Jakarta, Jurnas.com – Studi terbaru mengungkap lapisan sedimen lunak yang tersembunyi di bawah hamparan es Greenland sebagai faktor kunci yang mempercepat laju pencairan gletser menuju laut. Temuan ini memberi peringatan serius bagi dunia karena berpengaruh langsung terhadap kecepatan kenaikan permukaan air laut global.
Studi ini menunjukkan bahwa sedimen setebal hingga 200 meter berada di bawah sebagian besar lapisan es Greenland, membuat gletser meluncur lebih cepat dibanding jika berada di atas batuan keras. Lapisan lunak ini bekerja layaknya “pelumas” alami yang mengurangi gesekan antara es dan dasar bumi.

The inflation Reduction act of 2022 (IRA), signed into law on August 16, 2022, represents a landmark piece of legislation in the United States, aiming to lower healthcare costs, address climate change, adn reduce the federal deficit. It achieves these goals through a combination of tax provisions, investments in clean energy, and prescription drug price negotiation.
What is the Inflation Reduction Act?
The Inflation Reduction Act is a United States federal law designed to invest in climate and energy programs, lower healthcare costs, and make the tax system more equitable. It’s officially designated as public Law 117-169.
Key provisions & Climate Change Investments
A meaningful portion of the IRA focuses on combating climate change through substantial investments in clean energy technologies. The Act provides tax credits and incentives for renewable energy production, energy efficiency improvements, and the adoption of electric vehicles.

- Investments in Clean Energy Manufacturing: The IRA allocates funding to support domestic manufacturing of clean energy technologies, aiming to create jobs and strengthen the U.S. supply chain. white House Briefing Room – Inflation Reduction Act
Healthcare Provisions and Prescription Drug Costs
The Inflation Reduction Act directly addresses healthcare costs,particularly prescription drug prices,by allowing Medicare to negotiate prices for certain high-cost medications. This is a major shift in policy, as Medicare previously was prohibited from directly negotiating drug prices.
Medicare Drug Price Negotiation
Beginning in 2026, the IRA authorizes Medicare to negotiate the prices of 10 high-cost drugs covered under Medicare Part D. This negotiation process is phased in over several years, with the number of drugs subject to negotiation increasing over time.
The Congressional Budget Office (CBO) estimates that Medicare drug price negotiation will save the federal government approximately $101.4 billion over ten years (2023-2032). CBO – Budgetary Effects of the inflation Reduction Act
Affordable Care Act (ACA) Subsidies
The IRA extends enhanced premium tax credits for health insurance purchased through the Affordable Care Act marketplaces through 2025, preventing premium increases for millions of Americans. CMS – Inflation Reduction act lowers Health Care Costs
Tax Provisions and Deficit Reduction
The Inflation Reduction Act includes several tax provisions designed to raise revenue and reduce the federal deficit. These provisions primarily target large corporations and high-income earners.
Corporate Minimum Tax
The IRA establishes a 15% minimum tax on corporations with average annual financial statement income exceeding $1 billion. This aims to ensure that profitable corporations pay a minimum level of tax, even if they utilize deductions and credits to reduce their taxable income.
