![]() ![]() ![]() The perception is not well supported with evidence. There is a common perception that extreme weather events are more severe and frequent than formerly. Assuming, for the sake of the argument, that there is longer term warming, it should be noted that Earth has been warming since the peak of the last continental glaciation about 20,000 years ago we are currently living in what is known as an “interglacial.” Consequently, sea level has risen significantly over the last 15,000 years, with a remarkably constant rise in the last 8,000. “The last years have been the warmest since modern record-keeping began.”Īctually, there has been not statistically significant warming for over 8 years. You have no idea what altered inputs will do to the output of this black box. All you know is a chatoic system is changing. And we know…(it’s) going to increase”, no you don’t know. NASA has nothing to do with that, so go ask an economist, a land developer, or a farmer.īy the way, “more extreme events like heatwaves and heavy rainfall and wildfire. The infrastructure you build may not match or handle the weather of a different climate, so a sewer may not take all the rainfall, or a house may not be insulated against colder weather. Water may be where it wasn’t, and not be where it was. Maybe it’ll grow somewhere it never could. If you grow something somewhere, maybe someday you won’t be able to. All NASA can tell you is their satellite data shows climate is changing, which it always does, which is why climate is a term limited to 30 years.Ī change in climate is inconvenient and disruptive. Even if you ask a climatologist, they’ll tell you that climate changes. Meanwhile, NASA doesn’t know or care you don’t ask a space engineer or an astrophysicist or an astronaut about the impact of change on a climate. The first sentence and paragraph is repeated in the fourth or last paragraph and sentence. This article reads like AI-generated gibberish. Does NASA Know About All the Asteroids?.What if an Asteroid Was Going To Hit Earth?.How Did Perseverance Mars Rover Pick Its Landing Spot?.When Was the Last Time an Asteroid Hit Earth?.Is NASA Aware of Any Earth-Threatening Asteroids?.Is NASA Really Crashing a Spacecraft Into an Asteroid?.So why does climate change matter? It’s real. And we’re also developing technologies here at NASA and around the world that can help us limit future warming or respond to the warming that we’re experiencing. So we develop computer models that help us understand how much it might change in the future. We also have tools that can help us better understand and better prepare for future climate change. We know that it’s due to increasing greenhouse gases from human activity. Kate Calvin explains how NASA collects data and develops tools that can help us better understand and prepare for climate change. NASA Chief Scientist and Senior Climate Advisor Dr. Why does climate change matter? Because it’s happening and we’re already feeling its effects around the world. We know more about our planet than we have ever before, and we learn more every day. There are scientists at NASA and around the world that are researching this. These changes are impacting decisions that some people make every day, like a farmer thinking about what crops to grow or a homeowner thinking about flood risk.īut there’s hope. And we know that a lot of those effects are going to increase with more warming. We’re seeing more extreme events like heatwaves and heavy rainfall and wildfire. And we’re seeing some of those effects now. Even a little change in temperature can have big effects. The last years have been the warmest since modern record-keeping began. And what we see is that the planet’s climate is changing. We look at the Earth from space and we measure it on the ground. Climate change is a global issue that has far-reaching environmental, social, and economic consequences, and addressing it requires a coordinated effort on the part of individuals, communities, and governments around the world. Climate change refers to the long-term shift in average weather patterns and conditions that have come to define Earth’s local and global climates. ![]()
