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 ...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2 mm of rain fills the inner tube to a depth of 2.0 mm, which one can read.
In addition, if heavy rainfall fills the inner cylinder, the rest of the rainfall overflows into the outer cylinder, ...

This time was my first visit to Trinidad and Tobago and to the LAC region. The visit was first of its kinds, knowing vividly that Africans and the People of Trinidad and Tobago have so many things in common in terms of Geography and Historical antecedent. The motivation for my visit to Trinidad and Tobago started during the 17 th GLOBE Annual meeting at Maryland. Initially, it was just a brief discussion with Henry Saunders (Country Coordinator, GLOBE Trinidad and Tobago). However, after a year, I met Mr. Michael at GLOBE Expedition in New Delhi, India where we had in-depth ...

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 ...

In most scientific research an important test is whether the results of an experiment can be repeated, typically repeated by another lab and research group. A result that cannot be confirmed in this way is generally viewed as invalid. This is a great test for controlled experiments where virtually identical experimental conditions may be achieved.
In Earth science research involving observations of the natural world, experimental conditions cannot be reproduced. For environmental research the standard must switch for repeatable to intercomparable – capable of being compared. ...

In the early 1980’s, I chaired a group of scientists exploring the idea of a comprehensive satellite mission to study all aspects of the global environment. The group was diverse with expertise covering the range of Earth science disciplines from geology, ecology, oceanography, limnology, glaciology, and atmospheric science and their various sub-disciplines. Their first recommendation was take today’s data today.
In all of Earth science there is the recognition that we have only one Earth to study. How Earth works is revealed by watching it change in a comprehensive manner and ...
We had an incredible turn out at our (the GLOBE) table at the NOAA booth at the NSTA conference. It was great to meet so many teachers and curriculum directors with an interest in GLOBE. Thanks to everybody who took the time to stop by and learn about GLOBE.
For those people who did not get the Earth System Science Poster , we are very sorry. Please follow this link to get the PDF files so that you can print out the pages to use in your classroom. The page also has a complete poster that can be projected or printed, and the activities guide.
Expanding on the ESS poster ...

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
