First of all, I'm not responding to any "link." I'm responding to the silly statement that "NASA supports climate change" as if a naturally occurring planetary events are affected by whether not some scientists support the reality of their existence or not. It's like saying, "NASA supports ocean tides."
An argument worthy of a disingenuous lawyer. "Climate change" includes the period of rapid global warming/cooling that we now find ourselves in.

Where would I get proof? Do you understand what it takes to do this kind of scientific research? This is why people rely upon scientific consensus. If you want to know what that consensus is, read the link.

Oh, I get it. You equate scientific theory with guessing. Don't know much about science, do you. Oh well, feel free to educate yourself if you want to, although I'm guessing you don't want to. Very sad.
You left off the most important goal of the AGW alarmists; wealth redistribution.
I forgot about that one, how it's all the fault of developed countries, and how we owe tithing to every 3rd world craphole to ease the minds of guilt-bearing liberals.
Nice cherry picked article that plays along with the OP's story, yet real research tells a different story.
and yet NOT ONE scientist has proven MANMADE global warming
the globe evolves..the global enviroment changes..periodicly...there have been WARMER TIMES..there have been cooler times..there have been times when C02 was MUCH, MUCH higher
science shows that humans use oxygen and expele (exhale) co2
science shows that greenery (plantlife) uses co2 and expeles o2
science shows that co2 levels have been 3 times HIGHER than they are today, in the past (ie the co2 325 of today is is much lower than the 750-10000 that co2 levels were 100,000 years ago
science shows us that the earth has warmed AND cooled many times
science shows us that ANTARTICA was once a lush furtile land, not covered in ice
science shows us that greenland was once a green lush furtile land, not covered with ice
science shows us that GLACIERS created many of the geographical features that we look at today (ie Long Island was made by the lower reaching of graciers, the great lakes were created by glaciers, the grand canyon was created by glacial melting)
science shows us that plants would grow much better, and use less water if the co2 was HIGHER...around 700-1500ppm compared to the current 320ppm
The typical outdoor air we breathe contains 0.03 - 0.045% (300 - 450 ppm) CO2. Research (SCIENCE) demonstrates that optimum growth and production for most plants occur between 1200 - 1500 ppm CO2. These optimum CO2 levels can boost plant metabolism, growth and yield by 25 - 60%.Plants under effective CO2 enrichment and management display thicker, lush green leaves, an abundance of fragrant fruit and flowers, and stronger, more vigorous roots. CO2 enriched plants grow rapidly and must also be supplied with the other five "essential elements" to ensure proper development and a plentiful harvest.
science shows As CO2 is a critical component of growth, plants in environments with inadequate CO2 levels - below 225 ppm - will cease to grow or produce.
SCIENCE shows that plants exposed to elevated CO2 concentrations are likely to lose less water via transpiration
common sense states that as the earths polulation expands, so does the need for more plantlife...to keep our oxygen levels up.............yet the global warming liberals only want to talk about car/industry exaust; man created co2,.... and how to tax it
why do liberals DENY science???...because with the science they cant get their TAX..so they manipulate the science
"Climate change" includes the period of rapid global warming/cooling that we now find ourselves in.
.
historical record tells us of many warming episodes - and subsequent cooling periods - that have bedevilled humans for thousands of years.
The ancient Greek philosopher Plato, who lived in 427-347 BC, wrote about major climate changes known in his day. In the dialogue, "Timaeus," he argued global warming occurs at regular intervals, often leading to great floods. Said Plato, "When... the gods purge the Earth with a deluge of water, the survivors... are herdsmen and shepherds who dwell on the mountains. But those who... live in cities are carried by the rivers into the sea."
In the dialogue, "Critias," Plato wrote about weather-related geological changes. He referred to "formidable deluges" that washed away all the top soil, turning the land into a "skeleton of a body wasted by disease." What were now plains had once been covered with rich soil, Plato said, and barren mountains were once covered with trees. The yearly "water from Zeus" had been lost, he went on, creating deserts where the land was once productive.
Plato's student, Aristotle, who lived from 384 BC to 322 BC, also recorded evidence of global warming in his work, "Meteorologica." He noted that in the time of the Trojan War, the land of Argos was marshy and unarable, while that of Mycenae was temperate and fertile. "But now the opposite is the case," Aristotle wrote. "The land of Mycenae has become completely dry and barren, while the Argive land that was formerly barren, owing to the water has now become fruitful." He observed the same phenomenon elsewhere covering large regions and nations.
Theophrastus, a student of Aristotle who lived 374-287 BC, discussed climate change in his work, "De ventis," which means "The Wind." He observed that in Crete, "nowadays the winters are more severe and more snow falls." In earlier times, he said, the mountains there bore grain and fruit, and the island was more populous. But when the climate changed, the land became infertile. In his book, "De causis plantarum," Theophrastus noted the Greek city of Larissa once had plentiful olive trees but that falling temperatures killed them all.
In the first century AD, an ancient Roman named Columella wrote an agricultural treatise called, "De re rustica." In it, he discussed global warming that had turned areas once too cold for agriculture into thriving farm communities. Columella cites an authority named Saserna who recorded many such cases. According to Saserna, "regions which formerly, because of the unremitting severity of winter, could not safeguard any shoot of the vine or the olive planted in them, now that the earlier coldness has abated and weather is becoming more clement, produce olive harvests and the vintages of Bacchus [wine] in greatest abundance."
In the Middle Ages, people began recording the temperature and climate-related phenomena, such as the dates when plants began to blossom annually. They were aware of a warming trend that began around 900 and a cooling trend that began around 1300. We know that during the warm period, the Vikings established settlements in Greenland where perpetual ice had previously covered the land. Ancient Norse records tell us these settlements were abandoned after 1250 when falling temperatures made farming less viable and spreading ice in the sea made transportation more difficult.
The cooling trend led to heavy rains in 14th century Europe that were too much for the crops, leading to reduced agricultural output and numerous famines. In the 15th century, a warming trend returned, which lasted until the middle of the 16th century when temperatures again started to fall. By the 17th century, it was clearly apparent that a cooling trend was altering sea routes, changing the kinds of crops farmers could grow, fishing patterns and so on. Glaciers began to advance rapidly in many places and rivers that had long been ice-free year round started to freeze in the winter. This "little ice age" continued well into the 19th century.
Since then, we have been in a warming cycle that appears to have accelerated around 1950. The point is that we know a great deal about climate changes from the historical record and need not rely solely on scientific studies of core samples, tree rings and so on. These changes occurred long before industrialization and could not possibly have been man-made in any way. They don't prove man is not now affecting the climate through carbon dioxide emissions, but they do tell us temporary warming trends are common in human history. It may only be a matter of time before another cooling trend comes along.
you see the problem,,we are not saying that there is no such thing as global warming/cooling...we are saying that it is a NATURAL OCCURANCE.....The simple FACT is, to say its 'man-made' is just a LIE...do we humans help/hinder it...certainly..but we are not the CAUSE
You know in reality, humanity had better start thinking about cooling because regardless of what we want or believe, the natural state of the planet for the last few million years has been Ice Age....
If we dont figure out how to either live with a much colder world, or to mitigate it, in a few hundred years or so, its gonna get bad...
Exactly.
Researchers have some interesting observations on that. They've found that human impact of the last 8,000 years is forestalling what would be a normally occurring impending ice age.
Quote:
We're at a very favorable state right now for increased glaciation," says Kutzbach. "Nature is favoring it at this time in orbital cycles, and if humans weren't in the picture it would probably be happening today."
Using three different climate models and removing the amount of greenhouse gases humans have injected into the atmosphere during the past 5,000 to 8,000 years, Vavrus and Kutzbach observed more permanent snow and ice cover in regions of Canada, Siberia, Greenland and the Rocky Mountains, all known to be seed regions for glaciers from previous ice ages. Vavrus notes: "With every feedback we've included, it seems to support the hypothesis (of a forestalled ice age) even more. We keep getting the same answer.
What's scary is how easy it has been for the AGW (Anthropogenic Global Warming) cultists to emotionally manipulate some of the general public. Reminds me of the Flat-Earthers in the not too distant past.

Indeed.
The global warming crowd is a cult worship based on everything BUT science. The ironic thing is that those believing in global warming actually believe that their presumptions are backed by valid science, when in fact the opposite is true.
I fully support scientific endeavors and the conclusions drawn by VALID SCIENCE. Global warming is as far from valid science as one can get. It was simply a hoax, perpetuated for political goals, which many, many people were duped into believing.
What's wrong with you? How come people like you won't read links from reputable sources?
How could any source possibly be reputable, when the source doesn't even understand the meaning of "Inter-Glacial Period?"

And how do they know this? Hey, research technology has improved!
I'm certain technology has improved, but reading comprehension has not.
Let's review....

There have been more than that, but who's counting? This is Normal Earth...
Why? Because 24 Million Years Ago, ocean currents flowed north around the South American continent, but thanks to Plate Tectonics, two plates collided creating the Panamanian Isthmus, blocking the flow of ocean currents in the southern Atlantic/Pacific.
At that time, the Atlantic Ocean was 1/3 smaller than it is now, and much warmer in temperature.
As the Mid-Atlantic Ridge pushed all the North/South American plates west, the Atlantic Ocean expanded and size, and became colder in temperature, as ocean currents in the Atlantic/Pacific now circulated separately.
That led to a cooling of global temperatures, creating Normal Earth and periods of Ice Ages.

That statement is patently false.
The Ice Age was coming to a natural Inter-Glacial Period, but a cataclysmic event occurring 12,000 years ago brought the Inter-Glacial Period on more rapidly.
That cataclysmic event consisted of numerous global impacts of an asteroid, an asteroid/meteor swarm, or possibly a comet, which had broken up due to gravitational forces, and then broke apart further colliding with Earth's atmosphere. We can see the impacts here....
Those small impact craters range up and down the US Eastern Seaboard. Many more impacts occurred on the Continental Shelf, which is now under sea-level. All evidence to date suggests that this event...
1] is responsible for the annihilation of the Clovis People; and
2] the extinction of large mammals such as Mastodons, Mammoths, Giant Bears, Giant Sloths and Sabre-Toothed Cats; and
3] numerous geological anomalies across North America; and
4] the total destruction of the Western Ice Sheet in Antarctica; and
5] the tsunamis created in some of the world's oceans/seas may be the basis for the pervasive "flood myths"
So....the destruction of the Western Ice Sheet, plus the melting glaciers caused the sea levels to rise, which also resulted in a change of climate. What was once a lush tropical paradise is now the Sahara, the barren Sinai Peninsula and the near barren Arabian Peninsula.
7,000 years ago? That would be 5,000 BCE......and that is lie, and then you ask a silly question like why doesn't anyone read reputable sources.....the [very] obvious answer is that so-called "reputable" sources have an agenda and they lie.
What was around 7,000 years ago? Sumer.
The little city-states that made up Sumer caused the end of the last Ice Age?
Are you for real?
