Do You Know What You're Talking About?: Climate Change and Global Warming

Climate change occurs when changes in Earth's climate system result in new weatherpatterns that last for at least a few decades, and maybe for millions of years. The climate system is comprised of five interacting parts, the atmosphere (air), hydrosphere (water), cryosphere (ice and permafrost), biosphere(living things), and lithosphere (earth's crust and upper mantle). The climate system receives nearly all of its energy from the sun, with a relatively tiny amount from earth's interior. The climate system also gives off energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling.

As this energy moves through Earth's climate system, it creates Earth's weather and long-term averages of weather are called "climate". Changes in the long term average are called "climate change". Such changes can be the result of "internal variability", when natural processes inherent to the various parts of the climate system alter Earth's energy budget. Examples include cyclical ocean patterns such as the well-known El Niño–Southern Oscillation and less familiar Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate change can also result from "external forcing", when events outside of the climate system's five parts nonetheless produce changes within the system. Examples include changes in solar output and volcanism.

Human activities can also change earth's climate, and are presently driving climate change through global warming.[1] There is no general agreement in scientific, media or policy documents as to the precise term to be used to refer to anthropogenic forced change; either "global warming" or "climate change" may be used.[2]

Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming.[2][3] Though earlier geological periods also experienced episodes of warming,[4] the term commonly refers to the observed and continuing increase in average air and ocean temperatures since 1900 caused mainly by emissions of greenhouse gases in the modern industrial economy.[5] In the modern context the terms global warming and climate changeare commonly used interchangeably,[6] but climate change includes both global warmingand its effects, such as changes to precipitation and impacts that differ by region.[7][8] Many of the observed changes in climate since the 1950s are unprecedented in the instrumental temperature record, and in historical and paleoclimate proxy records of climate change over thousands to millions of years.[2

The terms are often used interchangeably, however there is a clear distinction between them...

There are meaningful questions that arise in the course of discussion and debate on these topics that can easily become confused as conflation of the terminology becomes an element of the discourse...

Good info there Ron. i'm inclined to say science is my bag though for my own remaining sanity and the sake of science i'd pray it's the other way around but I have faith it's not. At any rate, acceleration due to gravity being itself a rate, a constant:

Gravity accelerates you at 9.8 meters per second per second. After one second, you're falling 9.8 m/s. After two seconds, you're falling 19.6 m/s, and so on. It's the square root because you fall faster the longer you fall.

Speed rises only as the square root of the height of the fall. By the way, you start endangering your limbs at about twenty feet per second (depending on your age and physical condition). Gravity will accelerate any object at a rate of 32 feet per second per second.

Why is the earth's core so hot? And how do scientists measure its

The magnitude of the third main source of heat--radioactive heating--is uncertain. ... We know that the earth's core depths from 2,886 kilometers to the center at ...

Earth's internal heat

The flow of heat from Earth's interior to the surface is estimated at terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth 1 Terawatt: Exactly one-million times one-million.  One times ten the twelfth power. Heat and early estimate of ... · ‎Global internal heat flow · ‎Radiogenic heat

The amount of electricity that a power plant generates during a period of time depends on the amount of time it operates at a specific capacity. For example, if the R. E. Ginna reactor operates at 582 MW capacity for 24 hours, it will generate 13,968 megawatthours (MWh).Dec 4, 2018How much electricity does a nuclear power plant generate? -

Gotta run, almost if not literally. Want to return to see how an operating nuclear plant in a year produces in terawatts.

Moki, A Question for you:

Are we causing or exacerbating climate change, or are we witnessing/experiencing some kind of overriding cyclical atmospheric climate event?

Comment by koshersalaami on May 24, 2019 at 12:50pm

Is that only a question for Moki? 

Just so you know, Current extinctions are happening at a faster rate than at any point since the Cretaceous.

Time to cut the bullshit about Climate Change! Since the beginning of time the earth's climate has been changing. Why was Earth in a cooling phase for 15 years causing the East Anglia scientists to inform their colleagues how to tweak their faulty climate models? This happened in 2011! The US has 50 individual state environmental agencies over seeing pollution! Enough is enough! The worlds oceans and volcanoes spew more carbon emissions into the air than anything human activity can dish out! NASA has admitted they fudged their satellite data, that sun spot activity is the driving force behind cyclical change in global temperature, and that global stretch is also responsible for cooling periods as well! Carbon dioxide is beneficial it feeds photosynthesis! Photosynthesis creates green plant growth who in turn use carbon dioxide to create oxygen and in exchange! Ron cut the political bullshit! Climate change is just another way that the world governments can find to control the population with taxes and restriction via Agenda 21! Wake the fuck up!

Once again, we’re seeing extinctions at a faster rate than at any time since there were dinosaurs. Normal climate cycles couldn’t do that because we don’t measure them in, I don’t know, 50 million year increments. Something is awfully unusual right now.

Not just for Moki...

However,  he seems to have a handle on enough science to provide an interesting response...

Re the extinction of dinosaurs. The planet was hit with something that caused the end of the dinosaurs and set in motion the evolutionary chain of events that led to homo sapiens...

Even a cub scout knows that you don't put out a campfire with a cup of gasoline.

Comment by koshersalaami on May 24, 2019 at 4:32pm

So if we eliminate whatever hit the planet, the last time we saw this many extinctions would go back even further, strengthening my point. 

Of course we’re causing and exacerbating climate change. 

It doesn’t take long to search for something, but here:
