Explainer: How the rise and fall of CO2 levels influenced the ice ages
Jul 2, 2020 · Antarctic reconstructed air temperature (red line) at Dome Fuji site Antarctica using isotope modelling from Uemura et al (2018) and Antarctic composite ice core atmospheric CO2 data (blue line) from Bereiter et al (2014).Data spans the period from 800,000 BCE to 1980 CE. Chart by Carbon Brief using Highcharts.. While the CO2 concentrations provide a good representation of global average ...
Factcheck: How electric vehicles help to tackle climate change
May 13, 2019 · Electric vehicles (EVs) are an important part of meeting global goals on climate change. They feature prominently in mitigation pathways that limit warming to well-below 2C or 1.5C, which would be inline with the Paris Agreement’s targets.

Analysis: Why scientists think 100% of global warming is due to …
Dec 13, 2017 · The extent of the human contribution to modern global warming is a hotly debated topic in political circles, particularly in the US. During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”. ...
Analysis: UK electricity from fossil fuels drops to lowest level since ...
Jan 3, 2024 · West Burton in Nottinghamshire closed in March, then Drax in Yorkshire closed in April, followed by Kilroot in Northern Ireland at the end of September.. Only Ratcliffe in Nottinghamshire, operated by utility firm Uniper, remains operational. It plans to close in September 2024, ahead of the government’s ambition to end coal power by October 2024.. While the UK saw a major coal-to-gas ...
Analysis: How well have climate models projected global warming?
Oct 5, 2017 · Scenario B assumed a gradual slowdown in CO2 emissions, but had concentrations of 401ppm in 2016 that were pretty close to the 404ppm observed.However, scenario B assumed the continued growth of emissions of various halocarbons that are powerful greenhouse gases, but were subsequently restricted under the Montreal Protocol of 1987. Scenario C had emissions going to near-zero after the year 2000.
Factcheck: Why the recent ‘acceleration’ in global warming is what ...
Apr 4, 2024 · Comparison of historical and future warming projections from a continuation of the 1970-2023 linear trend (top left), the IPCC AR6 assessed warming range for SSP2-4.5 (top right), the CMIP6 multimodal mean and range for SSP2-4.5 (bottom left) and Hansen et al 2023 (bottom right). Blue dots and red dashed lines show observations and trends, while the black lines and yellow shading show model ...
Explainer: Will global warming ‘stop’ as soon as net-zero emissions …
Apr 29, 2021 · Media reports frequently claim that the world is facing “committed warming” in the future as a result of past emissions, meaning higher temperatures are “locked in”, “in the pipeline” or “inevitable”, regardless of the choices society takes today. The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions ...
CMIP6: the next generation of climate models explained
Dec 2, 2019 · Likely ECS range (e.g. with an estimated 66% chance of occuring) from the IPCC AR5 (black bar), CMIP5 model ECS values (grey), and CMIP6 model ECS values (blue). Chart by Carbon Brief using Highcharts.. Researchers are currently looking into what is driving these high ECS values. In a number of models the increase in ECS appears to be due to their improved representation of clouds and aerosols ...
Explainer: Desertification and the role of climate change - Carbon …
Aug 6, 2019 · Defining desertification. In 1994, the UN established the United Nations Convention to Combat Desertification (UNCCD) as the “sole legally binding international agreement linking environment and development to sustainable land management”. The Convention itself was a response to a call at the UN Earth Summit in Rio de Janeiro in 1992 to hold negotiations for an international legal ...
