Global Warming

[USMCDevilDog]

Now, I know this might just be some Liberal topic that they only think about or it may not. But, I was watching a program about Global Warming on the History Channel the other day and it scared the living crap out of me from what they're saying could happen in the next 5 to 20 years if this keeps on going.

The thing that caught my ear the most was the forecast of a Modern Ice-Age, which is right around the corner if this continues. During Summers, if haven't noticed already, it's getting much much hotter. I quote "The world has been at its hottest ever the past 15 years and getting hotter in the last 5." This past year the temperatures during summers have risen up by 7 Degrees. If that continues then it will be unbearable for human life to survive during the Summers and late Springs, even more so during the Winters from the Ice Age.

Now maybe they're just blabbing their mouths and its just them worrying too much, but I'm just saying what I heard and it scares me thinking that that's in our lifetime.

This is some serious shit.

I've seen science on both sides of this issue but it's hard to believe that with the increase in human population and the burning of fossil fuel for energy wouldn't increase global warming to a certain extent. How much? Who knows. Guess the question is really how to deal with it.

Global Warming Data that Riled Doubters Confirmed
January 04, 2017 - A new independent study shows no pause in global warming, confirming a set of temperature readings adjusted by U.S. government scientists that some who reject mainstream climate science have questioned.

The adjustments, made by the National Oceanic and Atmospheric Administration in 2015 to take into account changes in how ocean temperatures have been measured over the decades, riled a House committee and others who claimed the changes were made to show rising temperatures. The House Science Committee subpoenaed the agency's scientists and then complained that NOAA wasn't answering its requests quickly enough.

The new international study looked at satellite data, readings from buoys and other marine floats for ocean temperatures. Each measurement system independently showed the same 20 years of increase in temperatures that NOAA found: about two-tenths of a degree Fahrenheit per decade since 2000, said the study's lead author, Zeke Hausfather of the University of California, Berkeley. “Our research confirms that NOAA scientists were right,” Hausfather said. “They were not in any way cooking the books.”

President Barack Obama looks at Bear Glacier, which has receded 1.8 miles in approximately 100 years, while on a boat tour to see the effects of global warming in Resurrection Cove in Seward, Alaska​

NOAA adjusted past data to take into account old measurements by ships that often recorded temperatures from their engine rooms, where heat from the engines skewed the data. Buoys and satellite data don't have such artificial warming, Hausfather said. In 1990, about 90 percent of the ocean temperature readings were done by ships, now it is about 85 percent by the more accurate buoys, Hausfather said.

Scientists Andrew Dessler of Texas A&M University and Kevin Trenberth of the National Center for Atmospheric Research, who weren't part the original study or the more recent one that confirmed its conclusions, called both accurate. “This paper further allays any qualms that there may have been scientific errors or any non-scientific agendas,” Trenberth said in an email. Officials at the House Science Committee did not respond to repeated requests for comment. Hausfather's study was published Wednesday in the journal Science Advances.

Global warming could steal postcard-perfect weather days
January 18, 2017 | WASHINGTON (AP) — Global warming is going to steal away some of those postcard-perfect weather days in the future, according to a first-of-its-kind projection of nice weather.

On average, Earth will have 10 fewer days of mild and mostly dry weather by the end of the century, the researchers estimate. Some places will get more days perfect for picnics or outdoor weddings, while other places will lose a lot. Rio de Janeiro, Miami and much of Africa are big losers, while Europe and Seattle will gain nicer weather. "It's the type of weather where you can go outside and do something fun," said study lead author Karin van der Wiel, a meteorology researcher at Princeton University and the National Oceanic and Atmospheric Administration . "It's not too cold. It's not too hot. It's not too humid." For the past three decades, the world has averaged 74 mild days a year. But by 2035 that will shrink to 70 and then 64 by the last two decades of the century, according to the study, published Wednesday in the journal Climatic Change . Mild weather was defined as between 68 and 86 degrees (18 and 30 degrees Celsius) with low humidity and no more than a trace of rain.

Any change depends on where you live and the time of year. For example, on average, the U.S. will lose nine mild summer days by the end of the century, although most is gained back with more mild days in the winter, spring and fall. The report estimates that Washington, Chicago, New York and Dallas will lose two weeks of pleasant summer weather but some is gained back. On average, Washington loses 13 mild days; Atlanta, 12; Chicago, 9; Denver and New York, 6; and Dallas, 1. The biggest losers will be the tropics and nearly all of Africa, eastern South America, South Asia and northern Australia. Rio de Janeiro, on average, will see 40 mild days disappear. Miami will lose its only mild summer day and nearly a month of spring and fall mild days by 2100. "The changes are more dramatic in parts of the developing world, where you have high concentrations of populations," said NOAA climate scientist and co-author Sarah Kapnick.

Other places, especially northern developed ones, will gain some of what the tropics lost. England and northern Europe are big winners. Seattle should pick up nine mild days and Los Angeles, which already has a lot of nice weather, gets six extra by the end of the century. The scientists didn't specifically focus on whether the loss of mild days has already started globally, but they did see it happening in much of Africa and South America, Van der Wiel said. Climate scientists usually focus on extreme weather — record heat, tropical cyclones, droughts, floods — and how they could get worse as the world warms. Kapnick said she wanted to look at nice weather because her friends kept asking her what day to choose for good wedding weather. The team used a middle ground scenario for global warming — not worst-case runaway carbon pollution and not dramatic cuts in emissions of heat-trapping gases — and ran different computer simulations to see what would happen.

It's not just fewer nice days to enjoy. Fewer mild days will also harm agricultural production and allow disease carrying insects to thrive more in more places, said University of Georgia meteorology professor Marshall Shepherd. Stanford University climate scientist Chris Field, who led an international study of extreme weather, questioned the purpose of the study: "Extreme conditions are the sharp end of the climate stick. It is in the extremes when things break and damage occurs." National Center for Atmospheric Research scientist Gerald Meehl, who also studies extreme weather, said a decrease in mild weather may not quite have the economic and health costs but there are other factors such as tourism "or simple human enjoyment."

Danish Think Tank: $9B Cloud Project Could Prevent All 21st Century Global Warming
January 24, 2017 – Instead of collectively spending $100 billion annually under the 2015 Paris Climate Agreement to combat global warming, developed nations should consider investing just $9 billion in a marine cloud whitening project that could prevent global warming for the rest of the 21st century, according to Bjorn Lomborg, director of a Danish think tank.

Marine cloud whitening mimics the effects of a volcanic eruption by inserting salt particles into the atmosphere to make clouds denser so they reflect more sunlight back into space. “Spending just $9 billion on 1,900 seawater-spraying boats could prevent all the global warming set to occur this century,” Lomborg, director of the Copenhagen Consensus Center, writes in a January 18 column for Project Syndicate, adding that the benefits the project would generate would be worth an estimated $20 trillion. “This is the equivalent of doing about $2,000 worth of good with every dollar spent,” he pointed out.

“To put this in context, the Paris climate agreement’s promises will cost more than $1 trillion annually and deliver carbon cuts worth much less – most likely every dollar spent will prevent climate change worth a couple of cents,” Lomborg continued. “Even climate activists increasingly recognize that the lofty rhetoric of the global agreement to reduce greenhouse-gas emissions, concluded in Paris just over a year ago, will not be matched by its promises’ actual impact on temperatures,” he said. “This should make us think about smart, alternative solutions.” “All of the global warming for the century could be avoided” by using geo-engineering such as marine cloud whitening, according to a working paper by Americans J. Eric Bickel and Lee Lane for the CCC, which “has commissioned 21 papers to examine the costs and benefits of different solutions to global warming.”

Warning that such technology “is not ready for deployment” and “even base case estimates for many important benefit and cost parameters are unknown,” Bickel and Lane estimate a 5,000-to-1 direct benefit-cost ratio for a marine cloud whitening project, which would use unmanned GPS-navigated ships to spray seawater into ocean cloud formations. According to the co-authors, “reflecting into space only one to two percent of the sunlight that strikes the Earth would cool the planet by an amount roughly equal to the warming that is likely from doubling the pre-industrial levels of greenhouse gases.” Pointing to the 1991 eruption of Mt. Pinatubo in the Philippines, which “reduced global mean temperature by about 0.5% C,” they wrote that “scattering this amount of sunlight appears to be possible.”

In addition, the expected research and development costs for a marine cloud whitening geoengineering project “are clearly quite low. Indeed, they appear to be almost negligible,” the study’s co-authors noted. “People are understandably nervous about geoengineering,” Lomborg acknowledged. “But many of the risks have been overstated. Marine cloud whitening, for example, amplifies a natural process and would not lead to permanent atmospheric changes – switching off the entire process would return the world to its previous state in a matter of days.” Reversability is important because Bickel and Lane point out that one of the negative effects of “changing global temperatures without lowering the level of GHG [greenhouse gas] concentrations…. is the possible lessening of rainfall.”

Global warming outpacing forecasts
Fri, Dec 08, 2017 - BIGGER CHALLENGE: By tracking how much sunlight gets bounced back into space, the study showed that the more alarming projections are clearly aligned with that data

The UN’s forecast for global warming is about 15 percent too low, which means end-of-the-century temperatures could be 0.5?C higher than previously predicted, a study released on Wednesday said. The prediction makes the already daunting challenge of capping global warming at “well under” 2?C — the cornerstone goal of the 196-nation Paris Agreement — all the more difficult, the authors said. “Our results suggest that achieving any given global temperature stabilization target will require steeper greenhouse gas emissions reductions than previously calculated,” they wrote. A half-degree increase on the thermometer could translate into devastating consequences. With only 1?C of global warming so far, the planet has already seen a crescendo of deadly droughts, heatwaves and super storms engorged by rising seas.

The UN Intergovernmental Panel on Climate Change, which provides the scientific foundation for global climate policy, projects an increase in the Earth’s average surface temperature of about 4.5?C by 2100 if carbon pollution continues unabated, but there is a very large range of uncertainty — 3.2?C to 5.9?C — around that figure, reflecting different assumptions and methods in the dozens of climate models the panel takes into account. “The primary goal of our study was to narrow this range of uncertainty and to assess whether the upper or lower end is more likely,” said lead author Patrick Brown, a researcher at the Carnegie Institution for Science at Stanford University in California. By factoring in decades of satellite observations which track how much sunlight gets bounced back into space, the study showed that the more alarming projections are clearly aligned with that data and the warming that has been measured so far. “Our findings eliminate the lower end of this range,” Brown said. “The most likely warming is about 0.5?C greater than what the raw model results suggest.”

One scientist not involved in the research described it as a “step-change advance” in the understanding of how hot our planet is likely to become. “We are now more certain about the future climate, but the bad news is that it will be warmer than we thought,” University of Reading professor of meteorology William Collins said. The study, published in the journal Nature, not only narrows the temperature range, but reduces the degree of uncertainty as well. “If emissions follow a commonly used ‘business as usual’ scenario, there is a 93 percent chance that global warming will exceed 4?C by century’s end,” coauthor Ken Caldeira said.

Up to now, there was barely more than a coin-toss certainty that the Earth would breach the 4?C barrier by 2100 under that story line, but even if one assumes a more optimistic future in which humanity rapidly accelerates the global economy’s transition from “brown” to “green” energy, the findings still apply, the authors said. “We should expect greater warming than previously calculated for any given emissions scenario,” they wrote. Brown and Caldeira “have checked and corrected all the models, revealing they underestimated potential warming by up to 15 percent” City, University of London climatologist Mark Maslin said. “This means international action to keep global temperature below 2?C, or even 1.5?C [an aspirational goal in the Paris Agreement], will require cutting carbon emissions deeper and faster.”
