Results for - NASA Determines Climate Change Not Due to Human Activity

1. For more than 60 years, the National Aeronautics and Space Administration (NASA) has known that the changes occurring to planetary weather patterns are completely natural and normal. But the space agency has remained largely silent amid the political debates over climate change being caused by man-made or natural phenomena. Do you think it was a responsibility of NASA to put a stop to the rumors and climate change agenda if they had evidence that said otherwise from what was being communicated to the public?
2. It was the year 1958, to be precise, when NASA first observed that changes in the solar orbit of the earth, along with alterations to the earth's axial tilt, are both responsible for what climate scientists today have dubbed as "warming" (or "cooling," depending on their agenda). Humans are in no way warming or cooling the planet by driving SUVs or eating beef. Does it surprise you that it has been known since 1958 that warming and cooling cycles of the earth are normal and largely uninfluenced by human activity?
3. In the year 2000, NASA did publish information on its Earth Observatory website about the Milankovitch Climate Theory (feel free to look it up yourself), revealing that the planet is, in fact, changing due to extraneous factors that have absolutely nothing to do with human activity. But, again, this information has yet to go mainstream, some 19 years later, which is why some climate-change alarmists have now begun to claim that we really only have 18 months left before the planet dies from an excess of carbon dioxide (CO2). Have you heard the claim that we only have 18 months to save our planet from extinction (it used to be 12 years, but now it's much less)?
4. The truth, however, is much more along the lines of what Serbian astrophysicist Milutin Milankovitch, after whom the Milankovitch Climate Theory is named, proposed about how the seasonal and latitudinal variations of solar radiation that hit the earth in different ways, and at different times, have the greatest impact on earth's changing climate patterns. These two images show how the earth's path around the sun varies - totally independent of man's activities on the planet. In the one, at zero orbit, the earth is the same distance from the sun at any point in time. The other shows the earth much closer to the sun at its perihelion (the top), which is 5km closer than it is at aphelion (the lower part of the image). Does this naturally occurring variation in orbital patterns of the earth help explain warming and cooling patterns - that has nothing to do with man's activities?
5. As for earth's obliquity, or its change in axial tilt, the above images (Robert Simmon, NASA GSFC) show the degree to which the earth can shift on both its axis and its rotational orientation. At the higher tilts, earth's seasons become much more extreme, while at lower tilts they become much more mild. A similar situation exists for earth's rotational axis, which depending on which hemisphere is pointed at the sun during perihelion, can greatly impact the seasonal extremes between the two hemispheres. Do these facts make sense of how global temperature changes are naturally occurring and can't be influenced by human activities?
6. Based on these different variables, Milankovitch was able to come up with a comprehensive mathematical model that is able to compute surface temperatures on earth going way back in time, and the conclusion is simple: Earth's climate has always been changing, and is in a constant state of flux due to no fault of our own as human beings. When Milankovitch first put forward his model, it went ignored for nearly half a century. Then, in 1976, a study published in the journal Science confirmed that Milankovitch's theory is, in fact, accurate, and that it does correspond to various periods of climate change that have occurred throughout history. Of course, this information is ignored and denied by climate change alarmists. Does it concern you that scientific facts and discoveries are sometimes hidden or squelched for political purposes?
7. Based on this information, does it make sense that no matter how much money is paid to certain politicians or their causes, there is very little that we can do, as Earth's inhabitants, that can cause any major impact on global warming or cooling cycles?
