Geologists On Global Climate Change

[jc456]

you're exactly right, I have a problem with adjusted data sets in reference to temperature across the globe. Yep, fact. I cry foul at every graph because of it. I'm sure you've seen them all.and yet, you and yours wanted me to prove my claim that all datasets shown are adjusted. What a bunch of nut jobs. My god man, if you know it and proud of it, then stand tall and pronounce when I claim it as such. why do you retreat into a hole and shimmer and shake like I have lied? what a bunch of friggn bobbleheads..

again, me, jc, wants to see the raw data. The data that says what was actually captured by the thermometers. I also would like to know if the thermometers collect at the one thousandth or hundredth data point.

But JC, that is only because you are an idiot who doesn't know the first thing about scientific databases.

well the idiot that I am, wants to see the evidence. you know, the raw data that says the globe is warming. Not someone's mathematical readjustment done to happy out a model.

Then I suggest you get off your rump and either subscribe to a relevant peer reviewed publication, or if you are too cheap or poor, go to the friggin library.

No, I want the assholes who make claims To actually prove them. So I'm still waiting. And currently proclaim there is no warming in 18 years because assholes can't accurately prove differently. Kapeesh

Have fun at the library

In other words, you are too lazy to do anything resembling research yourself. You're like a child who wants what he wants when he wants it and doesn't want to work for it himself. Oh dear.

Why do I need to? I'm not making any claims and I call bullshit on yours . So burden of proof is on you. Sorry bubba

Actually, you have made many wild claims that you have not supported, and continue to do so. Climate change science is accepted science. So I have no burden to prove anything. That's the way it works, bubba, and when you aren't a scientist, and understand nothing about the science, you either support your claims by educating yourself and then posting refutations, or you sit at the kiddy table with all the other denier losers. It's up to you.

Doesn't matter who I am, facts remain there is zippolla evidence to any of what you claim. I'll say again the burden of proof has failed continues to fall and will continue to fail. Sorry bubba

Prove me wrong. Hahahaha

By the way, I claim nothing other than liars are liars and I have a forum of facts for my proof

The Geological Society of America - Position Statement on Climate Change

Rationale
Scientific advances in the first decade of the 21st century have greatly reduced previous uncertainties about the amplitude and causes of recent global warming. Ground-station measurements have shown a warming trend of ~0.8 °C since the mid-1800s, a trend consistent with (1) retreat of northern hemisphere snow and Arctic sea ice in the last 40 years; (2) greater heat storage in the ocean over the last 50 years; (3) retreat of most mountain glaciers since 1850; (4) an ongoing rise of global sea level for more than a century; and (5) proxy reconstructions of temperature change over past centuries from archives including ice cores, tree rings, lake sediments, boreholes, cave deposits and corals. Both instrumental records and proxy indices from geologic sources show that global mean surface temperature was higher during the last few decades of the 20th century and the first decade of the 21st than during any comparable period during the preceding four centuries (National Research Council, 2006).

Measurements from satellites, which began in 1979, initially did not show a warming trend, but later studies (Mears and Wentz, 2005; Santer et al., 2008) found that the satellite data had not been fully adjusted for losses of satellite elevation through time, differences in time of arrival over a given location, and removal of higher-elevation effects on the lower tropospheric signal. With these factors taken into account, the satellite data are now in basic agreement with ground-station data and confirm a warming trend since 1979. In a related study, Sherwood et al. (2005) found problems with corrections of tropical daytime radiosonde measurements and largely resolved a previous discrepancy with ground-station trends. With instrumental discrepancies having been resolved, recent warming of Earth’s surface is now consistently supported by a wide range of measurements and proxies and is no longer open to serious challenge.

The geologic record contains unequivocal evidence of former climate change, including periods of greater warmth with limited polar ice, and colder intervals with more widespread glaciation. These and other changes were accompanied by major shifts in species and ecosystems. Paleoclimatic research has demonstrated that these major changes in climate and biota are associated with significant changes in climate forcing such as continental positions and topography, patterns of ocean circulation, the greenhouse gas composition of the atmosphere, and the distribution and amount of solar energy at the top of the atmosphere caused by changes in Earth's orbit and the evolution of the sun as a main sequence star. Cyclic changes in ice volume during glacial periods over the last three million years have been correlated to orbital cycles and changes in greenhouse gas concentrations, but may also reflect internal responses generated by large ice sheets. This rich history of Earth's climate has been used as one of several key sources of information for assessing the predictive capabilities of modern climate models. The testing of increasingly sophisticated climate models by comparison to geologic proxies is continuing, leading to refinement of hypotheses and improved understanding of the drivers of past and current climate change.

Human‐Induced Climate Change Requires Urgent Action

Humanity is the major influence on the global climate change observed over the past 50 years.

Rapid societal responses can significantly lessen negative outcomes. Human activities are changing Earth’s climate. At the global level, atmospheric concentrations of carbon dioxide and other heat‐trapping greenhouse gases have increased sharply since the Industrial Revolution. Fossil fuel burning dominates this increase. Human‐caused increases in greenhouse gases are responsible for most of the observed global average surface warming of roughly 0.8°C (1.5°F) over the past 140 years. Because natural processes cannot quickly remove some of these gases (notably carbon dioxide) from the atmosphere, our past, present, and future emissions will influence the climate system for millennia.

Extensive, independent observations confirm the reality of global warming. These observations show large‐scale increases in air and sea temperatures, sea level, and atmospheric water vapor; they document decreases in the extent of mountain glaciers, snow cover, permafrost, and Arctic sea ice. These changes are broadly consistent with long‐ understood physics and predictions of how the climate system is expected to respond to human‐caused increases in greenhouse gases. The changes are inconsistent with explanations of climate change that rely on known natural influences.

Climate models predict that global temperatures will continue to rise, with the amount of warming primarily determined by the level of emissions. Higher emissions of greenhouse gases will lead to larger warming, and greater risks to society and ecosystems. Some additional warming is unavoidable due to past emissions.

From Britain;

https://www.geolsoc.org.uk/~/media/...Change Statement final new format.pdf?la=en

The Council of the Society is issuing this statement as part of the Society’s work “to promote all forms of education, awareness and understanding of the Earth and their practical applications for the benefit of the public globally”. The statement is intended for non-specialists and Fellows of the Society. It is based on analysis of geological evidence, and not on analysis of recent temperature or satellite data, or climate model projections. It contains references to support key statements, indicated by superscript numbers, and a reading list for those who wish to explore the subject further.

What are the grounds for concern?

The last century has seen a rapidly growing global population and much more intensive use of resources, leading to greatly increased emissions of gases, such as carbon dioxide and methane, from the burning of fossil fuels (oil, gas and coal), and from agriculture, cement production and deforestation. Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall2 ; increased acidity of the oceans 3,4,5,6; and decreased oxygen levels in seawater7,8,9.

There is now widespread concern that the Earth’s climate will warm further, not only because of the lingering effects of the added carbon already in the system, but also because of further additions as human population continues to grow. Life on Earth has survived large climate changes in the past, but extinctions and major redistribution of species have been associated with many of them. When the human population was small and nomadic, a rise in sea level of a few metres would have had very little effect on Homo sapiens. With the current and growing global population, much of which is concentrated in coastal cities, such a rise in sea level would have a drastic effect on our complex society, especially if the climate were to change as suddenly as it has at times in the past. Equally, it seems likely that as warming continues some areas may experience less precipitation leading to drought. With both rising seas and increasing drought, pressure for human migration could result on a large scale.

The vast majority of those engaged in earth sciences consider the threat of continued increases in GHGs in the atmosphere will create huge problems for us and our descendents.

Wow, 0.8 degrees in the last 150 years. I'm surprised that such a rapid warming, unprecedented is the way I've heard it described recently, hasn't already killed us all.

Basically it's been warming since the ice ages that's what that statedWho didn't know that?

Not at all. It has been in a cooling trend since the highs of about 6000 to 8000 years ago. You supply a link for your statement, and I will supply multiple links for mine.
