Paris and climate change

September 8, 2025 By EarthWise Leave a Comment

Officials in Paris are taking steps to prepare for a warmer future

Paris is associated with climate change by virtue of the 2015 international agreement seeking to limit the amount of warming taking place on the planet.  But Paris is well aware that the world is not making much progress in meeting the goals of that agreement and the French capital is already suffering from the impact of the warming climate.

France has had multiple heat waves this summer that have seen multiple record high temperatures across the country.  Eight of the 10 hottest summers recorded in Paris have occurred since 2015.

Paris officials have performed heat crisis simulations to learn what the effects of extreme heat situations would be.  One simulation looked at the impact of temperatures reaching 122 degrees.  The consequences to many of the city’s functions and systems would be dire.  This might seem outlandish, but in 2019, temperatures in Paris reached 109 degrees, and climate change is warming Europe at more than twice the global average.  With its zinc roofs, squares paved with stone, and highest population density in Europe, Paris is especially ill-suited to hot weather.

Paris is taking steps to prepare for a warmer future.  It is pulling up asphalt parking places and road centers to plant trees, 15,000 last winter alone.  It is putting up more shade structures and water misters.  Paris is insulating older buildings – 7,000 a year now and a goal to reach 40,000 a year by 2030.  Paris is registering isolated older or disabled people, so that they can be checked on during heat waves.

It is a race against time.  Paris is trying to prepare for the changes to come.

Turning Carbon Into Stone | Earth Wise

Start-up plans to turn carbon into stone

A start-up company in Oman called 44.01 was recently awarded a $1.2 million Earthshot Prize by Prince William of the U.K.  The company, whose name corresponds to the molecular weight of carbon dioxide, is working on speeding up natural chemical reactions that take carbon from the air and lock it into solid mineral form.

The company’s location in Oman is no random occurrence.  The mountains of northern Oman and along the coast of the United Arab Emirates are the site of a huge block of oceanic crust and upper mantle that was thrust upward some 96 million years ago.  The tilted mass of rock is over 200 miles long and is the largest surface exposure of the Earth’s mantle in the world.

This type of rock, called peridotite, is rich in olivine and pyroxene, which react with water and carbon dioxide to form calcium-based minerals like serpentine and calcite that permanently lock in carbon. Other kinds of rock also are capable of carbon-storing mineralization, but this mantle rock is the most effective for the purpose. It only exists at the Earth’s surface in a few places, including Papua New Guinea and some spots in California and Oregon.

The 44.1 company is planning to use solar-powered direct air capture devices to remove CO2 from the air, use it to produce carbonated water, and inject the water into the reactive rocks.  The company will operate a couple of pilot systems during 2023.  Ultimately, the company believes it can scale up the process to be able to permanently sequester as much as a billion tons of CO2 a year by the year 2040 without needing to inject the gas into deep caverns or find other places to store it.

Oman’s Rocks

There is growing interest in the idea of capturing and storing carbon dioxide.  Reducing the amount of it we are putting into the atmosphere is essential for limiting the effects of climate change, but even eliminating emissions entirely is not enough because the CO2 already there stays in the atmosphere for decades or more.

Turning Carbon Dioxide Into Rock

There is a lot of interest in figuring out a way to store carbon dioxide produced from industrial processes and energy plants or even sucking it out of the atmosphere and then storing it.   The problem is where exactly to put the stuff and how to make sure that it stays there.

Anyone who has walked the streets of New York City or Washington, D.C. on a stifling summer day can attest to the fact that cities feel hotter.  It’s not a matter of perception.
