How are scientist able to determine temperature and CO2 levels from specific years so long ago?
Proxies are used to reconstruct the temperature record before the historical period. Quantities such as tree ring widths, coral growth, isotope variations in ice cores, ocean and lake sediments, cave deposits, fossils, ice cores, borehole temperatures, and glacier length records are correlated with climatic fluctuations. Instrumental readings began to be recorded on a global basis in 1850, although readings exist for central England from the seventeenth century.
Until early in the nineteenth century, there was no direct measurement of atmospheric carbon dioxide (CO2) levels. Occasional, snapshot observations of carbon dioxide levels began, with some giving readings well above present levels and even well over 500 parts per million. These were all taken in or close to highly polluting urban areas such as central Paris, and were influenced by local factors and wind directions, so that no serious climate scientist could use these observations to estimate global concentrations of carbon dioxide at those times, especially in the face of more reliable data. One of the most reliable indicators of carbon dioxide levels now available are ice cores taken from the Antarctic, wherein air bubbles can be analysed for their carbon dioxide content. There was no industry or other local influence to affect the readings, and cores can be taken from over two hundred thousand years ago, covering the entire history of modern man.
What else can I help you with?
How could you determine the correct temperature range and salt concentration and pH for a specific enzyme?
Do a controlled experiment in which you get an enzyme and set them up in different temperature, salt concentration and pH levels and see which reacts the best.
Who came up with the concept of energy levels?
The concept of energy levels in atoms was developed by Niels Bohr in 1913 as part of his atomic model. Bohr proposed that electrons orbit the nucleus in specific energy levels, and that they need a specific amount of energy to jump between these levels.
Factors that determine what biome is found in an area of rainfall and temperature?
The primary factors that determine the biome in a particular area based on rainfall and temperature include temperature range, precipitation levels, soil type, and elevation. These factors influence the type of vegetation that can thrive in an area and consequently determine the biome, such as tropical rainforest, desert, grassland, or tundra. Temperature and rainfall interact to create distinct environmental conditions that support specific plant and animal species characteristic of different biomes.
What types of information would be most helpful in identifying a Biome?
The most helpful information in identifying a biome would include temperature range, precipitation levels, dominant vegetation types, and specific animal species that inhabit the area. This information can help determine the biome classification based on factors like temperature, rainfall, and biodiversity.
What temperature levels make a beanstalk plant grow best?
room temperature levels are best for a beanstalk plant.
Who was the scientist that said electrons are found in specific energy levels?
That was Niels Bohr

What are the factors that determine the carbonation levels in soda?
The factors that determine the carbonation levels in soda are the amount of carbon dioxide gas dissolved in the liquid, the temperature of the soda, and the pressure inside the container.

This climograph is for a city that would be located?
I'm unable to view the provided climograph as it requires visual information. If you can provide specific details about the climatic chart, such as temperature ranges, precipitation levels, and seasons, I can help determine the likely location of the city it represents.
What is the dew point temperature at which formation began?
The dew point temperature is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid. Formation of dew occurs when the air temperature drops to the dew point, leading to condensation on surfaces. This temperature varies based on humidity levels; higher humidity results in a higher dew point. To determine the specific dew point temperature at which formation began in a given context, the current temperature and relative humidity must be measured.
The major factors which determine aquatic biomes are?
The major factors that determine aquatic biomes include water temperature, sunlight availability, nutrient levels, and water depth. These factors influence the types of organisms that can survive and thrive in different aquatic environments.
What are the factors that determine the carbonation levels in soft drinks?
The factors that determine the carbonation levels in soft drinks include the amount of carbon dioxide gas added during production, the temperature of the liquid, and the pressure inside the container. These factors affect the amount of carbon dioxide that can dissolve in the liquid, leading to different levels of carbonation in the final product.
Which two levels of animal classification do scientist use the most?
Scientists use the genus and species levels of animal classification most frequently because they provide the most specific information about a particular organism. This system helps scientists accurately classify and differentiate between different species.
How can one accurately determine soil temperature without using a thermometer?
One way to accurately determine soil temperature without using a thermometer is to observe the behavior of plants and animals in the area. Certain plants and insects are sensitive to temperature changes and can indicate the approximate soil temperature based on their activity levels. Additionally, the presence of frost or ice on the ground can also provide clues about the soil temperature.
Determine what most organisms need to survive?
Most organisms need food, water, shelter, and the ability to reproduce in order to survive. Additionally, they require a suitable environment with appropriate temperature, oxygen levels, and other specific conditions for their survival.
