Overwhelmed & Discouraged: The latest IPCC report


I’m feeling pretty deflated this today, I’ll admit. Deflated and frustrated.

It’s taken me a while to write this today, partly because there’s so much to read through, partly because it makes for such depressing reading, and partly because I can’t help but listen to this negative little voice that’s telling me that it’s pointless to even bother. Because people and nation states are still not going to change. You look at the Australian government right now, and then you look me in the eye and tell me seriously that Australia is going to kick off some real, meaningful action to reduce our emissions. You drive through Texas and tell me that all these people are going to give up their trucks, reduce their air-conditioning usage. Look at mining and gas companies and tell me that they’re going to look at ways of shifting across to green energy. Look at China and India and tell that they’ll put their industrial and economic development on ice, because those of us in developed countries (which have caused the problems in the first place) are asking nicely.

It’s not going to happen. And if it ever does, I can’t help but feel it will be right at that tipping point, where it’s already too late.

I’m sorry for being such an enormously melodramatic negative Nelly, but the enormity of this problem is starting to overwhelm me. With each IPCC report that comes out, the outlook looks bleaker and bleaker. A few quotes from the latest report on what has already happened:

In many regions, changing precipitation or melting snow and ice are altering hydrological
systems, affecting water resources in terms of quantity and quality

Based on many studies covering a wide range of regions and crops, negative impacts of
climate change on crop yields have been more common than positive impacts…Climate change has negatively affected wheat and maize yields for many regions and in the global aggregate.

Impacts from recent climate-related extremes, such as heat waves, droughts, floods,
cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems
and many human systems to current climate variability (very high confidence). Impacts of
such climate-related extremes include alteration of ecosystems, disruption of food production and water supply, damage to infrastructure and settlements, morbidity and mortality, and consequences for mental health and human well-being. For countries at all levels of development, these impacts are consistent with a significant lack of preparedness for current climate variability in some sectors.

Of course, countries are trying to adapt to these new effects, but the description of these adaptations worldwide is just a half a page. Seriously. We are already feeling the effects of climate change worldwide, and our best efforts regarding adaptation can be summarised in a half page. The predictions for the future of climate change don’t offer us much promise unless we get ourselves into gear in terms of both prevention and adaptation though – again, some choice quotes:

Throughout the 21st century, climate-change impacts are projected to slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing and create new poverty traps, the latter particularly in urban areas and emerging hotspots of hunger (medium confidence).

A large fraction of both terrestrial and freshwater species faces increased extinction risk
under projected climate change during and beyond the 21st century, especially as climate
change interacts with other stressors, such as habitat modification, over-exploitation,
pollution, and invasive species (high confidence)

Until mid-century, projected climate change will impact human health mainly by
exacerbating health problems that already exist (very high confidence). Throughout the
21st century, climate change is expected to lead to increases in ill-health in many regions
and especially in developing countries with low income, as compared to a baseline without
climate change (high confidence)

Reading through the report has left me overwhelmed. Eric Holthaus summarises my feelings beautifully in this paragraph from his article in Slate:

It’s difficult for me, as both a scientist and as a human, to emotionally process continued inaction on climate change. My characterization of this report may make it seem like the problem is hopeless. It’s not. There’s still time to stave off most of the worst effects if we all work together and realize that every single person’s actions, no matter how small, make a difference. But it will take massive action.

My greatest fear? We’re still not ready for the necessary ‘massive action.’
