NASA CO2 Visualization

I feel like I’ve been asleep at the wheel having missed this excellent video of CO2 emissions over a period of one year. Very helpful, as is the accompanying text.

And, have a look at this one, quite similar, but more dynamic, from Vox.

Ancient world’s uncovered as Siberian permafrost melts

A fascinating glimpse of thousands of years of climate data and biota is being revealed as the world’s largest mega slump or thermokarst develops in Siberia. The Batagaika Crater is north of Irkutsk, Russia and is exactly what climate scientists have been predicting from the increased warming in the Arctic – and is a classic example of positive feedback.

Climate change causes glacial river in Yukon to change direction

from CBC News…

Glacier retreated so much that its meltwater switched course, in an event not documented in modern times.

Climate change has caused the massive Kaskawulsh Glacier in the Yukon to retreat so much that its meltwater abruptly switched direction, in the first documented case of “river piracy” in modern times.

Instead of flowing into the Slims River and then north to the Bering Sea, the water has changed course and now flows south toward the Kaskawulsh River, the Gulf of Alaska and the Pacific Ocean, scientists have found.  Read more…

Weekend Wandering 11: EarthLabs

EarthLanbsCongratulations to Carlton College in Minnesota. Through their Science Education Resource Lab (SERC), they have created dozens of Earth Science labs on their EarthLabs website. The labs are designed for high school students to discover, in their words…

What could be cooler than learning about the planet you live on?

The labs are all online with numerous links to data, graphics and animations.

Even better, they have a corollary site EarthLabs for Educators as a guidebook for teachers using the labs. Included are State and National Science Teaching Standards to make it easier to link the labs into courses.

Take a few minutes or, indeed, a few hours to wander through…

 

Just added – El Niño page

New El Nino page on GeoKnow.net
New ElNino page on GeoKnow.net

As we are in the midst of another El Niño, and the affects are being felt far and wide, I thought GeoKnow.net should reflect that by adding a page devoted to it. There are graphics, videos and links to many sites to help us understand the phenomenon and how it affects people.

 

El Niño and this strange weather we’re having

ElNinoUnprecedented warm weather here in southern Ontario reminds us of the El Niño weather pattern creating it. Here are some backgrounders just added to the main page of GeoKnow.net:

Climate Change done right

It’s quite astonishing that one of the best climate change information sites comes out of a country well-known for its climate change denyers. NASA’s Global Climate Change – Vital Signs of the Planet is excellent. The first menu option is FACTS presenting the evidence, causes, effects and consensus exactly as one would expect from good and proper science. If only my own government could do the same – allow scientists to say what’s really going on. [Aside: For those who don’t know, I don’t live in an oppressive developing nation, but in Canada, where our democratically elected government has been muzzling federal scientists (and here) for years now. Yes, it’s the same Canada of UN peacekeeping fame and the country that once promoted openness, fairness and democracy, but has gone through a difficult time under its current right-wing leadership. Perhaps the Oct 19 election will change that.]

It’s also surprising that a whole government agency (NASA) can be saying something that someone who hopes to be president (Donald Trump) calls a complete hoax

Back to the NASA site: In particular, you will find the Infographics page and the EarthMinute animations helpful, especially in a classroom setting. There are also a number of Interactives to allow some independent exploration of the issue. It’s the kind of site you could spend hours exploring. And if you have contact with Mr. Trump, you may want to suggest he reads this!
