Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Climate change denial#Discussing specific aspects of climate change science; Intergovernmental Panel on Climate Change#Challenges and controversies (the IPCC assessment reports, like the most recent IPCC Sixth Assessment Report summarise the state of the art of climate science at the time).
Many climate change impacts have been observed in the first decades of the 21st century, with 2024 the warmest on record at +1.60 °C (2.88 °F) since regular tracking began in 1850. [ 19 ] [ 20 ] Additional warming will increase these impacts and can trigger tipping points , such as melting all of the Greenland ice sheet . [ 21 ]
The PDF 1.4 specification allowed form submissions in XML format, but this was replaced by submissions in XFDF format in the PDF 1.5 specification. XFDF conforms to the XML standard.

The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management. In 2014, the Intergovernmental Panel on Climate Change harmonized the carbon dioxide equivalent (CO 2 e) findings of the major electricity generating sources in use worldwide.
Fourth National Climate Assessment (NCA4) 2017/2018 is a 1,500 page two-part congressionally mandated report by the U.S. Global Change Research Program (USGCRP) [1] —the first of its kind by the Trump administration, who released the report on November 23, 2018. [2]
