Carbon Dioxide Spikes to Critical Record, Halfway to Doubling Pre-Industrial Levels
For the first time in recorded history, the concentration of atmospheric carbon dioxide, or CO2, was measured at more than 420 parts per million at the Mauna Loa Observatory on the Big Island of Hawaii, The Washington Post reports. It’s a disconcerting milestone in the human-induced warming of the planet, around the halfway point on our path toward doubling pre-industrial CO2 levels.

Court Tosses Trump Rule Limiting Emissions Regulations
A federal appeals court threw out a Trump administration rule on Monday that would have prevented the Environmental Protection Agency from regulating greenhouse gas emissions from any polluting sector other than power plants. Environmental and public health groups, as well as several states, sued the EPA over the rule, which critics have said is arbitrary and would give a free pass to polluters.
Projected Surge of Lightning Spells More Wildfire Trouble for the Arctic
With the Arctic warming at up to three times the pace of the global average, more lightning storms will invade the High North in a vicious circle that speeds up warming further, a new study found. The increased lightning strikes will ignite wildfires that release carbon dioxide and accelerate the transition of flat mossy tundra to brush and forest landscapes that absorb more solar heat energy, researchers warn.

Climate Migrants Fleeing Storm-Stricken Central America Struggle to Find Refuge
A growing number of Central Americans who have recently fled the region after destructive storms and a growing climate crisis are now finding themselves in migratory limbo, NBC News reports. Seeking asylum in the United States, more than 62,000 people have been denied entry as of January under a rule put in place during the Trump administration.
Want to Buy a Climate-Friendly Refrigerator? Leading Manufacturers Are Finally Providing the Information You Need
Last month, one of our reporters tried to buy a climate-friendly refrigerator but instead got a carbon bomb. Climate-friendly refrigerators are increasingly available but it’s been nearly impossible to identify them from fridges that use HFCs—potent greenhouse gases. Now, the Environmental Protection Agency and leading manufacturers are making it easier to tell which is which.

A Top U.S. Seller of Carbon Offsets Starts Investigating Its Own Projects
The Nature Conservancy, a major environmental nonprofit and a top U.S. seller of carbon offset credits, is conducting an internal review of its offset portfolio following concerns that the projects aren’t actually helping to reduce greenhouse gas emissions as intended, Bloomberg reports. The nonprofit has helped develop dozens of projects that generate credits for financial firms like BlackRock and JPMorgan Chase.
