Panama caps its ships, Washington cuts the Colorado. Nobody is preventing this weather now - they are paying for it.

Panama will cap crossings as El Nino dries its lakes, and Washington has cut three states' Colorado water by 21%. Both are coping with weather that has already arrived - the half of the work that gets a fraction of the money.

Where this points

Watch the Gatun and Alajuela lake levels into the autumn - the canal says it may tighten the cap again if they keep falling. [1]

Full briefing

Two of the waterways that move the world’s food and fuel began rationing this week, and the reason was the same in both places. The rain did not come.

Panama’s locks are gravity-fed and run on fresh water. Every crossing spends millions of litres out of two man-made lakes, Gatun and Alajuela. El Nino warms the Pacific, which weakens the winds that carry rain to Panama, so the lakes fall. The only lever the canal really has is fewer ships [1]. Two years ago that lever went as low as 22 crossings a day, and one tanker paid more than $4m to jump the queue [1]. Washington’s Colorado decision has a different cause and the same shape. Three states lose about a fifth of their water, the four upstream states lose none by order, and Arizona has threatened to sue [2]. California’s river commissioner called the deal “a bridge, not a permanent solution” [2].

None of that is prevention. It is management of weather that has already landed, and that work is funded at a fraction of the work aimed at the next lot. A Reuters Breakingviews column puts Europe’s planned adaptation spending near 69bn euros a year to 2050, against clean-energy investment of almost 700bn a year in the 2030s [4].

The two figures quoted most this week do not measure the same thing, and the gap between them is the story. Moody’s puts last summer’s European heat at roughly 43bn euros of lost economic output and only about 500m euros of insured payouts [4][5]. The first counts activity that never happened. The second counts claims paid. Heat breaks almost nothing, so most of the loss never becomes a claim at all [5]. Triodos Bank’s 180bn euro figure for this year is a forecast, not a measurement, and should be read as one [4].

The two halves also feed each other. Britain’s July inflation rose to 2.9%, driven by a 13% jump in the energy cap worth 221 pounds on a typical bill [10][16]. Cornwall Insight notes the European heatwave is itself lifting gas demand, because power stations are running to drive air conditioning [16]. The heat nobody stopped is now inside the bill people are arguing about.

That argument is where the attention sits. Britain’s opposition says scrapping climate rules would save over 320bn pounds. Carbon Brief’s factcheck finds the same plan yields 524m more tonnes of carbon dioxide by 2050, and less electrification rather than more [11]. A survey of 100 sitting MPs, meanwhile, found they underestimate public support for climate policies by 11 percentage points [12].

02 · Lesson · why it matters

Why your share of the cause is not your share of the damage

You can only cut your own slice of a shared cause, but the consequence arrives whole.

How it works

A harm has many causes, spread across the world
You can only cut your own slice of the cause
But the consequence arrives whole, at your address
So cutting protects you in proportion to your slice
Coping works whatever anyone else does
The smaller the slice, the more of your safety is coping

The twist

You can only cut your own share of a shared cause, but you get the whole of the consequence - so the smaller your share, the less your own cutting can protect you.

Where you've seen this

A flooded street

one household cannot change the river's catchment, but it can raise the sockets

A small firm paid late

it cannot change its industry's payment habits, so it holds cash instead

A hospital ward

it cannot fix how the world prescribes antibiotics, so it screens and isolates

A town losing its industry

it cannot set trade policy, so it retrains and keeps the college open

The catch

Coping has a ceiling - it costs more as the hazard grows, and if everyone reasons this way, nobody cuts at all.

Full lesson

The canal cannot make it rain

Panama did not warm the Pacific. It burns very little of the world’s fuel. But El Nino weakens the winds that carry rain to the isthmus. The two lakes that fill the canal’s locks fall, and every ship that crosses spends water Panama no longer has.

So the canal authority does the only thing available to it. It lets fewer ships through - 34 a day from early September, 32 a fortnight later, and 22 a day the last time this happened.

That is the whole shape of the thing, in one country. The cause is everybody’s. The consequence is Panama’s, entire.

Two jobs that stopped being alternatives

There are two ways to deal with a harm like this. You can work on the cause, or you can work on the consequence.

Working on the cause has a hard ceiling built into it: you can only change your own contribution. Europe accounts for about 6% of the world’s greenhouse gases. If Europe went to zero tomorrow, roughly 94% of the pressure on its own summers would still be there, decided by other people. Panama’s slice is far smaller than that. Assam’s is smaller still.

Working on the consequence has no such ceiling. A raised road, a herbal ley that holds water in the soil, a cooled building, a wider reservoir - these work regardless of what anyone else does. They do not need a treaty. They do not need anyone else to go first.

Which is why the arithmetic tilts as your slice shrinks. The smaller your share of the cause, the less of your own safety cutting can buy you. The rest has to come from coping.

And yet the money goes the other way

Europe plans somewhere near 69 billion euros a year on adapting to heat, against clean-energy investment of nearly 700 billion a year in the 2030s. Ten to one, against the direction the arithmetic points.

Where the argument sits explains much of it. Britain’s opposition has just published a report claiming that scrapping climate rules would save over 320 billion pounds. Carbon Brief’s factcheck says the same plan would put out 524 million more tonnes of carbon dioxide. Both sides of that fight are arguing about the cutting. The number nobody is fighting over is how much shade a British city has.

The cutting side has a target, a treaty, a unit of account, a scoreboard. Tonnes are counted, reported, compared, argued about. The coping side has almost none of that. Researchers published a shared list this week tying 35 climate hazards to eight big risks. Until now the field had no common language for what it was measuring. A thing with no scoreboard does not get a budget.

The half nobody bills for

You can watch this in the insurance numbers. Moody’s puts last summer’s European heat at about 43 billion euros of lost output - and about 500 million euros of insurance paid.

Heat is strange that way. It breaks almost nothing. A cafe in Padua with an empty terrace has no damaged property to claim on; it just has a month where the money did not come in. There is no wreckage to photograph, so there is no claim, so there is no number, so there is no pressure to prepare.

Where you are standing in this

You are inside both halves, and you probably only see one.

Your electricity bill funds the cutting - in Britain a 13% cap rise this July, 221 pounds on a typical year. That number arrives in an envelope with your name on it, so you notice it. The coping half arrives as things that quietly are not there: the reservoir nobody built, the tree nobody planted on your street, the cooling your school does not have. Nobody bills you for an absence.

And the arrangement decides who carries it. In the Colorado deal, three downstream states take a 21% cut and the four upstream states take none by order. In Assam, more than a hundred people drowned in the state’s worst floods in sixty years. The spending there goes to rescue rather than to lowering the risk. That is not a failure of care. It is what is easy to fund once the water is already rising.

None of us can see our own share from where we stand. Panama did not cause El Nino, and Panama is still the one holding the queue.

03 · Lab · your turn

Cut or cope

Split a fixed budget between cutting your own emissions and coping with the heat, and watch how the best split moves with your share of the cause.

04 · Hope · carry this

The half of this that needs nobody's permission is the half that works fastest. A farm in Essex kept its grass green through a rainless summer, because someone thought about the soil years before the drought came.
