  • While we're already feeling the devastating effects

  • of human-caused climate change,

  • governments continue to fall short on making and executing emissions pledges

  • that would help thwart further warming.

  • So, what will our world look like in the next 30 to 80 years,

  • if we continue on the current path?

  • While it's impossible to know exactly how the next decade will unfold,

  • scientists and climate experts have made projections,

  • factoring in the current state of affairs.

  • This future we're about to describe is bleak,

  • but remember there's still time to ensure it doesn't become our reality.

  • It's 2050.

  • We've blown past the 1.5 degree target that world leaders promised to stick to.

  • The Earth has warmed 2 degrees since the 1800s,

  • when the world first started burning fossil fuels in mass scale.

  • Reports on heatwaves and wildfires regularly fill the evening news.

  • Summer days exceed 40 degrees in London and 45 degrees in Delhi,

  • as extreme heat waves are now 8 to 9 times more common.

  • These high temperatures prompt widespread blackouts,

  • as power grids struggle to keep up with the energy demands

  • needed to properly cool homes.

  • Ambulance sirens blare through the night,

  • carrying patients suffering from heatstroke, dehydration, and exhaustion.

  • The southwestern United States, southern Africa, and eastern Australia

  • experience longer, more frequent, and more severe droughts.

  • Meanwhile, the Philippines, Indonesia, and Japan

  • face more frequent heavy rainfall

  • as rising temperatures cause water to evaporate faster,

  • and trap more water in the atmosphere.

  • As the weather becomes more erratic,

  • some communities are unable to keep pace with rebuilding

  • what's constantly destroyed.

  • Many move to cities,

  • where they face housing shortages and a lack of jobs.

  • A resource squeeze is felt in newborn intensive care wards,

  • as the rising temperature and air pollution

  • cause higher rates of premature and underweight births.

  • More children develop asthma and respiratory disease,

  • and rates balloon in communities regularly exposed to forest fire smoke.

  • The global emissions added to the atmosphere each year

  • finally start to level off, thanks to government action,

  • but it's decades too late.

  • We fail to reach net zero in time.

  • As a result, by 2100 the Earth has warmed another 0.5 to 1.5 degrees.

  • Over half of our remaining glaciers have melted.

  • As the sea heats up, its volume increases due to thermal expansion.

  • Together, this elevates sea level by well over a meter.

  • Entire nations, like the Marshall Islands and Tuvalu, are uninhabitable

  • as large swaths of their islands are submerged.

  • Some islands, like the Maldives,

  • spend billions building interconnected rafts

  • that house apartments, schools, and restaurants

  • that float above its drowned cities.

  • Resettled climate migrants in Jakarta, Mumbai, and Lagos

  • are forced to abandon their homes once again,

  • as rising tides and extreme storms flood buildings and crumble infrastructure.

  • Overall, 250 million people are displaced.

  • Some affluent cities like New York and Shanghai attempt to adapt,

  • elevating buildings and roadways.

  • Ten-meter-tall seawalls line the cities' coasts.

  • Children learn about extinct sea life which once inhabited the ocean's reefs,

  • all of which have vanished thanks to rising surface water temperatures.

  • Grocery prices skyrocket,

  • as food and water scarcity touch all communities.

  • Fruits and products long grown in the tropics and subtropics

  • rarely show up on shelves,

  • as intense heat waves paired with increasing humidity

  • make it deadly for farmers to work outdoors.

  • Unpredictable heatwaves, droughts, and floods

  • cripple small-scale farmers in Africa, Asia, and South America,

  • who previously produced one-third of the world's food.

  • Hundreds of millions of people are pushed into hunger and famine.

  • Climate predictions can feel overwhelming and terrifying.

  • Yet many of the experts responsible for these assessments remain optimistic.

  • Since countries have first begun taking steps to lower their emissions,

  • warming projections have shifted downwards.

  • In less than a decade, we've reduced our projected emission rates

  • so that we're no longer on track to hit nearly 4 degrees of warming.

  • Policies that invest in renewable energy sources,

  • cut fossil fuel production, support electric transportation,

  • protect our forests, and regulate industry

  • can help mitigate the worst effects of climate change.

  • But climate experts have also stressed that current policies and pledges

  • don't go far enoughin speed or scale.

  • Enacting real change will require bold solutions,

  • innovations, and collective action.

  • There's still time to rewrite our future, and every tenth of a degree counts.
