climate science

The record-shattering heat over the summer has raised the possibility that 2023 could finish the year above the 1.5°C warming threshold set by the Paris Agreement. Zeke Hausfather examines the nuances of tihis threshold across the different temperature reporting data sets.

A recent analysis by The Washington Post uses Berkeley Earth’s time-series data to reveals how some regions are warming at a slower rate relative to the global average.

Berkeley Earth’s new high-resolution data set will represent a quantum leap forward in the ability to represent the long-term impacts of climate change at the local level.

In this guest blog post, originally published in Carbon Brief, Berkeley Earth Research Scientist Dr. Zeke Hausfather fact checks the recent reemergence of claims that global warming has ‘paused’ over the last eight years.

Extreme heat is the most costly of all extreme weather phenomena, both in terms of its impact on human health and wellbeing, as well as its economic impact. In this episode we talk with Eleni Myrivili, Chief Heat Officer for the City of Athens, and Senior Advisor for the Atlantic Council, about the ways data is being used to build urban resilience in the face of extreme heat events caused by climate change.

In celebration of Earth Day 2022, Data Points is thrilled to welcome climate stripes creator Professor Ed Hawkins for a conversation with Berkeley Earth Lead Scientist Dr. Robert Rohde about the importance of making climate science accessible, the ongoing efforts to “rescue” historic climate data, and why filling the gaps in the historical climate record is essential to crafting future adaptive strategies. 

Characterizing the relationship of extreme weather events to man-made global warming is essential for crafting effective mitigation policies and adaptation strategies.

In the first episode of our 2022 Data Points series, we are honored to welcome Abubakr Salih Babiker, Erick Otenyo, and Marta Baraibar of the IGAD Climate Predications and Applications Center (ICPAC) to discuss the essential nature of climate services and early warning systems in climate change adaptation.

As part of their commitment to supporting urgent climate action, the Patrick J. McGovern Foundation has awarded Berkeley Earth a Climate Action Grant in support of its continued contributions to advancing open-source environmental data science.

Using a novel homogenized daily temperature record from Berkeley Earth, the first of its kind, Hausfather’s presentation will outline findings that more maximum daily temperature records have been set in the last decade than previously reported.

As world leaders gather at the COP26 Climate Change Conference to confront the challenge of slowing global warming, Berkeley Earth, a nonprofit independent source of climate change data since 2013, has produced a new resource, Actionable Insights for Policymakers, offering for every country warming scenarios consistent with the 2021 IPCC Report findings.

Ahead of the COP26 conference in Glasgow, Berkeley Earth climate scientists answer your questions about the climate science of a world below 1.5°C.

The awards, announced by the Royal Swedish Academy of Sciences on Tuesday, October 5th, recognized the three scientists for their individual work, the combined effect of which, “provided groundbreaking contributions to our understanding of complex systems,” leading to greater understanding of the complex interactions of physical phenomena involved in global warming and climate change.

Following April’s National Geographic cover story featuring Berkley Earth’s open-source air quality data, we sit down with Berkeley Earth’s climate scientists Dr. Robert Rohde and Dr. Zeke Hausfather to discuss global air quality trends.

We sit down with social entrepreneur, environmental policy innovator, Berkeley Earth Board Director, and In This Together Co-Founder Bill Shireman to discuss the important role of independent climate science in taking a data-driven approach to climate solutions.

2023 was warmest year on Earth since direct observations began. In Berkeley Earth’s analysis 2023 was 1.54 °C above our 1850-1900 average, making it the first year above 1.5 °C. The extreme heat was due to a combination of natural and man-made factors, including global warming and an emerging El Niño event. 17% of the Earth’s surface had a locally warmest year, affecting 2.3 billion people, including significant parts of Asia, South and Central America.

Marking Berkeley Earth’s tenth year of providing independent, open-source analysis of global average temperatures, the 2022 Annual Temperature Report finds that 2022 was nominally the fifth warmest on Earth since 1850. The last eight years have been the eight warmest years on record.

As an eventful year of climate news comes to a close, Berkeley Earth climate scientists Dr. Robert Rohde and Dr. Zeke Hausfather talk with Social Media Manager Kari Hulac about air surface temperature records and the significant warming event in the Arctic region, as well as preview some exciting new research about climate change mitigation efforts.
