In a world in which it’s still tough to convince many people that climate change is a very real phenomena, figuring out ways to tackle climate change is an even more difficult problem to wrap our heads around. In general, there are two strategies we can use: (1) mitigation (reducing the accumulation of greenhouse gases in the atmosphere) and, (2) adaptation (reducing the vulnerability of societies and ecosystems facing the impacts of climate change).
In my last piece (linked here), I wrote about the effects of climate change on forests. But what about the reverse, and their potential to mitigate climate change? Forests are crucial for climate change mitigation – they literally suck carbon out of the atmosphere. At the same time, forest adaptation will be necessary to avoid degradation of forest ecosystems due to a changing climate: an extremely complex task.

As carbon emissions rise globally, finding ways to reduce emissions and store carbon are coming to the forefront of modern science. Forests are huge carbon stores thanks to the copious amount of photosynthesis they conduct. As climate change increases temperatures, trees become a very important tool in the fight against rising emissions. One study even described forest restoration overwhelmingly more powerful than all other proposed climate change solutions. You might think: “So let’s go and plant trees!” Unfortunately, it’s not so easy.

With the world under so many anthropogenic pressures simultaneously, trying to come up with management solutions for different issues can be a problem. Climate change and biodiversity are a great example. Storing carbon is a great way to reduce the effects of climate change, and increasing the range of forests worldwide is a great way to increase carbon storage. Yet the sort of forests that store carbon most efficiently are often poor at promoting biodiversity. They are largely made up of very similar trees, while forests that include brush, scrubs, and other layers often store less carbon, but house more biodiverse communities.
As such, finding areas that are prime specimens for a) storing carbon and b) biodiversity conservation are incredibly important, so that managers at every level (from park rangers right up to the Intergovernmental Panel on Climate Change) can know where interests overlap, and adjust plans accordingly.

Environmental politics is a tricky business. We live in a world where environmental crises are at the forefront of the news cycle, and in which science is simultaneously becoming the subject of distrust. So it makes sense that at this point, politics should be adapting and evolving as science does.
So when Rasmus Hansson stopped by NTNU last month, Sam Perrin and I took the chance to sit down with him and see whether this was the case. Rasmus studied polar bears at NTNU in the 70s, before later becoming the leader of the World Wildlife Fund in Norway and then of the Norwegian Green party. We spoke with Rasmus about the transition from conservation to politics, the clash of ideologies and the future of environmental politics.

So often the effects of climate change are somewhat intangible to us; the weather may grow warmer, but it’s a slow and gradual process, which can seem entirely at odds with the alarm bells that things like the IPCC report seem to be constantly clanging. As such, demonstrating tangible environmental changes to a community whose livelihood may depend on such changes is a great weapon in the fight against the effects of a warming climate.
With this in mind, marine biologist Gretta Pecl founded the Range Extension Database and Mapping project, also known as Redmap. Redmap aggregates public sightings of fish to show shifts in the distributions of Australia’s marine species, including some that are crucial to our fishers. At the recent ASFB 2018 conference, I sat down with Gretta to talk about changes in marine species distributions, how they’ll affect Australia, and how they might help the public understand the effects of climate change.
