Humans Bring On Many Changes, Most Are Far From Painless

What happens in Vegas apparently spreads from Vegas....

From atmospheric changes, to timelapse imagery from Google Earth…our planetary presence is hard to miss. This past week has seen the concentration of carbon dioxide (CO2) in Earth’s atmosphere reach a level of 400 parts-per-million, a value the planet hasn’t seen since several million years ago. To put this into some kind of context let’s [...]

Clean Coal Era Begins

boundary-dam-power-plant

On October 2, the Boundary Dam power plant in Saskatchewan became the first full-sized coal-fired boiler to capture the copious carbon dioxide that had previously billowed from its smokestack, preventing the greenhouse gas from entering the atmosphere. On the resulting invisible stream of hot smoke ride the hopes of combating climate change while still burning [...]

Americans Who Mistrust Climate Scientists Take Cues from Global Temperatures

Screen shot 2014-07-29 at 5.02.50 PM

The White House obviously accepts the science behind human-caused climate change, as was made clear again this week by its announcement of plans to cut carbon emissions from U.S. power plants 30 percent from 2005 levels by the year 2030. Some Americans remain skeptical—but they’re in the minority. As The New York Times reports, most [...]

Keystone Pipeline Will Impact Climate Change, State Department Reports

oil-sands-refinery

How much can one oil pipeline affect global climate change? That’s one of the fundamental questions probed by a new, final environmental impact assessment released January 31 by the U.S. State Department. At issue is the Keystone XL pipeline, which would carry 730,000 barrels a day of oil from western Canada, mostly from Alberta’s tar [...]

Climate change is real, it’s here and it will be affecting the planet for a long, long time. That’s the lesson of the latest iteration of the Intergovernmental Panel on Climate Change‘s state of climate science report, released in its entirety on January 30.

What You Need to Know about the Forthcoming Climate Change Report

Talk about management by committee: one group of more than 800 scientist authors to cope with more than 9,000 scientific publications on climate change and more than 20,000 comments from “expert reviewers” (plus another 30,000 or so from various other interested parties.) Now the Intergovernmental Panel on Climate Change is into four days of wrangling [...]

The Answer to Coal Climate Pollution Is Natural Gas and Carbon Capture, EPA Says

mccarthy-sworn-in

The Environmental Protection Agency has new rules for how much carbon dioxide power plants can spew. Designed to ensure that no new plants built in the U.S. can be highly polluting, the regulations would prohibit the dirtiest coal-fired power plants without additional technology to capture and store CO2. The trouble is: hardly any such coal-fired [...]

The Climate May Be Changing, but the IPCC Remains the Same

ipcc-first-session-in-1988

By 2021, climate scientists should be 99 percent certain that climate change is our fault—up from 95 percent certain presently and a mere 90 percent certain all the way back in 2007. This conclusion of the leaked draft of the forthcoming assessment of the Intergovernmental Panel on Climate Change (IPCC) begs the question: Is any of [...]

On a sweltering day in Washington, D.C., President Barack Obama sweated as he laid out his new plan to combat climate change. In addition to the mandatory cuts in CO2 pollution from coal-fired power plants and the efforts to protect the country from the ravages of climate change highlighted by my colleague Mark Fischetti, Obama [...]

You may recently have read about climate change and North Carolina for all the wrong reasons, entailing laws designed to forbid the mentioning of the term “climate change” as well as outright banning measurements of sea-level rise. At the heart of this drama, is elevation mapping technology applied to climate change to better understand future [...]

Fuel/Cost Savings of Improving Fuel Economy from 12->15 mpg = 30->60 mpg

Fuel economy is not as straight-forward as you might think. Image courtesy: fragallo

Consumer tip-of-the-day: increasing efficiency of fuel economy on a miles-per-gallon scale is not linear, as more miles-per-gallon (mpg) are initially better for your wallet and the planet than you might expect, and eventually trail off with diminishing returns. Last week, a friend pointed out a good blog post by Nicholas Chase and the Energy Information [...]

I am one of those people who always thought Barcelona would be my favorite city in the world. I visited several times, and though the weather, design, and food leave you wanting little else, there was always something about the sheer number of tourists (besides myself) and traffic that put me off the whole experience.

If Climate Change Was Not Real…

… there would be a lot of other environmental issues to deal with. This is no big revelation, but it’s a question I’ve been pondering recently: What is the state of the world, not counting climate change? Or rather, what if we managed to reduce CO2 emissions to necessary levels, what would our focus be on [...]

Imagine There’s No Garbage. I Wonder If I Can.

In the U.S. we throw away about 70% more garbage per person than in Sweden.

In John Lennon’s iconic song “Imagine,” he paints a world without war, greed or hunger. I’d like to add garbage to his list. Yup, plain ol’ trash. It’s everywhere. It’s persistent, and as the name implies, it’s dirty. When scanning the globe to check out ways different countries address this problem, I pause at Sweden. [...]

A little while ago, President Obama revealed the details of his Climate Action Plan, which describes the first-ever federal regulations on restricting carbon dioxide (CO2). The plan has three main prongs, and many minor ones. The first is to cut CO2 emissions stateside. The second is to “prepare the U.S. for the impacts of climate [...]
