The IPCC's Fourth Assessment Report in 2007 asserted that climate change is primarily caused by human activities, marking a pivotal moment in climate advocacy. The Paris Agreement, adopted in 2015 by 196 countries, aimed to limit global warming to well below 2 degrees Celsius, representing a unified global commitment to address climate change.
Climate change has become a concern for a number of disciplines due to its potentially catastrophic impacts on environmental systems, wildlife, nature, and humans.Climate change poses a serious threat to the global economy as economic development, especially in the West, has been largely dependent on the extraction and burning of fossil fuels since the Industrial Revolution.

In 2013, a study which found that out of over 4,000 peer-reviewed papers on climate science published since 1990, 97% agree, explicitly or implicitly, that global warming is happening and is human-caused. [37] [38] Surveys of scientists' views on climate change – with a focus on human caused climate change – have been undertaken since the ...
Climate solutions provide hope that global warming can be curbed. The world has lost decades in mobilizing against climate change, because of denialism, misinformation and inertia, among other ...
The site hosts various articles addressing the merit of common objections to the scientific consensus on global warming, such as the claim that solar activity (rather than greenhouse gases) is responsible for most 20th and 21st century global warming, or that global warming is natural and/or not harmful to humans. Each article, referred to as ...
Human-caused increases in greenhouse gases are responsible for most of the observed global average surface warming of roughly 0.8 °C (1.5 °F) over the past 140 years. Because natural processes cannot quickly remove some of these gases (notably carbon dioxide) from the atmosphere, our past, present, and future emissions will influence the ...
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).
Scientific consensus on causation: Academic studies of scientific agreement on human-caused global warming among climate experts (2010–2015) reflect that the level of consensus correlates with expertise in climate science. [435] A 2019 study found scientific consensus to be at 100%, [436] and a 2021 study concluded that consensus exceeded 99% ...
