If you aren’t worried about climate change, you aren’t paying attention

The normally-conservative IPCC gives us eight reasons to make action against climate change a top priority.

IPCC-WG2-SPMIf you still need a reason to join in the climate protests this coming weekend, here are eight.

The Intergovernmental Panel on Climate Change (IPCC) is a conservative body. It works by consensus, so its reports reflect the lowest common denominator − the least radical assessment of the evidence. As a result, since its formation in 1988 reality has almost always been worse than the IPCC’s worst case scenarios. Its descriptions of the climate crisis are dispassionate and emotion-free, almost boring.

So when the IPCC’s latest report on Impacts, Adaptation and Vulnerability (pdf) talks about “severe, pervasive, and irreversible impacts,” that’s equivalent to saying that we are bound for climate hell if we don’t act.

And when the same report lists eight key “RFCs” − Reasons For Concern about climate change, we should view them as RTBWATAFs  − Reasons To Be Worried And To Act Fast.

To be included in this list, a risk must involve “high hazard or high vulnerability of societies and systems exposed, or both.” In particular: “Identification of key risks was based on expert judgment using the following specific criteria: large magnitude high probability, or irreversibility of impacts; timing of impacts; persistent vulnerability or exposure contributing to risks; or limited potential to reduce risks through adaptation or mitigation.”

These Reasons for Concern were all “identified with high confidence” —

  1. Risk of death, injury, ill-health, or disrupted livelihoods in low-lying coastal zones and small island developing states and other small islands, due to storm surges, coastal flooding, and sea level rise.
  2. Risk of severe ill-health and disrupted livelihoods for large urban populations due to inland flooding in some regions.
  3. Systemic risks due to extreme weather events leading to breakdown of infrastructure networks and critical services such as electricity, water supply, and health and emergency services.
  4. Risk of mortality and morbidity during periods of extreme heat, particularly for vulnerable urban populations and those working outdoors in urban or rural areas.
  5. Risk of food insecurity and the breakdown of food systems linked to warming, drought, flooding, and precipitation variability and extremes, particularly for poorer populations in urban and rural settings.
  6. Risk of loss of rural livelihoods and income due to insufficient access to drinking and irrigation water and reduced agricultural productivity, particularly for farmers and pastoralists with minimal capital in semi-arid regions.
  7. Risk of loss of marine and coastal ecosystems, biodiversity, and the ecosystem goods, functions, and services they provide for coastal livelihoods, especially for fishing communities in the tropics and the Arctic.
  8. Risk of loss of terrestrial and inland water ecosystems, biodiversity, and the ecosystem goods, functions, and services they provide for livelihoods.

When the IPCC is concerned, the rest of us need to act. Now.

    Why is it that many socialist/marxist/communist groups pay lip service to stopping climate change and industrial agriculture, and yet at the same time call for the continued (industrial, westernized) development of the third world?

    I’m not knocking them, I’m actually curious.
