Plants got their start in water, and the move onto land by algae - like ancestors was quite challenging, requiring the evolution of the ability to deal
with fluctuations in temperature and access to water, as well as to more intense sunlight.
While it is theoretically possible for human and animal activities to affect the climate on Earth, the main factor
causing fluctuations in temperatures on this planet, as on Mars, is variability in energy output from the Sun.
Our study incorporated a similar geographic range and range
of fluctuations in temperature as the studies which have found a significant relationship between annual SSR and mean temperature [7], [11], [14].
While it is theoretically possible for human and animal activities to affect the climate on Earth, the main factor causing
fluctuations in temperatures on this planet, as on Mars, is variability in energy output from the Sun.
Much of the warming, he says, stems
from fluctuations in temperature that have occurred for millions of years — explained by complicated natural changes in equilibrium between the oceans and the atmosphere — and the latest period of warming will not result in catastrophe.
By studying
subtle fluctuations in the temperature of the cosmic microwave background, cosmologists have determined the total amount of energy in the universe and how the form it takes has changed over time.
Like gases in the atmosphere and water in the oceans, this fluid metal undergoes
random fluctuations in temperature and motion, analogous to the weather patterns we experience up top.
Brendan Godley at the University of Exeter, UK, and colleagues, analysed 26 years of data to see
if fluctuations in temperatures had an influence on sex ratios of turtles in North Carolina.
In 2003, researchers working with NASA's orbiting Wilkinson Microwave Anisotropy Probe (WMAP)
mapped fluctuations in the temperature of the CMB, which varies by only a few parts in 100,000 across the sky.
This inertia makes the building act like a thermal flywheel,
reducing fluctuations in temperature and causing the house to require very little supplemental heat to maintain that ideal temperature.
«Global warming is expected to cause extreme weather events, which may, in turn, result in large day - to -
day fluctuations in temperature,» said Hedvig Andersson, a cardiology researcher at the University of Michigan.
For example, if you go to the Arctic Ocean you will observe daily and
yearly fluctuations in temperature that are directly linked to Earth's spin on its axis (time of day) and the axial tilt relative to the sun (time of year).
If the validation period does not have as strong a trend and the proxies are not skillful at predicting shorter
timescale fluctuations in temperature, then the CE can be substantially lower.
It also provides it with great thermal mass, enabling the building to retain heat,
absorb fluctuations in temperature and reducing the need for central heating or cooling systems.»
After controlling
for fluctuations in temperature and precipitation, the team found that 2014 was not an anomaly: The shrub appeared to be consistently entering its weeklong pollination phase on the night of the full moon in July.
