Climate denial groups may also argue that global warming has stopped, that a global warming hiatus is in effect, or that global temperatures are actually decreasing, leading to global cooling. These arguments are based on short-term fluctuations and ignore the long-term pattern.
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).
Projections of future climate change suggest further global warming, sea level rise, and an increase in the frequency and severity of some extreme weather events and weather-related disasters. Effects of global warming include loss of biodiversity, stresses to existing food-producing systems, increased spread of known infectious diseases such ...
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% ...
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 climate crisis took a hefty economic toll in 2024, with just 10 disasters causing over $200bn in damage, according to a new report by Christian Aid.. The report, released on Monday, lists the ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. 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 ...
From 2013 to 2023, U.S. insurance companies paid $655.7 billion in natural disaster claims with the $295.8 billion paid from 2020 to 2022 setting a record for a three-year period, [165] and after only the Philippines, the United States lost the largest share of its gross domestic product in 2022 of any country due to natural disasters while ...
