The key thing here is that the less overshoot the better, and the amount of overshoot we can afford is small.

“All models are wrong” could just mean that all models include some idealizations or abstractions. And just as Box says, models that employ such idealizations and abstractions can still be advantageous. Indeed, a highly idealized model that leaves out tons of real-world processes will be much easier to understand than a model that tries to capture, say, every gust of wind and every drop of rain.

• An expedition by more than 50 researchers from seven countries has documented the gradual degradation of Antarctica: microplastics in the water, melting ice, and declining salinity in the Southern Ocean.
• The team found microplastics in both glacial ice and seawater.
• They also noted that atmospheric “rivers” are sending ash-laden air from Amazon forest fires to Antarctica, hastening the melting of snow and ice there.
• The accelerated melting means more freshwater is rushing into the Southern Ocean, reducing the salinity level and affecting the phytoplankton that form the basis of the marine food chain.

• Sri Lanka’s isolation during past glacial cycles resulted in the evolution of unique species, but ongoing human-induced climate change now poses a major threat to their survival.
• Using species distribution models, researchers have discovered that montane amphibians and reptiles that are particularly restricted to narrow ecological niches with limited mobility are particularly vulnerable to rising temperatures.
• Species with direct development, like many Pseudophilautus frogs, which bypass the tadpole stage, are especially sensitive to microclimate changes.
• Of the 34 amphibian species confirmed extinct worldwide, 21 were endemic to Sri Lanka, underscoring the island’s fragility and the urgent need for targeted conservation efforts.

• Más de 50 investigadores de siete países dan cuenta de la paulatina degradación de la Antártida: microplásticos en el agua, derretimiento del hielo y pérdida de salinidad del océano austral.
• Dada la conexión que existe entre la Antártida y la Amazonía, los científicos no descartan que en el hielo existan rastros de los incendios forestales.
• La situación es preocupante puesto que la Antártida, aunque remota, tiene una dinámica de conexión constante con el resto del planeta.
• Los cambios que ocurren en ella influyen en la regulación del clima global.

Among other concerns, the US military parade will produce as much pollution as created to heat 300 homes for a year

Donald Trump’s military parade this weekend will bring thousands of troops out to march, while dozens of tanks and armored personnel carriers roll down the streets and fighter jets hum overhead.

The event has prompted concern about rising autocracy in the US. It will also produce more than 2m kilograms of planet-heating pollution – equivalent to the amount created by producing of 67m plastic bags or by the energy used to power about 300 homes in one year, according to a review by the progressive thinktank Institute for Policy Studies and the Guardian.

The military parade is meant to celebrate the US army’s 250th anniversary on 14 June – which will also coincide with the president’s 79th birthday. It will feature 150 military vehicles including 60-ton tanks and armored fighting vehicles, and more than 50 helicopters and aircraft such as a Mustang fighter aircraft and a B-25 Mitchell bomber, which were both used widely during the second world war. These vehicles burn dozens or even hundreds of gallons of fuel per hour.
