Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world
What changes could occur in the hydrologic cycle of our climate were to warm or cool significantly?
Climate change affects evaporation and precipitation Climate change is likely causing parts of the water cycle to speed up as warming global temperatures increase the rate of evaporation worldwide More evaporation is causing more precipitation, on average
What happens during the hydrologic cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation Evaporation is the process of a liquid’s surface changing to a gas In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor
What are the effects of climate change to the carbon cycle?
The biggest changes in the land carbon cycle are likely to come because of climate change Carbon dioxide increases temperatures, extending the growing season and increasing humidity Both factors have led to some additional plant growth However, warmer temperatures also stress plants
How does climate change affect the Philippines?
Impacts of climate change in the Philippines are immense, including: annual losses in GDP, changes in rainfall patterns and distribution, droughts, threats to biodiversity and food security, sea level rise, public health risks, and endangerment of vulnerable groups such as women and indigenous people
What changes when water evaporates?
Evaporation is the process by which water changes from a liquid to a gas or vapor Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor
What are three ways global warming might affect the water cycle?
How Climate Change Impacts Our Water Evaporation Warmer air can hold more moisture than cool air Precipitation When all that extra warm, extra wet air cools down, it drops extra rain or snow to the ground Surface Runoff and Stream Flow Oceans Snowpack Clouds Changes in Water Demand
What are the factors that affect seepage and runoff?
Meteorological factors affecting runoff: Type of precipitation (rain, snow, sleet, etc) Rainfall intensity Rainfall amount Rainfall duration Distribution of rainfall over the drainage basin Direction of storm movement Precipitation that occurred earlier and resulting soil moisture
What are some of the effects of climate change?
More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities As climate change worsens, dangerous weather events are becoming more frequent or severe
What are three possible causes of climate change?
Causes for rising emissions Burning coal, oil and gas produces carbon dioxide and nitrous oxide Cutting down forests (deforestation) Increasing livestock farming Fertilisers containing nitrogen produce nitrous oxide emissions Fluorinated gases are emitted from equipment and products that use these gases
How does climate change impact an ecosystem?
Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought
How does climate change affect the Philippine economy?
Climate change has the potential to disrupt crop productivity, and in turn affect domestic agricultural production, consumption, and food security Sustaining agricultural production growth to help achieve inclusive growth and poverty reduction is a key goal for the Philippine government
What are the major environmental problems in the Philippines?
Other environmental problems that the country is facing include pollution, illegal mining and logging, deforestation, dynamite fishing, landslides, coastal erosion, wildlife extinction, global warming and climate change
What are some examples of climate change?
These include warming temperatures and changes in precipitation, as well as the effects of Earth’s warming, such as: Rising sea levels Shrinking mountain glaciers Ice melting at a faster rate than usual in Greenland, Antarctica and the Arctic Changes in flower and plant blooming times
In which stage the Vapour changes into water?
Condensation is the process by which water vapor in the air is changed into liquid water Condensation is crucial to the water cycle because it is responsible for the formation of clouds
What will happen if water does not change into water Vapour in a water cycle?
So what would happen if there were no condensation stage? The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain) So the first answer is that there would be no clouds With no clouds, there would be no rain
What is the phase change that takes place when the water collected in the top of the cup begins to fall back into the bottom cup?
When the water vapor cools enough, the attractions between the molecules bring them together This causes the water vapor to change state and become tiny drops of liquid water The process of changing from a gas to a liquid is called condensation
What are the effects of climate change on water resources?
The main climate change consequences related to water resources are increases in temperature, shifts in precipitation patterns and snow cover, and a likely increase in the frequency of flooding and droughts
How does climate change affect the water system?
Climate change increases the likelihood of both heavy rains and extreme droughts Warmer air can hold more water vapour, one consequence of which is an increased frequency of heavy rainfall events Because of the warm air, more precipitation is falling as rain than as ice or snow
How does climate change affect water pollution?
Impact of water pollution Water pollution can have a multitude of negative effects on our environment, some of which can lead to even more problems and exacerbate climate change Increased levels of nutrients in water from things like fertilizer runoff can cause algae to grow at excessive rates
What are the factor affecting the runoff?
Meteorological factors affecting runoff: Rainfall intensity Rainfall amount Rainfall duration Distribution of rainfall over the watersheds
What are the different factor affecting the runoff?
Temperature, wind speed, and humidity are the major meteorological factors, which affect runoff Temperature, wind speed and humidity affect evaporation and transpiration rates, thus soil moisture regime and infiltration rate, and finally runoff volume
How does urbanization affect runoff and infiltration?
As urbanization progresses, urban land use changes, augmenting the area of impervious surfaces and, as a consequence, reducing infiltration during storm events and increasing direct runoff that eventually alters urban hydrologic processes [2,3,4]
