Is Global Warming On The Rise or Is It Fake News?
Scientific Evidence For Warming Of The Climate Is Subjective Depending On The Source
This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution.
The Earth’s climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.
The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.
Ice cores drawn from Greenland, Antarctica, and Tropical Mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.
Sea level rise
Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century.
Global sea level change for much of the last century has generally been estimated using tide gauge measurements collated over long periods of time to give a long-term average. More recently, altimeter measurements — in combination with accurately determined satellite orbits have provided an improved measurement of global sea level change. To measure sea levels prior to instrumental measurements, scientists have dated coral reefs that grow near the surface of the ocean, coastal sediments, marine terraces, ooids in limestone’s, and near shore archaeological remains.
Global temperature rise
The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year, from January through September, with the exception of June, were the warmest on record for those respective months.
Cause and Effect Of Climate Change
On the broadest scale, the rate at which energy is received from the Sun and the rate at which it is lost to space determine the equilibrium temperature and climate of Earth. This energy is distributed around the globe by winds, ocean currents, and other mechanisms to affect the climates of different regions.
Factors that can shape climate are called climate forcings or “forcing mechanisms“. These include processes such as variations in solar radiation, variations in the Earth’s orbit, variations in the albedo or reflectivity of the continents, atmosphere, and oceans, mountain-building and continental drift and changes in greenhouse gas concentrations. There are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the climate system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings, while others respond more quickly. There are also key threshold factors which when exceeded can produce rapid change.
The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.
Shrinking ice sheets
The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.
A world glacier inventory has been compiled since the 1970s, initially based mainly on aerial photographs and maps but now relying more on satellites. This compilation tracks more than 100,000 glaciers covering a total area of approximately 240,000 km2, and preliminary estimates indicate that the remaining ice cover is around 445,000 km2. The World Glacier Monitoring Service collects data annually on glacier retreat and glacier mass balance. From this data, glaciers worldwide have been found to be shrinking significantly, with strong glacier retreats in the 1940s, stable or growing conditions during the 1920s and 1970s, and again retreating from the mid-1980s to present.
The most significant climate processes since over the past 3 million years are the glacial and interglacial cycles. The present interglacial period has lasted about 11,700 years. Shaped by orbital variations, responses such as the rise and fall of continental ice sheets and significant sea-level changes helped create the climate. Other changes, including Heinrich events, Dansgaard–Oeschger events and the Younger Dryas, however, illustrate how glacial variations may also influence climate without the orbital forcing.
Glaciers leave behind moraines that contain a wealth of material including organic matter, quartz, and potassium that may be dated, recording the periods in which a glacier advanced and retreated. Similarly, by tephrochronological techniques, the lack of glacier cover can be identified by the presence of soil or volcanic tephra horizons whose date of deposit may also be ascertained.
The number of record high temperature events has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events both nationally and ~in region~
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.11,12 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.
Decreased snow cover
Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over the past five decades and that the snow is melting earlier.
How Does Climate Change Affect You
In the context of climate variation, anthropogenic factors are human activities which affect the climate. The scientific consensus on climate change is “that climate is changing and that these changes are in large part caused by human activities,” and it “is largely irreversible.”
“Science has made enormous inroads in understanding climate change and its causes, and is beginning to help develop a strong understanding of current and potential impacts that will affect people today and in coming decades. This understanding is crucial because it allows decision makers to place climate change in the context of other large challenges facing the nation and the world. There are still some uncertainties, and there always will be in understanding a complex system like Earth’s climate.
Nevertheless, there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations.”
Of most concern in these anthropogenic factors is the increase in CO2 levels ~in region~. This is due to emissions from fossil fuel combustion, followed by aerosols (particulate matter in the atmosphere), and the CO2 released by cement manufacture. Other factors, including land use, ozone depletion, animal husbandry (ruminant animals such as cattle produce methane, as do termites), and deforestation, are also of concern in the roles they play – both separately and in conjunction with other factors in affecting climate, microclimate, and measures of climate variables.
How Good Are The Facts For Climate Change
Information and data is somewhat reliable from the USGS and NASA Science. But it’s all about the political goals behind the science and the agenda’s presented by the left and the Green Organizations. Green supporters muddy the water with pictures and erroneous reporting. Aside from that, to truly understand the problem, those living must take it upon themselves to get educated.
Clearing The Air On Climate Change Efforts
Up until now, our government has been playing cloak and dagger routines to assure American’s that the problem of Climate Change is real. The reality is that the increase in green house gases began escalating during the Industrial Revolution and has not stopped. The blame is on our use of fossil fuels and population growth. Here in lies the conundrum that the higher the population of the United States, the more CO2 is dumped into the Atmosphere. Without a heavy price to pay, i.e. higher taxes, other sources, etc., this problem will not go away. Increasing immigration will not solve the problem, it only increases the problem.
The plain truth is that the U.S. is not the chief violator and that several other European and Asian countries pour more into our atmosphere than we do. Hence the efforts behind the Paris Climate Accord as a way to solve a problem, but as a percent of contribution, the U.S. was leading the pack. Although Al Gore wants the U.S. to do more, there has to be a global effort. Until countries like China and India scale back on population growth, there will be no effort to realistically reach goals. The U.S. is basically alone in this effort and hence the reason Trump pulled out.
The Government Cover-up On Climate Change
Opponents of climate action have frequently highlighted data that seemed to suggest global temperatures stopped rising from about 1998 to the early part of the 21st century. They say it shows the Earth is constantly in cycles of cooling and heating and they dispute the notion that global temperatures are consistently rising as the result of human activity. It has become a frequent talking point for politicians who argue that there is no urgency to curb the use of fossil fuels. The battle goes on to suggest that the science quoted by Al Gore and others may be questioned.
But political chips are played to support or tear down the idea of Climate Change depending upon which side of the political fence you are on or the dollars being thrown back and forth by political constituents. In other words, the pork barrel is still in Washington.
What You See As Contrails From Commercial Airliners
There are times when you can see dozens of contrails in the sky that appear periodically on specific days of the week. This probably varies depending on your area, but noticeable if you occasionally “look up”.
Normal jet exhaust disappears within a reasonable length behind the airliner. The distance is hard to judge but they eventually fade. The ones that do not are Chemtrails and typically come from government aircraft flying above 40,000 feet. These are not contrails but chemicals spewed by nozzles located on the wings of these military aircraft and they expand and stick around for hours.
The smoke and mirrors here is the cover up of the chemical compound but it’s designed to block the sun. The presumption is that it’s a copper sulfate mixture but no information is available.
Chemtrail Controversy Continues
The chemtrail conspiracy theory is the claim that long-lasting trails, so-called “chemtrails”, are left in the sky by high-flying aircraft and that they consist of chemical or biological agents deliberately sprayed for unknown purposes undisclosed to the general public. Believers in the theory argue that normal contrails dissipate relatively quickly and that contrails that do not dissipate must contain additional substances. These arguments have been dismissed by the scientific community: such trails are normal water-based contrails (condensation trails) that are routinely left by high-flying aircraft under certain atmospheric conditions. Although proponents have attempted to prove that the claimed chemical spraying does take place, their analyses have been flawed or based on misconceptions.
Because of the persistence of the conspiracy theory and questions about government involvement, scientists and government agencies around the world have repeatedly explained that supposed Chemtrails are in fact normal contrails.
The term chemtrail is blending of the words chemical and trail, as contrail is of condensation and trail.
Believers in the conspiracy theory speculate that the purpose of the claimed chemical release may be solar radiation management, psychological manipulation, human population control, weather modification, or biological or chemical warfare and that the trails are causing respiratory illnesses and other health problems.
In 2007, a Louisiana television station report claimed evidence for Chemtrails. In the report the air underneath a crosshatch of supposed Chemtrails was measured and apparently found to contain unsafe levels of barium: at 6.8 parts per million, three times the US nationally recommended limit. A subsequent analysis of the footage showed, however, that the equipment had been misused, and the reading exaggerated by a factor of 100—the true level of barium measured was both usual and safe.
What Is Agenda 21?
In so many words, the United Nations seeks to co-opt, via individual governments, and eventually, a “one-world government,” privately held land under the auspices of ensuring its “sustainability.” Worse still, the UN’s Agenda 21 has even laid out plans for “depopulation” or rather, “population control.” If it sounds like something out of George Orwell’s 1984, that is because Agenda 21’s tenets are eerily in line with the demented alternate reality Orwell himself had imagined while scribbling the pages of his famed novel. “Sustainable development” is the catch-phrase to be leery of.
