This is directly addressed by the US Department of Energy at FuelEconomy.gov: It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds [2.9 kg], could produce 20 pounds [9.1 kg] of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. [...] Therefore, to ...

Yes, it was a real article printed in 1912. Although that image of the article seems to have been spliced together so that the paper's name, section, and article are all in one neat little frame, here is a scan of the original paper it came from. That site is run by the National Library of New Zealand, so it is pretty trustworthy. The article in question ...

He did write this on his twitter feed[archived] The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive. See also politifact: Yes, Donald Trump did call climate change a Chinese hoax. He later claimed that this was a joke: Well, I think the climate change is just a very, very expensive form ...

The articles try to do some sleight-of-hand poorly. It goes on at great length about the accepted Milankovitch cycles (mostly taken straight from the NASA article, the same agency which is supposed to be untrustworthy) to pad its scientific credibility. Then leaps to its conclusion while providing no evidence, instead banging on about conspiracies. The ...

This claim is complete and utter bollocks. Let's start with the obvious. If map A has some data on it, and map B doesn't, that in no way indicates that map A is fake - even if data is marked as 'missing. There might be many reasons the data is not on map B. They might have been compiled from different sources, or have different criteria for inclusion, or ...

tl;dr: The supposedly fake map is composed of multiple sources of data, averaged over larger areas of the Earth and a longer period of its history. The map labelled as "the reality" shows just one of these sources of data, plotted at relatively high resolution, and only where directly comparable data is available from a specific 30-year period. Both of the ...

The gross emissions numbers are essentially accurate Here's a chart from the U.S. Energy Information Administration: The World Bank and the International Energy Agency have similar values, but EIA's chart covers a longer period than the World Bank's, and is easier to set up than IEA's. All three data sources cover domestic emissions from fossil fuel ...

tl;dr: The claimed range is 50% higher than the worst assumptions for battery production, and 500% higher than the best assumptions. But it's not an apples to apples comparison. Carbon emissions from battery production The range of values estimated for emissions from battery production varies widely in the literature: In an answer on Sustainability.SE I ...

No. This is not really an infographic that is truthful. It is 'anecdotal evidence' evidence for one farm, very probably not true for that very farm, and in any case a misleading oversimplification. Pasture land can sequester some carbon, yes, but how meaningful is that? Carbon is just the element, and the element is not a greenhouse gas (GHG). Carbon ...

The 24 October 1983 report Projecting Future Sea Level Rise: Methodology, Estimates to the Year 2100 , 2nd edition, predicted (mid-range scenario, see table 4.1 on page 39): by 2000: 8.8-13.2 cm by 2025: 26.2-39.3 cm The mid-range scenario assumed a climate sensitivity of 3.0 degrees C per doubling of CO2 concentration. The mid-range ...

No, the USCRN is not sufficient to provide evidence of any discernible trend The linked article says "as shown in the graph below," and provides this image: This chart plots monthly data points, which is hard to parse just by looking at it. The article does not include any numerical analysis of the data set, or description of what the chart is showing. ...

Technically, yes. Is this an actual measure of anything useful? No. This is an example of an extreme version of data cherry-picking. The explanation is very simple. The level of sea ice fluctuates. 2012 was an extremely bad year for sea ica - really really bad. It was down, at its lowest to barely half what it normally is. Given that, it was absolutely ...

Yes, he absolutely said that. You can still read it on his Twitter feed, in fact, where in November of 2012 he said: The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive. Source: https://twitter.com/realdonaldtrump/status/265895292191248385 Even before that, he made substantially ...

Yes it is logarithmic (although relative to amount of CO2 in a sample volume of gas, not its concentration). No that doesn't invalidate climate change. If you want to read a detailed explanation for both answers, please see Skeptical Science - Is the CO2 effect saturated?. The mistaken idea that the Greenhouse Effect is 'saturated', that adding more ...

If it replaces coal mining for power production, fracking reduces CO2 emissions, but that's not the whole story. Burning anything results in increased CO2 emissions, and methane leaks in fracked gas infrastructure result in CO2 equivalent emissions that erase the gains in reduced CO2 emissions compared to coal. Engel's argument rests on two key assumptions ...

The 1930 measurement was taken incorrectly. The claim was also made in domestic newspapers at the time, including L'Express du Midi: 50° AU SOLEIL A SAINT-ETIENNE Saint-Etienne, 27 août. Le thermomètre a marqué aujourd'hui 50° au soleil. Mme Guilly, 40 ans, est morte frappée d'insolation. A rough translation of this is 50° IN THE SUN IN SAINT-ETIENNE ...

The Daily Mail words their claim as follows: [The yacht skipper Nikki] Henderson's flight from Britain to the US likely produced the same amount of emissions the journey hoped to save, countering Ms Thunberg's mission This incorrectly characterizes the net CO2 gain of the voyage, because Henderson purchased carbon offsets. Of course, carbon offsets are not ...

The 40% figure most likely comes from Pew Research Center: By the year 2050, 41% of Americans believe that Jesus Christ definitely (23%) or probably (18%) will have returned to earth. The figures can be seen here: However, Pew does not make the global warming implication. There is a study by Barker and Bearce about this: the authors show that ...

Water vapor is indeed the most important greenhouse effect contributor.(Ref. 1) It is usually not showing up in climate change discussions because mankind basically has no way of directly affecting the amount of water vapor in the air, either positively or negatively, as anything we could or could not do is utterly dwarfed by natural processes. (As opposed ...

In addition to all the other great answers there is one very important fact that's always ignored in these comparisons (Google translation, lightly corrected by me): The total emissions of petrol and diesel are sugarcoated in this example. For oil extraction, refinery and transport on tankers, in pipelines and trucks 44 kWh of energy was used for ...

There are at least three issues here which contribute to the large differences which Spencer describes. First, there's a highly misleading aspect to the chart. People not familiar with the subject, or who just glance at the chart quickly might conclude that experimental data show essentially no change even though all the climate models are predicting ...

The first point of the question about the actual emissions statistics has already been answered but let me add some information relevant to the second point Secondarily, is it the implied claim that Thunberg is very critical of carbon emissions by the United States but not by China or India true? The claim is clearly very nonspecific but there are a few ...

In a word, no. Weather stations are (as their names suggest) designed for collecting information for weather forecasting (i.e. short term variations in temperature, precipitation etc.), they were never intended for collecting information for climate research (long term statistical behaviour of the weather). As a result, the instruments used tend to have ...

The conference would have presumably been organized by the Climate Research Unit. They have published proceedings for similar conferences going back to at least 1973. It would be ideal to track down the relevant proceedings to identify the exact meeting and paper to which the quote is referring, but this would require some library research. How about other ...

TL;DR: Alexander Graham Bell was concerned with fossil fuels running out, but not climate change per se. Bell was concerned about the inevitable depletion of fossil fuels — “What shall we do when we have no more coal and oil?” So in a 1917 article for National Geographic Magazine, he urged the development of renewable ethanol fuel from agricultural waste, ...

No, it is not true that it invalidates climate change claims, or the need to limit further increases in CO2 concentration specifically as it relates to warming (we can ignore stuff like ocean acidification for this question to keep from wandering too far abroad). First of all, let's look at the source. Is the person an objective scientist, making claims ...

Leaving aside the fact that termite CO2 production is on few, if any, secondary school syllabuses, its more complicated than that. Termites are not burning fossil fuels. The carbon they produce comes from decomposing wood. This carbon came from the atmosphere, and as the wood rots this carbon will wind up back in the atmosphere whether termites eat it or ...

The paper does not claim that that 97% of scientists endorse AGW. The study was conducted to evaluate the consensus within the published literature, and it found that an overwhelming percentage of published papers expressing a view on the question do endorse the premise that human activity is causing global warming. Among abstracts expressing a position ...
