Quartz: Hawaii pledges to become carbon neutral by 2045—the most ambitious goal of any US state

One of the bills cites a study that found that Hawaii could suffer $19 billion worth of damage to private property because of a rise in sea levels. When public infrastructure is included, the damage will likely be a lot higher. That is why it isn’t surprising that the US state most vulnerable to climate change is the one most keen to mitigate its impact. [...]

To be sure, it’s not clear if the state has thought through how hard a net-zero emissions target is to meet. The bill mentions initiatives such as planting trees and improving soil health as means of sequestering carbon, but not technologies such as carbon capture and storage that are proven to reduce emissions on a larger scale. That’s where the greenhouse-gas sequestration task force will help. It has a 2023 deadline to craft a plan that Hawaii can use to reach carbon neutrality. One of the bills also opens the door for the state to participate in carbon-trading programs, such as the one in California, and to use other market-driven tools to cut emissions.

Before Hawaii’s latest moves, Rhode Island was the state with the most ambitious climate goal: cutting emissions by 85% of 1990 levels by 2050. More importantly, Hawaii can now count itself among the most climate-friendly territories in the world. The Maldives aims to become carbon neutral by 2020, Costa Rica by 2021, Norway by 2030, Iceland by 2040, Sweden by 2045, and New Zealand by 2050. The UN’s Intergovernmental Panel on Climate Change has made it clear that more states and countries will need to join this list if the world as a whole is to avoid climate catastrophe.

Bloomberg: Gay-Marriage Clash Throws Costa Rica Presidential Race Wide Open

Costa Rica’s debt and deficit have risen to the highest on record, and its credit rating has been cut repeatedly in recent years. But, forget all that: It is the prospect of legalizing gay marriage that dominated the debate and threatens to turn the Feb. 4 presidential election on its head.

Many religious Costa Ricans were incensed by a Inter-American Court of Human Rights ruling this month in favor of gay marriage, which the government said it would implement. Support for Fabricio Alvarado, an little-known evangelical candidate opposed to the notion, leaped sixfold, propelling him into first place in some polls and spooking investors.

Many investors had been looking to Antonio Alvarez, an opposition candidate who has called for a “fiscal rule” to limit the government’s ability to take on debt, and is proposing to extend the sales tax to goods that aren’t currently covered. He’s now likely to slug it out with Alvarado in a second round of voting on April 1.

Juan Diego Castro, a populist lawyer who is pledging a war on corruption, is in third position in the polls. Alvarado leads decided voters with 22 percent support to 21.4 percent for Alvarez in an Opol Consultores poll of 2,800 people conducted from January 25-27. Castro trailed with 15.7 percent.

IFLScience: Costa Rica Has Been Running On 100% Renewable Electricity For 76 Days... And Counting

Ladies and gentlemen, a round of applause for Costa Rica – this Central American nation has been running on 100 percent renewable electricity for at least 76 consecutive days. This follows on from 150 other days already this year wherein it has only used geothermal and hydrothermal power generation. Last year, a whopping 300 days were fossil fuel-free in terms of electricity generation. [...]

Normally, about 7 percent of its electricity is generated by fossil fuels. Fortunately, particularly heavy rains recently have supercharged the nation’s four huge hydroelectric dams recently, rendering fossil fuel combustion unnecessary. (Weirdly, the surge in rainfall may be attributable to climate change itself.) [...]

Iceland – a far wealthier (GDP $47,500 per person) but far less populous (323,000) country, is comparable in terms of how it produces energy. Like Costa Rica, it has almost no need for other power sources, including wind, nuclear, biomass or fossil fuels.
