WMO released new climate predictions on global temperatures in the next five years.The annual mean global temperature is likely to be at least 1° Celsius above pre-industrial levels (1850-1900) in each of the coming five years (2020-2024) and there is a 20% chance that it will exceed 1.5°C in at least one year, according to new climate predictions issued by the World Meteorological Organization (WMO). The Global Annual to Decadal Climate Update, led by the United Kingdom’s Met Office, provides a climate outlook for the next five years, updated annually.

The Paris Agreement Compatible (PAC) scenario illustrates a pathway for the transition of the EU’s energy system that is in line with EU leaders’ commitment to the Paris Agreement.

Southwestern China (SWC) has suffered from increasing frequency of heat wave (HW) in recent summers. While the local drought-HW connection is one obvious mechanism for this change, remote controls remain to be explored. Based on ERA-5 reanalysis, it is found that the SWC summer HWs are significantly correlated with sea-ice losses in the Barents Sea, Kara Sea and the Arctic pole.

Thirteen of the world’s largest dairy corporations combined to emit more greenhouse gases (GHGs) in 2017 than major polluters BHP, the Australia-based mining, oil and gas giant or ConocoPhillips, the United States-based oil company.

The unprecedented challenge of climate change requires rapid and deep transformations – in virtually all sectors and all parts of society – away from the prevailing carbon-intensive, high-emission modes of production and consumption.

The 2019 edition of the European Environment Agency (EEA) report on fluorinated greenhouse gases (F-gases) confirms the good progress achieved in 2018 by the European Union (EU) in phasing-down the use of hydrofluorocarbons (HFCs), a set of fluorinated gases with a high global warming potential (GWP) that is significantly contributing to climate

New research by the Transition Pathway Initiative finds that 29% of the largest publicly-listed industrial companies are set to align their emissions with the Paris Pledges by 2030, up from 24% in mid-2018.These companies are aligned with the emission reduction pledges made by national governments in the Paris Agreement.

Human-emitted greenhouse gases (GHGs) have resulted in a long-term and unequivocal warming of the planet. More than 90% of the excess heat is stored within the world’s oceans, where it accumulates and causes increases in ocean temperature.

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.
