Do you know how climate change accurs and why it happens? Do you know what wwf-international is doing about it?
Answer 1:

Climate is an immensely complicated phenomenon that we are, perhaps appropriately, only scraping the very tip of the iceberg in terms of understanding it. We know (or strongly suspect) that climate change has happened in the past due to many, many factors, including:

(1) changes in the positions of landmasses due to continental drift, altering wind or ocean circulation patterns;

(2) volcanoes spewing dust, sulfur dioxide, or other aerosols into the atmosphere;
(3) changes in the energy output of the sun (how and why the sun does this we don't understand either, but we know that it does);
(4) changes in the distribution of vegetation, especially forests, on the Earth's surface, especially in regards to rainfall;
(5) changes in the Earth's orbit;
(6) debris kicked up by asteroid or comet impacts;
(7) changes in the composition of the atmosphere, especially in greenhouse gasses, which are in turn caused by:

(a) volcanoes spewing them out;
(b) releases from peat bogs, oceanic methane deposits, etc.
(c) destruction of forests (natural or artificial), releasing stored carbon into the atmosphere;
(d) evaporation of water from the ocean as part of normal weather due to the sun and other factors (this is the big one greenhouse-wise, but is itself amplified by other climate-changing effects);
(e) burning of fossil fuels by humans.

Possibility 7-e and its influences on 7-d are the ones that most environmentalists are most concerned about for two reasons, first because we are both causing it and second because it's the one cause that human policies can actually do something about directly; all of the others are mainly if not entirely natural and almost or completely beyond our control. Debate continues in the scientific community over which of this laundry list are most important, but there is general consensus that all of them do matter to some extent, including the human-induced effects.

I am not familiar with exactly what the World Wildlife Fund is doing about climate change at the moment, but I can tell you that they don't have the resources to fight climate change directly except maybe by putting out propaganda in order to educate people that it's a problem and that we humans have a hand in causing it. More likely what they are doing is trying to anticipate the effects that climate change will have on the wildlife that they're trying to protect, and planning and funding reserves that will enable said wildlife to survive the climate changes that are to come.
