## Climate Change: Past, Present, and Future### Recent Research Highlights- Long-term trends in heat wave gaps for the New York City metropolitan area over several decades show an alarming decrease in gap length and frequency, suggesting more frequent and severe heat events. (Lin & Colle, Urban Climate)- Permafrost in Svalbard has been melting at an accelerated pace since 1985, with widespread seasonal cycles in calving front position observed due to ocean warming. (Li et al., Nature Communications)- The seasonal cycle of sea level along the U.S. Mid-Atlantic Coast has undergone significant changes, with minimum levels shifting from January to February and amplitude increasing by 65% over the past two decades. (Yang & Chen, Geophysical Research Letters)- Compartmentalization within the fossil fuel industry and government inhibits efforts to address climate denial, with strategies of compartmentalization involving selective accounting, biased reporting, and evasions of responsibilities. (Hendlin & Palazzo, PLOS Climate)- Analysis of data from major fossil fuel industry sectors shows networks of climate obstruction, using tactics of denial and delay to impede climate action. (Kinol et al., PLOS Climate)### Climate Change Impacts- Climate change is linked to roughly a quarter of the extreme fuel moisture deficit during the historic Los Angeles fires of 2023. (Madakumbura et al., Sustainable LA Grand Challenge)- Latest global temperatures reached unprecedented levels in 2024, exceeding the Paris Agreement threshold and breaking multiple greenhouse gas records, contributing to extreme events worldwide. (Copernicus Climate Change Service)### Climate Change Mitigation- A multi-model study suggests that implementing the United States' 2035 emissions reduction targets is technically and economically feasible. (Iyer et al., Nature Communications)### Climate Change Adaptation- A proposed method for analyzing historical adaptation pathways of coupled natural-human systems provides a framework for understanding long-term adaptation processes. (Doeffinger & Siders, Environmental Science & Policy)### Perspectives- Addressing climate change requires recognizing the nonlinear exposure-response associations of heatwaves with mortality. (Liu et al., Nature Communications)- Small islands serve as living laboratories, providing insights into the challenges posed by climate change and sustainable development. (Pathirana, Frontiers in Climate)- The feasibility of climate change mitigation and adaptation strategies can be enhanced by considering near-term benefits and economic returns on investments.
