Digital twins in cockpits will help planes look after themselves

Digital twins are virtual representations of a component, a device or even an entire production line in a factory. Fed with data from sensors installed on its physical opposite number, the digital version can be used to plan maintenance, spot or predict any emerging problems and simulate the effect of upgrades and design changes. This would involve creating a digital twin of an entire plane by merging its various monitoring systems and interpreting the result using artificial intelligence.

How much does eating meat affect nations’ greenhouse gas emissions?

Food we eat accounts for one-third of global greenhouse gas emissions caused by human activities. Food supply chain emissions bring food-related emissions up from 20 percent to 33 percent. To slow climate change, the foods we eat deserve major attention, says Amos Tai, an environmental scientist. Food system emissions are broken down into four broad categories: land, energy, industry, waste and waste from unused food. Land is the biggest culprit in food system emissions, accounting for about 70 percent of the global total.

These are the most magnificent green buildings around the world

Speaking of land emissions, the UN predicts that 68 per cent of the world’s population will live in cities by 2050. Urban gardens and vertical farms are starting to pop up all over the world. Sustainable architecture is all about minimising the environmental impact of the structure, through energy efficiency and eco-friendly materials.

Vacuuming carbon from the air could help stop climate change. Not everyone agrees

Some of the biggest companies in the world are spending $1 billion on a new climate change strategy. It involves pulling carbon dioxide emissions right out of the air. Scientists say using it will be “unavoidable” if countries are going to meet their pledges. Greenhouse gas emissions need to drop 43% by 2030 and then fall to net zero by mid-century. Some solutions to cut emissions are already widespread and cost-effective. By the midcentury, the overall level of greenhouse gases in the atmosphere needs to stop rising.

Planting trees rather than bioenergy crops sucks more CO2 from the air

In the US, nearly twice as much carbon dioxide could be removed from the atmosphere by 2100 through planting forests than through growing bioenergy crops. Growing forests would lead to fewer water shortages and less water pollution, according to a modelling study in the journal Climatology.
