climate change
The causes of cilmate change are variations in sunlight intensity and human activities.
Climate change is any long-term change's in the expected weather of a specific region over an period of time. Climate change reflects on variations to the climate within the atmosphere and effects on other parts such as in the ice caps, which took millions of years to produce.
Factors that can shape climate are called climate forcings. These include change's in solar radiation, change's in the Earth's orbitand and changes in greenhouse gas. Some parts of the climate system, such as the oceans and ice caps, respond slowly to climate forcing because of their large mass. The climate changes can take centuries or longer to fully respond to the new change's.

tipe of clouds
Instead of waiting for the news to hear the weather you can now find out your by being able to identify each characteristics of the clouds above you, if there is any!!!!!!!!!!!!!
There are three tipe of clouds
Cirrus clouds,
Cumulus clouds,
Stratus clouds.
Cirrus clouds
Cirrus clouds refer to atmospheric clouds that are thin, wisplike strands. These clouds form sheet's called cirrostratus. Sometimes at high altitudes another tipe of cirrus clouds is formed called cirrocumulus, a pattern of small wisplike strands which include droplets of supercooled water.
A high number of cirrus clouds usually signals a change in weather in the near future. Cirrus clouds can also be the be the starting of a thunderstorm. A large shield of cirrus and cirrostratus at high altitude Leeds to hurricanes or typhoons.
Cumulus clouds
Cumulus clouds are a type of cloud with noticeable vertical development and clearly defined edges. Cumulus means "heap" or "pile" in Latin. They are often described as "puffy" or "cotton-like" in appearance. Cumulus clouds may appear alone, in lines, or in clusters.
Cumulus clouds, that appear as small or medium sized puffy shapes in the sky, often occur in fair weather. However, cumulus clouds can grow into cumulonimbus clouds which may produce heavy rain, lightning, severe and strong winds, hail, and even tornadoes. A group of Cumulus clouds will often grow into cumulonimbus storm clouds.
Stratus clouds
The term stratus is used to describe flat, hazy, featureless clouds of low altitude varying in color from dark gray to nearly white. These clouds are fog formed either through the lifting of morning fog or when cold air moves at low altitudes over a region. These clouds do not usually bring heavy precipitation, although drizzle and snow may occur.

Tsunamis
Tsunamis are often called tidal waves. This is misleading, because tsunamis are not related to waves. Caused by earthquakes or volcanic activity. It can be hundreds of kilometers in length. It is a chain of fast moving waves caused by fast changes in the ocean. Usually, a tsunami starts suddenly. It will begin as normal waves and change to a very big wave very quickly. The waves travel across an ocean without losing energy. They can remove sand from beaches, destroy trees, damage houses and even wipe out whole towns. If the slope of the coast is shallow, the water may pull back for many hundreds of metres. People who do not know of the danger will often remain at the shore. Tsunamis can not be prevented, but there are ways to help stop people from dying from a tsunami. An earthquake that caused the tsunami can be felt before the wave gets to the shore, people can be warned to go somewhere safe mainly high up land such as mountains.
Drawbacks are a brief warning of a Tsunami; many survivors say that the drawback is followed by a sucking sound. People, who observe drawback, can survive only if they immediately run for high ground.
