Climate Change Biology and the author of A New Index for Predicting Catastrophes, a collection of poems which bridge the gap between poetry and science. Along her way to picking up two Canada Research Chairs and the ICCC Female Professional of the Year award, she has worked with theoretical physicists, poets and mathematicians. I spoke to Madhur about interdisciplinarity, using poetry to connect with the general public, and the future of the planet.
