Greenhouse gas (GHG) emissions contribute to global warming across the world, regardless of where the emissions originate. Yet the impact of global warming varies widely depending on how vulnerable a location or economy is to its effects. Global warming is on the whole having negative impact, which is predicted to worsen as heating increases ...
Through the creation of multilateral treaties, agreements, and frameworks, international policy on climate change seeks to establish a worldwide response to the impacts of global warming and environmental anomalies. Historically, these efforts culminated in attempts to reduce global greenhouse gas emissions on a country-by-country basis. [1]
These suspicions seemed to be proven correct when in December 2009 the BNP released a 40-page document denying that global warming is a "man-made" phenomenon. [235] The party reiterated this stance in 2011, as well as making claims that wind farms were causing the deaths of "thousands of Scottish pensioners from hypothermia ". [ 236 ]
Similar to Canada, Russia is both a net exporter of fossil fuels, and a country that could benefit from moderate global warming. Especially before 2010, Russian leaders would sometimes make dismissive statements about man made global warming, and could be somewhat obstructive to international climate change negotiations.
A review of action on climate since the Paris agreement calls for an end to fossil fuels without carbon capture.
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).
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.
