On 28 January 2009, the European Commission released a position paper, "Towards a comprehensive climate agreement in Copenhagen." [10] The position paper "addresses three key challenges: targets and actions; financing [of "low-carbon development and adaptation"]; and building an effective global carbon market". [11] Leading by example, the ...
This activity enabled those climate models, outside the major modeling centers to perform research of relevance to climate scientists preparing the IPCC Fourth Assessment Report (IPCC-AR4). For the CMIP3 a list of 20 different experiments were proposed, [ 3 ] and the PCMDI kept the documentation of all the global climate model involved. [ 4 ]
In January 2025, President Lula appointed Brazilian diplomat André Corrêa do Lago as the COP's president. [6] The decision was praised by Brazilian climate activists given Lago's history of leading climate justice discussions, among other things. [7] Lago is a veteran diplomat at Itamaraty (Brazil's Foreign Ministry) and a longtime climate ...
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
A National Adaptation Programme of Action (NAPA) is a type of plan submitted to the United Nations Framework Convention on Climate Change (UNFCCC) [1] by least developed countries, to describe the country's perception of its most "urgent and immediate needs to adapt to climate change". [2]
P-CAN - Place-based Climate Action Networks, a UK-based partnership between university researchers and the public, private and third sectors in tackling climate change, aiming to accelerate and sustain the transition to a low-carbon, climate-resilient society through the creation of local climate commissions. [30] PCD - Petersberg Climate Dialogue
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [13] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [14] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [15]
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
