Brexit destroys the British convention of former leaders treading carefully around the incumbent

Former prime ministers Gordon Brown, Tony Blair, David Cameron and John Major, who attended a memorial service on Sept. 10, have all criticized Boris Johnson’s moves on Brexit.

LONDON—Brexit has dented another distinguished British convention: Former prime ministers no longer refrain from criticizing successors from their own parties.

On another bracing day in the drama surrounding the U.K.’s break from the European Union, two former Conservative British prime ministers threw barbs at Prime Minister Boris Johnson over the fraught issue. Den Rest des Beitrags lesen »

Humanity will find ways to adapt to climate change

Climate issue: That is no reason to give up on stopping it

After destructive storms like Hurricane Dorian, those affected have decisions to make. Should they invest in cellar pumps and better drainage? Should they rebuild with more robust design and materials? Should they move? These judgments are informed by a harsh reality: the weather will get worse. Seas will be higher, rain more diluvial and storms fiercer. People with means will naturally adjust—as they should. Adaptation is essential to reduce the human and economic costs of climate change. But spending on adaptation may further complicate already-confounding politics.

Efforts to slow global warming must overcome devilish political obstacles. The benefits to reduced warming accrue over decades and centuries, whereas the cost of cutting emissions must be paid upfront by taxpayers who cannot expect to see much return in their lifetimes. And mitigation (as efforts to curb emissions are called) is subject to a vicious collective-action problem. Climate harms are determined much more by what everyone else does than by what you do. Each actor has an incentive to free-ride on the sacrifices of others. Cutting emissions requires every large country saddling voters with expense and inconvenience that will mostly help people elsewhere, or not yet born. Den Rest des Beitrags lesen »

Predicting the climatic future is riddled with uncertainty

But researchers are doing the best they can

The world’s climate scientists are charged with a difficult task: to create a crystal ball with which to skry a future that promises to be hotter than today. But exactly how much hotter depends on innumerable factors, both natural and human. Creating the crystal ball is thus a two-stage process. First, you have to build a simulacrum of how Earth’s climate works. Then, you try to perturb this simulacrum with plausible future human actions, to see what picture appears.

Modern magic being what it is, the crystal balls are actually supercomputers running programs with 1m or more lines of code. These programs are models that divide the planet’s atmosphere, ocean and land surface into grids of cells—many millions of them. Land cells are flat. Atmosphere and ocean cells are three-dimensional and are stacked in columns to account for the effects of altitude and depth. A model calculates what is going on, physically and chemically, inside each cell, and how this will affect that cell’s neighbours, both sideways and, if appropriate, above and below. Then it does it again. And again. And again. Den Rest des Beitrags lesen »
