NOAA ANNUAL GREENHOUSE GAS INDEX (AGGI)
The AGGI is a measure of the climate-warming influence of long-lived trace gases in the atmosphere and how that influence has changed since the onset of the industrial revolution.

Global Warming Has Accelerated: Are the United Nations and the Public Well-Informed?
Global temperature leaped more than 0.4°C (0.7°F) during the past two years, the 12-month average peaking in August 2024 at +1.6°C relative to the temperature at the beginning of last century (the 1880-1920 average).

World Weather Attribution
When an extreme weather event occurs, people often ask: is climate change to blame? For decades, climate scientists have answered that question in general terms – that as the planet warms, we can expect many of these weather events to become more frequent and extreme. World Weather Attribution (WWA) scientists quantify how climate change influences the intensity and likelihood of an extreme weather event. They often do this using weather data and computer modelling, and often immediately in the aftermath of the extreme event.

Global Tipping Points
Harmful tipping points in the natural world threaten humanity by disrupting life support systems and societal stability. The effects of tipping points will be transmitted and amplified throughout our globalised world. To mitigate these risks, we should focus on positive tipping points—opportunities where beneficial changes become self-sustaining. History shows rapid societal shifts are possible.

Data
State of the Global Climate 2024
The clear signs of human-induced climate change reached new heights in 2024, which was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average.
