"Return your seat tray and seat back to the upright position. Lean forward, hands over your head. Feet flat on the floor. Brace for impact." All good advice if you're in an airliner facing an unscheduled return to Earth.
But what about climate change? How do we brace for those impacts? Fortunately we're finally getting around to thinking about the threats and how to respond to them.
There are a number of issues that need advanced planning and preparation. The big one is the replacement or reinforcement of essential infrastructure to ensure it can withstand a more demanding climate with severe weather events of increasing duration, frequency and intensity. Roads, bridges, floodways, essential utilities, the lot.
Then there's the problem of sea level rise, especially when it comes to populated areas most vulnerable to inundation and severe storm damage. You've got to figure out what you can defend and what has to be surrendered to the sea. Some people are going to be displaced and it takes a lot of planning to handle their relocation.
We don't pay a lot of attention to the health and healthcare impacts of climate change and yet they're huge. Extreme weather is very hard on people, especially the young and the old. In Britain they're raising the issue and demanding action from the political caste.
As extreme weather events such as flooding or heatwaves become more common, the UK Health Alliance on Climate Change urged ministers not to “wait for disaster” before acting.
The new alliance, made up of leading health bodies including royal colleges, medical faculties, medical publications and doctors’ organisations, called on the government to be “properly prepared”.
The group, launched on Wednesday, said the health service is ill-prepared for dealing with the effects of climate change such as the extreme weather seen this winter.
Where is Canada's national dialogue on climate change and health care? What are we doing to assess the threat and prepare to meet the near to mid-range needs of the Canadian people? This is not an area where you want to play catch-up. That costs lives.
Food security. In other countries they're addressing the problem at both domestic and international levels. This is a vastly bigger problem than the political attention it gets which is little to nil. We have all but forgotten the December, 2014 report of the UN Food and Agriculture Organization that warned most of the world's farmland will be severely degraded within just 60-years.
About a third of the world's soil has already been degraded, Maria-Helena Semedo of the Food and Agriculture Organization (FAO) told a forum marking World Soil Day.
The causes of soil destruction include chemical-heavy farming techniques, deforestation which increases erosion, and global warming. The earth under our feet is too often ignored by policymakers, experts said.
"Soils are the basis of life," said Semedo, FAO's deputy director general of natural resources. "Ninety five percent of our food comes from the soil."
Unless new approaches are adopted, the global amount of arable and productive land per person in 2050 will be only a quarter of the level in 1960, the FAO reported, due to growing populations and soil degradation.
Canada is not immune to soil degradation although we are in a better position than most. Yet there's a lot we can do to rehabilitate our farmland and prepare it for a harsher climate with more floods and droughts but we have to be proactive and it will take time.
There are so many threats we have to deal with - severe weather events, floods and droughts, invasive species, biodiversity loss - on and on. The time to begin formulating our strategy is now. We don't have the luxury of time to waste.
