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%. 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.
10 Things That Don’t Disprove Global Warming 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. During the cold snap in early 2014, for example, businessman Donald Trump tweeted derisively, "This very expensive GLOBAL WARMING bull---- has got to stop. Ourplanet is freezing, record low temps, and our GW scientists are stuck in ice" [source: Mooney]. That's not too surprising, actually, since psychological research has found that people's views about climate change tend to be influenced by the weather on the day that they are interviewed [source: Konnikova]. One flaw with this way of looking at things, as Columbia University atmospheric scientist Adam Sobel has pointed out, is that there's a big difference between the weather on a particular day and the climate, which is the pattern of what happens over a much longer time.
Climate Change and Global Warming for Children Introduction to Climate change Many people make Climate Change and Global Warming a scary and difficult thing to understand, but it’s not. Scientists have warned that the world's climate has changed a lot, and has affected many living and non-living things. Scientists Uncover Evidence Of Impending Tipping Point For Earth By Climate Guest Contributor on June 10, 2012 at 2:42 pm "Must-Read: Scientists Uncover Evidence Of Impending Tipping Point For Earth" Image: Cheng (Lily) Li. JR: If we stay anywhere near our current greenhouse gas emissions path, we will cross many climate tipping points this century.
Short Answers to Hard Questions About Climate Change 3. 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. You can plug leaks in your home insulation to save power, install a smart thermostat, switch to more efficient light bulbs, turn off the lights in any room where you are not using them, drive fewer miles by consolidating trips or taking public transit, waste less food, and eat less meat. Perhaps the biggest single thing individuals can do on their own is to take fewer airplane trips; just one or two fewer plane rides per year can save as much in emissions as all the other actions combined.
Weather Wiz Kids weather information for kids Climate What is climate?Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere. 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.
Global warming is real, and it’s our fault — let’s fix it EDITORIALS August 20, 2013 5:20PM storyidforme: 53814643 tmspicid: 19835014 fileheaderid: 9082689 Updated: September 22, 2013 6:25AM It’s us. 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. 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.

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 ? Find climate change terrifying? Stephen Colbert has a refreshing solution It’s been a bummer couple of weeks when it comes to apocalyptic climate change news. 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. “It is so terrifying,” Stephen Colbert says, “that it left a carbon footprint … in my pants.”
Experts Surer Than Ever of Manmade Global Warming Oslo. 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. Drafts seen by Reuters of the study by the UN panel of experts, due to be published next month, say it is at least 95 percent likely that human activities – chiefly the burning of fossil fuels – are the main cause of warming since the 1950s. That shifts the debate onto the extent of temperature rises and the likely impacts, from manageable to catastrophic. “I talk to people in regional power planning.
How to get Republicans to stop using the “I’m not a scientist” dodge In 2012, when Sen. 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. How to talk to a conservative about climate change Our climate change debate is stuck in a “left-wing ghetto.” 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. Less than half of Britons firmly believe human activities are causing climate change, Angus Reid data from this spring suggested. The figures were similar for Americans.
