When the temperature is above 70 °F (21 °C) and the relative humidity is above 55 percent, mold begins to develop. [5] Collections kept in basements or environments with uncontrolled temperature and humidity are most likely to be impacted by a mold outbreak. [3] Mold is a dangerous library pest because of the damage it causes to the collections.
Humidity levels in an indoor environment need to be accounted for based upon season and temperature. If humidity levels do not agree with the time of the year and the temperature during seasons, mold infestation and deterioration of the building will occur due to moisture.
The effects of climate change on the water cycle have important negative effects on the availability of freshwater resources, as well as other water reservoirs such as oceans, ice sheets, the atmosphere and soil moisture. The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation.
If a house is artificially humidified, by the use of a humidifier, during the winter, this can create conditions favorable to mold. Moving air may prevent mold from growing, since it has the same desiccating effect as low humidity. Mold grows best in warm temperatures, 25 to 30 °C (77 to 86 °F), although growth may occur between 0 and 35 °C ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
La Niña occurs when the ocean's surface temperatures in the central and east-central equatorial Pacific (circled below) reach a specific cooler-than-average level, which can then affect ...
Water is one of the agents of deterioration. Its effects can be seen in these flood-damaged library books. The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects (such as collections held by galleries, libraries, archives and museums). [1]
With higher temperature and humidity, viruses can’t survive outside a host as long. Research suggests flu viruses in high humidity can cling to water molecules and then fall out of the air. That ...
