    Madhya Pradesh: Home to the Highest Number of Vultures

    Madhya Pradesh has now become the state with the highest number of vultures in India. In a recent census conducted by the Forest Department, the vulture population reached 12,981. The census covered 16 circles, 64 divisions, and 9 protected areas in the state. Since the census began in 2016, the vulture population has steadily increased, from 8,397 in 2019 to 10,845 in 2024.

    There are 7 species of vultures in Madhya Pradesh, with 4 being local and 3 migratory. The winter season is ideal for conducting the census as both local and migratory vultures can be easily counted.

    Vultures are large birds of prey that primarily feed on carrion (dead animals). They play a crucial role in the ecosystem by cleaning up animal remains, which helps prevent the spread of diseases. Vultures have sharp beaks, strong talons, and excellent eyesight to locate food from great distances.

    January 2025 was the warmest January on record

    January 2025 was the warmest January on record, despite the presence of La Niña, a climate pattern that typically brings cooler global temperatures. According to the Copernicus Climate Change Service (C3S), the global average temperature for January 2025 was 13.23°C, which is 0.09°C warmer than the previous record set in January 2024 and 0.79°C above the 1991-2020 average.

    This record-breaking warmth comes on the heels of 2024 being the hottest year on record, with global average temperatures rising 1.5°C above pre-industrial levels for the first time. Scientists have noted that global temperatures have stayed above the 1.5-degree mark for 18 of the last 19 months.

    Despite La Niña’s cooling effect, ocean temperatures in the eastern Pacific remained above normal, suggesting that the shift toward La Niña may be slowing or stalling. The Arctic also experienced unusually high temperatures, with parts of the Canadian Arctic seeing temperatures 30°C (54°F) warmer than average.
