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 ...

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 ...

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 ...

This week we pick back up on our Full Circle Superior Series. In 2010 Mike Link and Kate Crowley chose to walk around the largest fresh water lake in the world – Lake Superior which has shoreline in both Canada and the United States. This 1555 mile/145 day walk was the first ever by a couple and the first to attempt to stay on the shoreline. Because Mike and Kate are educators in their sixties they wanted ...

To say that the journey to the summit of Mt. Kilimanjaro was a success would not do justice to the wonderful personal and scientific experiences the team had. From taking the first steps toward the summit on Sunday 23 September to summiting the following week and boarding flights to return home, each team member gained something that will stay with them forever.

As you may have noticed, the Scientist Blog was quiet for the past two days. As is to be expected, things can change rapidly on the mountain and the ability for the team to send us their daily blogs was interrupted. The team safely continued on their journey, and have sent us their blogs.
Day Eight was Saturday, 29 September. The team journeyed from 4,877 m (16,000 ft) to 5,608 m (18,399 ft). ...

Today the team continues on their journey to the summit of Mt. Kilimanjaro by traveling from the Karanga Camp, situated at 3,962 m (12,998 ft), to the Kossovo Camp at 4,877 m (16,000 ft). This leg of the journey takes the team back to the alpine desert biome.

A morning at camp
The team is now over halfway done with their trek to the summit of Mt. Kilimanjaro in Tanzania. The journey began on Sunday 23 September as the team left Basecamp and hiked to Forest Camp. You can read all about their journey starting here .

Today marks another transition between biomes – from heath zone to alpine desert. An alpine desert is a harsh, dry, windy region that consists of mostly bare rock and ice. Temperatures during the day can soar to 38°C, while at night can be below freezing. The air is very thin, which results in labored breathing as well as more intense solar radiation. The Lava Tower camp sits at approximately 5,029 m (16,499 ft). ...

Today the team will hike from Shira 1 Camp to Moir Hut (Shira 2 Camp on the map below). This part of the journey will take the team further into the heath zone. As discussed yesterday , the heath zone is a zone of sparse vegetation due to lower rainfall amounts.

Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2012/09/24/xpedition-day-three-forest-camp-to-shira-1-camp/
Today the team heads from 2,438 m to 3,505 m above sea level. This portion of the journey will take the team from rain forest to heath zone. A rain forest is characterized by high rainfall, with annual totals ranging from 1750-2000 mm (68-78 in). A heath zone is above the forest line, where porous soils and lower rainfall result in sparser vegetation.
Leaving the rain forest heading to the heath zone ...

Packed and ready for the journey
Today, Sunday, 23 September, the team packs up the vehicles and heads off on their journey. Their itinerary for the day includes a few hours’ drive from basecamp followed by a 3 hour hike to Forest Camp, located at 2,438 m above sea level.

Beginning on 23 September, five GLOBE students, teachers and scientists and one GLOBE alum will join commence on a journey through the biomes of Mt. Kilimanjaro in Tanzania, Africa. Known as, “the Xpedidion,” the 2012 trek marks the fifth year of this exciting journey. This year will be bigger than ever as a documentary film crew will join us. In addition, we will be sharing images via ...

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 ...
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.

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 ...
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 ...
