GLOBAL WARMING By Josué David Cano Inzunza Advance 3-4
What is Global Warming ?
Global Warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-20th. Century and its projected continuations.
Global Surface temperature increased 0.74 ± 0.18 °C during the 100 years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the temperature increase since the mid-twentieth century is “very likely” due to the increase in anthropogenic greenhouse gas concentrations.
Effects of Global Warming
Some Impacts from increasing temperature are already happenig.
Ice is melting worldwide.
Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
Sea level rise became faster over the last century.
Precipitation (rain and snowfall) has increased across the globe, on average.
Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up million acres of spruce trees.
Other effects could happen later this century, if warming continues
Sea levels are expected to rise between 7 and 23 inches ( 18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches ( 10 to 20 centimeters).
Hurricanes and other storms are likely to become stronger.
Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
Floods and droughts will become more common.
Less fresh water will be available.
Some diseases will spread, such as malaria carried by mosquitoes.
Ecosystems will change some species will move farther north ir become more succesful.
Solar Energy for electricity and heat
For a long time it has been known that the cleanest energy that exists is solar power – energy from the sun. It is abundant and replenishable – at least, it won’t run out for four or five billion years.
But solar power has a big – and obvious – drawback: It doesn’t work if there’s no sunlight. And in far northern or southern latitudes – especially in winter when days are short – lack of light has been a real stumbling block. Which is what makes the light electric and thermal generator – or LETG – so exciting. The LETG is able to significantly increase efficiency while simultaneously reducing cost. That means the LETG has the potential to greatly extend what solar power can deliver.
The patented GEM – for Generator/Engine/Motor – is a revolutionary design that increases engine efficiency by up to 16 times. Simply stated, it completely changes the game with respect to energy consumption and greenhouse gas emissions. A team of physicists and engineers spent almost a year just doing the physics and design work including computer modeling before any parts were built.
GEM utilizes a rotary design that reduces friction and eliminates wasteful engine component movements. While conventional piston engines waste energy on separate intake and exhaust cycles, the GEM’s rotary design enables continuous cycling in which one stage naturally segues into the next.
