ln India an unprecedented heat wave is occurring, which is bringing the country to its knees, and creating inconvenience not only for human beings, but also claiming victims among animal species, such as birds, very sensitive to the variations in temperature brought about by the Climate Crisis.
The warmest period in the country in the past1 22 years. These days India has had temperatures close to 50 °. Hundreds of birds are dying, crashing to the ground, against buildings, cars, killed by the extreme heat. Some associations and NGOs are trying to cope with the emergency by rescuing birds that are still alive but in critical conditions: pigeons, parrots, barn owls, birds of prey, all flying species are in danger and are dying.
Wildlife SOS rescued a black kite that crashed on New Delhi roads, rescuing and rescuing at least 200 birds in these days: "This summer we invite you all to keep bowls of water to save these feathered creatures from dehydration." Veterinarians ong Jivdaya Charitable Trust in Ahmedabad said: "This year has been one of the worst in recent times.
We have seen a 10% increase in the number of endangered birds."
Global warming and its causes
The predominant causes are to be found in human activity, due to the emissions into the earth's atmosphere of increasing quantities of greenhouse gases, with a consequent increase in the greenhouse effect and other factors that are always attributable to human activities.
The Kyoto Protocol, signed in 1997 and which as of November 2009 counts the adhesion of 187 States, aims to reduce these man-made greenhouse gases. The Paris Agreement, signed in November 2015, commits participating States to keep the global temperature rise well below 2 ° C compared to pre-industrial levels.
An increase in the global average temperature would lead to areas in the mid-latitudes more subject to desertification phenomena, also by virtue of the prolonged absence of atmospheric precipitation due to drought and heat waves.
The recession or retreat of glaciers since 1850 is the hydrogeological phenomenon for which the surface and thickness of terrestrial glaciers have generally decreased compared to the values they had in 1850.
It is a process that affects the availability of fresh water for the irrigation and for domestic use, on mountain excursions, on animals and plants that depend on the melting of the glacier and, in the long term, also on the level of the oceans.
Studied by glaciologists, the coincidence of glacier retreat with rising atmospheric greenhouse gases is often cited in evidential support of global warming. Mid-latitude mountain ranges such as the Himalayas, Alps, Rocky Mountains, Cascade Range and the southern Andes, not excluding isolated tropical peaks like Kilimanjaro in Africa, are showing signs of the greatest glacial loss.
