What is the reason for the upward trend in atmospheric carbon dioxide since the late 1800s?
The upward trend in atmospheric carbon dioxide since the late 1800s is primarily attributed to human activities, particularly the burning of fossil fuels like coal, oil, and natural gas for energy and transportation. Deforestation and land-use changes also contribute by reducing the number of trees that can absorb CO2. Industrial processes and agricultural practices further release greenhouse gases, exacerbating the increase in atmospheric CO2 levels. This rise in carbon dioxide is a significant driver of climate change and global warming.

What makes African violet leaves stand up?
The reason they are reaching to the sun, they need more light, but not direct sunlight or they will receive burned spots. They know somehow that reaching upward they will get more light.
What northeastern state bordering new jersey has the motto ever upward?
New York State Motto is "Excelsior" which means "ever upward".
What is the answer of the riddle What lives in winter dies in summer and grows with its roots upward?
The answer to the riddle "What lives in winter, dies in summer, and grows with its roots upward" is an icicle. In winter, icicles form as water freezes, but they "die" in summer when temperatures rise and they melt away. The description of growing with roots upward refers to how icicles hang down from surfaces, resembling roots extending upward.

What best describes measurements of atmospheric carbon dioxide levels since 1958?
Atmospheric carbon dioxide levels have been steadily increasing since 1958, when consistent measurements began at Mauna Loa Observatory in Hawaii. This rise is primarily due to human activities such as burning fossil fuels and deforestation, which release CO2 into the atmosphere. The measurements show a clear upward trend, highlighting the impact of human activities on the Earth's climate.
The explanation of sublimation?
Sublimation is a process where a substance transitions directly from a solid to a gas without passing through the liquid state. This occurs when the atmospheric pressure is lower than the substance's vapor pressure at a certain temperature. Common examples include dry ice (solid carbon dioxide) turning into carbon dioxide gas without melting.
Why does helium rise while carbon dioxide sink?
Helium rises because it is less dense than the surrounding air. On the other hand, carbon dioxide sinks because it is more dense than the surrounding air. This difference in density causes helium to float upward and carbon dioxide to sink downward.
Why does the amount of carbon dioxide in the atmosphere goes down during the summer months?
The amount of atmospheric carbon dioxide follows a slow upward trend, superimposed by a saw-tooth pattern with a peak during the northern hemisphere summer and a low during the northern hemisphere winter. These short term fluctuations are due to the vigorous growth of plants during the warmer months. The sourthern hemisphere does not balance this effect because many of its evergreen trees continue to grow all year around, and because of the smaller land area.
Do xylem travel up or down?
Both, it takes water and Carbon Dioxide up and it lets out Oxegen.
Why do melts migrate upward?
Melts migrate upward due to their lower density compared to the surrounding solid rock. This buoyancy force causes the melts to rise towards the surface. Additionally, the presence of volatile components in the melts, such as water or carbon dioxide, can further enhance the upward migration due to their ability to reduce the melting temperature of rocks.
When the supply curve is upward sloping?
Supply curve will be upward sloping in two reason,the first reason is know as the income effect and the second is know as substitution effect.
What contributes to atmospheric carbon dioxide?
In the absence of anthropogenic activities, carbon dioxide (CO2) levels in the atmosphere would be fairly static. Animals exhale carbon dioxide, but vegetation converts this back into edible products that are then consumed by those animals. Similarly, rotting vegetation gives off carbon dioxide, but the vegetation is soon replaced by new vegetation that requires the same amount of carbon. The natural cycle contributes no net increase in carbon dioxide concentrations in the atmosphere. Even burning wood or paper has no net effect on atmospheric concentrations of carbon dioxide, although cutting down trees for wood or paper could do so if new trees are not allowed to grown and absorb as much carbon as the trees cut down. So, CO2 concentrations had remained around 260-280 parts per million (ppm) until the time of the Industrial revolution, when the level of CO2 began to rise in line with increasing use of fossil fuels. The increase from 260-280 ppm to the present 390 ppm of atmospheric carbon dioxide is almost entirely due to human activities. The main cause is by burning fossil fuels such as coal, oil and natural gas. Another important cause is deforestation, mainly as land-clearing for farming. _______________________________________________________________ There is absolutely zero scientific evidence to make the claim that carbon dioxide has ever been "fairly static". The science behind the levels of carbon dioxide differ vastly from the political viewpoint stated. CO2 has varied by about 800 years behind temperature. This is a well known trend for the past 650K years according to all available data. The current upward trend started well over 10,000 years ago, shortly after the temperatures started to rise. Carbon dioxide has always followed temperature. With the current warming trend now at over 10 degrees C, it is a normal and expected occurrence that CO2 levels would eventually follow. Levels as low as 190 ppm have been observed in the past 10,000 years, as well as levels (reported by Noble winning science experts from the 1800's) of well over 400 ppm. (Beck 2008). The overall trend for CO2 has been upward almost non stop for the past 9,300 years. There have been fluctuations, but this is the undisputed trend. Man's production of less than 6% of all CO2 is possibly a partial contributor to the current levels of CO2. That is a very possible scenario. Nature's production of 94% is a known cause of increase. To blame man as the sole reason for increase though is misleading and absolutely false. We know that the levels of CO2 rose over 100 ppm prior to man starting to use any coal. The one undisputed fact of CO2 increase is the know relationship between temperature and the levels of CO2 in our atmosphere. Temperature causes CO2 to rise. This is a known event. Human additions are a speculative (albeit possible) issue.
When a person drinks a soft drink through a straw where does the force came from that causes the soft drink to move upward?
Atmospheric pressure
Does the atmospheric pressure increase or decrease as you move upward away from sea level?
Atmospheric pressure decreases as you move upward away from sea level due to the decrease in the weight of the air above pushing down. This means that atmospheric pressure is lower at high altitudes and higher at lower altitudes, such as at sea level.
What happen during exhalation?
The act of exhalation itself is caused by the diaphragm relaxing and pushing upward on the lungs, forcing air out of them. This air is loaded with carbon dioxide, a dangerous waste product, so that is eliminated.
Why is there so much more carbon dioxide on Venus than Earth?
Venus has a stronger greenhouse effect than Earth because the atmosphere of Venus consists of about 96.5% Carbon Dioxide (CO2), which is a greenhouse gas, and the planet itself has virtually no water. Earth's atmosphere, by comparison, only contains about 0.03% CO2 and is comprised of about 70% water.Since Venus' atmosphere contains so much CO2, a vast majority of the infrared (heat) radiation that is radiated back upward from the surface after sunlight hits it, gets absorbed, redirected and essentially trapped within the atmosphere. As a result, temperatures within the atmosphere and on the surface rise to very high levels. Only when the temperature builds up so high, to about 730K (or 456.85°C), can heat finally begin to breakthrough and escape, thus leveling off the temperature.It is this high temperature that has basically boiled almost all of the water from Venus' surface and which also helps to contribute to the already massive greenhouse effect because water helps to control atmospheric CO2 by absorbing it.
