Europe's largest bank, HSBC, is donating $100m to perform the biggest field experiment on the effects of climate change to date.

Following reports of economic and environmental fallout caused by global warming, the bank will be joining forces with environmental organisations and charities.

"Several programmes will be funded by the $100m donation to climate change charities," Reuters quoted HSBC on Tuesday.

It is the largest ever donation by a British company, the bank said.

The donation comes after an influential report last year warned of severe economic and environmental fallout from the global warming, HSBC said. It will fund research by four charities on the impact of climate change over the next five years.

The four charities receiving funds are The Climate Group, Earthwatch Institute, Smithsonian Tropical Research Institute and WWF.

Their studies will include the impact of climate change on some of the world's major cities, monitoring the major tropical rainforests and improving management of water supplies from the Yangtze, Amazon, Ganges and Thames rivers.

Numerous Christian organisations and charities are also raising awareness of climate change.

Christian Aid has recently unveiled a life-saving eco-house, planted at the Eden Project to highlight the impact of climate change on communities worldwide. The charity will also feature the ultimate Green Garden at the upcoming Grand Designs Live ExCel London, which will teach visitors how to stylishly transform their own gardens while helping to tackle climate change.
