How bad is the global temperature from global warming now?

Answer 1

The temperature has changed 1-degree over the past 100 years sounds pretty dam stable to me.

Answer 2

In the past 100 years, global warming has caused an increase in the global average air temperature somewhere between .32 degrees Fahrenheit and 1.3 degrees Fahrenheit, according to the International Panel on Climate Change (IPCC).

The IPCC is the world's body of international scientists, climatologists, and metorioligists studying global warming and its effects.

Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between in the next 100 years-- 1990 thru 2100.

Answer 3

It's just like child abductions.

Did you ever notice how many Amber alerts there are these days? Does that mean suddenly, in the past few years, we've had a sudden huge outbreak in the number of child abductions? NO. In fact, it's declining.

The difference is, in the past, the media never focused on it except for the rare case that piqued their "interest". Now, it's regularly reported by law.

It's the same with "global warming". Take a look at photographs from history over the past 100 years. You'll discover stretches of several years of incredible cold weather and huge blizzards, followed by stretches of sweltering heat, record high temps, draughts and dust storms. Followed by, surprise, more record lows and blizzards and climactic "turmoil".

Every generation is near-sighted. They think HISTORY BEGAN as of the day they were born. That's why they refer to things as "the worst EVER".

It's funny, many of the people in the environmental movement like to point to the past 10 or 100 years as undeniable proof of climate change, the WORST EVER, as if the past 50 million years of dramatic and drastic climate change never happened, but yet those same people are the first to mock devout Judeo-Christians for their belief that the earth began only 5000 years ago. THEY'RE DOING THE SAME THING!

That's why I call them EnviroFundamentalists. Whether they realize it or not, it's become a religion.

Answer 4

A 1 to 2 degree rise in the world's yearly average temp might not seem like much to many people. There are signs that things are changing. Some places that cool climate plants like ferns, show signs that these plant populations are gradually to abruptly dieing to extinction. I've thought something's been wrong while I've been out fishing for several decades. Many birds for example, used to fly to South America, or Florida for the winter. Now, Canada geese, for example seem to not fly south. Why not? I doesn't stay cold for long periods like our winters used to. Even if it's below zero, geese allways can find some open water all winter. Plus, man has bulldozed and removed wetlands, marshlands, and geese have man-made open waters to stay at all year. All these things add up to warmer trends. In Chicago recently, we had sveral periods of strong to severe weather heavy rain events predicted. Instead, it didn't even rain, or missed Chicago entirly. Climate change is worse than ever.

Answer 5

Something like 2 degrees since the Mini Ice Age ended.

Answer 6

The actual temperature is not the real issue. One or two degrees increase is all it takes to cause major changes in the weather systems. Has anyone noticed the weather is a little off lately?

Answer 7

I haven't Sean any records broken yet. In Texas it rained for 9 consecutive days but the record is 10 days.

Answer 8

I believe it's about 2 degrees warmer worldwide. Different studies have different results.

Answer 9

real bad, just wait for more record breaking temperatures.

Answer 10

More heat ahead for sweltering West.

The drought and floods in some areas is killing agriculture and human ecology.

HELENA, Mont. - An oppressive heat wave eased a bit in some parts of the West, but forecasters predicted little relief in the days ahead for a region where many cities have baked in triple-digit temperatures.

The National Weather Service issued a red flag wildfire warning for Saturday in eastern Utah and western Colorado, where temperatures were again expected to approach or top 100.

Extreme heat plagued much of Idaho, Nevada, Utah, Oregon and Washington state again on Friday. In Montana, where cattle outnumber residents by more than 2 to 1, livestock and people sought the shade and drought-weary farmers watched for damage to grain.

"We are trying to get our hay up before it disintegrates," said cattle rancher Sharon McDonald near Melville. "It just gets crispy and just falls apart."

Air conditioners — and even swamp coolers — were predictably hot sellers at the hardware store.

"I'm telling you, it has been nuts," said Dennis VanDyke, a manager at Power Townsend in Helena. "The only thing I am getting calls for is air conditioners."

VanDyke said some people prefer swamp coolers, which use a fan and the evaporation of water to cool the air, over the more power-hungry air conditioning units. "They are being bought faster than we can put them on the shelves," he said.

In Montana, temperatures above 100 degrees are usually not seen until August. The normal July high in Helena is 83 degrees — not the high 90s seen Friday. Triple-digit records were set or tied in Great Falls and Billings at 104 degrees each. The mercury reached 105 in the north-central Montana town of Havre, 106 at the Gallatin Field Airport near Bozeman and 107 in Missoula.

In Utah, high school teacher Lois Wolking said she was escaping the summer heat by heading indoors. Temperatures were down a few degrees in Salt Lake City on Friday, but still hovered around 100.

"A swamp cooler, Netflix and reading is how we're surviving," the 58-year-old East High teacher said.

But the heat will hover over most of the far West through at least the end of next week, said Kelly Redmond, a regional climatologist for the National Weather Service. He said it could migrate farther inland and cover more of the West, including Colorado, as the week goes on.

"It looks like it is going to stay place for a good long while," he said.

Boise hit 105 degrees Friday after a high temperature of 104 on Thursday. Lewiston reported a high of 101 on Friday and Pocatello hit 102.

Idaho Power, the state's largest utility, set a record Friday for electricity consumption for the second consecutive day, as triple-digit temperatures continued across much of Idaho.

The company's peak load reached 3,142 megawatts at 4 p.m., topping the previous record set Wednesday of 3,120 megawatts. The old record, 3,084 megawatts, was set in 2006.

Anne Alenskis, a spokeswoman for Idaho Power, said the company has kept records for at least 90 years.

Temperatures were expected to ease slightly in Southern California. Phoenix saw a modest drop, a somewhat cooler 112 degrees compared to 115 on Thursday. With the approach of Arizona's summer rainy season, humidity levels have started climbing along with power demand.

Heat remained an issue along the border. The bodies of six suspected illegal immigrants have been found since Monday in southern Arizona deserts, all likely victims of heat illness while trying to walk into the U.S. from Mexico. The toll, while high, is not unusual during hot spells in the region.

In eastern Oregon, which set 15 record highs on Thursday, temperatures largely dropped to the high 90s. In the center part of the state, population growth and a burgeoning demand for air conditioning meant a rise in electricity demand. The Bonneville Power Administration said it was worried fires could damage transmission lines and cause outages.

In California, heat was mostly confined to inland regions, with triple-digit readings in the Sacramento and San Joaquin valleys. The mercury topped 100 in the Woodland Hills area of Los Angeles' San Fernando Valley and in the high desert cities of Lancaster and Palmdale, while out east by the Colorado River, the little city of Needles sweltered in 115-degree heat.

But temperatures in most of Los Angeles and the populous Southern California coastal zone were in the 70s and low 80s, while San Francisco and Monterey Bay cities were even cooler.

The National Forest Service reported at least 16 fires over 500 acres in size burning throughout the West, including three new ones that sparked Thursday.

The agency said fire danger was most extreme in Arizona, California, Oregon and Utah — although a "red flag" warning was posted for much of the West.

Arizona Dust Causes Colorado Meltdown

Wind-blown dust from the drought-stricken Southwest can speed the melt of snow in Colorado’s mountains, yet another unpredictable effect of climate change, a new study shows.

In 2006, snows in areas of Colorado's San Juan Mountains above and below the tree line (above which trees can no longer grow), unexpectedly melted a month earlier than usual.


The cause for the premature melt was dust, most likely originally from parched deserts in Arizona and New Mexico, hundreds of miles away.


The dust is less reflective than snow and so reduces the overall reflectivity of the area, allowing for more of the sun’s energy to warm, and subsequently melt, the snow pack. A similar effect of dark soot falling on Arctic snow is thought to speed melting there.


“The connection between dust and lower snow reflectance is already established, but the amount of impact measured and modeled in this system stunned us,” said study team leader Tom Painter of the University of Colorado at Boulder’s National Snow and Ice Data Center. “The fact that dust can reduce the snow cover duration so much—a month earlier—transforms our understanding of mountain sensitivity to external forcings.”


There were eight dust deposition events in 2006, up from only three or four between 2003 and 2005, according to the authors of the study, detailed in the June 23 issue of the journal Geophysical Research Letters.


Snowmelt provides one-sixth of the world’s population with drinking water, and is important to sustain agriculture in the western United States.


The expected exacerbation of western droughts brought about by global warming will likely make the situation snowball.


“Recent studies agree that with global warming, the Southwest will be warmer and drier,” Painter said. “Enhanced dust deposition is likely, further shortening snow cover duration.”


“Ultimately, a warming climate and the dust it generates will affect river run-off and soil moisture in the mountains,” he added. “Not only in the Western United States, but across many of the world’s mountains.”
