expedition clothing expedition clothing Drought and Dead Trees

History is rich with lessons, but will political hubris take heed of past civilizations annihilated by drought? The Akkadi expedition clothing an, Moche, Tiwanaku, Mayan, and Anasazi to name but a few are well documented in our history books.

When speaking this week to colleagues in Texas on the brutal drought gripping the South and estimated 60 million dying or dead trees in expedition clothing the seven counties surrounding Houston a city normally contending with deluge, not drought I was struck by the fact that neither the state nor the feds have any plans currently in place to deal with climate disruption.

Droughts are enveloping regions worldwide, and killing mature forests on every forested continent. And every climate model that I have seen predicts that as greenhouse gases rise from the burning of fossil fuels so too will the incidences of drought.

Theres 180 million acres of Ponderosa pines spreading across the West and up until 90 years ago surface fires ignited by lightning burned at least once a decade. As a result these ecosystems developed some nifty traits to adapt to these fast moving surface fires. Footthick bark and holding the first live branches 18 feet or so above the surface enabled them to easily grow with the occurrence of wildfires. With a Smokey Bear fire policy in place to extinguish all fires our Ponderosa forests are now overcrowded, sickly, waterstarved and awaiting the insatiable pine bark beetles.

Several proposals have been put forward by leading restoration scientists to thinout these forests; they are the life force providing clean air and a safe water supply to millions of citizens, industries and agriculture across the West. Problem. The lawmakers refuse to acknowledge the science irrefutably showing that releasing 82 million metric tons of greenhouse gases daily on Earth are forcing the climate. These are the same lawmakers, I might add, that welcome the innovative science enabling them to use their smart phones, itablets and flat screen televisions.

Instead of embracing the Ponderosa thinning program which would create at least a million jobs and protect four million homeowners who back into these urban/wildland tinderdry forests, the lawmakers have chosen to support a pipeline from the Alberta tar sands to increase rather than decrease Americas colossal carbon footprint. Perhaps even more confounding is why collectively the big five oil companies are still eligible f expedition clothing or a $21 billion subsidy, annually. Their quarterly profits, particularly in this economy, certainly dont warrant any taxpayer dollars.

As temperatures on Earth continue to rise unintended consequences of climate change are becoming more life threatening. For example, this week in Nature climate scientists showed one of the paradoxes of global warming; that is, as surface temperatures rise, upper stratospheric temperatures plummet and lingering banned in 1987 chlorofluorocarbons created a hole over 770,000 square miles bigger than the combined area of Alaska and Idaho in the ozone layer above the Arctic. A hole in the ozone layer above the Arctic has never been witnessed before. will increase, dramatically.

Another major unintended consequence of rising greenhouses gases in the Northern Hemisphere, in particular western North America, has been the removal of the ecological cold barrier in the mountains enabling hundreds of billions of ravenous bark beetles an opportunity to kill billions of mature pine trees. The loss of the high elevation whitebark and limber pines creates a very serious problem for retaining winter snowpacks, which feed water supplies for 40 million of people, industries, agriculture and critters across the West.

Field biologists are trained to observe natures patterns. southern United States and death of billions of trees across the West. The lawmakers are well advised to listen to field biologists whose only agenda is to maintain the genetic tapestry of life on our planet. Are the lawmakers in Washington, DC intending to plan for climate disruption? If not be forewarned: Failing to plan is planning to fail.

Please dont dignify this lunatic failed hypothesis with the word Theory. All the wordspinning in the world cant change the fact that human caused climate change is a hoax meant to enslave the world. The IMF gave the game away at Copenhagen when instead of rich countries paying poor countries, they ALL would have to pay 2% of GDP to the IMF which would give the money to the World Bank which would lend it out at interest. Thinning trees will impact the other species of biological diversity that welcome the trees and plants as homes/habitat, food, shelter, cover and nurseries. As trees not only sequester heat trapping gases, they evapotranspire water vapor that cools the leaves, soil and surrounding area. When the soil is disturbed and the trees removed, the sequestered C02 will be released.

Once the soil is disturbed, something will grow in the vacated soil, and these opportunistic, nonnative weeds transported from around the world will quickly take over in the soil. These weeds are annuals and dry out, just in time for fire season. The dried, dead weeds/straw not only fail to provide for and support the existence of the native biological diversity, they cause hotter, faster and more intense wildfires. Fewer trees will also permit more sunlight to reach the Earth and the soil while destroying habitat for the forests strands in the web of all life.

Deforestation also heats up and dries out the climate and less evapotranspiration. The trees and plants are biological diversitys food, shelter, provide bird nesting sites and homes for the entire ecosystem.

Yes, fire is a natural component of ecosystem maintenance. Wildfires provide minerals for the soil, and many species evolved with fire. The CA sequoia trees seeds cannot establish without fire as the fire burns off a thick coating on the seed that must be removed. expedition clothing
