Global Climate Change01:50

Global Climate Change

28.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Linearization and Approximation01:26

Linearization and Approximation

51
Linearization is a mathematical technique used to approximate complex, nonlinear functions with simpler linear models in the vicinity of a chosen reference point. The method is based on the idea that, although a function may be difficult to evaluate exactly, its behavior near a specific input value can often be closely approximated by the tangent line at that point. This approach is particularly useful when small deviations from a known value are involved.Consider the square root function, for...

What is Climate?01:16

What is Climate?

20.6K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Application of Linearization and Approximation

87
A drone flying through complex terrain often relies on more than one sensing method to estimate small changes in altitude. Along with direct measurements, air pressure provides a useful indirect indicator of vertical movement. Atmospheric pressure decreases as altitude increases, and this relationship is commonly described using an exponential model. Although accurate, converting pressure measurements into altitude values requires calculations that are too complex to perform repeatedly during...

Accuracy, limits, and approximation01:28

Accuracy, limits, and approximation

1.1K
Accuracy, limits, and approximations are common in many fields, especially in engineering calculations. These concepts are imperative for ensuring that a given value is as close as possible to its true value.
Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
The accuracy of any solution is based on the...

Linear Approximation in Frequency Domain01:26

Linear Approximation in Frequency Domain

363
Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear....

Area of Science:

  • Human evolutionary biology
  • Environmental science
  • Architecture and climate

Background:

  • Human homes represent an engineered indoor environment, but evolutionary influences on indoor climate preferences are understudied.
  • Understanding indoor climate preferences is crucial as they relate to human fitness and well-being.
  • Previous research has not typically incorporated evolutionary predictions regarding indoor climate.

Purpose of the Study:

  • To investigate human preferences for indoor climate by analyzing data from homes across the USA.
  • To compare indoor home climates to global outdoor climate data and assess alignment with human physiological parameters.
  • To identify global outdoor regions with climates similar to those preferred indoors by humans.

Main Methods:

  • Citizen scientists collected indoor climate data from 37 homes in the USA.
  • A climate dissimilarity index was used to compare indoor home climates with global terrestrial climate data (67,420 grid cells).
  • Human and non-human primate thermoneutral zones (TNZ) were compared with the collected indoor climate data.

Main Results:

  • The average indoor climate of study homes closely resembled the outdoor climate of west central Kenya.
  • Indoor home climates generally aligned with the thermoneutral zone (TNZ) of humans and other primates.
  • The study identified the geographical distribution of global outdoor climates most similar to the studied indoor environments.

Conclusions:

  • Human indoor climate preferences appear to be shaped by factors related to evolutionary fitness.
  • The findings suggest a potential link between preferred indoor climates and the thermoneutral zone (TNZ), supporting evolutionary hypotheses.
  • This research provides a foundation for understanding the geographical distribution of ideal indoor climates globally.
