The climate change
is any long-term significant change in the expected patterns of
of a specific

as a whole) over an appropriately significant period of time. Climate change reflects abnormal variations to the expected climate within the Earth's atmosphere and subsequent effects on other parts of the Earth, such as in the

In recent usage, especially in the context of

Defending our Oceans
Seen from space the Earth is covered in a blue mantle. It is a planet on which the continents are dwarfed by the oceans surrounding them and the immensity of the marine realm.
A staggering 80 percent of all the life on Earth is to be found hidden beneath the waves and this vast global ocean pulses around our world driving the natural forces which maintain life on our planet.
The oceans provide vital sources of protein, energy, minerals and other products of use the world over and the rolling of the sea across the planet creates over half our oxygen, drives weather systems and natural flows of energy and nutrients around the world, transports water masses many times greater than all the rivers on land combined and keeps the Earth habitable.

Protect ancient forests
Throughout the world, ancient forests are in crisis. Many of the plants and animals that live in these forests face extinction. And many of the people and cultures who depend on these forests for their way of life are also under threat. But the news is not all bad. There is a last chance to protect these forests and the life they support.
The world's ancient forests are truly diverse. They include boreal, temperate and tropical forests, coniferous and broadleaf forests, rainforests and mangroves. Together they maintain environmental systems that are essential for life on Earth.
They influence weather by controlling rainfall and evaporation of water from soil. They help stabilise the world's climate by storing large amounts of carbon that would otherwise contribute to climate change.
We have to stop the climatic change because if we do not
