A science-and-news query that stays high in every country. This page has 50 important questions and answers. Original explainer for daily search — not a government login or live tracker.
Climate is the long-term pattern of weather; climate change is a shift in those patterns. Today’s global warming is driven mainly by greenhouse gases from burning coal, oil, and gas, plus deforestation. The IPCC assesses the science for governments.
Weather is Tuesday’s storm. Climate is the 30-year story. One cold week does not “disprove” a warming trend any more than one hot day proves it alone.

Answer: the long-run pattern of weather
Think decades, not this afternoon.
Answer: greenhouse gases from fossil fuels
CO₂, methane, and others trap heat.
Answer: lets Earth keep enough heat for life — extra gases overheat it
Venus is the extreme textbook case.
Answer: summarise climate science for policymakers
They are assessment reports, not a single lab.
Answer: absorbs more carbon than it emits (e.g. a healthy forest)
Oceans also take up a lot of heat and carbon.
Answer: living with impacts (flood walls, crops, cooling)
Mitigation means cutting emissions.
Answer: human-caused emissions balanced by removals
Dates and accounting rules are political fights.
Answer: is weather, not proof the climate trend reversed
Trends need long records.
Answer: a shift in the long-run pattern
Think decades, not this afternoon.
Answer: is the main long-lived driver of current warming
Land-use change adds more.
Answer: leaks, wetlands, and livestock
It is stronger per molecule than CO2 over a short horizon.
Answer: a global pact to limit warming and review pledges
National plans (NDCs) sit under it.
Answer: 1.5°C or well below 2°C above pre-industrial levels
Those are policy targets, not a guarantee.
Answer: how much sunlight a surface reflects
Ice is brighter than open water.
Answer: warmer water expanding plus land ice adding volume
Local rise also depends on land motion.
Answer: dissolved CO2 changes seawater chemistry
Shell-building life can struggle.
Answer: a process that amplifies an initial warming
Permafrost carbon release is a feared example.
Answer: cutting emissions or raising removals
Adaptation is living with impacts.
Answer: make emitting cost money so firms cut it
Design details are political.
Answer: wind, solar, and many hydro plants
Firm power and grids still need planning.
Answer: trees grow and are not soon cleared or burned
Land and water limits apply.
Answer: showing rising atmospheric CO2 at Mauna Loa
Seasonal wiggles sit on a rising trend.
Answer: 280 ppm; it is now much higher
The exact current ppm changes; the direction is up.
Answer: a Pacific variability pattern, not the whole long-term trend
It can add a hot year on top of the trend.
Answer: the far north has warmed faster than the global mean
Loss of bright ice is one reason.
Answer: how much more likely an extreme was because of warming
One storm is still not the whole climate.
Answer: releasing carbon and cutting a sink
Tropical clearing is a large term.
Answer: another greenhouse gas, including from fertiliser
Agriculture policy meets climate policy here.
Answer: a bank account
Sinks can saturate or reverse.
Answer: a robust expectation on a warmer baseline
A cold week does not cancel the shift.
Answer: water taking more volume as it warms
It is a big slice of observed rise.
Answer: direct emissions the company owns or controls
Scope 2 is often bought electricity.
Answer: residual human emissions with removals
Accounting rules are fought over.
Answer: run a single lab that invents the weather
It is a review body.
Answer: carbon-neutral in the year you burn them
Regrowth can take decades.
Answer: cities running hotter than nearby rural land
They sit on top of the global trend locally.
Answer: a system that could shift hard once a threshold is crossed
Risk, not a movie date, is the scientific language.
Answer: flood walls, heat plans, and crop switches
It does not replace cutting emissions.
Answer: a liveable Earth; extra gases overheat it
Venus is the extreme textbook case.
Answer: extra carbon and methane stored in frozen ground
That is a feedback risk.
Answer: physics-based tools with uncertainty ranges, not crystal balls
They are tested on past climate too.
Answer: disprove a multi-decade warming trend
Trends need long records.
Answer: the power mix gets cleaner over time
The whole system matters.
Answer: cuts can slow near-term warming
CO2 still dominates the long game.
Answer: marine heat and other stresses
Recovery is not guaranteed after repeat events.
Answer: gases emitted (and sometimes absorbed) on a territory
Trade and consumption footprints can differ.
Answer: speculative and risky, not a substitute for cuts
Ethics and side effects are unresolved.
Answer: amplifies warming as air holds more moisture
It is a feedback more than a policy lever.
Answer: who caused emissions and who is most exposed
Finance for adaptation is part of diplomacy.
Answer: weather versus climate, and mitigation versus adaptation
