Better book a ticket to Mars for your grandkids before the economy collapses.

Mars' environment is worse that inhospitable, it's deadly. Getting there is horrendously expensive and requires a huge amount of infrastructure and technical support. Surviving there would wholly rely on a vast amount of material support from Earth. The provision of material support for Mars colonists would depend on a functioning economy on Earth. There's no economy on a dead planet, and a lifeboat only defers the inevitable when there's nowhere left to sail too and no-one left to effect a rescue.

"But no!" you say. Like the famed 2nd coming of Jesus, the apocalypse is inevitable and inescapable, and we will all be washed away for our ecological sins, and Mars, like Heaven itself, will be the only sanctuary for the righteous and the chosen - if they just believe hard enough. If you believe it you can buy your grandchildren their tickets today.

In 2008, Krugman was the winner of the Nobel Memorial Prize in Economic Sciences for his contributions to New Trade Theory and New Economic Geography refuting rational considerations and showing there's no logic to trade routes - Would America even have got going, with logical considerations at the time?

A new way to clean up the steel industry
Carbon dioxide emissions could be cut by more than 90%

Making steel is a dirty business. For every tonne of it some 1.8 tonnes of carbon dioxide (CO2) are emitted into the atmosphere. As a result :o , steelmaking accounts for 7-9% of the world’s anthropogenic greenhouse-gas emissions.

The UK would have to devote half its farmland or more than double its total renewable electricity supply to make enough aviation fuel to meet its ambitions for “jet zero”, or net zero flying, scientists have said.

A report published on Tuesday by the Royal Society argues there is no single, clear, sustainable alternative to jet fuel that could support the current level of flying.

The scientists say that while the government and aviation industry have set a target of 2050 to balance out emissions, huge challenges remain around the availability, costs and impacts of alternative fuels, as well as the need for new types of planes and airport infrastructure around the world to allow the most probable long-term solutions....

EV and hydrogen planes will take a good chunk of the ICE flights especially for Euro hops.
Trans oceanic will be a challenge. Using cropland to "grow" energy for transport is a non-starter.
Seaweed might help in that regard.

Does that mean we actually can find a use for those huge algal blooms that have been polluting our coasts?

Algae for fuel is best done in a bio-reactor not wild harvested but feeding the river water into the algae ponds works. This was 10 years ago.

The EU-backed All-gas project, in southern Spain, claimed to be the largest in the world to convert algae into energy using wastewater, has successfully grown its first crop of algae biomass at its site in Chiclana...
