Sea temperatures around the Great Barrier Reef have increased over the last 150 years, contrary to claim at Wattsupwiththat
Claim:
"Great Barrier Reef Sea Surface Temperature: No Change In 150 Years"
Prediction by Extinction Rebellion's Roger Hallam that climate change will kill 6 billion people by 2100 is unsupported
Claim:
I am talking about the slaughter, death, and starvation of 6 billion people this century—that's what the science predicts.
Financial Post commentary jumps to unsupported conclusions in claiming “climate change isn’t causing extreme weather”
“This article is misleading since it confuses changes in climate change impacts with changes in climate and weather extremes and it subjectively selects examples that support its message.
There is clear scientific evidence that many weather and climate extreme events increase in intensity and frequency due to anthropogenic climate change. Munich Re, for example, publishes data on global major extreme events in its annual reports.”
Meme image falsely claims wind turbines produce less energy that is used to build them
Claim:
A windmill could spin until it falls apart and never generate as much energy as was invested in building it.
Commentary in The Australian by Ian Plimer relies on false claims to make its case
“If you think that potentially causing hundreds of millions of refugees and trillions of dollars in damages is fine because some plants did well in the same conditions millions of years ago when humans weren’t around, then you could support this article.”
Breitbart article baselessly claims a study of past climate invalidates human-caused climate change
“By the reasoning of this article, if a rock rolled down a hill three million years ago, no human can be responsible for rolling a rock down a hill today. The fallaciousness of this reasoning is astounding.
It is hard to imagine that a well-intentioned person can so profoundly misunderstand the science. Assuming the author is acting in good faith, this article provides evidence that motivated reasoning can produce results that appear delusional to well-informed people.”
EPA’s Scott Pruitt incorrectly suggests climate change might not be “a bad thing”
Claim:
We know that humans have most flourished during times of, what, warming trends. I think there are assumptions made that because the climate is warming, that that is necessarily a bad thing.
Some extreme weather events are clearly becoming more common, in contrast to Lord Lawson's claim
Claim:
The IPCC, the Intergovernmental Panel on Climate Change, which is sort of the voice of the consensus, concedes that there has been no increase in extreme weather events.
Lord Lawson falsely claims that global temperatures have declined over last decade
Claim:
according, again, to the official figures—during this past 10 years, if anything, mean global temperature, average world temperature, has slightly declined
Earth is not at risk of becoming a hothouse like Venus, as Stephen Hawking claimed
Claim:
Trump's action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid.
The world’s coral reefs are severely threatened by climate change and other human impacts, as ABC story notes
Claim:
90 per cent of the world's coral reefs will disappear in the next 35 years due to coral bleaching induced by global warming, pollution and over-development.
Analysis of "Ocean acidification: yet another wobbly pillar of climate alarmism"
The scientists who have analyzed the article show that it contains significant inaccuracies, notably for its core assumptions, and misrepresents scientific studies and scientists it cites to make its point. Reviewers also note that the article knocks down strawman arguments that do not represent the state of scientific knowledge (scientists do not claim the ocean will become a “giant acid bath”).
Ocean acidification is expected to harm marine ecosystems overall, cherry-picking can lead to the opposite conclusion
Claim:
Marine life has nothing whatsoever to fear from ocean acidification.
Oceans are currently acidifying, claims to the contrary contradict observations
Claim:
there has been no reduction in oceanic pH levels in the last century
Analysis of "James Lovelock: ‘Before the end of this century, robots will have taken over’"
“Extraordinary claims demand extraordinary evidence, and Lovelock has not even come up to the standards of providing what the scientific community would consider to be ordinary evidence. The journalist did not balance Lovelock’s statements with a set of clear statements saying that the vast majority of informed climate scientists (as, for example, represented by the IPCC reports) have reached consensus on conclusions that are diametrically opposed to what Lovelock is saying, and that the IPCC scientists have backed up their statements with a wealth of empirical data, whereas Lovelock is largely opining without providing any substantive evidence to support his rather extraordinary claims.”
Analysis of "Flooding of Coast, Caused by Global Warming, Has Already Begun"
“The theory of sea-level rise and flood problems is pretty well understood — this makes the point that this theory is also happening now and can only be expected to get worse — sea levels have been rising on the US east coast for the last 150 years or more and even if current trends simply continue, impacts will continue to grow. As the article states, we actually expect a significant acceleration of sea-level rise in the coming decades meaning the impacts will grow more rapidly.”
Sea level could rise by as much as 1 or 2 meters (3.3-6.6 feet) by the year 2100
Claim:
Sea level rise could reach six or seven feet by the year 2100.
Analysis of "What science can tell us about the links between global warming and massive heat waves"
“This is a well-written article that provides a good overall discussion around the connection between climate change and the ongoing US heat wave. In the absence of a specific event attribution study the role of climate change in this event can’t be quantified, but Chris Mooney provides an insightful overview of the role of climate change in heat events generally.”
Analysis of "Scientists warn of 'global climate emergency' over shifting jet stream"
“This article makes little sense. It uses scientific jargon, such as in the last paragraph, to make it sound “scientific”, but uses it so loosely that it has no meaning. I do not see any logic behind these wild claims, there are no connections with established research, and there is no discussion of statistical certainty. Moreover, wild attributions to anthropogenic climate change are made without any backing.”
Analysis of "Thanks to climate change, the Arctic is turning green"
“The article reports about recent evidence that terrestrial ecosystems are ‘greening’ in response to human activities, principally the increasing atmospheric CO2 concentration. The author presents this ‘greening’ as a new finding while annual global carbon budgets have reported that about 25% of the fossil-fuel emissions have been taken up by the biosphere since the 1960s. Nothing is fundamentally wrong in the article but it is organized in a somewhat misleading way”
Analysis of "Great Barrier Reef may perish by 2030s…"
This Mashable article reports on new preliminary research that finds the ongoing coral bleaching event in the Pacific is mainly due to human-caused global warming, and that if global warming proceeds as currently expected, “large parts” of the Great Barrier Reef could die by the mid-2030s. Six scientists have reviewed the article and conclude that it is overall accurate and in agreement with the science.
Analysis of "What we’re doing to the Earth has no parallel in 66 million years, scientists say"
“It sadly implies that even the PETM, a massive warm climatic excursion, might not be harsh enough to represent an analogue for future climate change, as the Washington Post rightfully points out.”
Analysis of "Scientists are exaggerating carbon threat to marine life"
“This article misses some major intellectual points about ocean acidification, thanks to what seems to be a willful misunderstanding and misquoting of an interview with Dr. Browman on an Ocean Acidification special issue journal.”
Analysis of "Scientists say human greenhouse gas emissions have canceled the next ice age"
“The article presents an accurate account of recently published research which suggests that human-induced global warming will delay the onset of the next ice age by 50,000 years. The research supports the findings of several studies published over the past 15 years, and is consistent with the scientific consensus that human activity is changing the climate with very long-term consequences.”
