This week’s developments in climate change highlight key actions and concerns in the United States and globally. U.S. Climate Alliance co-chairs, Governors Hochul of New York and Lujan Grisham of New Mexico, responded strongly to a recent executive order by former President Trump that targets state-level climate regulations. The Alliance—comprising governors from 24 states—reaffirmed their commitment to reducing greenhouse gas emissions despite federal opposition. The coalition has already succeeded in lowering emissions by 19 percent from 2005 levels while growing their collective GDP by 30 percent and remains on track to achieve a 26 percent reduction by 2025. Leaders continue to prioritize clean energy jobs, public health protections, and pre-disaster planning across participating states.
Meanwhile, the NOAA announced that La Niña conditions in the tropical Pacific have ended and neutral conditions are expected to persist through summer. This shift could have significant implications for weather patterns in the United States, such as reduced risks of drought in the Southwest. However, experts caution that long-term predictions remain uncertain during this transitional phase known as the “spring predictability barrier.”
The United States is also gearing up for major climate events. The US Climate Action Summit is set to take place in Washington, D.C., later this month. This summit will provide a platform for policymakers, climate activists, and corporate leaders to discuss strategies to combat climate change. Key sessions include a focus on the intersection of climate and health, as well as forums for leadership commitments to tackle U.S.-specific climate challenges.
In Texas, EarthX 2025, the world’s largest environmental expo, will be held in Dallas from April 21 to 25. This event aims to bridge the gap between sustainability innovators, policymakers, and businesses. Organizers hope to inspire actionable partnerships and public awareness about clean energy, conservation technology, and sustainable agriculture.
Globally, new studies and policy shifts continue to shape the climate landscape. A NASA-funded report underscores the critical role of human-induced land-use changes, such as deforestation, in exacerbating climate change. Across the Atlantic, international forums like the Global Landscapes Forum in Germany are addressing forest conservation and the fight against biodiversity loss as essential elements of climate strategies.
Additionally, controversy surrounds recent executive orders by former President Trump to reverse climate protections, including efforts to boost coal and limit states’ ability to pass environmentally focused laws. These actions worry climate advocates, who warn of the potential damage to renewable energy growth and emission reductions in the United States.
