For a snapshot of Earth’s future, look to Venus.
Assuming life on Earth survives humanity’s fossil-fuel binge (it probably will), it will nonetheless inevitably be doomed by climate change of even-more-epic proportions. We’re talking about stellar warming.
Life is only possible on planets that orbit stars inside a particular band of space that enables things like moderate temps, liquid water, etc. Earth currently sits within our sun’s habitable zone, but that won’t be the case forever: As the sun ages and grows hotter, its so-called habitable zone creeps outward by about a yard every year.
Research published in the journal Astrobiology projects that Earth could slip out of the sun’s habitable zone somewhere between 2 and 3 billion years from now. Earth’s water will evaporate, leaving The Rock Formerly Known As The Blue Planet as sterile as Venus. Nature explains:
The luminosity of a typical star increases as its composition and chemical reactions evolve over billions of years, pushing the habitable zone outward. Researchers reported in March that Earth is closer to the inner edge of the Sun’s habitable zone than previously thought.
The inner edge of the Sun’s habitable zone is moving outwards at a rate of about 1 metre per year. The latest model predicts a total habitable zone lifetime for Earth of 6.3 billion–7.8 billion years, suggesting that life on the planet is already about 70% of the way through its run.
All we need to do now is tackle the global warming problem and make sure that life stays habitable for humans for as many of those billions of years as possible. And if we manage to do that? One of the scientists involved with the study thinks we should book it for the next planet over.
“If we are still around, and the optimist in me likes to think we would be, I hope we’d be away from the Earth, perhaps on Mars, or spread out in a huge galactic family across the Milky Way,” University of East Anglia’s Andrew Rushby told The Guardian.
Step one: Solve anthropogenic global warming. Step two: Move to Mars. Seems easy enough.

Gypsy moth larva, a pest in America’s forests, is even more pesky these days.
Pests are packing their metaphorical bags and heading for fresh starts nearer the North Pole as the climate warms around them.
Beetles, moths, fungi, and other pests that afflict forests and crops in the Northern Hemisphere are expanding their ranges northward by an average of 24 feet every day.
That’s according to British scientists who studied the records of infestations of 470 pests around the world since 1960 and measured the rate at which their ranges appeared to be shifting. They say their findings reveal a potential threat to food security posed by global warming.
The northerly march “is more rapid than that reported for many wild species,” the scientists wrote in a paper published Sunday in the journal Nature Climate Change. And it’s “nearly identical” to what would be expected from rising temperatures.
The findings show that termite pests are moving poleward the most quickly, at an average rate of 177 feet daily. Butterfly, moth, thrip, and beetle pests are moving north at an average of about 70 feet per day.
“There has been much research over the past couple of decades showing that wild populations of plants and animals have been moving poleward in response to warming,” study lead author and University of Exeter biosciences research fellow Dan Bebber told Grist. “Our paper shows that this is happening in pests as well.”
The northward movement of pests coincides with new farming practices that are pushing farms closer to the poles. But Bebber is convinced that the pests are moving in response to the changing climate. “Changes in farming practices and land use would probably lead to simple range expansion of pests, rather than a directional shift as we have demonstrated,” he said.

Crop-munching pests are traveling north as the climate changes

Open your eyes: The clouds are disappearing, too.
Next time you’re at the beach take a deep, long sniff: That special coastal scent might not last forever. While you’re at it, put on some extra sunscreen: As that smell dwindles, cloud cover could, too.
The unique oceanside smell that flows over your olfactory organs is loaded with sulfur — dimethylsulfide, to be exact, or DMS. It’s produced when phytoplankton decompose. And it’s a fragrant compound that’s as special as it smells: In the atmosphere it reacts to produce sulfuric acid, which aids in the formation of clouds.
But it’s a smell that’s endangered by climate change. Experiments have linked the rising acidity of the world’s oceans to falling levels of DMS. A paper published online Sunday in the journal Nature Climate Change warns that ocean acidification could reduce DMS emissions by about one-sixth in 2100 compared with pre-industrial levels.
Clouds do more for us than just dispense quenching rain and snow: They also reflect light and heat away from the earth, helping to keep temperatures down.
Scientists at the Max Planck Institute for Meteorology found that the knock-on effects of rising ocean acidity threaten to rob the world of so much of its cloud cover that global temperatures could noticeably rise.
“Marine DMS emissions are the largest natural source of atmospheric sulphur and changes in their strength have the potential to alter the Earth’s radiation budget,” the scientists wrote. From an explainer article in Nature:
On a global scale, a fall in DMS emissions due to acidification could have a major effect on climate, creating a positive-feedback loop and enhancing warming. …
In a ‘moderate’ scenario described by the Intergovernmental Panel on Climate Change, which assumes no reductions in emissions of heat-trapping gases, global average temperatures will increase by 2.1 to 4.4 °C by the year 2100.
The model [used for the new research] projected that the effects of acidification on DMS could cause enough additional warming for a 0.23 to 0.48 °C increase if atmospheric CO2 concentrations double. The moderate scenario projects CO2 doubling long before 2100.
Diminished cloud cover and rising temperatures are bad enough, but the real horror might be raising kids in a world where the only place you can smell the ocean is Bath & Bodyworks.
