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 ...

Have you ever watched a newscast and the on-air meteorologist mentions “according to our weather models, our best chances for rain will occur between the hours of 6 and 9 pm”? Have you wondered what exactly are those models they’re talking about?
A weather model is a series of equations that take a look at an initial state of the atmosphere (such as the temperature, ...

Establishment and proliferation of invasive species in an environment where they were introduced is becoming a worldwide problem. During my trip to Kyushu University in Fukuoka, Japan in 2008 for a research fellowship, I was able to observe the same plant species that is also considered invasive in the United States. It is called the tree-of-heaven ( Ailanthus altissima ). This trip initiated a project involving a more in-depth investigation of the competitiveness of Ailanthus as an invasive plant. With the involvement of undergraduate students in the Department of Land Resources at ...

This post is the second in a series called “Trees in Trouble”. To see the first post in this series click here .
Climate impacts so many things on this planet, most notably the types of flora and fauna that live in a specific region. And for those creatures that have annual cycles tied to the local climate, such as the hibernation of bears, migration of birds, and life cycles of insects, a change in climate can shift their way of life and even have subsequent consequences on the environment they live in.
Take the pine beetle (Dendroctonus ponderosae) for ...
Just over four years after my first visit to Australia (From drought to flood down under: Part I), the tides have turned and the country has gone from experiencing the driest decade on record to having the wettest two-year period on record in 2010-2011. These recent rains have been both a blessing and a curse. The good news is that they helped the region of southeastern Australia start to recover from the long drought (see Figure 1). The bad news is that the rains came on heavy and strong. In January 2011, devastating floods occurred across southeastern ...
In December 2007, I arrived in Australia for the first time ever. It was a critically dry period for the region, as they were in the midst of a terrible drought. Immediately upon my arrival, there were signals of a community in dire straits. Instead of advertisements for products and services, the signs in the airport were encouraging water conservation. My hotel bathroom had a message affixed to the mirror asking me to limit my shower time and water usage. The dams were drying up and many communities faced running out of water in just mere months. As ...
This week we have a guest blogger, Dr. Dixon Butler. Dr. Butler was the GLOBE Chief Scientist from 1996-2003 and now works as a consultant to NASA.

The general explanation of the scientific method focuses on comparing two situations that differ in only one clearly defined way. One case serves as the control while the other is the experiment. The results must be replicable as a check that the measurements were made correctly and that any other differences between the control and experiment are insignificant. This is an ...
If you’ve seen the science news headlines in the past few weeks, you may have noticed stories summarizing how 2011 ranked in climate history. What is interesting is that the headlines have been a bit contradictory. For example, if you’ve read the story as reported by the National Aeronautics and Space Administration (NASA), the headline reads “ NASA finds 2011 ninth-warmest year on record ”, which to me implies it was another record hot year given that it made the top ten list. Nonetheless, another story reported in ABS news touts that the world wasn’t quite ...
Last week’s GLOBE Scientists’ blog, “Peculiar weather – just because it sounds odd doesn’t mean it didn’t happen!” talked about inquiry-based learning. If you have a great question and decide to investigate further, how can you share your results? Sharing results is an essential part of the scientific method. If scientists didn’t share their work, how would we know what has already been done? Or what is already known? One of the best options for young scientists to share results is to participate in a science fair. Science fairs often occur in ...

I have always been passionate about the weather. When I realized that to fulfill this passion I had to have a career in atmospheric science, I started acquiring all sorts of books, charts, movies, and other weather related things. One of those books was a book from the early 1990’s called It’s Raining Frogs and Fishes by Jerry Dennis. It was really interesting to me because it discussed all of the different seasons and some different phenomena that different parts of the world experience during the seasons. As I continue to blog for The GLOBE Program, my mind ...
