In a 2024 survey, 76.3% of responding IPCC lead authors and review editors projected at least 2.5 °C of global warming by 2100; only 5.79% forecast warming of 1.5 °C or less. [98] January: the World Economic Forum projected that, by 2050, directly and indirectly, climate change will cause 14.5 million deaths and $12.5 trillion in economic losses.
A BBC weather forecast for the year 2050 shows that summer temperatures of 38 °C for the UK are "par for the course". The probable range by which the planet will warm over the next century is between 1.4 °C and 5.8 °C. Or, says Attenborough, "to put it another way, the impact of global warming will be somewhere between severe and catastrophic."
The car mostly received a cynical reception, Red Bull Racing's Mark Webber observed that "it's good Honda is going green - but there are still 35 private jets parked 20 Kilometres down the road." [ 7 ] Briggs commented that "Honda's 'Earth Car' may have attracted cynicism, but the issues it highlights are moving up motorsport's agenda."
2 November: a study published in Oxford Open Climate Change (co-author: James E. Hansen) projected that the recent decline of aerosol emissions should increase the global warming rate of 0.18 °C per decade (1970–2010) to at least 0.27 °C per decade, so that "under the present geopolitical approach to GHG emissions", warming will exceed 1.5 ...
Publicity has surrounded claims of a global warming hiatus during the period 1998–2013. The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend, and so subsequent annual temperatures gave the appearance of a hiatus: by January 2006, it appeared to some that global warming had stopped or paused.

[B.1] Global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5 °C and 2 °C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades.
Attempts to suppress scientific information on global warming and other issues have been described by Chris Mooney as constituting a Republican War on Science. [ 45 ] In 2008, Jason Burnett, who was senior adviser on climate change in the EPA, claimed Dick Cheney 's office had sought to remove references to climate change in a testimony given ...
For the extended RCP2.6 scenario, global warming of 0.0 to 1.2 °C is projected for the late 23rd century (2281–2300 average), relative to 1986–2005. [34] For the extended RCP8.5, global warming of 3.0 to 12.6 °C is projected over the same time period. [34]
