TERMITES Global methane emissions from termites and their mounds are estimated to be about 11% of the global methane emissions from natural sources or about 2-20 Tg per year.

PATHWAYS TO NET-ZERO

According to the IPCC, the remaining budget to limit global warming to 1.5ºC with a 50% probability is about 500 GT of CO 2 (IPCC, 2021). In top-down scenarios, annual CO 2 emissions are halved by around 2030 and reach net-zero by mid-century. Non-CO 2 GHGs such as nitrous oxide (N 2 O) and methane (CH 4

FY 2022 EPA Budget in Brief

The FY 2022 Budget includes an additional $60 million to conduct research and deepen our knowledge of the impacts of climate change on human health and the environment. This investment more than doubles EPA’s climate change research while providing additional investments to decrease emissions of methane and hydrofluorocarbons.

carbon budget is practically impossible. Consequently, to limit global warming to 1.5°Celsius above pre-industrial times, greenhouse gas emissions must be reduced to net-zero as soon as possible, and then CO 2 must be permanently removed from the atmosphere to bring the total mass of greenhouse gases in the atmosphere

Global Warming of 1.5°C, the 2018 report by the Intergovernmental Panel on Climate Change (IPCC), makes clear that a “rapid and far-reaching” transition is required to limit the impact of climate change to 1.5 degrees Celsius.1 Doing so would require staying within the cumulative carbon budget of 570 gigatonnes of carbon dioxide (GtCO 2

1.5°C, global net anthropogenic CO 2 emissions decline by about 45% from 2010 levels by 2030 (40–60% interquartile range), reaching net zero around 2050 (2045–2055 interquartile range). For limiting global warming to below 2°C with at least 66% probability CO 2 emissions are projected to decline by about 25% by 2030 in most pathways (10–
