Luke 12:56 (KJV) Ye hypocrites, ye can discern the face of the sky and of the earth; but how is it that ye do not discern this time?

MATTHEW 24-8 (KJV) All these are the beginning of sorrows.

Repent of your sins and come to Christ, the Kingdom of God is near!!!

Extreme Summer Temperatures Occur More Frequently

Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business as usual schedule of emitting greenhouse gases.

By analyzing observations and results obtained from climate models, a study led by Phil Duffy of the Lawrence Livermore National Laboratory showed that previously rare high summertime (June, July and August) temperatures are already occurring more Read more…

Climate change threatens tropical birds

Rainbow-billed toucans like the one shown here normally are confined to lower elevations in Costa Rica, but global warming is allowing them to colonize mountain forests, where they compete with resident birds for food and nesting holes, and prey on their eggs and nestlings.

SALT LAKE CITY — Climate change spells trouble for many tropical birds – especially those living in mountains, coastal forests and relatively small areas – and the damage will be compounded by other threats like habitat loss, disease and competition among species.

That is among the conclusions of a review of nearly 200 scientific studies relevant to the topic. The review was scheduled for online publication this week in the journal Biological Conservation by Çağan Şekercioğlu (pronounced Cha-awn Shay-care-gee-oh-loo), an assistant professor of biology at the University of Utah.

There are roughly 10,000 bird species worldwide. About 87 percent spend at least some time in the tropics, but if migratory birds are excluded, about 6,100 bird species live only in the tropics, Şekercioğlu says.

He points out that already, “12.5 percent of the world’s 10,000 bird species are threatened with extinction” – listed as vulnerable, endangered or critically endangered by the International Union for Conservation of Nature (http://www.redlist.org).  Şekercioğlu’s research indicates about 100 to 2,500 land bird species may go extinct due to climate  Full article here

2011 Was A Year of Weather Extremes, With More to Come

The global average temperature in 2011 was 14.52 degrees Celsius (58.14 degrees Fahrenheit). According to NASA scientists, this was the ninth warmest year in 132 years of recordkeeping, despite the cooling influence of the La Niña atmospheric and oceanic circulation pattern and relatively low solar irradiance. Since the 1970s, each subsequent decade has gotten hotter — and 9 of the 10 hottest years on record have occurred in the twenty-first century.

Each year’s average temperature is determined by a number of factors, including solar activity and the status of the El Niño/La Niña phenomenon. But heat-trapping gases that have accumulated in the atmosphere, largely from the burning of fossil fuels, have become a dominant force, pushing the Earth’s climate out of its normal range. The planet is now close to 0.8 degrees Celsius warmer than it was a century ago. Hidden within Read more…

OP-ED Expanding Deserts, Falling Water Tables and Toxins Driving People from Homes

WASHINGTON, Aug 23, 2011 (IPS) – People do not normally leave their homes, their families, and their communities unless they have no other option. Yet as environmental stresses mount, we can expect to see a growing number of environmental refugees. Rising seas and increasingly devastating storms grab headlines, but expanding deserts, falling water tables, and toxic waste and radiation are also forcing people from their homes.

Advancing deserts are now on the move almost everywhere. The Sahara desert, for example, is expanding in every direction. As it advances northward, it is squeezing the populations of Morocco, Tunisia, and Algeria against the Mediterranean coast.

The Sahelian region of Africa – the vast swath of savannah that separates the southern Sahara desert from the tropical rainforests of central Africa – is shrinking as the desert moves southward. As the desert invades Nigeria, Africa’s most populous country, from the north, farmers and herders are forced Read more…

Record-Breaking Heat

Midland is officially in the midst of the hottest summer on record.

With a high temperature of 100 degrees Friday, the record for 100-degree days in one year is now 53, breaking the old mark of 52 previously set in 1964. With triple-digit temperatures expected through the weekend, the hot conditions will continue into the first part of the school year.

Midland experienced 21 days of triple-digit temperatures in 2010.

Texas drought will harm wildlife habitat for years

Texas drought will harm wildlife habitat for years (AP)

Turkey vultures drop in for a drink from one of the very few remaining watering sources on a private ranch that spans over 7,000 acres Saturday Aug. 6, 2011, near San Angelo, Texas. Randy Bolf, a fence contractor and rancher that leases the property for his cattle herd said that all of the rain and run-off watering tanks on the ranch that straddles Tom Green and Coke county have dried up and area wildlife and his cattle rely on the artificial watering sources he maintains on the property.

(AP) — In a muddy pile of sand where a pond once flowed in the Texas Panhandle, dead fish, their flesh already decayed and feasted on by maggots, lie with their mouths open. Nearby, deer munch on the equivalent of vegetative junk food and wild turkeys nibble on red harvester ants – certainly not their first choice for lunch.

As the state struggles with the worst one-year in its history, entire ecosystems, from the smallest insects to the largest predators, are struggling for survival. The foundations of their habitats – rivers, springs, creeks, streams and lakes – have turned into dry sand, wet mud, trickling springs or, in the best case, large puddles.

“It has a compound effect on a multitude of species and organisms and habitat types because of the way that it’s chained and linked together,” said Jeff Bonner, a wildlife biologist with the Texas Parks and Wildlife Department.

Since January, Texas has only gotten about 6 inches of rain, compared to Read more…
