Climate Science

https://phys.org/news/2018-03-degree-global-million-people.html A half degree more global warming could flood out 5 million more people: March 9, 2018 by Liz Fuller-Wright, Princeton University The 2015 Paris climate agreement sought to stabilize global temperatures by limiting warming to "well below 2.0 degrees Celsius above pre-industrial levels," but a recent literature review found the 2 degree limitation "inadequate" and concluded that limiting global warming to no more than 1.5 degrees would "come with several advantages." To quantify what that would mean for people living in coastal areas, a group of researchers employed a global network of tide g…

I am helping my son with a high school project so I want to make sure i get this 10000% right! He has been asked to apply the formal scientific method analysis to the question of 'climate change'. I went to wiki and summarised the method to .. 1. Observe world and propose something 2. Show the Null Hypothesis does not stand 3. Propose new hypothesis 4 Produce quantitative model and falsification criteria 5 New theory holds a long as model is never falsified I must say, although it all looks so simple I am rather stuck. There seems to be a lot of vagueness in what is discussed and the model bit really baffles me. Any help apprec…

I found these links while deciding to take a look at climate change. https://www.skepticalscience.com/heading-into-new-little-ice-age-intermediate.htm https://www.skepticalscience.com/heading-into-new-little-ice-age.htm I was wondering the vadidity of what they said.

I can't help but notice that we are having a bit of a series of Atlantic storms (even one Hurricane Ophelia earlier) The thought has crossed my mind that all this stirring up of the atmosphere might lead to an increased warming of the Arctic. Anything in that?

Does anyone know what times of the year, during the equinoxes (Mar 20 & Sep 22/23) or during the solstices (Dec 21/22 & Jun 20/21), are day length changing more rapidly? My guess would be the length of day is changing most rapidly during the equinoxes, is that correct?

Notice it is the women who seem do all the work here. But seriously it is a great project. http://www.bbc.co.uk/news/av/magazine-41391844/why-is-africa-building-a-great-green-wall

Recently I heard someone state on CNN or MSNBC that climate change has not increased the frequency of severe hurricanes in the past 100 years. Nobody disputed it, which amazed me. I did a little research and found this 2012 article in Forbes. Is this true? It states: "Let’s split the 100-year hurricane record in half, starting with major hurricane strikes during the most recent 50 years. During the most recent decade, 2001-2010, 7 major hurricanes struck the United States. That is exactly the 100-year average. During the preceding decade, 1991-2000, 6 major hurricanes struck the United States. That is below the 100-year average. During the decade …

With the current rate of global warming, how long will it take for trees to be able to grow back in Antarctica?

As the title says, what were the oxygen levels during these periods? I always thought the O2 levels were higher than we have today, but I read different articles saying they were actually lower. What are everyone's thoughts on this? Also, could we breathe in these environments?

Tim Flannery talks about using 9% of the world's oceans to farm kelp to sequester 40 Gigatons of carbon emissions annually, or roughly 2ppm CO2 per year. goo.gl/n6iFdG Seaweed farming is already an established industry in many countries, but this project would be expanding it by 20,000 times. https://en.wikipedia.org/wiki/Seaweed_farming Thoughts:- * SYNGAS FROM SEAWEED TO BACKUP ALL RENEWABLES WORLDWIDE! A ton of CO2 concentrated into biomass is about a ton of wood. 40 Gigatons would 40 cubic kilometres of woody waste to dispose of each year. We already know how to biochar any dried biomass waste. 40 cubic kilometres into a biochar unit could produce maybe 20 cubi…

Does anyone know anything about the following story? It says: “...world leaders were duped into investing billions over manipulated global warming data” that has the details of yet another global warming data scandal. According to the report, fake data was made up prior to the 2015 Paris accords. The Mail on Sunday today reveals astonishing evidence that the organisation that is the world’s leading source of climate data rushed to publish a landmark paper that exaggerated global warming and was timed to influence the historic Paris Agreement on climate change. A high-level whistleblower has told this newspaper that America’s National Oceanic and Atmospheric …

Hello all, I live in Netherland, Europe. I dive a hybrid car and I have 3.2 kWp of solar panels on my roof. I do not use natural gas for heating but an air/air heatpump with a COP of 5.0. So yes, I do believe in climate change and that it is (at least partially) caused by human activity. At a party I met some one who called himself a climate skeptic, he did believe that climate change was a fact but not that it was significantly influenced by mankind. He challenged me to calculate what effect (increase in temperature) a doubling of CO2 would have on the climate. And that is what I did, or at least tried to do, a few days later. And to my surprise it was very little, m…

How can electronics be cooled, to close to freezing temps, without causing condensation?

Hey guys, This has been a really big mystery to me and my classmates for a while so we wanted to ask more experienced people on what the reasons are. ___________________________________________________________ If hot air holds more moisture than cold air does, which causes hotter areas to be more humid, like Texas and Flordia. Reference) “Warm air can hold more water than cool air.” From Scientific American 1) Then how come there are many areas where it is hot and not humid? Reference) “Dry regions, where evaporation and evapotranspiration exceed the annual mean precipitation, cover about 40% of Earth’s land surface and affect th…

Hi all. I am a junior civil engineer, my specialty is in traffic and transportation engineering. I also work on drainage, utilities, and structural (Soundwall / parking structure PS&E). I am fortunate to have a well-rounded work environment. I have always been passionate about the environment in general, and I always think about the environmental impact of my design, even though I have an expert coworker with over 30 years of experience assessing environmental impact of our designs. I live in southern California, so I think about water conservation, capture, retention, treatment, and reuse. I also think about material, although I am constrained by having to ba…

Point all wheel driven vehicles in the direction of the Sun. Then at a designated moment everyone accelerate as hard as the vehicle will, then roll to a stop. Repeat. The Earth will be moved "out" of its orbit from the Sun... all actions having an equal and opposite reaction an' all... of course, more distance = less heat. Possibly it may be more efficient to point the vehicles in the opposite direction to the Earths orbit to speed earths orbit to counter centripetal effect of the Suns gravity allowing Earth to move away from it... If you are good with arithmetic you may like to crunch the numbers vis a vis vehicles pointed at the sun versus vehicles pointed…

I was looking at Google Earth the other day and, unless there is something very wrong with it, there does not appear to be any ice north of Svalbard or Greenland. Has the entire north pole melted now? Sadly I asked the same thing of one of the teachers in the school I work at the other day. He did not know the answer but we were overheard by a very concerned 8 year old girl who immediately asked me where Santa lives now if the north pole melted.

Hi, we're having a climate discussion over on a theology site (Reasonable Faith) and I have to admit, we aren't the best at discussing climate science... We have one poster who seems to be qualified to discuss it, but he denies anthropogenic global warming. An example: http://www.reasonablefaith.org/forums/choose-your-own-topic/climate-change-what-are-actual-scientific-data-logical-arguments-6036281.msg1275589094.html#msg1275589094 Would someone be kind enough to look into the discussion and dumb down why he has a point, or, if he doesn't, why? He has said "I'd really like this discussion to be about hard science, the actual data. " But, of course, w…

I read an interesting post on why some people may be climate science skeptics. Climate science skeptics will cite record temperatures in the dust bowl and stuff, right? Well, there is something to that, but those extremes hide gradual change. This guy analyzed data for his home state (Kentucky, home of the Famous Mitch McConnel) and found some interesting trends in the data there. High temperatures are declining slightly. Low temperatures are increasing more. But these trends don't tend to set records. So all the records stand. So, yes, the climate is changing, and yes, it was hotter in the dust bowl. It's not simple. http://www.vofoundation.org/blog/swelte…

The warming started circa 1886 - long before man had the capacity to effect the climate. What's more, the heat characteristics of CO2, 0.04% atmosphere, is almost identical to O2 at 21%. If you look at the spectrum absorption of CO2 you can see that it is almost perfectly between the emission spectrum of the Sun and the radiation spectrum of the Earth. In other words it neither absorbs as much heat as O2 but it receives a great deal less to begin with. All of the charts showing the effects of O2 and CO2 have been massively out of scale. And neither gas is of much importance. Earth is a water planet. 70% of the surface of the Earth is made up of liquid water or ice…

Any climate scientists out there understand the point that a reputable Ph.D. climatologist, Roy Spencer makes to dispute the consensus view of climate change? This is from his web site. I was searching for a climate science expert that is a skeptic and Roy Spencer looks like the real thing. http://www.drroyspencer.com/global-warming-101/ "It has been calculated theoretically that, if there are no other changes in the climate system, a doubling of the atmospheric CO2 concentration would cause less than 1 deg C of surface warming (about 1 deg. F). This is NOT a controversial statement…it is well understood by climate scientists. (As of 2008, we were about 40% to 4…

So I'm new here and I don't know if this question has been asked before but I'd really like to know what possible route the world would have taken if the industrial revolution began with the discovery of solar energy as opposed to coal. What would our world look like today?

Can you speculate if hurricane Matthew turns to south east as some prediction models show, and collides with hurricane 'Nicole' in the same area ? Has such event happened before ? What would happen ?

The other night there was the freakiest lightning storm in have ever seen in the few years I've known what lightning is. A single, white cloud, on an otherwise empty night sky, with stars, started shooting lightning everywhere. Like a giant web of lightning going out from all sides. The odd part is seeing lightning outside of the cloud. Usually when you see lightning its in a cloud, but the other night there were no clouds and it was going right out of it and striking nothing. It was my belief that lightning was a large release of static electricity when something came in range to be struck. Anyway, my question is, what caused the lightning to do what it did? For half an …

How does Carbon Dioxide get trapped in the upper atmosphere if it's heavier than other particles in the atmosphere? For example if you take a canister of water and add dry ice, and bubbles start to pour out. The bubbles will sink to the ground and not float, because it's heavier than the air around it. This got me wondering how Carbon dioxide gets stuck up in the Stratosphere. Thanx!
