what are three indicators of climate change quizlet

changes in polar and glacial icenot only risk of diseases and infections, but also injury death due to extreme conditions such as hest waves flood tornadoes snowstorms lightnening strick changes in heat distribution over earths surface led to changes in wind patterns desertificatiom droughts and other outcomes.

Typically, warmer weather will cause organisms to proliferate.

Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. Individual events such as forest fires are recorded in tree-rings. ... Few global trends have been as controversial as climate change and the Earth’s warming.

Other proxies include ice cores, tree rings, and sediment cores (which include diatoms, foraminifera, microbiota, pollen, and charcoal within the sediment and the sediment itself).Past climate can be reconstructed using a combination of different types of proxy records.

These records can then be integrated with observations of Earth's modern climate and placed into a computer model to infer past as well as predict future climate.Foraminifera, also known as forams, and diatoms are commonly used climate proxies. Scientists measure conditions such as temperature and precipitation directly in order to learn more about climate change. In addition, since each species has a particular set of ideal growing conditions, species composition at a particular site at a particular time may indicate past environmental conditions.Combinations of proxy data are generally used to reconstruct records for past climate. Since it is not possible to go back in time to see what climates were like, scientists use imprints created during past climate, known as proxies, to interpret paleoclimate.

For example, warmer average temperatures could increase air conditioning costs and affect the spread of diseases like Lyme disease, but could also improve conditions for growing some crops. To ensure the clear and concise communication of global climate change, the number of indicators could be around five, and certainly fewer than 10. Scientists take samples from the center of the coral. Nearly 97% of all scientists agree that climate change is real and that it is caused primarily by human activities (anthropogenic) It is likely that most of the climate change in the current era is the result of human activities Human activities have increased concentrations of greenhouse gases in the atmosphere No one doubts it is happening. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events – like heavy rainstorms and record high temperatures … precipitation

The two are the same thing. Researchers believe that unusual wind patterns have helped increase the melting of ice in the Arctic. For example, the eastern United States experienced a cold and snowy winter in 2014/2015, but this short-term regional weather phenomenon does not negate the long-term rise in national and global temperatures, sea level, or other climate indicators.

Climate has both long term trends and short term variability.

For example, climate typically controls what types of vegetation grow in a particular area. Additionally, How does this effect the oceans acidity?In which ways does climate effect health? According to this theory, changes in the shape of Earth's orbit around the sun (eccentricity), variations in Earth's axial tilt (obliquity), and the tendency for Earth to 'wobble' with respect to the direction of its rotational axis (precession) affect climate. More extreme variations in weather are also a threat to society. 4 Most of the warming occurred in the past 35 years, with the six warmest years on record taking place since 2014. . The coexistence of short and long term trends occuring simultaneously through time complicates our ability to unravel climate change.The science of paleoclimatology is important for past, contemporary, and future issues.
