Scientists Uncover Evidence Of Impending Tipping Point For Earth

JR: If we stay anywhere near our current greenhouse gas emissions path, we will cross many climate tipping points this century. Trapped Antarctic Methane Could Escape, Worsen Warming. Swamp gas trapped under miles of Antarctic ice, a chemical souvenir of that continent's warmer days, may someday escape to warm the planet again, an international team of researchers report in Nature this week. The researchers suggest that microbes isolated from the rest of the world since the ice closed over them, some 35 million years ago, have kept busy digesting organic matter and making methane—a much more effective greenhouse gas than carbon dioxide. If global warming causes the ice sheets to retreat in the coming decades or centuries, the researchers warn, some of the methane could belch into the atmosphere, amplifying the warming.

Panel’s Warning on Climate Risk: Worst Is Yet to Come. Photo YOKOHAMA, Japan — Climate change is already having sweeping effects on every continent and throughout the world’s oceans, scientists reported on Monday, and they warned that the problem was likely to grow substantially worse unless greenhouse emissions are brought under control.

Panel’s Warning on Climate Risk: Worst Is Yet to Come

The report by the Intergovernmental Panel on Climate Change, a United Nations group that periodically summarizes climate science, concluded that ice caps are melting, sea ice in the Arctic is collapsing, water supplies are coming under stress, heat waves and heavy rains are intensifying, coral reefs are dying, and fish and many other creatures are migrating toward the poles or in some cases going extinct. The oceans are rising at a pace that threatens coastal communities and are becoming more acidic as they absorb some of the carbon dioxide given off by cars and power plants, which is killing some creatures or stunting their growth, the report found.

It’s been a bummer couple of weeks when it comes to apocalyptic climate change news.

Find climate change terrifying? Stephen Colbert has a refreshing solution

First, the National Climate Assessment came out, letting us know that, hey, climate change got our invitation and may be showing up a little early to the party – in fact, it’s already in the corner eating all the dip, guzzling all the drinks, and trying to light the couch on fire. Then, that darn West Antarctic ice sheet decided it had enough and is in irreversible collapse. How to get Republicans to stop using the “I’m not a scientist” dodge. In 2012, when Sen.

How to get Republicans to stop using the “I’m not a scientist” dodge

Marco Rubio (R-Fla.) was asked by GQ how old the Earth is, he demurred, “I’m not a scientist, man.” This was not a smooth move. It made him sound like a dumb frat boy. You don’t need to be a scientist to know the Earth is roughly 4.54 billion years old, any more than you need to be a scientist to know the Earth is round or it revolves around the sun. 119 One-Liners to Respond to Climate Science Myths. How to talk to a conservative about climate change. Our climate change debate is stuck in a “left-wing ghetto.”

How to talk to a conservative about climate change

That was one provocative conclusion reached during a high-level panel of politicians, environmental thinkers, journalists and business people in London, England. “[Twenty] years of ‘awareness raising,’ grandiose pleas to save the planet, lots of talk about sacrifice, apocalyptic messages and photos of polar bears,” a recent summary report explained, “have trapped climate change in a niche that it urgently needs to break out of.” Recent polling numbers support the panel’s claims. Experts Surer Than Ever of Manmade Global Warming. Oslo.

Experts Surer Than Ever of Manmade Global Warming

Climate scientists are surer than ever that human activity is causing global warming, according to leaked drafts of a major UN report, but they are finding it harder than expected to predict the impact in specific regions in coming decades. The uncertainty is frustrating for government planners: the report by the Intergovernmental Panel on Climate Change (IPCC) is the main guide for states weighing multibillion-dollar shifts to renewable energy from fossil fuels, for coastal regions considering extra sea defenses or crop breeders developing heat-resistant strains. IPCC Surer Than Ever About Human-Caused Climate Change. But the international panel of experts is less sure how that will affect people in specific places. Coal Plant A Intermountain Power Project coal-burning plant in Utah Utah Geological Survey What debate ? A recent draft of an international consensus report offers stronger-than-ever evidence that global warming is driven by human activity.

The report also adjusts its expectations for important climate change effects such as how much sea levels will rise, while admitting the difficulty in estimating what will happen to individual cities in the age of climate change. Reuters recently got a hold of a draft of the Intergovernmental Panel on Climate Change's next report, the first stage of which is due in September. The panel's estimates for future warming are important to policymakers. Global warming is real, and it’s our fault — let’s fix it.

Global warming is real, and it’s our fault — let’s fix it

We did it. Why we care about the 97% expert consensus on human-caused global warming. Three distinct studies using four different methods have independently shown that the expert consensus on human-caused global warming is 97 ± 1%.

Why we care about the 97% expert consensus on human-caused global warming

The result is the same whether we ask the experts’ opinions, look at their public reports and statements, or examine their peer-reviewed science. Even studies that quibble about the precise percentage have accidentally reinforced the 97 ± 1% consensus. The evidence is crystal clear that humans are the main cause of the current global warming, and the expert consensus reflects the strength of that body of evidence. It’s not easy to convince 97% of scientific experts about anything – that requires some powerful scientific evidence. And yet public opinion is a very different story. The sources of this disparity and how it can be corrected are the subjects of an intense debate amongst social scientists.

Whenever the temperature plunges dramatically and there's heavier snowfall than usual in some states, people will cite the arctic weather as proof that global warming is a hoax.

Short Answers to Hard Questions About Climate Change

Is there anything I can do? Fly less, drive less, waste less. You can reduce your own carbon footprint in lots of simple ways, and most of them will save you money. Electronic Waste. Alex Lin - Turning E-Waste Into E-Treasure. Alex Lin was a boy who was just reading the newspaper one day.

He read an article about something called e-waste. He learned that it is the waste generated as people upgrade electronic devices. When people are done with things like computers, phones, mp3 players, etc. and throw them away, that’s e-waste. He also learned that e-waste is dangerous to the environment. Yet this was not something that was not widely known. Piles of thrown-out TVs, laptops and phones pose an environmental risk.

Christmas gifts from past years meet a sad end at Absolute Green Electronics Recycling in California. Computers are dismantled. Their parts get sorted into cardboard bins. One bin holds nothing but hard drives. High-Tech Trash. June is the wet season in Ghana, but here in Accra, the capital, the morning rain has ceased.

As the sun heats the humid air, pillars of black smoke begin to rise above the vast Agbogbloshie Market. I follow one plume toward its source, past lettuce and plantain vendors, past stalls of used tires, and through a clanging scrap market where hunched men bash on old alternators and engine blocks. Soon the muddy track is flanked by piles of old TVs, gutted computer cases, and smashed monitors heaped ten feet (three meters) high. Beyond lies a field of fine ash speckled with glints of amber and green—the sharp broken bits of circuit boards. I can see now that the smoke issues not from one fire, but from many small blazes.
