GLOBE’s Earth as a System investigation area cultivates students’ awareness of an intricate web of global connections. Similar to real world scientists, students explore life science concepts, learning that “organisms can only survive where their needs are met.” The Earth as a System investigation area encourages students to observe patterns and connections, such as through phenology. Phenology is the study of how living organisms respond to seasonal changes in their environment. Only through observing and measuring can we notice if changes are occurring and how they occur.

I recently read that the extreme drought in western North America during 2000-2004 actually resulted in more carbon dioxide being released into the atmosphere. In the article in Nature Geoscience, it explained that such droughts can further enhance global warming. When a drought occurs, the plants wither and die and no longer uptake carbon dioxide (normally living plants serve as a carbon sink...

Storm Coming Across US
If you live in the United States, you probably have heard of the snow storm crossing the country right now. There will be mountain snow in the Rockie Mountains, a potential for a blizzard from Nebraska to Wisconsin and then some snow to the Great Lakes states.
The National Weather Service (NWS) definition of a blizzard is:
"A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer:
Sustained wind or frequent gusts to 35 miles an hour or greater; and
Considerable falling and/or blowing snow (i.e.,...

When you examine a seashell, a crystal, the skin of a snake or the wings of a butterfly, what do you think about? Art? Science? Or the obvious connection between the two? At the fall meeting of the American Geophysical Union (AGU) in San Francisco, CA last week, thousands of scientists, including myself, found ourselves examining the intersection of science and art through a wide variety of presentations and...
Lane Community College will be embarking on a comprehensive water quality study for Russel Creek Watershed. It owns property near the headwaters of the creek and it passes through sensitive wetlands that LCC also owns. We will monitor water quality monthly upstream and downstream from the campus as instruments are acquired. Russel Creek is an ephemeral stream. First measurements 12-07-12 at the upstream sampling site near the LCC Learning Garden (our SWS-06 site).
The GLOBE surface temperature field campaign started this week with some record warm temperatures in the United States. Students in much of the United States enjoyed short sleeve weather for several days.
Schools have started to post observations on the GLOBE website. The GLOBE website has been changed dramatically over the last year. The GLOBE Program Office will be adding all teachers in a bulk transfer from the old database in the near future. Many teachers have also signed up on the GLOBE webpage http://www.globe.gov and the help desk has set them up so they can enter data. The help...

In the first post in this series, we looked at what ENSO is. Remember that the atmosphere and oceans are always moving, and in general, those movements follow a specified pattern. When the movement deviates from normal, to either an El Niño or La Niña, weather conditions in different regions of the world will respond.
But who feels these effects first? Usually, equatorial countries that border the Pacific Ocean. But even these countries can...

One of the most significant technology improvements in modern life is our ability to accurately forecast future events. Weather forecasts now routinely extend for five days. The recent flooding on the East Coast of the United States was forecast days in advance. The cause was an unusual merger of two storms to create a super storm – Super Storm Sandy. Atmospheric models correctly predicted that a winter storm coming from the north and a weakening...
Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2012/11/14/esno-basics-what-is-it/
Through many posts here on the Scientists’ Blog, we, in one way or another, discuss ENSO. ENSO, or El Niño-Southern Oscillation, is a quasi-periodic climate pattern that occurs in the tropical Pacific Ocean. When the conditions change, the atmosphere responds in many different ways. In certain locations, it is cloudier and it rains more, while in others it’s clear and dry. Through our “ENSO Basics” series, we’ll take a look at ENSO in many...

A few years ago I attended a workshop for early career scientists to discuss frontiers in integrated water-climate-society vulnerability and adaptation science. This interdisciplinary area of science focuses on the need for using scientific information to not only identify communities that are vulnerable to climate change, but to also help create effective approaches for communities to adapt to climate change. Since every society...
