The 1.5 ∘C Rescue Mission: A Roadmap for Humanity's Greatest Challenge

Wazzup Pilipinas!? 

A new, comprehensive analysis by Climate Analytics and the Potsdam Institute for Climate Impact Research (PIK) reveals a stark truth: humanity's insufficient climate action has locked the world into a period of overshoot of the Paris Agreement's 1.5 ∘C warming limit. However, the report, titled "Rescuing 1.5 ∘C", provides an urgent and dramatically compelling roadmap—the Highest Possible Ambition (HPA) scenario—that shows it is still within our power to bring warming back down to a safer climate well below 1.5 ∘C before the end of the century.

The message is clear: the 1.5 ∘C limit is not lost, but the cost of delay is staggering, tripling our cumulative exposure to the risks of climate catastrophe.

The Cost of Delay: Deeper and Longer into the Danger Zone

The failure to aggressively cut emissions from 2020-2025 has had irreversible consequences on the climate trajectory. The HPA scenario updates outdated models from the IPCC's Sixth Assessment Report (AR6) to reflect today's higher starting emissions.

The Staggering Climate Impact

The report outlines the new, grim reality of the climate path, contrasting it with what could have been achieved five years ago:

Peak Warming: Global warming is now likely to peak at around 1.7 ∘C. This is 0.1 ∘C higher than the median peak in 1.5 ∘C-aligned AR6 scenarios.

Duration of Overshoot: The world is projected to exceed the 1.5 ∘C limit for approximately 40 years. This is at least a decade longer than the ∼30 years projected in the median AR6 scenarios.

Cumulative Exposure: The total "degree-years" of overshoot in the HPA scenario are calculated at 4.3 ∘C-years, more than triple the 1.3 ∘C-years in the median AR6 scenario. This exponentially increases the risk of crossing irreversible climate tipping points and escalating impacts.

The Accelerated Pace of the Transition

To compensate for lost time, the necessary emissions cuts must now be deeper and faster, leading to a more disruptive economic transition and increased asset stranding.

In the crucial decade of the 2030s, global greenhouse gas emissions must fall by two-thirds—an unprecedented annual reduction rate of 11%. This rapid pace also demands much faster retirement of fossil fuel infrastructure, particularly gas-fired power stations.

The Four Key Levers to Achieve Highest Possible Ambition

The HPA scenario presents a transformative roadmap built on four interlocking, non-negotiable levers. A shortfall in any one area would require unfeasible action in another, leading to increased overshoot.

1. Widespread Electrification Powered by Renewables (The Powerhouse)

The energy system must be overhauled, leveraging the recent "revolution in renewables and batteries".

Electrification Dominance: By 2050, more than two-thirds (64%) of the global energy system must be directly powered by renewable electricity.

Renewable Growth: This transition is underpinned by wind, solar, and battery storage. Global renewable capacity must grow 3.5-fold by 2030 relative to 2022 levels, just ahead of the COP28 tripling goal.

Fossil-Free Power: Both coal and gas must be virtually phased out of the power sector by 2040, with wind and solar supplying over 90% of electricity demand by 2050.

2. A Rapid Fossil Fuel Phaseout

The complete and rapid elimination of fossil fuels is paramount to halt warming.

Immediate Peak: Production and consumption of all fossil fuels must peak immediately in 2025 and fall rapidly thereafter.

Timeline: The global phaseout must see:

Coal: Effectively phased out by the 2040s.

Gas: Effectively phased out in the 2050s.

Oil: Effectively phased out in the 2060s.

Total Elimination: A fossil-free global economy, including non-energy use like chemical feedstocks, is achievable by 2070. Crucially, fossil-CCS (Carbon Capture and Storage) plays only a marginal, temporary role in this scenario.

3. Faster Action on Methane

As a short-lived but potent greenhouse gas, cutting methane is essential to curb peak temperatures.

Reduction Goals: Methane emissions must fall by about 20% by 2030 and 32% by 2035 (relative to 2020 levels).

Driver: The primary driver of these cuts is the energy sector, with emissions from fossil fuel extraction halved in the 2020s and virtually eliminated by mid-century.

4. Carbon Dioxide Removal (CDR) at a Commercial Scale

While no substitute for the fossil fuel phaseout, large-scale carbon removal is the inevitable, complementary action required to draw temperatures back down after they peak.

Scaling: CDR technologies must scale up rapidly from the 2030s, reaching a combined ∼8 GtCO2

​

 /yr by 2050 from Biomass with CCS (BECCS), Direct Air Capture with CCS (DACCS), and Afforestation/Reforestation (A/R).

Resilience: The good news is that the scenario is robust: even if engineered CDR deployment is halved, temperatures would still fall back below 1.5 ∘C by the end of the century.

The Enduring Anchor: 1.5 ∘C Still in Sight

The ultimate outcome of the Highest Possible Ambition scenario is a return to a safe climate. By 2100, global warming is projected to decline to approximately 1.2 ∘C.

As Bill Hare, CEO of Climate Analytics, states: "Overshoot of 1.5 ∘C is a woeful political failure... But this roadmap shows it is still within our power to bring warming back well below 1.5 ∘C by 2100".

The Rescuing 1.5 ∘C report is a call to action, not despair. It reaffirms that the 1.5 ∘C warming limit remains the "enduring legal, political and moral anchor" of the international climate process, guiding the highest possible ambition. The world has a choice: to embrace this disruptive transition and deliver a healthier, fairer, and safer future for all, or risk locking in chaos.

The future is in our collective hands.

Cryosphere on the Brink: Global Ice Loss Threatens Billions, But Urgent Action Can Still Avert Catastrophe!

Wazzup Pilipinas!? 

A new, dramatically urgent assessment from the world's leading cryosphere scientists has unveiled a chilling reality: Global ice loss is dangerously expanding, spelling disaster for billions of people. However, the same report offers a sliver of hope, asserting that the worst impacts can still be avoided if governments course-correct immediately.

The latest research, detailed in the 2025 State of the Cryosphere Report, coordinated by the International Cryosphere Climate Initiative (ICCI) , reveals that current unambitious climate commitments—which lead the world to well over 2 ∘C of warming—will result in catastrophic global ice loss. The report stresses that this damage can still be prevented, but barely.

The Scale of the Crisis

The report integrates the alarming finding that glaciers around the world have lost an average of 273 billion metric tons of ice per year between 2000 and 2023, with losses accelerating in recent years. This accelerating melt has been detailed since the signing of the Paris Agreement in 2015.

Key findings underscore the perilous state of the planet's ice and snow (the cryosphere):

Critical Temperature Thresholds: Latest research notes that thresholds for the stability of polar ice sheets are likely at just 1∘C of warming, and even lower temperatures threaten many glaciers.

Irreversible Changes: Most of these devastating changes will be irreversible for centuries, or even thousands of years.

Near-Total Loss: Regions like the European Alps, Scandinavia, the Rockies of North America, and Iceland would lose at least half their ice at or below a sustained 1 ∘C, and face a loss of all or nearly all ice at 2∘C.

For example, areas such as Scandinavia and western North America are projected to lose all or nearly all ice already at 2 ∘C of warming, though a 1.5 ∘C emissions trajectory could preserve 20% of today’s ice in these regions.

High Mountain Asia at Risk: Even the higher central and eastern parts of High Mountain Asia are projected to lose 60% of existing ice under a 1.5 ∘C emissions scenario, with only 15% remaining at 3.0 ∘C. The Hindu Kush and Karakoram regions stand to lose 40% of ice mass under a 2 ∘C future, but only 15% under a 1.5 ∘C pathway.

Tropical Ice Disappearing: Indonesia’s Puncak Jaya glaciers have already lost more than 99% of their 1850 surface area. New satellite imagery from 2023 and 2024 shows these tropical ice masses have lost as much as 64% of their surface area since the most recent survey in 2018. * Sea Ice Records: Combined Arctic and Antarctica sea ice hit its lowest area ever in February 2025.

Ocean Acidification: This has passed critical thresholds in much of the Arctic and Southern Oceans, reaching non-survivable levels for shelled life in some regions.

Permafrost Emissions: Permafrost is now confirmed as a net source of carbon emissions, releasing more carbon into the atmosphere than these ecosystems absorb.

The Narrow Path to Prevention

The report highlights that the difference between 1.5 ∘C and 2 ∘C pathways is also the difference in the projected levels of water, food, economic and political insecurity in all those regions.

Slowing sea-level rise to a manageable level requires a long-term temperature goal at, or even below 1 ∘C. Staying even at current warming levels of 1.2 ∘C will likely lead to several meters of sea-level rise over coming centuries, exceeding coastal adaptation limits.

The good news is found in the "Highest Possible Ambition" (HPA) pathways. These show that:

Temperatures can be lowered this century through aggressive emissions cuts and land-based carbon dioxide removal.

This would slow and then halt glacier, snow, and sea ice loss, as well as permafrost thaw.

Glacier and snow loss can slow and begin to stabilize by the 2060s.

This rapid action is the difference between facing 3 meters' sea-level rise early next century (with current emissions) versus that amount in one or two thousand years.

"Preserving the Earth's cryosphere now means reaching 1.5 ∘C by 2100 and lowering temperatures towards 1 ∘C thereafter," says Dr. James Kirkham, Chief Scientist to the Ambition on Melting Ice (AMI) high-level group of nations and an author on the Report.

A Call to Action at COP30

The publication of the Report comes as global leaders gather in Belém, Brazil, for the UNFCCC Conference of the Parties (COP30). The site of COP30 itself is vulnerable to climate change impacts.

Dr. Kirkham issued a stern challenge to the policymakers: “Policy makers at COP30 must stop denying this physical reality and finally deliver the deep, rapid and sustained emissions reductions need to protect global security from accelerating ice losses".

"The best and worst part of these findings is that none of this damage is necessary," added Pam Pearson, ICCI's Director. "We have all the tools to change, as the new HPA pathways detail. We just need to use them".

Uwan on the Horizon: How a Potential Super-Typhoon Is Racing Toward the Philippines — What to Expect and How to Prepare

Wazzup Pilipinas!? 

A brooding swirl over the western Pacific is charging westward with a single, terrible mission: to gather strength. What began as a tropical depression well east of Mindanao has been feeding on warm seas and low wind shear, and forecasters now say it may intensify into a super-typhoon before entering the Philippine Area of Responsibility (PAR) as “Uwan.” The time window is tight — entry into PAR is forecast for Friday night to Saturday — and the storm could reach peak intensity while still over open water, raising the specter of landfall at or near its strongest. 

The fast facts — current status and the forecast arc

Where it is now: PAGASA placed the disturbance thousands of kilometres east of northeastern Mindanao as it tracked west-northwest. Observations late this week put its center roughly 1,700–1,985 km east of Mindanao, moving toward the Philippine Sea. 

Intensity trend: The system has already shown steady organization (maximum sustained winds reported near ~55 km/h in early advisories) and most global models suggest further rapid intensification — possibly to super-typhoon strength — while the system traverses the Philippine Sea. 

When it could affect the Philippines: Forecast tracks place Uwan entering the PAR Friday night or Saturday, with impacts on coastal waters and exposed seaboards beginning even before the name is assigned. There is a growing possibility of landfall in northern or central Luzon early next week, though the exact timing and locus remain uncertain. 

Why this storm is dangerous — not just wind but water and surge

When storms strengthen over very warm water they concentrate energy quickly. A storm arriving at peak intensity near land amplifies three cascading threats:

Violent winds capable of demolishing roofs, toppling trees and power lines, and destroying weak structures — especially if Uwan maintains super-typhoon strength near landfall. 

Extreme rainfall over mountainous catchments that can trigger flash floods and catastrophic landslides in upland provinces still saturated from previous systems. The danger multiplies when successive storms keep ground moisture high. 

Storm surge and coastal inundation along exposed eastern and northern seaboards — especially in bays and estuaries where water can pile up. Even before a storm reaches the coast, swells and dangerous rip currents will make seas deadly for fishermen and small craft. 

Who’s most at risk

Based on current model guidance and the typical west-northwest track from the Philippine Sea, the northern and eastern seaboards of Luzon — provinces such as Aurora, Isabela, Cagayan and parts of northeastern Quezon — are among the areas most likely to face the brunt if the track holds. Fishing communities, low-lying coastal barangays, slope-prone villages, and transport hubs servicing ports and inter-island ferries must treat this as a high-consequence threat. (Forecasts remain probabilistic, so other regions should also remain alert.) 

What the agencies are saying

PAGASA and the Office of Civil Defense are actively monitoring the system and have repeatedly warned that landfall at or near peak intensity is a possibility, urging local governments and communities to ready evacuations and preposition assets. News outlets and meteorological analysts echo the warning that the storm could reach super-typhoon force over the weekend. Expect wind signals, coastal advisories, and rainfall watches to be issued and raised in the coming 48–72 hours as model consensus sharpens. 

How to prepare — a checklist for households and local authorities

For households

Assemble or top up a 72-hour emergency kit: water (3–5 litres per person per day), non-perishable food, flashlight with extra batteries, first aid kit, important documents in a waterproof sleeve, phone power bank, masks and sanitation supplies.

Secure loose outdoor items (ladders, tarpaulins, potted plants). Move vehicles to higher ground if flooding is possible.

Identify the nearest evacuation center and plan multiple routes to get there; keep fuel and phone credits ready. Obey evacuation orders promptly.

If you live in a landslide-prone slope or low-lying coastal area, don’t wait for wind signals — move early. 

For local government units and responders

Preposition search and rescue teams, heavy equipment and relief supplies away from likely impact zones but close enough for rapid deployment. Coordinate with regional disaster response clusters.

Clear and mark evacuation centers, ensure sanitation and distancing (COVID-era lessons on safe sheltering still apply), and prepare contingency routes if primary roads are cut by flooding.

Issue clear, repeated public advisories (SMS, radio, social media, barangay volunteers) about expected coastal conditions, port closures, and curfews if needed. 

The bigger picture — why Uwan matters beyond this storm

2025 has already been an active, punishing season across the western Pacific. Communities that are repeatedly battered by multiple storms in a single season face compounding damage: repeated flood cycles, stretched emergency resources, and erosion of social and economic capital. In the past year, storms of similar intensity have forced large evacuations and caused devastating infrastructure losses — a stark reminder that resilience planning must be ongoing, not episodic. 

What to watch over the next 72 hours

PAGASA bulletins and Wind Signal announcements — these are authoritative for local action. Expect updates multiple times daily as the system approaches. 

Model cluster updates (GFS, ECMWF) — look for changes in the predicted track and intensity; small shifts can change which provinces are most threatened. 

Marine advisories and port closures — fishermen and merchant vessels should stay ashore once alerts are issued. 

Final word

Forecasts say Uwan could be among the most powerful storms to approach the Philippines this season. That’s a technical way of saying: this is serious. Do not wait for panic or last-minute orders. Prepare now, help your neighbours prepare, and prioritize life over property. When a storm like Uwan turns from model lines on a map into real wind, rain and surge at your door, the actions you take in the next 24–48 hours can change outcomes for whole communities.
