Since records began in 1850, seventeen of the eighteen hottest years have occurred since 2000. Important steps on climate mitigation and adaptation have been taken over the past decade. However, these steps could now be regarded as equivalent to walking up a landslide. If the landslide had not already begun, then quicker and bigger steps would get us to the top of where we want to be. Sadly, the latest climate data, emissions data and data on the spread of carbon-intensive lifestyles, show that the landslide has already begun. As the point of no return can’t be fully known until after the event, ambitious work on reducing carbon emissions and extracting more from the air (naturally and synthetically) is more critical than ever. That must involve a new front of action on methane.
Disruptive impacts from climate change are now inevitable. Geoengineering is likely to be ineffective or counter-productive. Therefore, the mainstream climate policy community now recognises the need to work much more on adaptation to the effects of climate change. That must now rapidly permeate the broader field of people engaged in sustainable development as practitioners, researchers and educators. In assessing how our approaches could evolve, we need to appreciate what kind of adaptation is possible. Recent research suggests that human societies will experience disruptions to their basic functioning within less than ten years due to climate stress. Such disruptions include increased levels of malnutrition, starvation, disease, civil conflict and war – and will not avoid affluent nations. This situation makes redundant the reformist approach to sustainable development and related fields of corporate sustainability that has underpinned the approach of many professionals (Bendell et al, 2017). Instead, a new approach which explores how to reduce harm and not make matters worse is important to develop. In support of that challenging, and ultimately personal process, understanding a deep adaptation agenda may be useful.
