Melting ice, submerged megalopolises, hungry white bears … among the images chosen to represent the effects of global warming, all too often those concerning human impact are missing. It is Mary Robinson, former President of the Irish Republic and High Commissioner for Human Rights, who proposed this key.

COP21: all about the Paris climate summit

On your own skin. In this TED video, Robinson, United Nations special envoy for climate change, proposes other points of view on the problem: like that of Anote Tong, president of the Republic of Kiribati, forced to buy land and insurance policies for when his people will be forced to migrate and leave the archipelago, threatened by rising sea levels; or that of a community of Ugandan women, at the mercy of drought and sudden floods that have altered the rhythm of the seasons, destroying the crops.

To pay the effects of climate change are often populations that are not helping to create them: for example the inhabitants of Malawi, who drive and consume very little but who, in January, were hit by an unprecedented flood, which reduced to their livelihoods.

To remain below the "+ 2 ° C" threshold would require an unprecedented economic revolution. A challenge for the industrialized countries, and even more for the emerging ones: because none of the great powers, recalls Robinson, has reached the current well-being without using fossil fuels. Developing countries should instead grow and support very poor populations by exploiting renewable energies: and without the support, including economic support, of the international community, it is impossible for them to make it.

Our solidarity is necessary. And if not disinterested, which is at least based on personal gain: we are all involved, concludes Robinson, who compares 2015 to 1945, for the crucial political decisions that are required of us. The video - a bit long, but worth it - is in English, with subtitles and transcription in Italian.
