Is global warming happening? Topic: Nasa research on climate change
June 24, 2019 / By Bobby
Question: I'm curious to hear both sides. I hear some people saying the idea is ridiculous and its just an excuse to take peoples money... and then I've heard its true... even watched videos about it in ap bio 2 years ago... is it a theory? I know what it is... but will somebody elaborate on how we know its true/isn't

Reliable scientific sources say yes. Oil industry funded think tanks, fox news, online blogs by weathermen and economists say maybe or no. Scientific data include: - satellite measurements of the temperature http://en.wikipedia.org/wiki/Satellite_t... - satellite measurements of heat flow into/out of Earth - weather balloons - thermometers http://data.giss.nasa.gov/gistemp/ - bathythermographs and ocean buoys - boreholes http://www.ldeo.columbia.edu/edu/dees/V1... - measurements of snow extent and arrival times - movement of plants and animals towards the poles/higher elevations - increased atmospheric water vapour - an expanding troposphere (the lower atmosphere is warming, so it expands) - rising sea levels http://sealevel.colorado.edu/ - trillions of tons of ice melting since 2000 in the Arctic, Greenland and Antarctica measured by submarines, glacier velocity measurements, altimeters and gravity field satellites. - shrinking glaciers - changing seasonal arrival times All of the above support global warming occurring. Much of the data is summarised here: http://www.ipcc.ch/publications_and_data/ar4/wg1/en/contents.html Nice summary from NOAA here: http://www.ncdc.noaa.gov/indicators/ All of the above data are available on the internet from research institutions, and all of them have been confirmed by peer reviewed science in the scientific literature. If you need help finding any of the data, feel free to email me: I work in a climate research department so I know people who're able to point you in the right direction.

Acton Originally Answered: Will global warming result in larger boreal forests and help counteract global warming?
No because unfreezing the permafrost will release large quantities of methane which was previously stored in such soils. Therefore, instead of having hopes it will solve the problem, it rather looks like the problem will grow exponentially in this area.

The average temperature of Earth varies about 6-8 degrees in cycles of about 100K years. When it is 6 degrees colder than it is now, ice caps cover to about 45 degrees latitude (Chicago, Paris, Saporo, Sydney). The last ice age ended about 12K years ago. Okay, so now we are in what's called an intergalacial, the warming part of the cycle. We had a cold spell two centuries ago, but have warmed since then with only slight delays in the warming related to volcanic eruptions (1890s and 1990s) and solar variation (1970s). It's been warmer on Earth in past intergalacials by about two degrees. There was a warming period from 1920 to 1940 that resembles the warming period from 1980 to 2000, so it is ludicrous to attribute the warming to the same factor, which is what Global Warming believers have deduced through their superior minds. "What else could it be???" is the extent of their logic. So the answer is: No, Global Warming is not happening. It gets warmer, then it gets colder. The slight addition of the level of carbon dioxide that the Global Warming people want you to believe is noxious and dangerous is actually good for crops and trees, and will probably only soften the coming ice age a little...very little (about 0.2 degree).

Are you aware that global warming 'Reporters' was recently caught out that they publish inaccurate, cooked, exaggerating data ? Did you know that Carbon Dioxide sink away into solution inside the world's oceans and become removed as such ? CO2 and 'global warming is of minor effect and only a single symptom and there is still less than 0.04% in the air. What one should be really concerned about, is the incredible shortage of the Oxygen Making Species suppose to make Oxygen from the CO2 before it hijack the used-to-be breathable Oxygen down into the oceans. There is also the stealth Hydrogen Footprint that's walked hand in hand with the Carbon Footprint in STEALTH. This represent the NEW WATER we ALSO make from out of Oxygen when burning fossil fuels and biomass. Did you know that MORE than a Liter of BRAND NEW WATER is created for each Liter of Petrol, gasoline, Diesel Fuel, and so forth, that is burned ? From out of breathable Oxygen. Same like Carbon Dioxide - also from out of breathable Oxygen. This consumed/eliminated Oxygen was never replaced since the 1950's when the fossil fuel combustion rate surpassed the capability of global photo synthesis like a rabbit a snail. The ongoing removal of Stock Oxygen from the atmosphere is labeled as NEGLIGIBLE. This is so despite of the following facts : 1. The Ozone in the Ozone Layer is produced from Oxygen. 2. The space (hot) atomic Oxygen plasma Sphere above the Nitrogen atmosphere, serve a purpose of reflecting and absorbing radiation energy which it rid safely on the night side. Dilution of this extremely delicate and sensitive process in the upper atmosphere, will claim pay back. This space atomic Oxygen Layer where Oxygen presence dominate by up to 90%, compared to the Ozone Layer, is something like comparing an automatic machine gun to a single action shotgun ... 3. Oxygen is our only available Umbrella against that nuclear reactor we named "Sun". I have succeeded to prove by simple chemistry that more than a meter high of pure Oxygen (not air but Oxygen in the air) covering the globe, at sea level pressure, was completely removed from the atmosphere just from 1980 to 2006. How much was removed from the 1950's to 1980 ? How much was removed from 2006 to 2010 ? How much more will be allowed to be removed ? And if this is really negligible, how do those cackle scientists intend to put back in place, much more than 535 000 cubic kilometers of O2 at standard pressure ? And all this was done by only the combustion of the three main fossil fuels. No other fires were included here ... Watch for intensified radiation, melting the ice of the mountains from their tops.

Yes, global warming is real and has been happening since life began, and probably before. It is caused by greenhouse gases like CO2 (carbon dioxide) that create something that is kind of like a blanket in our atmosphere. Really, if you are talking scientifically about theories (generally accepted by the scientific community), then it is a theory. There is a difference between global warming and climate change though. Climate change is also a theory, and it is the reason that they decided to use for some of the mass extinctions in earth's history. With the weather patterns that are happening right now, it is actually sensible to believe that the climate is changing, but not at the rate that most people are saying it is happening (they are the alarmists), but there is no doubt that it is happening.

There are no natural causes that will explain the current relatively rapid warming trend of average temperatures on the earth. The earth hasn't suddenly gotten closer to the sun or changed its orbit or tilt. The sun hasn't suddenly gotten hotter. There is no increase in solar energy hitting the earth. All of those possible explanations for warming have been measured, and they have come up short. In fact there are no "natural" causes that account for the current warming trend. Thousands of scientists, and virtually every scientific organization that has considered the issue have concluded that the warming trend is caused by the green house effect resulting from an increased concentration of CO2 in the atmosphere which is man-caused. For example: The Royal Society (British) http://royalsociety.org/climate-change-s... The American Physical Society http://www.aps.org/policy/statements/07_... And the Geological Society of London http://www.geolsoc.org.uk/webdav/site/GS... From Science Magazine http://www.sciencemag.org/content/326/5960/1646.full And check out the articles in Scientific American Magazine. http://www.scientificamerican.com/climate Or National Geographic Magazine http://ngm.nationalgeographic.com/climateconnections Some politicians, political blogs and some popular tabloid newspapers say otherwise. You can choose who to trust.

Laurencia Originally Answered: Why do Global Warming Alarmists claim that tsunamis are caused by Global Warming?
@ Cake Good, Jeff M and Pegminer: to answer your questions - The Wall Street Journal records the shameless way in which Friends of the Earth and Greenpeace linked the devestating Asian tsunami with global warming THE DAY AFTER the tsunami struck. QUOTE - ------------------------------- "One might think that a disaster of this scale would transcend normal national or political considerations. But in the world of environmental zealotry, even an event such as this is seen as an opportunity to press the agenda. Thus, the source of the South Asian tsunami is being located in global warming. In an interview with the Independent newspaper in Britain, Stephen Tindale, executive director of Greenpeace UK, said: "No one can ignore the relentless increase in extreme weather events and so-called natural disasters, which in reality are no more natural than a plastic Christmas tree." Speaking to the same newspaper, Friends of the Earth Director Tony Juniper pressed the argument home: "Here again are yet more events in the real world that are consistent with climate change predictions." --------------------------------------... Well, it was too good a fund-raising opportunity to miss, wasn't it? Source:http://www.opinionjournal.com/editorial/feature.html?id=110006079 .
