, senior climate scientist

It is now official, 2020 ends the hottest decade on record. The top takeaway is the decadal temperature chart has now become as iconic as the “Keeling Curve,” which has recorded atmospheric carbon dioxide at Mauna Loa Observatory in Hawaii since 1958, and shows a similar upward trend. Read more >

Ask a Scientist: What Should the Biden Administration and Congress Do to Address the Climate Crisis?

, senior writer

For all the promises on climate action that President-elect Biden has made, some nagging questions remain: Given the constraints of a closely divided Congress, how much will the Biden administration truly be able to accomplish? And even with the United States rejoining the Paris accord, will countries live up to its promise to keep the Earth’s temperature in check? For some answers, I turned to Climate and Energy Program Policy Director Rachel Cleetus Read more >

¿Es el Gobernador de Massachusetts, Charlie Baker, serio con respecto al cambio climático y la justicia ambiental? Lo sabremos mañana

, Senior Bilingual Energy Analyst

En inglés

Actualizada el 15 de enero del 2021 a las 14:01: En una movida innecesaria y decepcionante, el Gobernador de Massachusetts, Charlie Baker, vetó la propuesta de ley encaminada a reducir las emisiones de carbono del estado y detener las injusticias ambientales. ¡Lea nuestro comunicado de prensa (en inglés) acá!

Una crucial propuesta de ley para combatir el cambio climático y avanzar la justicia ambiental en Massachusetts está a la espera de ser firmada por el Gobernador Baker antes de la medianoche del 14 de enero (¡quedan pocas HORAS!). La propuesta de ley, “Un Acto Legislativo para Crear una Hoja de Ruta de Próximo Nivel para la Política Climática de Massachusetts” (S2995) es el resultado de años de trabajo, discusiones, negociaciones y muchísimo esfuerzo de un gran número de organizaciones, legisladores, coaliciones y en general, de personas que se preocupan por un mundo saludable en el que podamos vivir las generaciones presentes y futuras.

La noticia del momento es que hay un alto riesgo de que el gobernador simplemente vete la propuesta de ley, incluyendo con no firmarla (un “veto de bolsillo”).

Is Massachusetts Governor Baker Serious about Climate and Environmental Justice? We’ll Know by Tomorrow

, Senior Bilingual Energy Analyst

En español

Update 1/15/2021 at 1:58 pm: In an unnecessary and disappointing move, Massachusetts Gov. Charlie Baker has vetoed a bill that would have strengthened the state’s carbon emissions goals and stop perpetuating environmental injustices. Read our press statement here!

A crucial bill to address climate change and advance environmental justice in the Commonwealth is waiting to be signed by Governor Baker before midnight on January 14 (just HOURS left!). This bill, “An Act Creating a Next-Generation Roadmap for Massachusetts Climate Policy” (S2995), is the result of years of work, discussions, negotiations and a lot of effort from a myriad of organizations, legislators, coalitions and in general, people that care about a healthy and livable world for current and future generations.

The news is that there is a big risk that the governor could simply veto the bill—including by just neglecting to sign it (a “pocket veto”).

, Senior energy analyst

Massachusetts’s next step on addressing climate change has made its way to Gov. Charlie Baker’s desk. The state legislature passed a solid climate-energy-justice bill this week that needs the governor’s signature now to become law. Read more >
