6 January: A study published in Scientific Reports comparing projected heat-related deaths from climate change with COVID-19 mortality rates across 38 global cities found that in half, annual heat-related deaths would likely exceed COVID-19 death rates within 10 years if global temperatures rise by 3.0 °C above pre-industrial levels.
Shared Socioeconomic Pathways (SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [2] They are used to derive greenhouse gas emissions scenarios with different climate policies.
The 2001 Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR) concluded that the measured impact of recent solar variation is much smaller than the amplification effect due to greenhouse gases, but acknowledged that scientific understanding is poor with respect to solar variation.

Emissions need to be decreasing now and roughly cut in half in the next seven years, the UN Intergovernmental Panel on Climate Change warned in their latest report
The final synthesis report was finished in March 2023. It includes a summary for policymakers and was the basis for the 2023 United Nations Climate Change Conference (COP28) in Dubai. [1] The first of the three working groups published its report on 9 August 2021, Climate Change 2021: The Physical Science Basis.
A severe solar storm may supercharge the northern lights from Friday through the weekend, with a chance to see auroras as far south in the U.S. as Alabama. ... A NASA spacecraft orbiting about 1 ...
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
