Hurricane Lane is already a landmark storm, having set a record for the strongest hurricane to get so close to Hawaii since modern records began. It could soon set more milestones if it moves within 65 nautical miles of Maui and Oahu on Friday and Saturday.
Why this matters: Hawaii has historically been protected against hurricanes because sea surface temperatures near the islands are typically too cold to support a significant tropical cyclone. That's not the case this year, and is not expected to be the case in the future as the ocean warms in response to increasing amounts of greenhouse gases in the air.
A new paper from Carnegie Mellon University didn't get much attention, but it tackles a huge topic: the challenge of cutting carbon emissions from the energy-hungry trucking sector.
One takeaway is that trains can play a big role, but that would require a reversal of freight industry trends worldwide that favor highways.

Category 3 Hurricane Lane is slowly churning northward toward Hawaii, affecting the Big Island and Maui on Thursday before lumbering toward Oahu and Kauai in coming days.
Why it matters: This storm is the most intense hurricane ever to come so close to Hawaii. The storm threatens the islands with upwards of 2 feet of rain, deadly surf of 20 feet or higher, and intense hurricane force winds.
Sea level rise may seem like a far-off threat, but a growing number of new studies, including one out Thursday, shows that real estate markets have already started responding to increased flooding risks by reducing prices of vulnerable homes.
The bottom line: According to a new report by the nonprofit First Street Foundation, housing values in New York, New Jersey and Connecticut dropped $6.7 billion from 2005 to 2017 due to flooding related to sea level rise. Combined with their prior analysis of 5 southeastern coastal states with $7.4 billion in lost home value, the total loss in 8 states since 2005 has been $14.1 billion.
The big picture: The EPA is claiming to meet its mandate to regulate carbon emissions, while critics say ACE is yet another coal bailout scheme. Yet market forces might ultimately make the new rule moot.
Colorado’s candidates for governor from each party, speaking at an industry event in Denver on Wednesday, both expressed opposition to a likely ballot initiative that would significantly curtail oil and gas production in the state.
Why it matters: The opposition shows the influence and large economic footprint of the oil and gas industry in Colorado despite intense environmental and local resistance to increased development. Colorado, an important political battleground, is America’s fifth-largest gas-producing and seventh-largest oil-producing state.
A Danish cargo container vessel is about to set out on a voyage that will be a milestone in the opening of Arctic waters to marine shipping — and it's a direct result of climate change.
Why it matters: The Arctic has been warming at least twice as fast as the rest of the globe, and sea ice has declined sharply since 1979. As the ice melts, Arctic shipping routes are becoming more attractive as an alternative to sailing through the Suez Canal.
Hurricane Lane has come closer to Hawaii than any Category 5 storm has come in modern records, and it threatens to unleash life-threatening destruction as it approaches the islands starting late Wednesday and lasting into Saturday, according to the National Hurricane Center.
Why it matters: The storm's exact track is still uncertain, with some computer models projecting it will zip out to sea south of Hawaii, and others showing a devastating near-direct hit on one or more islands. Official forecasts show it will come close enough to produce damaging winds, deadly flash floods from upwards of 2 feet of rain, and pounding "extreme" surf. Waves could exceed 20 feet on south facing shorelines.
