All Aboard: how you can be a part of our research blog

Hi there! I’m Rose, a science journalist and producer. I live in Brooklyn now, where I write, produce and generally try to explain science-y things. But in a few weeks, I’ll be writing to you from somewhere far, far away from Brooklyn: the North Atlantic Ocean. I’m heading out to sea with a research group [...]

The Catlin Arctic Survey: A melting ocean

There have been many media headlines recently concerning the melting of the sea ice in the Arctic Ocean, often focused on the opening of the North West Passage and further commercial opportunities in this region. Current predictions are that there will be no summer time sea ice coverage by 2050. This increased flux of fresh [...]

The Catlin Arctic Survey: Thermohaline circulation

If you look at a map of the world and draw a line through London, a latitude of about 50 degrees North and follow this line across the world, you’ll see that it passes through southern Siberia and skims the southern shores of Hudson Bay in Canada. The week before I came out to the [...]

The Catlin Arctic Survey: The science

I do not consider myself to be an explorer and I have never had the desire to walk to the North Pole. I always compete with the cat to be in the warmest spot in the house. I take a hot water bottle to bed in the summer and I do not like to be [...]

Can we capture all of the world’s carbon emissions?

In 2011, the world will emit more than 35 billion tons of carbon dioxide. Every day of the year, almost a hundred million tons will be released into the atmosphere. Every second more than a thousand tons – two million pounds – of carbon dioxide is emitted from power plants, cars, trucks, ships, planes, factories, [...]

Climate research in the geologic past

"Fire and Ice" Some say the world will end in fire, Some say in ice. From what I’ve tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To say that for destruction ice Is also great And would suffice. Robert [...]

How to stop a hurricane (good luck, by the way)

As another hurricane season passes, I’m disappointed I didn’t hear Bill Gates resound with last year’s grand (yet perhaps logistically impossible) idea to dump tons of cold water in the path of moving twisters like Karl, Danielle, Lisa, and Tomas. Maybe Steve Jobs is plotting a more hip idea for 2011… Despite a tech mogul’s [...]

Now in 3-D: The shape of krill and fish schools

Watching videos of fish feeding frenzies is a very emotional experience for me. You know the videos I’m talking about (personal favorites here, 0:55 in, and here). They feature a swirling, glittering mass of fish that seems to dance and flit as a single entity while being torn apart by three or four types of [...]

Solstice, Periapsis, and the Hades Orbit

The Sun rising above the Arctic plain (H. D. Nygren, NOAA Corps.)

As our spinning globe of rock and metal tracks its steady path around the Sun, we find ourselves crossing once again through the winter solstice, the point at which Earth’s northern pole is pointed as far from our fierce stellar parent as it can be (this year at a coordinated universal time of 5.30 am [...]

Climate Change Future Suggested by Looking Back 4 Million Years [Video]

The last time the Earth enjoyed greenhouse gas levels like those of today was roughly 4 million years ago, during an era known as the Pliocene. The extra heat of average temperatures as much as 4 degrees Celsius warmer turned the tropical oceans into a nice warm pool of bathwater, as noted by new research [...]

Smog Blog: World-Class Pollution Brings Tehran to a Halt

Tehran, smog, Tehran smog

During the first weeks of 2013, Tehran was often blanketed in a stagnant, brown layer of smog so thick and obtrusive that it was difficult to make out the conspicuous mountain ranges that encircle the city. After trying to regulate the number of cars on the streets, a measure that failed to reduce the noxious [...]

Carbon Onset: CO2 Debt of Climate Conferences Grows and Grows and Grows

Solar panel at climate talks in Durban, South Africa

DURBAN, South Africa—When roughly 25,000 people descend on a city to talk climate change, you can expect at least two things: mountains of waste and copious emissions of the greenhouse gases that they’ve come to talk about so seriously. To offset the hundreds of thousands of tons of these lightweight gases emitted in the pursuit [...]

Damage from Extreme Weather Increasing

Hurricane Irene is part of a worsening trend. Weather disasters have grown more frequent and more costly over the past 30 years in the U.S., according to data that was released today by the National Oceanic and Atmospheric Administration (NOAA). On Thursday afternoon, NOAA posted a map of the 99 weather disasters that caused at [...]

What does a blizzard on the U.S. East Coast mean for global warming?

brooklyn-snowstorm-2010

Short answer? Not much. In fact, while no single storm is anything more than weather, stronger winter storms are exactly what climate scientists expect from a warming climate. How can that be? Simple. Warmer air allows for more water vapor, the key constituent of snow (which accords with the folk wisdom from my home state, [...]

New research confirms global surface winds are slowing, blames land use changes

Are surface winds around the world really slowing down? That’s the suggestion of a new study in Nature Geoscience. The authors built on previous studies indicating such a trend by analyzing surface wind data from 822 wind stations in Europe, Asia and North America. The study concludes that the widespread "atmospheric stilling" has more to [...]

Cloud-talk decoded: Physics and lasers read honeycomb cloud pattern

honeycomb cloud patterns determined by rain

A thin, patchy cloud cover with clusters that seem to continuously form, dissipate and reemerge might not be just flowing at random. When these cloud fields appear over the ocean at least, their cycles and patterns are in fact quite regular, and new research explains how precipitation keeps an accumulation of these clouds knit closely [...]

Is the cure (geoengineering) worse than the disease (global warming)?

mount-pinatubo

If there’s one thing more potentially contentious than the international politics of global warming (which the world has spent at least the past 20-plus years dithering about), it’s the politics of the most radical suggestion to solve it: geoengineering. After all, he who controls Earth’s thermostat may well control Earth. And what’s good for one [...]

How close are we to catastrophic climate change?

earth

As you may have noticed, scientists remain convinced that humans are altering the global climate with an excess of greenhouse gas emissions—soot, methane and the ever-present carbon dioxide we pump out from our lungs and coal-burning power plants. The question is: how bad is said climate change going to get? After all, concentrations in the [...]

These Stairs Aren’t Climbing — They’re Flat!

There’s been quite a bit of reaction to the article published by the Economist, dated March 30, suggesting that there may be evidence that climate change has been overestimated. The data that concern those cheering the Economist writers is an apparent lack of warming since 1998 or so. Here’s a video package the Economist put [...]

Oil Might Be a Renewable Resource, and Other Things You Did Not Know

Or, “Thank God there’s a North Carolina.” Yep. We have a new governor, which means new secretaries of this and that. Meet John Skvarla, new secretary of the Department of Environment and Natural Resources (DENR, to tarheels). To cut to the chase, here’s your takeaway idea: maybe oil is a renewable resource.
