There was a lot of attention paid to Greta Thunberg this week.

And rightfully so.

On Wednesday, Time magazine named the Swedish teen climate activist its Person of the Year.

That same day, in Madrid, she addressed world leaders and diplomats at the COP 25 United Nations climate summit.

And a day later, the president of the United States of America took to trolling the 16 year old on Twitter, which came two days after Brazilian president Jair Bolsonaro called her a "brat." (In both cases, Thunberg responded by making the verbal barbs part of her Twitter bio.)

If given the choice, I'd guess Thunberg hoped what most people paid the most attention was her speech at COP 25. But not just the buzzy parts.

Thunberg said while she's learned from her year and a half in the global spotlight that beginning a speech with something personal or emotional can help grab attention, she'd avoid that this time. "Because then those phrases are all that people focus on."

"They don't remember the facts, the very reason why I say those things in the first place," she said. "We no longer have time to leave out the science. For about a year, I have been constantly talking about our rapidly declining carbon budgets, over and over again. But since that is still being ignored, I will just keep repeating it."

We hear you, Greta.

And in that spirit, we are highlighting here the science portions of Thunberg's speech:

  • "In chapter 2, on page 108, in the SR 1.5 IPCC report that came out last year, it says that if we are to have a 67% chance of limiting the global temperature rise to below 1.5 degrees Celsius, we had on Jan. 1, 2018, 420 gigatons of CO2 left to emit in that budget." Here's the U.N. Intergovernmental Panel on Climate Change report she is citing.
  • "And of course, that number is much lower today, as we emit about 42 gigatons of CO2 every year, including land use. With today's emissions levels, that remaining budget will be gone within about 8 years." That point is visually illustrated by the Carbon Clock created by Germany's Mercator Research Institute on Global Commons and Climate Change. Thunberg went on to say that the numbers are "the current best available science," and they didn't address equity in terms of richer, more emitting countries carrying a larger share of carbon reduction efforts — a point made repeatedly by the Vatican and Catholic organizations.
  • "The approximate 67% chance budget is the one with the highest odds given by the IPCC. And now we have less than 340 gigatons of CO2 left to emit in that budget to share fairly. And why is it so important to stay below 1.5 degrees? Because even at 1 degree, people are dying from the climate crisis. Because that is what the united science calls for to avoid destabilizing the climate, so that we have the best possible chance to avoid setting off irreversible chain reactions, such as melting glaciers, polar ice and thawing arctic permafrost. Every fraction of a degree matters." The IPCC 1.5 report found that average global temperature rise of 2 C, compared to 1.5 C, would expose 420 million more people to severe heatwaves and 10 million more to risks brought by rising seas, while nearly wiping out all the world's coral reef and expanding Arctic summers without sea ice to once per decade, compared to once a century. The planet has already warmed 1 C since the late 1800s, and is on pace to reach 3 C by the end of the century. An analysis by the Washington Post this year found about 20% of the planet has already warmed by 1.5 C.

"So there it is again," Thunberg said. "This is my message. This is what I want you to focus on."

She added: "So please tell me, how do you react to these numbers without feeling at least some level of panic? How do you respond to the fact that basically nothing is being done about this without feeling the slightest bit of anger? And how do you communicate this without sounding alarmist? I would really like to know."

A look at what's new on EarthBeat this week:

  • As part of the annual World Day of Peace message, Pope Francis called the global community to "an ecological conversion," saying "We need to change the way we think and see things, and to become more open to encountering others and accepting the gift of creation." NCR Vatican correspondent Joshua McElwee has the story from Rome.
  • At the "Endangered Earth" exhibit at Manhattan's Ceres Gallery, 10 artists explore climate change through "beautiful images of imperiled nature" and "dramatic scenes of environmental degradation," all of which "commands your reflection on the extinction of species and the depletion of the world's water supply," writes Jesuit Fr. Leo O'Donovan. If you happen to be in New York City, the exhibit closes Saturday.
  • Franciscan Sr. Shannon Schrein and NCR national correspondent Heidi Schlumpf offered reflections on eco-theologian Sallie McFague, who died at age 86 last month. Schrein described McFague's "panentheistic approach" as one that "enriches our understanding of God and our relationship with one another and all of creation."
  • In the latest Small Earth Story, Russ Mancl of northern Wisconsin describes how the Sisters of Mercy of the Holy Cross help local farmers make their harvests more accessible to the 12-county region.
  • Have you seen the new film "Dark Waters" yet? Religion News Service sat down with actor/producer Mark Ruffalo to talk about how it blends film and faith-fueled activism. The movie tells the real-life story of a West Virginia community exposed to chemical waste from a DuPont plant. (The attorney representing the community is Catholic.)

Other climate-related news from this week:

  • Today is the last scheduled day of COP 25. As negotiations worked down to the wire, climate activists continued to demand that governments put science above narrow political interests. (Reuters)
  • On Wednesday, the European Union passed a major economic plan billed the "European Green Deal," which aims to cut carbon emissions in half by 2030 and reach net-zero carbon by 2050. Poland, however, has opted out of the mid-century target. (The Guardian)
  • New York state judge ruled on Tuesday that Exxon Mobil did not defraud shareholders in its accounting of the costs of climate change regulation. (Inside Climate News)
  • Methane, a potent greenhouse gas, is invisible to the naked eye, so The New York Times took a specialized camera to oilfields in West Texas to capture images of its large-scale release, as the Trump administration moves to lift regulations that would curtail methane leaks. (The New York Times)
  • NOAA released its annual Arctic report card this week, finding the region may have crossed a consequential threshold by becoming a net emitter of carbon. (The Washington Post)
  • What is a "supertree" and what do they have to do with climate change? Vox has the answers to both questions. (Vox)

Closing beat: 

With Christmas fast approaching, the season for many is a time of abundant cheer, good will … and wrapping paper.

How do you attempt to limit excess waste during the holidays? Maybe you reuse packaging and wrapping paper. Or perhaps shop local to reduce your gifts' carbon footprints. Let us know your strategies by emailing me at the address below.

Thanks for reading.
