Himalayan pencil cedar (Juniperus polycarpos) is an evergreen tree distributed from Afghanistan, Baluchistan, Kagan valley, Kashmir, Lahaul-Spiti to upper reaches of western Tibet. In the western Himalaya treeline of the Juniperus polycarpos is not well defined because of the topographical barriers and variation in orography.

Disastrous bushfires during the last months of 2019 and January 2020 affected Australia, raising the question to what extent the risk of these fires was exacerbated by anthropogenic climate change.

Equilibrium climate sensitivity, the global surface temperature response to CO$_2$ doubling, has been persistently uncertain. Recent consensus places it likely within 1.5‐4.5K. Global climate models (GCMs), which attempt to represent all relevant physical processes, provide the most direct means of estimating climate sensitivity.

After more than 10,000 years of relative stability—the full span of human civilization—the Earth’s climate is changing. As average temperatures rise, climate science finds that acute hazards such as heat waves and floods grow in frequency and severity, and chronic hazards, such as drought and rising sea levels, intensify.

The United in Science Report has been created by the world’s leading climate science organizations who have joined forces to produce a unified assessment in preparation for the United Nations Climate Action Summit.

A new guide from Future Climate for Africa highlights two approaches researchers use to communicate climate projections, and the associated uncertainties, in west and southern African contexts.

A new report by Australian climate experts warns that "climate change now represents a near- to mid-term existential threat" to human civilization.

The Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC) – the body widely recognized as the international authority on climate change — give clear evidence of increased warming across Africa. The reports put forward a powerful case that increases in global temperatures are the result of human-induced climate change.

The Climate Council’s report, ‘Climate Cuts, Cover-Ups and Censorship’ provides a detailed overview of the Australian government’s approach to climate change since the election of the Liberal-National Coalition government in 2013.

The campaign to support the protesters has been launched by an international group of 22 scientists spanning a range of disciplines; several of them are renowned climate specialists.
