As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing so on a wide range of time and space scales.
In a recent video post, Neil deGrasse Tyson said,
“One of the great things about science is that it is an entire exercise finding what is true. You ...

Concerns regarding the impact of global warming on vector-borne diseases have intensified interest in the relationship between atmospheric factors and dengue fever incidence. Global climate change poses the threat of serious social upheaval, population displacement, economic hardships, and environmental degradation. Changes in temperature, rainfall and relative humidity have potential to enhance vector development, reproductive and biting rates, shorten pathogen incubation period and encourage adult longevity. In addition, changes in wind direction, velocity and frequency will have an ...

Beste mensen,
Het effect van de uitzonderlijk zachte winter op de natuur is ook bij de media niet onopgemerkt gebleven. In de uitzending van het KRO programma Brandpunt op zondag 16 maart komt het onderwerp aan bod. Zie http://gemi.st/KN_1656575 . Het item begint op 23:20. Verder zat ik op zondag 9 maart in het programma Jinek op Zondag. Dit is terug te zien op http://gemi.st/KN_1656819 . Tenslotte zat ik op woensdag 19 maart in het EO-programma 'Melk en Honing'. De uitzending is terug te bekijken op http://gemi.st/EO_101212300 .
Vriendelijke groeten,
Arnold

With climate change, there are many relationships that are understood, and many others that are not. Dr. Veerabhadran Ramanathan from The Scripps Institute in San Diego has spent the last fifteen years in the Maldives, a nation south of India that is comprised of over 1,200 islands, studying the relationship between air pollutants, cloud formation and air temperature.
The Maldives are a great location for ...

A couple of years ago, I attended a seminar sponsored by the Climate and Global Dynamics Division (CGD) of the National Center for Atmospheric Research (NCAR) on how climate change is threatening the survival of wolverines ( Gulo gulo ). This scientist, Synte Peacock from CGD, painted a gloomy outlook for this ferocious creature after using a climate model to examine changes in spring snow cover and summer air temperatures. However, recent legislative proposals may make the future a little brighter.

Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/30/an-interesting-relationship-soil-temperature-and-climate-change/
It seems common place that warmer air temperature leads to warmer soil temperature. And while this relationship seems intuitive, the effect isn’t always studied, especially with respect to the response from microorganisms. That is why researchers are investigating what happens when the soil temperature increases.

Through our trees in trouble series, we’ve examined trees in the Sahel zone in Africa and the United States . This problem, climate change and dying trees, has been seen on every continent, the only exception being Antarctica, due to the lack of vegetation on the frozen continent. Scientists have recently found that there is an alarming loss rate of big, old trees, whose ages range ...

Blog previously posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/16/a-tale-of-two-extremes/
Weather extremes have become a common theme in the news headlines the past few weeks. For example, nearly every part of the United States has been experiencing one of two extremes – either frigid cold or record-breaking high temperatures. Places like Arizona and California experienced below-freezing temperatures, which can have potential impacts on the crops grown in these typically balmy regions. In contrast, cities in the Southeast U.S., such as ...

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.

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.

Monday, 1 October was the final day of The Xpedition. After an exciting summit day, the team continues on their descent and is picked up to head back to Arusha, where they will enjoy a well-deserved meal.

Throughout the entire journey, the team relied on the use of porters, who are local Tanzanians who carry equipment up the mountain. These porters are essential to a ...

On Sunday, 30 September, the team made it to the summit of Mt. Kilimanjaro. The summit sits at 5,895 m (19,340 ft) above sea level. What a fantastic accomplishment for the team!

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.

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.
