![]() They can be the remains of minuscule life forms or microscopic parts of plants and animals. Microfossils are tiny fossils, usually smaller than 4 mm in size. Each plant has different shaped pollen or spores so it is possible to identify the type of plant it came from under a microscope.ĭifferent plant species require different climatic conditions, therefore looking at the pollen in a layer of rock can be a good indication of the climate at the time when they were living. They have a strong outer case, so they are easily preserved as fossils if they are quickly covered in mud. Pollen and spores are produced in their millions. Plants produce pollen and spores that are particularly useful in helping to determine climate. If the depth of the water changes just a fraction, they cannot survive. They need a particular temperature, a specific depth of water and the right amount of light. Therefore, wherever fossil corals are found, it is possible to estimate the environment in which they lived in the past because of these specific environmental requirements. If the water conditions change, even by a relatively small amount, they cannot survive. For example, coral reefs live in tropical waters within a particular temperature range, specific depths and require certain light levels. Some can be very sensitive and do not adapt easily to change.

During hot weather, evaporation from both land and sea increases and can cause droughts in regions where there is low precipitation. Extra water vapour in the atmosphere falls again as extra rain, which can cause flooding. These include hurricanes, floods and droughts. Source: Our World in Data.Īs the Earth warms up, interactions between the oceans and atmosphere can amplify the frequency and intensity of weather events. Overall, deaths from natural hazards have seen a large decline over the past century, but meteorological, hydrological and climatological events have increased since 1980. This includes those from drought, floods, extreme weather, extreme temperature, landslides, dry mass movements, wildfires, volcanic activity and earthquakes. The number of global reported disasters caused by natural hazards since 1900. Over the past 35 years, there has been an almost fivefold increase in the recorded number of disasters caused by natural hazards, although not all were influenced by extreme weather events (source: III.ORG ). In the future, a warmer climate may cause more heatwaves, increase rainfall and increase the frequency and strength of storms.
