With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns.

The Climate Would Be Very Erratic If the oceans were converted into land, then the water cycle would be disturbed and the amount of precipitation on land areas would reduce significantly. This would lead to droughts and a high variance of land climate.

The land would absorb the heat faster and release it back into the atmosphere at night. Due to less water on the planet there would be less heat absorbed and less clouds. This would mean that much of the planet would have either desert like conditions or be very humid and rainforests would be more common.

Mountain and arctic ecosystems and species are particularly sensitive to climate change. Projected warming could greatly increase the rate of species extinctions, especially in sensitive regions.

desert biome

The Australian tundra is a frozen desert of sorts and is located solely on the Antipodes Subantarctic Islands, which are made up of 5 island groups. This area is marked with grassland and shrubs as well as algae and lichen on the rocks.

A home to many animals, the Australian tropical savanna is one of the world’s largest tropical savannas. The world’s other savannas cover two fifths of Africa and large amounts of India and South America.

The vast savanna sweeping across more than 1.5 million square kilometres of Northern Australia is one of the greatest natural areas of the world. It is the world’s largest expanse of savanna left in good condition, since globally ~70% of the area of original savanna has been lost.

Grasslands have many names—prairies in North America, Asian steppes, savannahs and veldts in Africa, Australian rangelands, and pampas, llanos and cerrados in South America.

Grasslands in Australia are known as the Downs. Temperate grasslands are areas of open grassy plains that are sparsely populated with trees. Various names of temperate grasslands include pampas, downs, and veldts.

Grasslands are valued for pastoral grazing as many native tussock grasses and perennial herbs were palatable to stock.
