If Each of Us Planted a Tree, Would It Slow Global Warming?

If Each of Us Planted a Tree, Would It Slow Global Warming?

So to start, let’s figure out how much carbon a single tree can hold.To convert this to mass, I’m going to assume a wood density (ρ) of 500 kilograms per cubic meter, which is half the density of water.The mass of my generic tree would then be:Illustration: Rhett Allain

What to Look for in CNN's 'Climate Crisis' Town Hall Tonight

So as you watch all seven hours of the Town Hall tonight, as I’m sure you will, look for the ways candidates talk about the policy course they plan to follow, not just because it’s important for, like, saving the planet and stuff, but also because it’ll provide a clue to what election strategy they hope to pursue.

See How LA Belches Emissions, Block by Block

See How LA Belches Emissions, Block by Block

So instead of relying on satellites alone, a group of researchers combed through data from a dizzying number of publicly available sources, looking at everything from traffic patterns to utilities data to air pollution reporting, to quantify the emissions from not just every road but every building in the nearly 5,000 square miles of the Los Angeles megacity.

Why a Promising, Potent Cancer Therapy Isn't Used in the US

Why a Promising, Potent Cancer Therapy Isn't Used in the US

The nuanced answer is that no one knows for sure, because neither carbon ion nor proton therapy has “gold standard” evidence from randomized Phase III clinical trials showing patients live longer with the treatment than with standard radiation.

The Horrifying Science of the Deforestation Fueling Amazon Fires

The Horrifying Science of the Deforestation Fueling Amazon Fires

Humans carve out farmlands, sometimes leaving a neat edge where the forest meets the fields, or even creating islands of forest surrounded by crops or grazing fields for cattle.

Humans, More Than Drought, Are Fueling the Amazon's Flames

Humans, More Than Drought, Are Fueling the Amazon's Flames

The fiery, anti-environment populist has encouraged settlements in the Amazon region, sacked the head of the government agency that monitors deforestation from space, and just this week blamed NGOs for setting the fires to make him look bad.On Tuesday, a satellite took this image of forest fires burning across three Brazilian states.

Melting Glaciers Are Helping Capture Carbon

Melting Glaciers Are Helping Capture Carbon

On average during the 2015 melting season, per square meter (to be clear, not in total ) these glacial rivers consumed twice as much CO2 as the Amazon rainforest.

New IPCC Report Shows How Our Abuse of Land Drives Climate Change

New IPCC Report Shows How Our Abuse of Land Drives Climate Change

This new report takes steps to quantify how our abuse of the land—deforestation, industrial agriculture, draining of carbon-capturing peatlands—is driving climate change, and in turn how that climate change is exacerbating the degradation of land the world over.

Sorry, But We Can’t Just Hack Our Way Out of Climate Doom

Sorry, But We Can’t Just Hack Our Way Out of Climate Doom

“Suddenly stopping solar geoengineering could cause the climate to change very rapidly, allowing ecosystems and economies less time to adapt to new conditions,” says Proctor.

We’re Eating This Planet to Death

“We can reduce our demand, or we can increase the amount of land we grow stuff on and the number of animals that produce food,” says Van Eenennaam.

Icy Waterfalls Are Roaring as a Heat Wave Sizzles Greenland

Icy Waterfalls Are Roaring as a Heat Wave Sizzles Greenland

As a glaciologist who studies the plumbing system of Greenland’s ice sheet, Gulley is one of the foremost explorers of these melt caves, called moulins. The study also projected that Greenland’s ice sheet will completely melt in the next 1,000 years unless society drastically reduces carbon emissions and bends the climate curve.

The Bizarre, Peaty Science of Arctic Wildfires

The Bizarre, Peaty Science of Arctic Wildfires

That, though, would require forest management across swaths of the Arctic, a kind of management we in the US can’t even do right on a small scale .What we’re looking at, then, is yet another complicating factor in the massive complexity that is climate change: When peat burns, it emits lots of CO2, and when peatlands aren’t healthy, they don’t capture any.

Climate Change Is Very Real. But So Much of It Is Uncertain

Climate Change Is Very Real. But So Much of It Is Uncertain

But today in the journal Nature , researchers are proposing a new framework that aims to bring clarity to this kind of work, first by reconciling differences in carbon budgets and second by reducing uncertainty going forward.

Trees Emit a Surprisingly Large Amount of Methane

Trees Emit a Surprisingly Large Amount of Methane

But in a world where corporations plant trees to offset their carbon emissions, we badly need to know if their numbers add up, or if they are undermined by the complex chemistry of trees and methane.“In the seasonally flooded part of the Amazon, the trees become a massive chimney for pumping out methane,” says one researcher.

What to Do About CO2? Try Stuffing It Into the Gulf of Mexico

What to Do About CO2? Try Stuffing It Into the Gulf of Mexico

“These offshore CO2 storage facilities are probably a reasonable idea because the benefits of storing 1 million tons per year of carbon are larger than the effects of the leakage that may occur,” says Klaus Wallmann, professor of marine biogeochemistry at the GEOMAR Center for Ocean Research in Kiel, Germany, and an author of the report.

Climate Adaptation Isn’t Surrender. It’s Survival

For one thing, science fiction fans are not new to post-apocalyptic scenarios, whether it’s robot uprisings, mysterious unnamed disasters that leave the planet uninhabitable, total Wall-E style environmental collapse, or actual climate-change-inspired disaster, as in Kim Stanley Robinson’s New York 2140 , which imagines a mostly drowned Earth after 100 feet of sea level rise over just a few decades.

Atmospheric Methane Levels Are Going Up—And No One Knows Why

Atmospheric Methane Levels Are Going Up—And No One Knows Why

“We need to have process representation to understand these mechanisms,” says Eric Kort, an atmospheric scientist at the University of Michigan, “so we can say, for example, with certain changes to temperature and the hydrological cycle, we’d expect methane emissions to increase by X amount.” Without that understanding, Kort suggests, we’re unable to answer some important questions about what looms ahead.

What if Air Conditioners Could Help Save the Planet Instead of Destroying It?

What if Air Conditioners Could Help Save the Planet Instead of Destroying It?

“Carbon-neutral hydrocarbon fuels from electricity can help solve two of our biggest energy challenges: managing intermittent renewables and decarbonizing the hard-to-electrify parts of transportation and industry,” says David Keith, acting chief scientist of Carbon Engineering, which is developing much larger stand-alone devices for sucking CO2 out of the air and storing it, known as carbon capture and storage, or CCS.
