22 Years of Sea Surface Temperatures
The NOAA polar-orbiting satellites (POES) have been collecting sea surface temperature data for over 22 years. This animation is a compilation of that data from January 1985 - January 2007. Of note are the changes in the Gulf Stream, El Nino and La Nina cycles in the Pacific, and the seansonal changes in sea ice cover.

Tropical Plants and Plumeria Care in Temperate Climates
www.howtogrowplumeriafrangipani.com Tropical Plants and Plumeria Care in Temperate Climates. When it comes to growing tropical plants, including plumerias, some gardeners will tell you that these plants cannot be grown in temperate climates. Recently, I have been asked how tropical plants and plumerias can be grown in less than ideal conditions meaning outside their native subtropical and tropical climates. Tropical plant lovers can let their imagination run wild in creating tropical gardens of their own with all the new plants and information that is available to them these days. No longer do they have to listen to all the naysayers telling them it can't be done. Gardeners can create a tropical garden with banana plants, heliconias, plumerias, and other beautiful exotic tropical plants. Many of these tropical plants have been developed and hybridized for this very reason. For example, if a gardener wants to include banana plants in the garden design, instead of growing banana plants that grow twelve feet or more, like Musa 'Monthan', growing dwarf fruiting banana plants is the available and correct choice. When traveling to tropical destinations vacationers encounter heliconias growing in the wild. Many heliconias grow so tall that they would not be considered suitable for container growing. But there are also many smaller heliconias available that can be grown successfully in pots outside during the summer months and inside during the colder months of the year. Plumeria ...

Activists Seek Cooler Place For Polar Bear
www.facebook.com Animal rights activists have stepped up their campaign to urge authorities to move a polar bear in Mexico to another country with a more appropriate environment for an animal from the Arctic. Social media has been a pivotal tool in helping protest organisers push for Yupi, the 20-year-old bear that has lived in a zoo in the northern city of Morelia for her entire life, to be sent to a much colder place in Canada. Adam Raney reports from Morelia on how the "Save Yupi" campaign shows Mexico, like other countries around the world, is moving towards online activism.

Climate Effects on the Pacific Coastal Temperate Rainforest of North America
April 18, 2012 - Session developed by Tom Ainsworth (NOAA Weather Service) and Eran Hood (U. of Alaska Southeast). Presentations by Nicolas Bond (U. of Washington), Roman Motyka (U. of Alaska Southeast), Paul Hennon (USFS PNW Research Station), and Phil Mundy (NOAA Alaska Fisheries Science Center) Session Abstract: The vertical extent of the coastal temperate rainforest and the interactions between the ocean, atmosphere, and coastal mountain ranges results in a large number of climate zones and ecosystems over a relatively small area. The number of ecotones and the sharp gradients between them lead to highly interactive ecosystems including icefields, steep forested hillsides, glacier fed and freshwater streams, wetlands, estuaries, and deep fjords. This session will look at the Tongass region as a whole and describe these closely connected physical and biological systems, how they interact with each other, and how a changing climate will alter the delicate and dependent balance between these systems. Potential societal impacts of a changing climate will be offered followed by an open discussion on how people perceive the changes and how society should respond to them. The main themes of this session are: climate drivers of the Tongass, the historical evolution of Alaska's glaciers, the effects of climate on vegetation, the effects of climate on marine ecosystems, and the public response. This video is from a symposium in Juneau, Alaska from April 17-20, 2012 titled ...

Royal Agricultural Station Angkhang part 1/2 ,Chiang Mai, Thailand ดอยอ่างขาง
The Royal Hill-Tribes Development Programme, at present called The Royal Project, was inaugurated in the year BE 2512 (AD 1969), following His Majesty the King's expressed desire to initiate the benefits of sedentary agricultural practice to the Hill-Tribes community with introduction of substituted cash crops that, in some cases, may fetch higher market prices than opium. During the early stages of the project, His Majesty encouraged the grafting of temperate climate peach scions to the stocks of local species of peach trees. The grafted trees bore fruits that were improved in texture and taste and were hardy enough to withstand long transportation journey to the markets. Other temperate climate fruit scions were also experimemted with at different elevations at the Royal Project's Highland Agricultural Research Stations in various villages in Chiang Mai Province, Phui Village, Mae Chaem District, Khum Village, Fang District, Khun Wang Village, San Pa Tong District, Sam Mun Village, Chiang Dao District, and Mae Tho Village. Located on Tanaosri mountain, Doi Angkhang is just five kilometres from the Thai-Burmese border. The climate is amazingly exotic by local standards. Situated 160 kilometres north of Chiang Mai (40 km from Fang district) and 1400 metres above sea level, Doi Angkhang is cool all year round; temperatures can reach zero Celsius in winter. The weather not only allows cold-climate plants to grow, but it also attracts thousands of visitors to taste the ...

Hierapolis,Pamukkale - Turkey 2012
Hierapolis (Greek: Ἱεράπολις 'sacred city') was an ancient Greco-Roman city in Phrygia located on hot springs in southwest Anatolia. Its ruins are adjacent to modern Pamukkale, Turkey. Hierapolis is a UNESCO World Heritage Site. The hot springs there have been used as a spa since the 2nd century BCE, and people came to soothe their ailments, with many of them retiring or dying here. The large necropolis is filled with sarcophagi, including the Sarcophagus of Marcus Aurelius Ammianos. Part of the archeological site of Hierapolis The great baths were constructed with huge stone blocks without the use of cement, and consisted of various closed or open sections linked together. There are deep niches in the inner section of the bath, library, gymnasium and other closed or open locations. The complex, which was constructed in the 2nd century BCE, constitutes a good example of vault type architecture. The complex is now an archaeological museum. Hierapolis is located in the Menderes River valley adjacent to the modern Turkish city of Pamukkale and nearby Denizli. It is located in Turkey's inner Aegean region, which has a temperate climate for most of the year. See Pamukkale#Geology for more detail Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli Province in southwestern Turkey. The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water. It is located in Turkey's Inner Aegean region, in the River Menderes ...

Plumeria plants are another group of tropical plants thought to be impossible to grow in temperate climates. By providing the correct plumeria care these plants can be grown as far north as Alaska.
If you have fallen in love with tropical plants and want to create your exotic tropical garden oasis in the temperate zone where you reside, go ahead and give it a go. New discoveries and gardening methods have opened the door for new possibilities to grow the garden closest to your heart's desire. http://www.howtogrowplumeriafrangipani.com

SFSP (or North Park as it seems to be more commonly called) was a favorite spot of my wife when we lived in Colorado. It's a great Moose viewing area. This visit, however, we had to head out to the Arapaho Wildlife Refuge to capture the four bulls featured in this piece.
Wiki:
State Forest State Park– A Colorado State Park located in Jackson and Larimer counties east of Walden, Colorado. The 70,838-acre (286.67 km2) park was established in 1970 in the Medicine Bow Range of the Rocky Mountains. Facilities include a visitors center, over 200 campsites, cabins, picnic sites, boat ramps and 94 miles (151 km) of hiking trails. About 52,000 acres (210 km2) of the park are forested in lodgepole pine, douglas fir, colorado blue spruce, aspen and other species. Wildlife in the park includes moose, bighorn sheep, black bear, mule deer and elk.
Arapahoe Wildlife Refuge–The dry climate of the area (at an elevation of approximately 8800 feet) requires the diversion of water from the Illinois River through a complex system of ditches to irrigate wetland meadows and fill water fowl brood ponds. Periodic burning, irrigation and various grazing systems are management tools are used on the refuge meadows to maintain vegetative vigor for nesting purposes. Manipulation of water levels in the shallow ponds is intended to assure adequate aquatic vegetation for food and escape cover. The ponds also produce many insects and other invertebrates (protein) needed by most female waterfowl for successful egg laying. These insects also serve as an essential food item for the growth of ducklings and goslings during the summer months.
The first waterfowl arrive at the refuge in the spring when the ice vanishes in April. The peak migration occurs in late May when 5,000 or more ducks may be present. Canada geese have been reestablished in North Park and begin nesting on the refuge during April. Duck nesting usually starts in early June and peaks in late June. The refuge produces about 9,000 ducklings and 150 to 200 goslings each year. The Fish and Wildlife Service expects that when refuge lands are fully acquired and developed, waterfowl production should increase significantly.
Primary upland nesting species include the mallard, pintail, gadwall, and American wigeon. A number of diving ducks, including the lesser scaup and redhead, nest on the larger ponds and adjacent wet meadows. Most species may be observed during the entire summer season. Fall migration reaches its height in late September or early October when up to 8,000 waterfowl may be on the refuge.
Moose–(North America) or Eurasian elk (Europe) (Alces alces) is the largest extant species in the deer family. Moose are distinguished by the palmate antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal and mixed deciduous forests of the Northern Hemisphere in temperate to subarctic climates. Moose used to have a much wider range but hunting and other human activities greatly reduced it over the years. Moose have been re-introduced to some of their former habitats. Their diet consist of both terrestrial and aquatic vegetation. The most common moose predators are wolves, bears, and humans. Unlike most other deer species, moose are solitary animals and do not form herds. Although generally slow moving and sedentary, moose can become aggressive and move surprisingly fast if angered or startled. Their mating season in the autumn can lead to spectacular fights between males competing for the right to mate with a particular female.
Antelope–The Pronghorn of North America, though sometimes known colloquially as Pronghorn Antelope, is not a member of the family Bovidae, but the family Antilocapridae and not a true antelope. No antelope species are native to the Americas. True antelope have horns which are unbranched and never shed, while Pronghorns have branching horns, and shed annually.

PAMUKKALE TURKEY
Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli Province in south-western Turkey. The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water. It is located in Turkey's Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.
The ancient city of Hierapolis was built on top of the white "castle" which is in total about 2,700 metres (8,860 ft) long, 600 m (1,970 ft) wide and 160 m (525 ft) high. It can be seen from the hills on the opposite side of the valley in the town of Denizli, 20 km away.
Tourism is and has been a major industry. People have bathed in its pools for thousands of years. As recently as the mid 20th century, hotels were built over the ruins of Heropolis, causing considerable damage. An approach road was built from the valley over the terraces, and motor bikes were allowed to go up and down the slopes. When the area was declared a world heritage site, the hotels were demolished and the road removed and replaced with artificial pools. Wearing shoes in the water is prohibited to protect the deposits.

Dr. Eike Luedeling, Climate Change Scientist, World Agroforestry Centre
Rio Conventions Pavilion TV, CBD COP11 (11/10/2012) - Dr Eike Luedeling, Climate Change Scientist at the World Agroforestry Centre, explains how trees can best play a role in mitigating and adapting to climate change.
Luedeling asserts that trees can assist in adaption to climate change by providing a temperate microclimate. He notes that every species seeks out the shade of trees on a hot day and this effect will be even more important for both animals and crops as the impact of climate change increases.
Luedeling explains what he calls the 'portfolio effect', whereby farmers can become economically resilient to the effects of climate change by planting trees. By widening the range of products that they produce to include timber and fruit, Luedeling argues that farmers can earn an additional income that is likely to remain constant even when other crops fail.
Luedeling is careful to emphasise that we must be intelligent in our use of trees for sequestering carbon. If we base calculations on a tree surviving 25 years and, due to being placed in the wrong environment, it dies after 10, any attempt to offset emissions has failed.
Luedeling is also cautious to recognise that we have a limited understanding of trees' responses to climate variability. He maintains that this needs to change if we are to rely on trees to sequester carbon and to continue to provide valuable ecosystem services.

SAVE OUR PLANET - Israel, Jordan, Palestinians mull to build Red-Dead Sea canal
SAVE OUR PLANET... The Dead Sea is dying. The unique water body, also the deepest hypersaline lake in the world, has attracted visitors to its shores for thousands of years where its mineral-rich waters and temperate climate are said to have therapeutic properties. In recent decades, however, the sea level has been dropping at a rate of over a meter per year because the Jordan River, its main tributary, is being diverted along with reduced rainfall and drought further drying its waters. Only around 2% of the Jordan River's natural freshwater reaches the Dead Sea, where it now mixes only with wastewater diverted from fish ponds and salt springs. Jordan and Israel have been working with the World Bank on a plan to save the Dead Sea that involves bringing water from the less-saline Red Sea; however environmentalists fear that mixing the two water body sources could be an ecological disaster. Environmental organization Friends of the Earth Middle East has instead proposed restoring at least 30% of the Jordan River's flow, saying that this could replenish the Dead Sea at a lower financial cost without the potentially adverse environmental consequences. Our appreciation Friends of the Earth Middle East, World Bank, Israel and Jordan for this alert to the precarious situation as well as your efforts to find a way to save the fragile Dead Sea. Let us all step vigorously toward the most eco-friendly solutions for the sake of both human and animal life. Supreme Master Ching Hai has ...
