Is Climate Change real or a Hoax

[metis]

The reality is, CO2 and the other greenhouse gases, can also block the heat from the sun, so less reaches the surface.

I understand what causes global warming. The sun's rays travel through the atmosphere, hit earth and than bounce back into space. But because of green house gases, not all of the heat bounces back into space, and this makes earth hotter. Why don't greenhouse gases also block out some of the incoming rays from the sun, and counteract global warming?

Answer:
Greenhouse gases are transparent to the wavelengths of the incoming radiation.

Explanation:
Everything reacts differently to energy at different wavelengths. This is way xrays (very short wave lengths) can travel through your skin while light (short wave lengths but much longer than x-rays) is blocked by your skin.

Incoming solar radiation (visible spectrum for the majority) that heats the Earth is about 1/10th the wavelength of outgoing radiation (infrared or heat). For a gas like carbon dioxide this means that in coming radiation is like an x-ray, traveling cleanly through it, but the out going radiation hits it like a wall, trapping the heat. -- Why don't greenhouse gases also block out some of the incoming rays from the sun, and counteract global warming? | Socratic

One minor correction. Light reflected by the surface is of the same wavelength and escapes. It is the light that is absorbed and reemitted that is trapped. Absorbed visible light turns into heat and is reemitted as infrared. That light is trapped by the Greenhouse Effect.

Nope, you do not understand how the Greenhouse effect works. It is not that hard to understand, would you like to go over it?

I would very much like for you to tell me how the greenhouse effect works-?
Thanks in advance
(this is not a trap question; I truly want to know-)

Climate change is certainly not a hoax.

The narrative that it "may be" a hoax or a politically charged idea, however, is definitely a hoax. A very tragic one.

Glad to. It would first help to get familiar with the Stefan Boltzmann Law. No need to understand it's derivation, just that it is a laboratory tested and confirmed law that allows us to predict the temperature of a body if we know how much energy it is exposed to. If you are curious about it Wiki has a nice article about it:

Stefan–Boltzmann law - Wikipedia

As I said scientists can directly measure how much energy from the Sun is hitting the Earth every second. And the Stefan Boltzmann Law allows us to calculate what the average temperature of the Earth would be using that law. If the Earth was a perfect black body the average temperature should be 5.3 C or 41.5 F. But wait the Earth is not a perfect black body. Some of the energy from the Sun is reflected by the clouds. Some is reflected from the land and the seas and the icecaps are very reflective. That means it should be even colder or about 0 F or -18 C. Clearly something is not quite right. This was known in the first half of the 19th century. Something else is clearly a factor.

And that factor are what are known as greenhouse gases. They are transparent to visible light, but absorb infrared. So what happens is that the light that makes it through the Earth's atmosphere and is absorbed will eventually be reradiated. But as you well know the warm ground does not radiate in the visible spectrum. It reradiates in the infrared. And that is the key. That light is absorbed on its way out It does not escape directly back to space. After it is absorbed it too is released again. Some of it will go out to space. some of it will go back down to the Earth and the light that goes back down warms the Earth again. It adds heat to the Earth. Eventually it will radiate out, but CO2, water vapor and methane and others will slow down the process. Just as a blanket slows down your loss of body energy the blanket of greenhouse gases keeps the Earth from losing energy from the Sun as fast as it normally would.

We clearly need some greenhouse gases, but just like so many other things that we need there is a happy medium.

It has been explained here by several of us, so I don't know what else to add.

Scientists have known about the "greenhouse effect" since the 1800's, well knowing what higher levels of CO2 and methane gas can do through their laboratory experiments. Maybe look it up at Wiki for further information and links to some of the studies done on this. .

Ignorance is not a virtue

An ice age is a period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed "glacial periods" (or alternatively "glacials" or "glaciations" or colloquially as "ice age"), and intermittent warm periods are called "interglacials". In the terminology of glaciology, ice age implies the presence of extensive ice sheets in both northern and southern hemispheres.[1] By this definition, we are in an interglacial period—the Holocene—of the ice age. The ice age began 2.6 million years ago at the start of the Pleistocene epoch, because the Greenland, Arctic, and Antarctic ice sheets still exist.[2]

"Potentially historic" flooding threatens Southern states
Scientists are warning that historic flooding could soon deluge parts of several Southern states along the lower Mississippi River, where floodwaters could persist for several weeks. The flood threat in the South will be discussed Thursday, when the National Oceanic and Atmospheric Administration releases its 2019 spring outlook.

Experts plan a briefing on their flood forecast at the National Water Center in Tuscaloosa, Alabama. Thursday's report is aimed at helping emergency managers and other safety officials to prepare for flooding.

Flooding in Southern states this spring will be "potentially historic," NOAA said in an advisory.

Historic Midwest Flooding Likely to Cost at Least $1.3 Billion in Nebraska Alone; Missouri Towns Ordered to Evacuate
https://weather.com/news/news/2019-03-18-flooding-midwest-nebraska-iowa-rivers

A study by NASA and university researchers, published in the June 14, 2013 issue of Science, found however that ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss.[2]
https://en.wikipedia.org/wiki/Ice_shelf

An ice shelf is a thick suspended platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is called the grounding line. The thickness of ice shelves can range from about 100 m (330 ft) to 1,000 m (3,300 ft).

The Snowball Earth hypothesis proposes that during one or more of Earth's icehouse climates, Earth's surface became entirely or nearly entirely frozen at least once, sometime earlier than 650 Mya(million years ago). Proponents of the hypothesis argue that it best explains sedimentary deposits generally regarded as of glacial origin at tropical palaeolatitudes and other enigmatic features in the geological record. Opponents of the hypothesis contest the implications of the geological evidence for global glaciation and the geophysical feasibility of an ice- or slush-covered ocean[3][4]

In the beginning, planet Earth was a very inhospitable place with no oxygen and only single-celled bacteria as inhabitants. According to a new study, the oxygen content in the air began to increase about 2.4 billion years ago, at the same time as the global glaciation and when all continents were gathered in a single huge landmass, or supercontinent. How to explain the exact connection between these events, however, is a question that baffles the researchers.

A Brief History of Ice Ages and Warming
Global warming started long before the "Industrial Revolution" and the invention of the internal combustion engine. Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.

I did--
Animals breath in O2 and exhale CO2
Plants breath in CO2 and exhale O2

Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms.

CO2 is produced by all aerobic organisms when they metabolize carbohydrates and lipids to produce energy by respiration.[7]

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water– hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις, synthesis, "putting together".[1][2][3] In most cases, oxygen is also released as a waste product.

Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs.

No. It only contributes a small amount of heat. Not nearly enough to account for the temperature above what the Stefan Boltzmann Law predicts. For example the total energy leaving the Earth a year is:

" The total heat flow for the planet is 47 TW +/- 2TW, which is equivalent to 0.09Wm-2 (90mWm-2)."

https://skepticalscience.com/heatflow.html

Where the incoming solar radiation is 341 W/m^2. Or in other words the heat from the Earth itself s roughly one three thousandth of the heat from the sun.
