Mitigation vs Adaptation – Which path to follow under uncertainty?

Climate change poses a substantial risk to human societies. Indeed, as concluded by the first Lancet Commission on Climate Change and Health and reaffirmed by the second Commission report released this week, ‘climate change is the biggest global health threat of the 21st Century’. In economic terms, if we continue on our current path, the influential 2007 Stern Review concluded that we might experience costs equivalent to reducing annual global GDP by 5-20% ‘now, and forever’. As such, it is clear that action to prevent such impacts must be taken.


Capturing the opportunities for health through deep decarbonisation of the energy system

The Lancet Commission on Health and Climate Change strongly concludes that ‘tackling climate change could be the greatest global health opportunity of the 21st century’. This reflects the possibility to reduce air pollution, increase access to affordable and clean energy, and create more healthy urban environments while undertaking actions to reduce GHGs. The transition to a deeply decarbonised economy has to happen if we are to ensure a high probability of avoiding global warming of more than 2⁰C. But the opportunity to maximise the health benefits of such a transition should be grasped.


Tackling climate change improves health and saves money

One key message from the Lancet Commission is the fundamental health tenet that ‘prevention is better than cure’. Solving climate change now is far cheaper than the future responses which are likely to be required. The required actions also have many other benefits.

To reduce fossil fuel use, changes to healthier lifestyles are encouraged. That includes more frequent walking and cycling as well as shifting to diets which are less meat-intensive and more locally sourced.

People gain individually by being healthier. The health service gains by having fewer patients with preventable chronic ailments, reducing costs and workloads. Everyone gains through tackling climate change’s basic sources. (more…)

How does the IPCC know climate change is happening?

Climate change is one of the few scientific theories that makes us examine the whole basis of modern society. It is a challenge that has politicians arguing, sets nations against each other, queries individual lifestyle choices, and ultimately asks questions about humanity’s relationship with the rest of the planet.

The Intergovernmental Panel on Climate Change published its synthesis report on November 2 2014, a document that brings together the findings from the IPCC’s three main working groups. It reiterates that the evidence for climate change is unequivocal, with evidence for a significant rise in global temperatures and sea level over the last hundred years. It also stresses that we control the future and the magnitude of shifting weather patterns and more extreme climate events depends on how much greenhouse gas we emit.

This is not the end of the world as envisaged by many environmentalists in the late 1980s and early 1990s, but it will mean substantial, even catastrophic challenges for billions of people.
