The eastern or Chinese spot-billed duck is currently introgressing into the mallard populations of the Primorsky Krai, possibly due to habitat changes from global warming. [22] The Mariana mallard was a resident allopatric population – in most respects a good species – apparently initially derived from mallard-Pacific black duck hybrids ...
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
A 2018 perspectives article discussing tipping points in the climate system activated around 2 °C (3.6 °F) of global warming suggested that at this threshold, permafrost thaw would add a further 0.09 °C (0.16 °F) to global temperatures by 2100, with a range of 0.04–0.16 °C (0.072–0.288 °F) [52] In 2021, another study estimated that in ...

The global annual net loss of trees is estimated to be approximately 10 billion. [ 23 ] [ 24 ] According to the Global Forest Resources Assessment 2020 the global average annual deforested land in the 2015–2020 demi-decade was 10 million hectares and the average annual forest area net loss in the 2000–2010 decade was 4.7 million hectares ...
Updated 2022 estimates show that even at a global average increase of 1.5 °C (2.7 °F) over pre-industrial temperatures, only 0.2% of the world's coral reefs would still be able to withstand marine heatwaves, as opposed to 84% being able to do so now, with the figure dropping to 0% at 2 °C (3.6 °F) warming and beyond.

Mining: Mining can also lead to deforestation, as trees are cleared to access mineral resources. [21] [22] [23] Mining is the process of extracting minerals from the Earth's crust. It is a major industry in many parts of the world, and it is essential for providing raw materials for a variety of products, such as metals, minerals, and fuels.
The Billion Tree Tsunami was launched in 2014 by planting 10 billion trees, by the provincial government of Khyber Pakhtunkhwa (KPK) and Imran Khan, as a response to the challenge of global warming. Pakistan's Billion Tree Tsunami restored 350,000 hectares of forests and degraded land to surpass its Bonn Challenge commitment .
