Tree-of-heaven ( Ailanthus altissima ) is spreading widely throughout West Virginia and threatening the native forest ecosystems in Appalachia. This invasive plant was introduced to the United States from China in the 1780s. The same exotic tree species was also introduced to Japan in 1860s but is not aggressive in this country. In Japan, particularly in the Kyushu Island, tree-of-heaven is rarely found in natural forest ecosystems but a few trees may be found growing in university campuses (i.e. Kyushu University), school premises and house backyards. Tree-of-heaven was initially ...

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 ...

Sometimes, part of being a scientist is dealing with the unexpected. During research projects, scientists might get very surprising results. Or, something might happen to completely change the scope of the project. This is exactly what happened to a group of scientists in Chile . Scientists were studying how man-made armoring, such as seawalls, impact the ecology of beaches in Chile and California. They had surveyed 9 beaches in Chile when something very unexpected happened on 27 February 2010– an 8.8 magnitude earthquake hit .

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 ...
Many of the world’s glaciers, such as the Exit Glacier in Alaska, United States and Pasterze Glacier in Austria, have lost mass due to melting over the past few years. One such glacier, Exploradores in southern Chile, is also disappearing. This glacier is a sight to behold – a 20 kilometer frozen mass that is filled with cliffs of luminescent blue and indigo ice.

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 ...
A fun and easy way to be involved in the Student Climate Research Campaign (SCRC) is by participating in the Climate and Land Cover (CLC) Intensive Observing Period (IOP). This quarterly IOP focuses on documenting and uploading land cover data into the GLOBE database. Scientists are then able to use these data to validate land cover in climate models. Knowing the right type of land cover is important to climate models, because it plays a role in both the energy and hydrologic cycles. For example, land cover plays an important role in how much solar energy is ...

All over the United States, spring flowers such as daffodils and crocuses began blooming nearly a month ago due to an unseasonably warm winter. Some of my friends from many parts of the country have been mentioning how beautiful their gardens are and enjoying the warm weather. Even my family and friends from the Mid-Atlantic region have been sending photos showing off their beautiful home gardens.

One important part in the scientific inquiry process that often gets overlooked is the step to communicate and share your research findings. There are many ways that scientists share their research with each other and the community, including writing reports and publications, presenting research at conferences and meetings, and sharing their science with the community via the media. The Internet age provides a number of great new ways for us to share science information, such as with blogs, online discussion forums, webinars, and by sharing videos.
To encourage everyone ...

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 ...
Since the end of January 2012, Europe has been experiencing record-breaking cold temperatures and heavy snowfalls. Temperatures are dropping to -40°C (-40°F) and below in Europe. The canals of Venice are freezing over (the first time since 1991) and sections of the Black Sea have frozen (the first time since 1977). And, Rome has received its first substantial snowfall since 1986.

Communities in the Sahel region of Africa depend on trees for firewood, food, building materials, and even medicine. Anecdotal observations in this savannah climate, a transition region to the south of the Sahara Desert, have suggested the number of trees is decreasing. A recent study by a group of researchers at the University of California at Berkeley has provided scientific support indicating that trees are indeed dying and the decline is being attributed to climate change. Scientists looked at aerial photos dating back to 1954, satellite images, climate change ...
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 ...
From January 22 to 26, 2012, scientists from around the world gathered for the American Meteorological Society annual meeting, which was held in New Orleans, Louisiana. Scientists from the GLOBE Program stayed next to the beautiful Mississippi River.

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 ...

When you think about farms, you may think of the sounds you hear. Those sounds may include both natural and manmade sounds, such as the rustling of produce in the wind or machines working the fields. While these are expected sounds that can indicate farm health, scientists recently have been looking at another natural sound: songbirds.
Farmers are becoming more interested in looking at the key connections between ecological, economic, and social components to managing their farms, according to Quest science blog . It is then important to make sure that clear and ...
