Climate, Climate change, and Global warming

Facebook Twitter

Global warming is the term used to describe the current increase in the Earth's average temperature.

Climate change refers not only to global changes in temperature but also to changes in wind, precipitation, the length of seasons as well as the strength and frequency of extreme weather events like droughts and floods.

Climate Change Linked to Waterborne Diseases in Inuit Communities

As global warming triggers heavier rainfall and faster snowmelt in the Arctic, Inuit communities in Canada are reporting more cases of illness attributed to pathogens that have washed into surface water and groundwater, according to a new study. The findings corroborate past research that suggests indigenous people worldwide are being disproportionately affected by climate change. This is because many of them live in regions where the effects are felt first and most strongly, and they might come into closer contact with the natural environment on a daily basis. For example, some indigenous communities lack access to treated water because they are far from urban areas.

Series How to Talk to a Climate Skeptic: Responses to the most common skeptical arguments on global warming. Climate change denial. Climate change denial, or global warming denial, involves denial, dismissal, or unwarranted doubt about the scientific consensus on the rate and extent of global warming, the extent to which it is caused by humans, its impacts on nature and human society, or the potential for human actions to reduce these impacts.[1][2] Climate change skepticism and climate change denial form an overlapping range of views, and generally have the same characteristics; both reject to a greater or lesser extent current scientific opinion on climate change.[3][4] Climate change denial can also be implicit, when individuals or social groups accept the science but divert their attention to less difficult topics rather than take action.[5] Several social science studies have analyzed these positions as forms of denialism.[6][7][8] Terminology The terminology emerged in the 1990s.

Climate change denial

History A conservative reaction built up, denying environmental concerns which could lead to government regulation. Pseudoscience. Scientific opinion on climate change. Global mean land-ocean temperature change since 1880, relative to the 1951–1980 mean.

Tobacco Science, Climate Denial, and “Free Speech” Not long ago, newly discovered documents revealed that, way back in the 70s, and even before, Exxon scientists were studying the potential impacts of fossil fuel burning on global climate.

Tobacco Science, Climate Denial, and “Free Speech”

(see video at end of this piece) Now, a group of Attorneys General is starting to ask why, when they knew the science, Oil giants started paying groups like The American Enterprise Institute, the Heartland Institute, and others, to confuse and deny the facts, and misinform customers and investors. Having been caught out – the dodge we are now seeing is that denying climate science when you know the truth – is exercising “free speech”. Practically a patriotic duty, fer gosh sakes. Some friends were doing a little searching in the Tobacco archives for examples of how Tobacco apologists were playing the “our right to free speech” card when caught out lying about what their own scientists knew on the effects of Tobacco products. Rare ice data collected by early 'citizen scientists' confirms warming.

MADISON, Wis. -- In 1442, 50 years before Columbus "sailed the ocean blue," Shinto priests in Japan began keeping records of the annual freeze dates of a nearby lake.

Rare ice data collected by early 'citizen scientists' confirms warming

Along a Finnish river, starting in 1693, local merchants recorded the date the ice broke up each spring. These observations are among the oldest inland water ice records in human history, and now they are contributing to modern understanding of climate change. According to a new study published in Nature Scientific Reports, the meticulous record keeping of these historical "citizen scientists" reveals increasing trends toward later ice cover formation and earlier spring breakup since the start of the Industrial Revolution. "These data are unique," says John Magnuson, a researcher and emeritus professor at the University of Wisconsin-Madison's Center for Limnology.

The Temperature Spiral Has an Update. It’s Not Pretty.

If you think the heat is on in our current climate, you ain’t seen nothing yet. To recap, University of Reading climate scientist Ed Hawkins wrecked the internet a few weeks ago with a revolutionary new way to look at global temperatures. Using a circular graph of every year’s monthly temperatures and animating it, Hawkins’ image showed planetary heat spiraling closer to the 2°C threshold in a way no bar or line graph could do.

Recalculating the Climate Math. The new numbers are startling.

Recalculating the Climate Math

Only four years ago, I wrote an essay called “Global Warming’s Terrifying New Math.” After record 2015, a dire warning for our climate future. Video series has short interviews with climate scientists to help with denial. Anton Brand/Shutterstock One of the problems with debunking climate change deniers is that they reuse old, long-debunked claims over and over, even long after those claims are shown to be wrong. Marshall Shepherd, the 2013 president of the American Meteorological Society, called these “zombie ideas,” rising from the dead to walk to the Earth again. It’s an apt term … and whack-a-mole comes to mind as well.* Happily, there are tools at our disposal that help.

Climate change in charts: from record global temperatures to science denial. Much has been written about climate change in recent months, what with that record-breaking hot year we just had and the qualified success of the Paris climate talks. But if there’s one criticism I’d have of the media coverage, it’s this. Not enough graphs. So here are six that you might have missed, but that tell us a few things about the state of the climate and the state of the public’s thinking on global warming. So how have global temperatures been recently? You know, while human-caused global warming has been on that pause that didn’t happen.

Above is a chart from the UK’s MetOffice showing the three main global temperature data sets. Climate Change. Climate change deniers swarm Bill Nye's Facebook page, NASA shows up to help smack them down. Everyone’s favorite Science Guy, Bill Nye, shared an article on his Facebook page about famous climate denier Marc Morano refusing to take a $20,000 bet offered by Bill Nye about whether the planet will continue getting hotter. Consensus. Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

Statement on climate change from 18 scientific associations "Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.
