To limit warming to 1.5℃ above pre-industrial levels, we'll need to cut global emissions by 7.6% each year this decade. It's difficult, but not impossible.
Greenland’s ice sheet suffered major melting in July 2019, dumping billions of tons of meltwater into the Atlantic Ocena.
The UN body responsible for communicating the science of climate breakdown has released its long-awaited report on how we're changing our ice and oceans. In a nutshell, the news isn't good.
Warmer temperatures could lead to more zones of the country that make good breeding sites for mosquitoes.

Is our changing climate making regions of the US more suitable for ticks and mosquitoes that spread diseases? Or is the climate changing human physiology making us more vulnerable?

Conservative skeptics of climate change may support projects focused on 'resilience' – for example, preparing a community for future major weather events.

There are some good explanations for the mismatch between regional support for climate action and the areas where renewable energy is making the biggest inroads.

After declining for nearly a decade, the number of hungry people in the world is growing again. Climate change, which is disrupting weather patterns that farmers rely on, is a major cause.
Deadly debris flows came to Los Angeles after heavy rain pounded wildfire-scarred land.

One natural disaster can exacerbate the effects of others – think landslides after wildfires. This means engineers and planners need to rethink how they assess and prepare for risk.
Miami is investing hundreds of millions of dollars to raise roads in response to rising sea levels.

Infrastructure systems – roads, water treatment systems, power grid – can't be built the same ways as in the past. What's a better roadmap for the future?
High school students at the University of Maine Farmington’s Upward Bound program playing the World Climate simulation.
In the 'World Climate' simulation, people play delegates to UN climate negotiations and work to strike an agreement that meets global climate goals. Playing it has made thousands want to take action.

Rising temperatures will not only hurt people in the future. Many are feeling the effects now. Those who work outdoors, those who have certain chronic conditions and the elderly are vulnerable.
Damage from Hurricane Michael and other storms may lead to higher insurance premiums.
Convincing people to see and appreciate the threats posed by climate change is one of the great challenges of our day. Insurers may be able to succeed where scientists and educators have failed.
2016’s warm winter meant not enough snow for the start of the Iditarod sled dog race in Anchorage, so it was brought by train from 360 miles north.
For everyone from traditional hunters to the military, the National Park Service to the oil industry, climate change is the new reality in Alaska. Government, residents and businesses are all trying to adapt.
Bioenergy Carbon Capture and Sequestration, known as BECCS, is one of the technologies we may need to limit warming to 1.5 degrees.
Delays on climate action to reduce emissions means that we may have to consider technologies that strip carbon dioxide from the atmosphere. But that will come at a cost.

A big spill in Michigan's Straits of Mackinac could have devastating consequences. But does replacing the pipeline running beneath it make sense in a warming world?
How can we hold governments accountable to their climate commitments? A recent case might hold the answer.

Climate scientists have set out how we could limit global warming, but their scenarios are not at all realistic.
Dairy and livestock farming will not be viable over much of the subcontinent at the current rate of warming.
Staying below 1.5°C will require urgent, deep and radical changes in almost every aspect of our lives.
The kind of climate action outlined by the ubiquitous climate checklists won't be enough.
Without rapid and dramatic changes, the world will face a higher risk of extreme weather and other effects of climate change.

The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.

Limiting human-induced warming will be tough, given where we start from.
